Revision	Date	Author	Comments
1.6	02-Jul-2024	riastradh	drm: Update drm2netbsd to prepare for new import.
1.5	19-Dec-2021	riastradh	branches: 1.5.10; One more file by hand.
1.4	19-Dec-2021	riastradh	Add a couple more make variables.
1.3	19-Dec-2021	riastradh	Set CONFIG_DRM_VM=1, apparently needed for nouveau now. Author: Maya Rashish <maya@NetBSD.org>
1.2	27-Aug-2018	riastradh	branches: 1.2.2; 1.2.6; drm_fb_helper.c got lost in the merge, restore it.
1.1	27-Aug-2018	riastradh	New script to generate files.drmkms from Linux Makefile.
1.2.6.2	10-Jun-2019	christos	Sync with HEAD
1.2.6.1	27-Aug-2018	christos	file drm2netbsd was added on branch phil-wifi on 2019-06-10 22:08:30 +0000
1.2.2.2	06-Sep-2018	pgoyette	Sync with HEAD Resolve a couple of conflicts (result of the uimin/uimax changes)
1.2.2.1	27-Aug-2018	pgoyette	file drm2netbsd was added on branch pgoyette-compat on 2018-09-06 06:56:35 +0000
1.5.10.1	02-Aug-2025	perseant	Sync with HEAD
1.7	19-Jul-2022	riastradh	drm: Nix drm_agp_borrow. This horrible kludge dates from before I understood the relation of genfb_pci and pci drm drivers in the old and new worlds of drm. The only user of it, in i915, was changed to use agp_i810_borrow directly in the last drm update, so this hack can die.
1.6	19-Dec-2021	riastradh	Make ourselves less dependent on drmP.h, removed upstream. This causes some trouble as CONFIG_* lines might not be appropriately defined. A few declarations remain in drmP.h so it's not gone. Author: Maya Rashish <maya@NetBSD.org>
1.5	19-Dec-2021	riastradh	drm_agp_clear got renamed to drm_agp_legacy_clear.
1.4	19-Dec-2021	riastradh	Include drm_internal.h by "../dist/drm/drm_internal.h".
1.3	30-Aug-2018	mrg	branches: 1.3.2; 1.3.6; if hooks init works, store the hooks in the agp. fixes start up crash on an old radeon laptop. from @riastradh. the console also now works, unlike previous drm2, where eg, the problems from PR#49744 are seen. unfortunately, i got a crash starting X, and no ddb yet, so we can't re-enable the r100/r200 parts here yet. once this is known to be working we can delete the old radeondrm code, and remove the hacks to disable drm2 there.
1.2	30-Aug-2018	tnn	initialize error variable
1.1	28-Aug-2018	riastradh	Rework PCI and AGP conditionalization. - Push drm_pci_set_unique into driver callback. - Eliminate drm_pci_set_unique_hook. - Gather all drm_agp_* functions into struct drm_agp_hooks. - Replace the nonsensical old atomic garbage by serious locking. - Make drm_agpsupport.c its own module. - Eliminate NDRMKMS_PCI. - Use NAGP from "agp.h" only in drm_module.c for horrible hack. => See comment in file for rationale. - Always define CONFIG_PCI=1 and CONFIG_AGP=1. - Always go through the drm_agp_* function hooks. - Ifdef out nouveau agp stuff that doesn't go through drm_agp_* for reasons that I'm too frustrated to figure out tonight. - pci_iomap no longer automagically does agp_i810_borrow. => Use drm_agp_borrow instead.
1.3.6.2	10-Jun-2019	christos	Sync with HEAD
1.3.6.1	30-Aug-2018	christos	file drm_agp_hook.c was added on branch phil-wifi on 2019-06-10 22:08:30 +0000
1.3.2.2	06-Sep-2018	pgoyette	Sync with HEAD Resolve a couple of conflicts (result of the uimin/uimax changes)
1.3.2.1	30-Aug-2018	pgoyette	file drm_agp_hook.c was added on branch pgoyette-compat on 2018-09-06 06:56:35 +0000
1.19	19-Jul-2022	riastradh	drm: Make drm_clflush_* noop on alpha. As far as I know there is no need for this; the CPU has weak ordering on loads and stores requiring ordering barriers, but I/O devices participate in the CPU's cache protocol for access to main memory so there's never any need for explicit cache flushes.
1.18	19-Dec-2021	riastradh	drm: Another pass over i915 and some supporting logic. This makes a shim around sg_table, which essentially represents two things: 1. an array of pages (roughly corresponding to bus_dma_segment_t[]) 2. an array of DMA addresses stored in a bus_dmamap_t Both parts are optional; different parts of i915 use sg_tables to pass around one or both of the two parts. This helps to reduce the ifdefs by quite a bit, although it's not always clear which part of an sg_table any particular interface is actually using which is why I was reluctant to do this before.
1.17	19-Dec-2021	riastradh	drm: Nix use of uvm pglist. Just use arrays of page pointers.
1.16	19-Dec-2021	riastradh	Make ourselves less dependent on drmP.h, removed upstream. This causes some trouble as CONFIG_* lines might not be appropriately defined. A few declarations remain in drmP.h so it's not gone. Author: Maya Rashish <maya@NetBSD.org>
1.15	19-Dec-2021	riastradh	drm_clflush_* decls moved to drm_cache.h.
1.14	05-Sep-2020	maxv	x86: fix several CPUID flags - Rename: CPUID_PN -> CPUID_PSN CPUID_CFLUSH -> CPUID_CLFSH CPUID_SBF -> CPUID_PBE CPUID_LZCNT -> CPUID_ABM CPUID_P1GB -> CPUID_PAGE1GB CPUID2_PCLMUL -> CPUID2_PCLMULQDQ CPUID2_CID -> CPUID2_CNXTID CPUID2_xTPR -> CPUID2_XTPR CPUID2_AES -> CPUID2_AESNI To match the x86 specification and the other OSes. - Remove: CPUID_B10, CPUID_B20, CPUID_IA64. They do not exist.
1.13	23-Jan-2019	jmcneill	branches: 1.13.4; skip clflush on aarch64, too
1.12	27-Aug-2018	riastradh	Draft sparc cache flushing.
1.11	27-Aug-2018	riastradh	Factor mfence out. Simplify a little.
1.10	27-Aug-2018	riastradh	Need sync after a series of dcbf's on powerpc.
1.9	27-Aug-2018	riastradh	Implement drm_md_clflush_* for powerpc with dcbf.
1.8	17-Oct-2015	jmcneill	branches: 1.8.10; 1.8.16; 1.8.18; skip clflush on arm
1.7	17-Oct-2015	jmcneill	machine/cpufunc.h is MD, move it to i386/amd64 block
1.6	06-Mar-2015	riastradh	Remove local definition of wbinvd.
1.5	06-Mar-2015	riastradh	Use x86_mfence explicitly, not membar_sync, just to be clear.
1.4	04-Mar-2015	riastradh	CLFLUSH needs to be surrounded by membars. While here, round everything to a multiple of the cache line size.
1.3	16-Jul-2014	riastradh	branches: 1.3.2; 1.3.4; 1.3.6; Make it build and boot on my test machines. Screen blanks on boot on the Ivy Bridge system with DRM error in cpt_serr_int_handler: PCH transcoder A FIFO underrun But after that everything is OK. Appears to be an upstream problem. To investigate... I think there's a cache flushing issue somewhere -- there are little display artefacts on my T60.
1.2	18-Mar-2014	riastradh	branches: 1.2.2; 1.2.4; 1.2.6; Merge riastradh-drm2 to HEAD.

1.16	26-Sep-2021	thorpej	Change the kqueue filterops::f_isfd field to filterops::f_flags, and define a flag FILTEROP_ISFD that has the meaning of the prior f_isfd. Field and flag name aligned with OpenBSD. This does not constitute a functional or ABI change, as the field location and size, and the value placed in that field, are the same as the previous code, but we're bumping __NetBSD_Version__ so 3rd-party module source code can adapt, as needed. NetBSD 9.99.89

1.14	16-Apr-2019	mrg	branches: 1.14.4; 1.14.14; fix various problems i've seen where cv_wait() return ERESTART, which is -3 in netbsd, which we have mapped linux ERESTARTSYS to. this has a problem because linux code often returns errors and pointers in the same value, and pointer values between -4095 and -1 are considered as error returns, but -3 ends up as 3 and thus is not considered an error, and mayhem ensues. with this in place my kabylake system seems actually stable, i have not triggered any of my prior issues in almost 4 weeks now. Taylor asked me to write up a description and then wrote most of the text below for me :-) In Linux code, we always work with ERESTARTSYS so the code meaning start over is a positive NetBSD errno safe for PTR_ERR/ERR_PTR. To achieve this: 1. adapt all cv_waits that return to Linux so they map ERESTART to ERESTARTSYS, and 2. adapt all returns to userland so they convert ERESTARTSYS to ERESTART. Leave EINTR and all other error codes alone.
1.13	21-Dec-2018	maya	Expose nvif ioctl interface. nvif is a variable length (nested..) ioctl, so it doesn't match the usual drm_ioctl interface. linux uses a shim to override the ioctl function for nouveau to allow this, do the same. fixes 3D acceleration with nouveau. from riastradh.
1.12	28-Aug-2018	riastradh	branches: 1.12.2; Rework PCI and AGP conditionalization. - Push drm_pci_set_unique into driver callback. - Eliminate drm_pci_set_unique_hook. - Gather all drm_agp_* functions into struct drm_agp_hooks. - Replace the nonsensical old atomic garbage by serious locking. - Make drm_agpsupport.c its own module. - Eliminate NDRMKMS_PCI. - Use NAGP from "agp.h" only in drm_module.c for horrible hack. => See comment in file for rationale. - Always define CONFIG_PCI=1 and CONFIG_AGP=1. - Always go through the drm_agp_* function hooks. - Ifdef out nouveau agp stuff that doesn't go through drm_agp_* for reasons that I'm too frustrated to figure out tonight. - pci_iomap no longer automagically does agp_i810_borrow. => Use drm_agp_borrow instead.

sys/external/bsd/drm2/dist/drm/drm_gem.c: revision 1.24 sys/arch/xen/xen/xpci_xenbus.c: revision 1.29 drm: Eliminate __HAVE_ATOMIC_AS_MEMBAR conditionals. Discussed on tech-kern: https://mail-index.netbsd.org/tech-kern/2023/02/23/msg028729.html linux asm/barrier.h: Fix !MULTIPROCESSOR build. remove "nouveau" from a comment. noted by jmcneill. drm: KASSERT(A && B) -> KASSERT(A); KASSERT(B) comment a function that has a clear overbounds read but it isn't used. found by GCC 12. nix the NetBSD specific GEM_BUG_ON(). avoids GCC 12 warnings, and matches upstream closer. avoid uninitialised variable usage in drm_gem_cma_create_internal(). in the case nothing has returned 'error', 'nsegs' and the dma info are (potentially) uninitialised, so consider this an error. found by GCC 12. avoid a GCC 12 warning. there's a 1-element long array and a loop conditional that tries to see if indexes for it are not identical. as these indexes will always both be 0, the only valid index, the condition is always false. GCC 12 triggers a strange warning on this code that can never run (see below), so simply assert the array size is 1 and comment the rest. amdgpu_dc_stream.c:470:55: error: array subscript [0, 0] is outside array bounds of 'struct dc_writeback_info[1]' [-Werror=array-bounds] 470 \| stream->writeback_info[j] = stream->writeback_info[i]; convert a KASSERT() into an if () panic() sequence to appease GCC 12. OK riastradh@. drm: Fix conditionals around drmkms_pci and agp. Kernel should build now with all pci drm drivers stripped out but DRM_LEGACY still enabled. (Might not be very useful, but it'll build. Maybe we should also have DRM_LEGACY_PCI so those drivers can be modloaded later.) drmkms: Fix module build. avoid an unlikely array bounds issue picked up by GCC 12. nvkm_pcie_speed() can return -1, which is then used as an array index, so make this default return PCIe 1.0 speeds. drm: enable almost all PCIe functionality linux_pci.c revisions 1.24 and 1.25 implemented most of the remaining missing PCIe backends, but only enabled them for some amdgpu portions. this enables all code marked with "XXX amdgpu pcie", "XXX radeon pcie", and "XXX pcie speed". for most of it, simply removing #ifndefs __NetBSD__ to enable compliation was required, once the new "bus->max_bus_speed" member was added to struct pci_bus. add an "always fails" backend for pci_enable_atomic_ops_to_root() which seems to only be necessary for virtual GPU functionality (and could be implemented if needed.) tested on radeon 5450, 7750, R7 240 [radeon], and RX 550 [amdgpu], and nvidia 750 and 1030 [nouveau]. this still does not quite work on nvidia cards. there are two problems that remain: - the call to set the link speed is skipped because the speed is set to the default value of "-1". nvkm_pcie_set_link() will actually determine the right value for this and for some cards, calling this function if the current speed is -1 helps set the link speed. it may be that on linux other paths we don't have enabled properly would set this (there's one via debugfs, and a jetson specific one, though perhaps setting either AC or DC speed values as boot options (after hooking up these for netbsd) would currently work. - worse, cards newer than kepler - geforce 900, 1000, and newer, are all lacking the backing support to set pcie link speed. the GT 1030 card i have been testing with remains at pcie 1.0. radeon: fix and enable ACPI methods for getting ROM BIOS The hacky way of getting the BIOS mapped only works on x86. ACPI should be preferred if available. Makes BIOS reading though VFCT work on aarch64 with EDK2. (But only if EDK2 has POSTed the GPU.) XXX amdgpu should get the same treatment. drm: put_cpu() should enable preemption, not disable it again drm(4): make pr_debug equivalent to aprint_debug significantly reduces the default spam from amdgpu(4). drm: Set CONFIG_ACPI in linux/acpi.h and make it build. Leave a little ACPI-related functionality disabled for now, like getting EDID out of ACPI -- needs a bit more work to make this work, and I don't have hardware to work on that. Should help with failures of the forms: - unable to locate a BIOS ROM - bios: unable to locate usable image on various machines. radeon_acpi.c: ifdef out unused function on NetBSD. Should fix syzkaller build. drm(4): Fix st_rdev in stat. dminor->index already has the 64*type adjustment, as allocated in drm_minor_alloc. PR kern/58180 linux_sync_file: Fix missing init/fini steps.

This is the opposite of WARN_ON. Noted by rjs@. drm_gem.c: Enable drm_gem_fence_array_add now that we emulate xa. linux_xa: Delete and replace collision in xa_store as intended.

PR xsrc/58307 x86: Teach bus_dmamem_map about BUS_DMA_PREFETCHABLE. PR port-amd64/58308 bus_dma(9): Document BUS_DMA_PREFETCHABLE. Like BUS_DMA_NOCACHE. Doesn't absolve you of the need for bus_dmamap_sync, but if you later pass the vaddr to bus_dmamap_load, the DMA map might notice the mapping is write-combining and use this to make bus_dmamap_sync cheaper. PR kern/58309 nouveau_nvkm_subdev_instmem_gk20a.c: Use BUS_DMA_PREFETCHABLE. Matches Linux's pgprot_writecombine. Unclear where the appropriate bus_dmamap_sync happens, or is supposed to happen -- not using it would be wrong, but asking for a prefetchable mapping may paper over symptoms, at least! ttm: Sync more with Linux. Add the original copyright and attribution since this is now, intentionally, a modified copy of the original and not just roughly the same algorithm. ttm: Respect PGO_ALLPAGES. Not sure this is useful but it reduces XXX's and makes this match udv_fault better so it's easier to understand. ttm: Sync cacheability flag logic with Linux. ttm: Add XXX about readahead fault failures. pci: Pass cookie through pci_find_device, pci_enumerate_bus, take 2. New functions pci_find_device1 and pci_enumerate_bus1 have the cookie argument. Existing symbols pci_find_device and pci_enumerate_bus are now wrappers for the cookieless version. This will allow pci_find_device callers to pass a cookie through to the match function so they can keep state or pass in extra parameters like b/d/f numbers, which will allow us to nix some horrible kludges in the Linux PCI API emulation for drm (and, perhaps, Intel wifi). This change drops the symbol pci_probe_device, in favour of a new pci_probe_device1 with the cookie argument. But I don't think that requires a revbump because it's only called by MD pci_enumerate_bus1 implementations, which don't live in modules anyway. Take 2: Make sure to handle NULL match function. linux_pci: Nix pci enumeration kludges. Now that we can pass a cookie through, this stuff will be a little less fragile. i915: Omit needless i915_gem_object_pin/unpin_pages cycle in fault. vm_fault_cpu and vm_fault_gtt, called by i915_gem_fault, already do the pinning and unpinning internally, so there is no need for i915_gem_fault to do it. No functional change intended, except that the transient pin count will be one lower than before during the fault routine (but it will still be positive). i915: Match Linux fault routine return code actions. Omit needless EINTR interception -- this is now handled by i915_error_to_vmf_fault. Earlier revert was over a false alarm -- bisection shows the new warnings arose from linux_pci.c 1.29 here: https://mail-index.netbsd.org/source-changes/2024/06/23/msg151929.html linux_pci: Fix shifto in pci_get_class. It looks like Linux's pci_get_class also matches the interface part of the PCI class register (but not the revision part), and I hadn't noticed that in the previous shim structured differently. With GCC12 kernel ALL/amd64 triggers "'sor' may be used uninitialized". If "sublinks & 3" is zero GCC is right and sor[1] may be returned unitialized. Fix by initializing "sor" to zero to return -1 instead of uninitialized value. Ok: Taylor R Campbell <riastradh@> amdgpu: Map BAR 2, not BAR 5, on pre-bonaire chips.

1.1.2.38	07-Mar-2014	riastradh	Make gem mmappings shared, not copy-on-write, like Linux.
1.1.2.37	05-Mar-2014	riastradh	Handle attach failure and don't try a framebuffer in i915 on failure.
1.1.2.36	04-Mar-2014	riastradh	Rework drm2 configuration and modularization. - Split drm2.kmod into drmkms_linux, drmkms, drmkms_pci. - Split up drmkms-related files.* similarly. - Make drm_agp_* routines hooks that the drmkms_pci module installs. - Reuse drm device major 180 for (old) drm and drmkms. Now old drm and new drmkms can coexist happily in the same tree, with or without PCI, and require no changes to userland.
1.1.2.35	29-Jan-2014	riastradh	First draft of in-kernel drm2 attachment. The drm2 `drm' device is now called `drmkms' (likewise `i915drmkms', &c.) so that it can coexist with the old drm code to reduce diffs from HEAD. (Can't call a device `drm2'.)
1.1.2.34	22-Jan-2014	riastradh	Little reference counting fix in drm_mmap.
1.1.2.33	22-Jan-2014	riastradh	Tidy up and reuse the code I had already written for gem mmapping.
1.1.2.32	22-Jan-2014	riastradh	Implement mmap on a drm device by a new kludgey ioctl. There is currently no way to set up a custom choice of uvm object and uvm pager ops for mmap: struct fileops has no fo_mmap, and device nodes get to say only what paddr each offset maps to, not what uvm object to use. For now, to avoid kernel changes outside the drm2 tree, we'll use a non-standard drm ioctl that calls uvm_map. This requires source patches to userland programs, but for the most part they can simply be converted from calling mmap to drmMap, which will be adapted to use the ioctl. This is not necessarily a permanent solution.
1.1.2.31	21-Jan-2014	riastradh	Call drm_mode_group_init_legacy_group in drm_attach like Linux does.
1.1.2.30	21-Jan-2014	riastradh	Adjust errno from dev->driver->load.
1.1.2.29	21-Jan-2014	riastradh	Initialize the right minor numbers...arghhhh.
1.1.2.28	21-Jan-2014	riastradh	Remove vestige of wsdisplay XXX from drm_drv.c. wsdisplay stuff happens in the parent driver now.
1.1.2.27	21-Jan-2014	riastradh	Oops -- unifdef <sys/select.h> and <sys/poll.h> in drm_drv.c.
1.1.2.26	21-Jan-2014	riastradh	Report st_rdev in stat on a drm device.
1.1.2.25	15-Jan-2014	riastradh	Hack up vblank events and make them work.
1.1.2.24	15-Jan-2014	riastradh	Fix copyoutstr usage in drm_version_string.
1.1.2.23	08-Sep-2013	riastradh	Decrement sc_opencount on drm_close.
1.1.2.22	24-Jul-2013	riastradh	Call drm_vblank_cleanup in drm_detach.
1.1.2.21	24-Jul-2013	riastradh	Initialize dev->dev, dev->primary, and dev->control in drm_attach.
1.1.2.20	24-Jul-2013	riastradh	Let drm_fill_in_dev initialize dev->driver after all.
1.1.2.19	24-Jul-2013	riastradh	Little stab at making drm_attach fail more gracefully.
1.1.2.18	24-Jul-2013	riastradh	Call dev->driver->load in drm_attach.
1.1.2.17	24-Jul-2013	riastradh	Pass drm_config_found arguments via explicit struct drm_attach_args.
1.1.2.16	24-Jul-2013	riastradh	Fill in drm_detach some more.
1.1.2.15	24-Jul-2013	riastradh	Manage an opencount for each drm device to block drm_detach.
1.1.2.14	24-Jul-2013	riastradh	Initialize sc->sc_drm_dev in drm_attach.
1.1.2.13	24-Jul-2013	riastradh	Fix up drm attachment code.
1.1.2.12	24-Jul-2013	riastradh	Implement drm_getsarea in drm_drv.c.
1.1.2.11	24-Jul-2013	riastradh	Print a warning if the drm(4) unit number is >=64.
1.1.2.10	24-Jul-2013	riastradh	Add drm_config_found for foodrm_attach to call to attach drm(4).
1.1.2.9	24-Jul-2013	riastradh	Reject drm ioctls through control minors unless explicitly allowed.
1.1.2.8	24-Jul-2013	riastradh	Rework drm minor allocation in local drm_drv.c. Need multiple different minors, of different types, for each drm device.
1.1.2.7	24-Jul-2013	riastradh	Define drm_global_mutex in local drm_drv.c.
1.1.2.6	24-Jul-2013	riastradh	Unhook drm_prime for now.
1.1.2.5	24-Jul-2013	riastradh	Fix up drm_read and drm_poll a little. Still #ifdef'd out because it needs some selnotify calls to actually work, but the #ifdef'd code now compiles and looks more plausible -- doesn't hold onto spin locks during loops and uiomoves.
1.1.2.4	24-Jul-2013	riastradh	Tag the XXX's in drm_drv.c for enhanced greppability.
1.1.2.3	24-Jul-2013	riastradh	Name fp->f_data in drm_close for clarity.
1.1.2.2	24-Jul-2013	riastradh	Move OS-independent cruft from drm_drv.c to a new drm_fops.c.
1.1.2.1	24-Jul-2013	riastradh	First draft of NetBSD drm(4) driver attachment goop. - Attachments will look like: drm0 at i915drm0 at pci0. In the future, we may have wsdisplay0 at (drmfb0 at) drm0 at pci0. The intent is to avoid having vga0, radeonfb0, &c., attach at pci0, and then having drm0 parasitically sucking their memory as we currently do with old drm. The drm0 device exists only so that we can have a unified /dev/drm device node exposed to userland (i.e., a single drm device major). - There are some OS-independent subroutines here that don't belong. I wrote them by . studying the Linux driver attachment goop in dist/drm/drm_drv.c, drm_fops.c, and drm_stub.c; . identifying what logic is about DRM rather than about Linux's driver KPI; and . writing NetBSD driver attachment goop based on that information, with the logic that is about DRM and independent of driver KPI separated out into separate subroutines (drm_open_file, &c.). - Initialization of struct drm_device is missing. It's not clear yet whether this should be done by i915drm_attach &c., perhaps using some utility (say, drm_device_initialize) defined here, or whether this should be done mostly by drm_attach. - Poll and read are missing. I suspect they will have to be filled in at some point, in spite of comments in the old drm code to the effect that they exist only for legacy X servers -- it looks like more recent libdrms rely on them. - Compile-tested only so far; this code is far from running.

(Why didn't this fail in my build?) Pass cache-related flags through to the GTT on pre-SNB devices. I had assumed for ages this would increase the amount of caching and thereby increase the chance of stale caches leading to rendering glitches. But apparently I was wrong, and failing to pass these through was causing all sorts of problems! Dedup the NetBSD portion of the code (ok Riastradh), no functional change. Don't return events that are too large and leave them in the list. Apply access control to gem mmap. fix gcc is stupid.

Taylor asked me to write up a description and then wrote most of the text below for me :-) In Linux code, we always work with ERESTARTSYS so the code meaning start over is a positive NetBSD errno safe for PTR_ERR/ERR_PTR. To achieve this: 1. adapt all cv_waits that return to Linux so they map ERESTART to ERESTARTSYS, and 2. adapt all returns to userland so they convert ERESTARTSYS to ERESTART. Leave EINTR and all other error codes alone.

1.17.8.2	29-Apr-2017	pgoyette	Revise previous. Rather than explicitly including <sys/localcount.h> in all the places where {b,c}devsw is initialized, just include it from <sys/conf.h>. This avoids an include-sequence dependancy.
1.17.8.1	29-Apr-2017	pgoyette	Add DEVSW_MODULE_INIT to existing device-driver modules, so that they willl have a localcount defined and thus be permitted to load. Without a localcount, loading the module will return EINVAL. XXX the dtrace and drm stuff might need to be fed back upstream?

1.14	02-Jul-2022	riastradh	branches: 1.14.4; drm: Rewrite drm_gem_cma_helper.h from scratch. The header file was originally part of drm with no licence text, which I took to mean BSD-licensed like the rest of the Linux drm code base is by default -- everything in Linux under include/drm and drivers/gpu/drm not otherwise marked. In 2017, a tree-wide automated change was applied to Linux which caused an SPDX GPL header to appear in drm_gem_cma_helper.h. When I asked the drm developers about this in drm files, they explained that it was an automated process and many of the SPDX headers were wrong, so when excluding GPL files in drm updates, I heeded the actual GPL vs BSD/MIT licence text and revision history rather than the SPDX headers. I excluded drm_gem_cma_helper.c because it was clearly originally GPL as an exception to the default BSD licence under Linux's drivers/gpu/drm, and Jared reimplemented the API for ues by some (NetBSD, BSD-licensed) Arm display drivers. During an update after that, the header file was lost in the merge shuffle and I copied it back in without noticing the SPDX header file. In retrospect, I see now that it's not clear what the intent was: the .c file was obviously GPL, and maybe the .h file was supposed to be too but it wasn't carved out as an exception among the drm code. To keep our story simpler, I just drafted a new .h file that provides a compatible subset of the interface we use, derived from the .c file Jared wrote, written according to several deterministic rules based on KNF that yield a non-creative specification of the compatible interface: 1. $NetBSD$ RCS id 2. standard TNF copyright statement 3. header guard derived from #include file name 4. minimal #includes, grouped and sorted according to KNF 5. forward declaration of structs, sorted lexicographically 6. definitions of structs, members sorted lexicographically by name 7. downcasting macros, written in KNF and sorted lexicographically 8. minimal extern variable declarations, sorted lexicographically 9. minimal, function prototypes, written in KNF and sorted lexicographically `Minimal' means added one by one, according to the errors issued by the compiler (and in the case of #includes, according to the correct header file for the missing types or function prototypes being used), until the compiler is formally satisfied. Any changes to this will, unless otherwise marked, be covered by the standard TNF licence now on the file.

sys/external/bsd/drm2/dist/drm/drm_gem.c: revision 1.24 sys/arch/xen/xen/xpci_xenbus.c: revision 1.29 drm: Eliminate __HAVE_ATOMIC_AS_MEMBAR conditionals. Discussed on tech-kern: https://mail-index.netbsd.org/tech-kern/2023/02/23/msg028729.html linux asm/barrier.h: Fix !MULTIPROCESSOR build. remove "nouveau" from a comment. noted by jmcneill. drm: KASSERT(A && B) -> KASSERT(A); KASSERT(B) comment a function that has a clear overbounds read but it isn't used. found by GCC 12. nix the NetBSD specific GEM_BUG_ON(). avoids GCC 12 warnings, and matches upstream closer. avoid uninitialised variable usage in drm_gem_cma_create_internal(). in the case nothing has returned 'error', 'nsegs' and the dma info are (potentially) uninitialised, so consider this an error. found by GCC 12. avoid a GCC 12 warning. there's a 1-element long array and a loop conditional that tries to see if indexes for it are not identical. as these indexes will always both be 0, the only valid index, the condition is always false. GCC 12 triggers a strange warning on this code that can never run (see below), so simply assert the array size is 1 and comment the rest. amdgpu_dc_stream.c:470:55: error: array subscript [0, 0] is outside array bounds of 'struct dc_writeback_info[1]' [-Werror=array-bounds] 470 \| stream->writeback_info[j] = stream->writeback_info[i]; convert a KASSERT() into an if () panic() sequence to appease GCC 12. OK riastradh@. drm: Fix conditionals around drmkms_pci and agp. Kernel should build now with all pci drm drivers stripped out but DRM_LEGACY still enabled. (Might not be very useful, but it'll build. Maybe we should also have DRM_LEGACY_PCI so those drivers can be modloaded later.) drmkms: Fix module build. avoid an unlikely array bounds issue picked up by GCC 12. nvkm_pcie_speed() can return -1, which is then used as an array index, so make this default return PCIe 1.0 speeds. drm: enable almost all PCIe functionality linux_pci.c revisions 1.24 and 1.25 implemented most of the remaining missing PCIe backends, but only enabled them for some amdgpu portions. this enables all code marked with "XXX amdgpu pcie", "XXX radeon pcie", and "XXX pcie speed". for most of it, simply removing #ifndefs __NetBSD__ to enable compliation was required, once the new "bus->max_bus_speed" member was added to struct pci_bus. add an "always fails" backend for pci_enable_atomic_ops_to_root() which seems to only be necessary for virtual GPU functionality (and could be implemented if needed.) tested on radeon 5450, 7750, R7 240 [radeon], and RX 550 [amdgpu], and nvidia 750 and 1030 [nouveau]. this still does not quite work on nvidia cards. there are two problems that remain: - the call to set the link speed is skipped because the speed is set to the default value of "-1". nvkm_pcie_set_link() will actually determine the right value for this and for some cards, calling this function if the current speed is -1 helps set the link speed. it may be that on linux other paths we don't have enabled properly would set this (there's one via debugfs, and a jetson specific one, though perhaps setting either AC or DC speed values as boot options (after hooking up these for netbsd) would currently work. - worse, cards newer than kepler - geforce 900, 1000, and newer, are all lacking the backing support to set pcie link speed. the GT 1030 card i have been testing with remains at pcie 1.0. radeon: fix and enable ACPI methods for getting ROM BIOS The hacky way of getting the BIOS mapped only works on x86. ACPI should be preferred if available. Makes BIOS reading though VFCT work on aarch64 with EDK2. (But only if EDK2 has POSTed the GPU.) XXX amdgpu should get the same treatment. drm: put_cpu() should enable preemption, not disable it again drm(4): make pr_debug equivalent to aprint_debug significantly reduces the default spam from amdgpu(4). drm: Set CONFIG_ACPI in linux/acpi.h and make it build. Leave a little ACPI-related functionality disabled for now, like getting EDID out of ACPI -- needs a bit more work to make this work, and I don't have hardware to work on that. Should help with failures of the forms: - unable to locate a BIOS ROM - bios: unable to locate usable image on various machines. radeon_acpi.c: ifdef out unused function on NetBSD. Should fix syzkaller build. drm(4): Fix st_rdev in stat. dminor->index already has the 64*type adjustment, as allocated in drm_minor_alloc. PR kern/58180 linux_sync_file: Fix missing init/fini steps.

Not sure this is useful but it reduces XXX's and makes this match udv_fault better so it's easier to understand. ttm: Sync cacheability flag logic with Linux. ttm: Add XXX about readahead fault failures. pci: Pass cookie through pci_find_device, pci_enumerate_bus, take 2. New functions pci_find_device1 and pci_enumerate_bus1 have the cookie argument. Existing symbols pci_find_device and pci_enumerate_bus are now wrappers for the cookieless version. This will allow pci_find_device callers to pass a cookie through to the match function so they can keep state or pass in extra parameters like b/d/f numbers, which will allow us to nix some horrible kludges in the Linux PCI API emulation for drm (and, perhaps, Intel wifi). This change drops the symbol pci_probe_device, in favour of a new pci_probe_device1 with the cookie argument. But I don't think that requires a revbump because it's only called by MD pci_enumerate_bus1 implementations, which don't live in modules anyway. Take 2: Make sure to handle NULL match function. linux_pci: Nix pci enumeration kludges. Now that we can pass a cookie through, this stuff will be a little less fragile. i915: Omit needless i915_gem_object_pin/unpin_pages cycle in fault. vm_fault_cpu and vm_fault_gtt, called by i915_gem_fault, already do the pinning and unpinning internally, so there is no need for i915_gem_fault to do it. No functional change intended, except that the transient pin count will be one lower than before during the fault routine (but it will still be positive). i915: Match Linux fault routine return code actions. Omit needless EINTR interception -- this is now handled by i915_error_to_vmf_fault. Earlier revert was over a false alarm -- bisection shows the new warnings arose from linux_pci.c 1.29 here: https://mail-index.netbsd.org/source-changes/2024/06/23/msg151929.html linux_pci: Fix shifto in pci_get_class. It looks like Linux's pci_get_class also matches the interface part of the PCI class register (but not the revision part), and I hadn't noticed that in the previous shim structured differently. With GCC12 kernel ALL/amd64 triggers "'sor' may be used uninitialized". If "sublinks & 3" is zero GCC is right and sor[1] may be returned unitialized. Fix by initializing "sor" to zero to return -1 instead of uninitialized value. Ok: Taylor R Campbell <riastradh@> amdgpu: Map BAR 2, not BAR 5, on pre-bonaire chips.

1.1.2.6	24-Jul-2013	riastradh	Add drm_limit_dma_space to limit the memory available for DMA. Designed as a compatibility stub to replace dma_set_coherent_mask in Linux. Not exactly the same, but probably close enough for all uses of dma_set_coherent_mask in Linux.
1.1.2.5	24-Jul-2013	riastradh	Fix sense of refcount decrement conditional in drm_iounmap. Add some kasserts just in case.
1.1.2.4	24-Jul-2013	riastradh	Omit __drm_pci_free. Use kmem for drm_dma_handles now that we can.
1.1.2.3	24-Jul-2013	riastradh	Update drm_memory.c to reflect drm_local_map tagged union changes.
1.1.2.2	24-Jul-2013	riastradh	Add drm_pci_alloc/drm_pci_free to local drm_memory.c. Moved here from upstream's drm_pci.c because they don't actually depend on anything of PCI; they just invoke the bus-independent bus_dma abstraction.
1.1.2.1	24-Jul-2013	riastradh	Add local drm_memory.c to implement drm_ioremap and drm_iounmap.
1.2.2.1	10-Aug-2014	tls	Rebase.

1.32	05-Sep-2023	riastradh	drm: Fix conditionals around drmkms_pci and agp. Kernel should build now with all pci drm drivers stripped out but DRM_LEGACY still enabled. (Might not be very useful, but it'll build. Maybe we should also have DRM_LEGACY_PCI so those drivers can be modloaded later.)
1.31	19-Jul-2022	riastradh	branches: 1.31.4; drm: Note dependency on sysmon_power. drm uses this for pswitch events to notify of hotplug.
1.30	17-Jul-2022	riastradh	drm: Dust off module build a little.
1.29	31-Dec-2021	riastradh	drm: Reduce default debug level to driver-specific messages. Let's make a liiiiittle less log spew by default with `boot -x'.

1.25	19-Dec-2021	riastradh	drm_global_init/release is no more
1.24	19-Dec-2021	riastradh	Remove last users of drmP.h.
1.23	19-Dec-2021	riastradh	Make ourselves less dependent on drmP.h, removed upstream. This causes some trouble as CONFIG_* lines might not be appropriately defined. A few declarations remain in drmP.h so it's not gone. Author: Maya Rashish <maya@NetBSD.org>
1.22	19-Dec-2021	riastradh	Missing includes, conditionalize on drm legacy Might want to remove drm legacy code entirely later. Author: Maya Rashish <maya@NetBSD.org>

1.19	19-Dec-2021	riastradh	Need drm_crtc_internal.h for drm_connector_ida_init/fini.
1.18	19-Dec-2021	riastradh	Include drm_internal.h by "../dist/drm/drm_internal.h".
1.17	03-Jan-2020	jmcneill	Initialize drm_bridge and drm_panel locks.
1.16	23-Sep-2019	mrg	when "boot -x", don't turn on all drm debug, just the core, driver and kms messages, eliding the vblank, atomic and prime messages, which are the truly noisy ones (and may result in impossibly slow to use systems.) XXX: pullup-all.
1.15	28-Aug-2018	riastradh	branches: 1.15.4; Rework PCI and AGP conditionalization. - Push drm_pci_set_unique into driver callback. - Eliminate drm_pci_set_unique_hook. - Gather all drm_agp_* functions into struct drm_agp_hooks. - Replace the nonsensical old atomic garbage by serious locking. - Make drm_agpsupport.c its own module. - Eliminate NDRMKMS_PCI. - Use NAGP from "agp.h" only in drm_module.c for horrible hack. => See comment in file for rationale. - Always define CONFIG_PCI=1 and CONFIG_AGP=1. - Always go through the drm_agp_* function hooks. - Ifdef out nouveau agp stuff that doesn't go through drm_agp_* for reasons that I'm too frustrated to figure out tonight. - pci_iomap no longer automagically does agp_i810_borrow. => Use drm_agp_borrow instead.
1.14	28-Aug-2018	riastradh	Move decl of drm_guarantee_initialized to drmP.h.
1.13	27-Aug-2018	riastradh	Make sure to create and destroy the lock too...
1.12	27-Aug-2018	riastradh	Make drmkms build without drmkms_pci.
1.11	13-Apr-2015	pgoyette	branches: 1.11.16; 1.11.18; Update module dependencies: drmkms does not depend on iic drmkms_linux depends on i2cexec
1.10	05-Mar-2015	riastradh	Rewrite drm_encoder_slave.c, as nouveau will need.
1.9	12-Nov-2014	christos	branches: 1.9.2; prettify and add to all the modules that have it.
1.8	14-Sep-2014	riastradh	Fix module build of drmkms.
1.7	17-Jul-2014	riastradh	branches: 1.7.2; 1.7.4; Initialize the drm_global stuff.
1.6	16-Jul-2014	riastradh	Make it build and boot on my test machines. Screen blanks on boot on the Ivy Bridge system with DRM error in cpt_serr_int_handler: PCH transcoder A FIFO underrun But after that everything is OK. Appears to be an upstream problem. To investigate... I think there's a cache flushing issue somewhere -- there are little display artefacts on my T60.
1.5	04-Apr-2014	riastradh	branches: 1.5.2; 1.5.4; 1.5.6; Figure drm_debug into the drm_init module kludgerosity.
1.4	03-Apr-2014	riastradh	Need <sys/reboot.h> for AB_DEBUG.
1.3	03-Apr-2014	riastradh	Enable drm debug output iff boothowto has AB_DEBUG set.
1.2	18-Mar-2014	riastradh	Merge riastradh-drm2 to HEAD.
1.1	24-Jul-2013	riastradh	branches: 1.1.2; file drm_module.c was initially added on branch riastradh-drm2.
1.1.2.10	04-Mar-2014	riastradh	Rework drm2 configuration and modularization. - Split drm2.kmod into drmkms_linux, drmkms, drmkms_pci. - Split up drmkms-related files.* similarly. - Make drm_agp_* routines hooks that the drmkms_pci module installs. - Reuse drm device major 180 for (old) drm and drmkms. Now old drm and new drmkms can coexist happily in the same tree, with or without PCI, and require no changes to userland.
1.1.2.9	29-Jan-2014	riastradh	First draft of in-kernel drm2 attachment. The drm2 `drm' device is now called `drmkms' (likewise `i915drmkms', &c.) so that it can coexist with the old drm code to reduce diffs from HEAD. (Can't call a device `drm2'.)
1.1.2.8	15-Jan-2014	riastradh	Clean up initialization failures in drm2_modcmd.
1.1.2.7	30-Dec-2013	riastradh	First (plausible) draft of Linux workqueue implementation rework. Untested, but this looks better than what was there before, or any of the drafts leading up to this which got torn out of the typewriter, crumpled up, and crudely tossed in frustration toward the wastepaper basket by my desk alongside the empty bottles of Jack Daniels that fueled them, or something like that. Can't use multiple CPUs per workqueue. That requires some explicit management of per-CPU workqueue state, since NetBSD's workqueue(9) doesn't provide that or cancellation or flushing. Oops.
1.1.2.6	08-Sep-2013	riastradh	Initialize and destroy drm_global_mutex on module init/fini.
1.1.2.5	24-Jul-2013	riastradh	i915_irq.c needs <linux/printk.h.
1.1.2.4	24-Jul-2013	riastradh	Implement Linux alloc_page/__free_page and kmap_atomic/kunmap_atomic.
1.1.2.3	24-Jul-2013	riastradh	Make drm2 module depend on iic, and comment on wrong dependencies.
1.1.2.2	24-Jul-2013	riastradh	Hook pci code back into drm2 module. Comment that drm_pci.c and drm_agpsupport.c should properly be put into a separate drm2pci module eventually.
1.1.2.1	24-Jul-2013	riastradh	Add drm2 module ioconf glue.
1.5.6.2	22-May-2014	yamt	sync with head. for a reference, the tree before this commit was tagged as yamt-pagecache-tag8. this commit was splitted into small chunks to avoid a limitation of cvs. ("Protocol error: too many arguments")

sys/external/bsd/drm2/dist/drm/drm_gem.c: revision 1.24 sys/arch/xen/xen/xpci_xenbus.c: revision 1.29 drm: Eliminate __HAVE_ATOMIC_AS_MEMBAR conditionals. Discussed on tech-kern: https://mail-index.netbsd.org/tech-kern/2023/02/23/msg028729.html linux asm/barrier.h: Fix !MULTIPROCESSOR build. remove "nouveau" from a comment. noted by jmcneill. drm: KASSERT(A && B) -> KASSERT(A); KASSERT(B) comment a function that has a clear overbounds read but it isn't used. found by GCC 12. nix the NetBSD specific GEM_BUG_ON(). avoids GCC 12 warnings, and matches upstream closer. avoid uninitialised variable usage in drm_gem_cma_create_internal(). in the case nothing has returned 'error', 'nsegs' and the dma info are (potentially) uninitialised, so consider this an error. found by GCC 12. avoid a GCC 12 warning. there's a 1-element long array and a loop conditional that tries to see if indexes for it are not identical. as these indexes will always both be 0, the only valid index, the condition is always false. GCC 12 triggers a strange warning on this code that can never run (see below), so simply assert the array size is 1 and comment the rest. amdgpu_dc_stream.c:470:55: error: array subscript [0, 0] is outside array bounds of 'struct dc_writeback_info[1]' [-Werror=array-bounds] 470 \| stream->writeback_info[j] = stream->writeback_info[i]; convert a KASSERT() into an if () panic() sequence to appease GCC 12. OK riastradh@. drm: Fix conditionals around drmkms_pci and agp. Kernel should build now with all pci drm drivers stripped out but DRM_LEGACY still enabled. (Might not be very useful, but it'll build. Maybe we should also have DRM_LEGACY_PCI so those drivers can be modloaded later.) drmkms: Fix module build. avoid an unlikely array bounds issue picked up by GCC 12. nvkm_pcie_speed() can return -1, which is then used as an array index, so make this default return PCIe 1.0 speeds. drm: enable almost all PCIe functionality linux_pci.c revisions 1.24 and 1.25 implemented most of the remaining missing PCIe backends, but only enabled them for some amdgpu portions. this enables all code marked with "XXX amdgpu pcie", "XXX radeon pcie", and "XXX pcie speed". for most of it, simply removing #ifndefs __NetBSD__ to enable compliation was required, once the new "bus->max_bus_speed" member was added to struct pci_bus. add an "always fails" backend for pci_enable_atomic_ops_to_root() which seems to only be necessary for virtual GPU functionality (and could be implemented if needed.) tested on radeon 5450, 7750, R7 240 [radeon], and RX 550 [amdgpu], and nvidia 750 and 1030 [nouveau]. this still does not quite work on nvidia cards. there are two problems that remain: - the call to set the link speed is skipped because the speed is set to the default value of "-1". nvkm_pcie_set_link() will actually determine the right value for this and for some cards, calling this function if the current speed is -1 helps set the link speed. it may be that on linux other paths we don't have enabled properly would set this (there's one via debugfs, and a jetson specific one, though perhaps setting either AC or DC speed values as boot options (after hooking up these for netbsd) would currently work. - worse, cards newer than kepler - geforce 900, 1000, and newer, are all lacking the backing support to set pcie link speed. the GT 1030 card i have been testing with remains at pcie 1.0. radeon: fix and enable ACPI methods for getting ROM BIOS The hacky way of getting the BIOS mapped only works on x86. ACPI should be preferred if available. Makes BIOS reading though VFCT work on aarch64 with EDK2. (But only if EDK2 has POSTed the GPU.) XXX amdgpu should get the same treatment. drm: put_cpu() should enable preemption, not disable it again drm(4): make pr_debug equivalent to aprint_debug significantly reduces the default spam from amdgpu(4). drm: Set CONFIG_ACPI in linux/acpi.h and make it build. Leave a little ACPI-related functionality disabled for now, like getting EDID out of ACPI -- needs a bit more work to make this work, and I don't have hardware to work on that. Should help with failures of the forms: - unable to locate a BIOS ROM - bios: unable to locate usable image on various machines. radeon_acpi.c: ifdef out unused function on NetBSD. Should fix syzkaller build. drm(4): Fix st_rdev in stat. dminor->index already has the 64*type adjustment, as allocated in drm_minor_alloc. PR kern/58180 linux_sync_file: Fix missing init/fini steps.

New functions pci_find_device1 and pci_enumerate_bus1 have the cookie argument. Existing symbols pci_find_device and pci_enumerate_bus are now wrappers for the cookieless version. This will allow pci_find_device callers to pass a cookie through to the match function so they can keep state or pass in extra parameters like b/d/f numbers, which will allow us to nix some horrible kludges in the Linux PCI API emulation for drm (and, perhaps, Intel wifi). This change drops the symbol pci_probe_device, in favour of a new pci_probe_device1 with the cookie argument. But I don't think that requires a revbump because it's only called by MD pci_enumerate_bus1 implementations, which don't live in modules anyway. Take 2: Make sure to handle NULL match function. linux_pci: Nix pci enumeration kludges. Now that we can pass a cookie through, this stuff will be a little less fragile. i915: Omit needless i915_gem_object_pin/unpin_pages cycle in fault. vm_fault_cpu and vm_fault_gtt, called by i915_gem_fault, already do the pinning and unpinning internally, so there is no need for i915_gem_fault to do it. No functional change intended, except that the transient pin count will be one lower than before during the fault routine (but it will still be positive). i915: Match Linux fault routine return code actions. Omit needless EINTR interception -- this is now handled by i915_error_to_vmf_fault. Earlier revert was over a false alarm -- bisection shows the new warnings arose from linux_pci.c 1.29 here: https://mail-index.netbsd.org/source-changes/2024/06/23/msg151929.html linux_pci: Fix shifto in pci_get_class. It looks like Linux's pci_get_class also matches the interface part of the PCI class register (but not the revision part), and I hadn't noticed that in the previous shim structured differently. With GCC12 kernel ALL/amd64 triggers "'sor' may be used uninitialized". If "sublinks & 3" is zero GCC is right and sor[1] may be returned unitialized. Fix by initializing "sor" to zero to return -1 instead of uninitialized value. Ok: Taylor R Campbell <riastradh@> amdgpu: Map BAR 2, not BAR 5, on pre-bonaire chips. PR kern/58384 amdgpu: Map consecutive pages, not the same one over and over again. PR kern/58385 linux/bitops: Fix overestimate for BITS_TO_LONGS(9) Fortunately, this seems harmless except for allocating excessive buffer memory. Pointed out by nonaka@, OK riastradh@.

If the pipe is disabled but some SDVO outputs are active, we may end up dividing by zero in intel_sdvo_get_config(). Fixes https://bugs.freedesktop.org/show_bug.cgi?id=3D76520 Tweak slightly sketchy logic in linux_idr. 1. idr_preload can fail if you don't set __GFP_WAIT. 2. If idr_preload fails, it is wrong for idr_alloc to assert. 3. There is no way for idr_alloc to know what flags idr_preload got. Probably won't fix any bugs, but if there is a bug with a missing __GFP_WAIT, then we will learn about a trifle sooner. Fix error branch in ttm_dma_tt_init to avoid double-free. Should fix symptom of PR kern/52438, but who knows what underlying problem causes us to reach the error branch in the first place. Fix lockdebug_locked annotations. When thread A grants ownership to thread B waiting with a context, thread B needs to assert lockdebug_locked; otherwise, when it releases, lockdebug_unlocked thinks it's releasing an unlocked ww_mutex. Fixes LOCKDEBUG failure with radeon noticed by martin@. more const XXX: add a NULL init to avoid a GCC 6 maybe uninit warning. Remove UB from definition of symbols in i915_reg.h Kernel Undefined Behavior Sanitizer enforces more warnings in build time. This makes the build fatal in the drm/i915 code in: - intel_ddi_put_crtc_pll(), - intel_ddi_clock_get(), - intel_ddi_pll_enable(), - intel_ddi_setup_hw_pll_state(). The error message in all the cases says: error: case label does not reduce to an integer constant Set the type of the value left shifted to unsigned. This change is required to build NetBSD/amd64 with KUBSan.

1.13	06-Jul-2022	riastradh	uvm(9): fo_mmap caller guarantees positive size. No functional change intended, just sprinkling assertions to make it clearer.
1.12	19-Dec-2021	riastradh	Use drmP.h less in our local files. Author: Maya Rashish <maya@NetBSD.org>
1.11	14-Feb-2020	riastradh	Reduce diffs by nixing DRM_SUSER macro, deleted upstream long ago. Instead stub Linux capable(CAP_SYS_ADMIN).
1.10	27-Aug-2018	riastradh	branches: 1.10.6; Need <uvm/uvm.h> for struct uvm_object.
1.9	27-Aug-2018	riastradh	Rename drm_mmap_* -> drm_legacy_mmap_* like upstream.
1.8	27-Aug-2018	riastradh	Get the legacy drm declarations from drm_legacy.h.
1.7	31-Dec-2014	mrg	branches: 1.7.16; 1.7.18; fix a confusion between dev_t and devmajor_t, and include the primary minor when calling makedev().
1.6	14-Dec-2014	chs	add a new "fo_mmap" fileops method to allow use of arbitrary uvm_objects for mappings of file objects. move vnode-specific details of mmap()ing a vnode from uvm_mmap() to the new vnode-specific vn_mmap(). add new uvm_mmap_dev() and uvm_mmap_anon() convenience functions for mapping character devices and anonymous memory, and replace all other calls to uvm_mmap() with those. use the new fileop in drm2 so that libdrm can use mmap() to map things like on other platforms (instead of the ioctl that we have used so far).
1.5	26-Jul-2014	riastradh	branches: 1.5.2; 1.5.4; 1.5.6; Let the drm driver decide what part of what object gets mmapped. Pass the file around too so radeon/ttm can get at it to verify access. Add drm_gem_or_legacy_mmap_object for drivers to choose the previous behaviour, like i915.
1.4	16-Jul-2014	riastradh	Make it build and boot on my test machines. Screen blanks on boot on the Ivy Bridge system with DRM error in cpt_serr_int_handler: PCH transcoder A FIFO underrun But after that everything is OK. Appears to be an upstream problem. To investigate... I think there's a cache flushing issue somewhere -- there are little display artefacts on my T60.
1.3	01-May-2014	riastradh	branches: 1.3.2; 1.3.4; Tweak some DRM GEM page indexing crap. - Fix order of subtraction in drm_mmap_paddr_locked. - Address GEM objects' pages from 0, not from the mmap cookie. - Check page alignment earlier in mmap code paths. - Sprinkle kasserts throughout. Still doesn't fix the garbage that is sometimes being scribbled all over kernel memory!
1.2	18-Mar-2014	riastradh	branches: 1.2.2; Merge riastradh-drm2 to HEAD.
1.1	24-Jul-2013	riastradh	branches: 1.1.2; file drm_vm.c was initially added on branch riastradh-drm2.
1.1.2.6	04-Mar-2014	riastradh	Rework drm2 configuration and modularization. - Split drm2.kmod into drmkms_linux, drmkms, drmkms_pci. - Split up drmkms-related files.* similarly. - Make drm_agp_* routines hooks that the drmkms_pci module installs. - Reuse drm device major 180 for (old) drm and drmkms. Now old drm and new drmkms can coexist happily in the same tree, with or without PCI, and require no changes to userland.
1.1.2.5	29-Jan-2014	riastradh	First draft of in-kernel drm2 attachment. The drm2 `drm' device is now called `drmkms' (likewise `i915drmkms', &c.) so that it can coexist with the old drm code to reduce diffs from HEAD. (Can't call a device `drm2'.)
1.1.2.4	22-Jan-2014	riastradh	Tidy up and reuse the code I had already written for gem mmapping.
1.1.2.3	22-Jan-2014	riastradh	Implement mmap on a drm device by a new kludgey ioctl. There is currently no way to set up a custom choice of uvm object and uvm pager ops for mmap: struct fileops has no fo_mmap, and device nodes get to say only what paddr each offset maps to, not what uvm object to use. For now, to avoid kernel changes outside the drm2 tree, we'll use a non-standard drm ioctl that calls uvm_map. This requires source patches to userland programs, but for the most part they can simply be converted from calling mmap to drmMap, which will be adapted to use the ioctl. This is not necessarily a permanent solution.
1.1.2.2	08-Sep-2013	riastradh	Avoid the PAGE_MASK mess in drm_gem_vm.c, drm_scatter.c, & drm_vm.c.
1.1.2.1	24-Jul-2013	riastradh	Add local drm_vm.c with uvm-style (but non-gem) drm page mapping.
1.2.2.1	10-Aug-2014	tls	Rebase.

If related to PR kern/51076, might help catch the bug a bit earlier. - revert rev 1.6. we don't have access to those files as normal files and possible will get them directly elsewhere soon.

CID 989067. - Rework ttm tt swapin/swapout logic. Rather than handling `swapping in/out' here, per se, we let uvm do that, we interpret `swap out' as `deactivate pages', and we add generic ttm operations to wire and unwire pages, for the ttm_tt driver to use. This fixes certain graphics buffer eviction logic, which enables nouveau to suspend/resume on one of my machines. (The machine doesn't resume overall for other reasons, but the nouveau device suspends and resumes in isolation.) - Use bus_space_subregion to get fifo channels out of mmio registers. Evidently it is not enough to just map them separately. Ran out of time to investigate why, last time I poked at this and confirmed this change works. - Avoid taking locks during interrupts and explain why we are doing it this way. - We now use cpu_intr_p() all the time.

1.16	01-Sep-2022	riastradh	drmfb: Rework console detection and takeover. While here, simplify logic by removing an unreachable error branch so we never have to contemplate unwinding claiming of the console.
1.15	01-Sep-2022	riastradh	drmfb: Take is_console property from parent, not from self. The parent is the pci or platform device that firmware knows about. The `drmfb' device is more of a fictitious invention of the drm stack that exists for the convenience of the genfb abstraction which needs device_private to be a struct genfb_softc. Let's see if this does any better than the last attempt to rework the logic here.

1.13	16-Feb-2022	riastradh	drm: Respect is_console property on main drm device, not fb child. The MD device enumeration sets the property on, e.g., PCI devices -- not on drm framebuffer children, which are mostly a software abstraction. Not sure examining the nouveaufb, intelfb, &c., device properties is worthwhile at all, but in case it breaks something let's just leave it in while we're fixing other things.

1.83	28-Jul-2022	riastradh	drm: New option DRM_LEGACY. This brings in the `drmums' components, which are the parts of the current drm code base (sys/external/bsd/drm2) needed by legacy user-mode-setting drivers (currently just viadrmums), in contrast to the old drm code base (sys/external/bsd/drm). This way, viadrmums.kmod can be loaded into GENERIC i386 kernels, but platforms without any relevant legacy UMS drivers don't get the legacy goo statically baked in.
1.82	28-Jul-2022	riastradh	drmkms_sched: Remove duplicate module definition.
1.81	24-Jul-2022	riastradh	drm: Fix CPPFLAGS for drm scheduler code.
1.80	23-Jul-2022	riastradh	drm: Split scheduler into separate module. Used only by amdgpu, and it uses something that is currently broken from the gcc update on aarch64, so let's make it a little more optional.
1.79	20-Jul-2022	riastradh	drm: Keep drm include flags in CPPFLAGS.drmkms after all. Failures from this are much more obvious to debug than files with missing #ifdefs, which sometimes lead to build failures but could also just lead to silent miscompilation.
1.78	20-Jul-2022	riastradh	drm: Restore pollution of CPPFLAGS with include directories. Too much trouble to make this fine-grained.
1.77	19-Jul-2022	riastradh	drm: Undefine `alpha' in CPPFLAGS. Causes lotsa trouble! But don't undefine it outside drmkms; `#ifdef alpha' or equivalent is used elsewhere in-tree. (Maybe it should be replaced by __alpha__.)
1.76	19-Jul-2022	riastradh	drm: Narrow scope of drm CPPLAGS just to drm files. No need for various Linux compat definitions elsewhere in the kernel.
1.75	19-Jul-2022	riastradh	drm: Propagate CPPFLAGS.drmkms into all the drm drivers.
1.74	19-Jul-2022	riastradh	drm: Note dependency on sysmon_power. drm uses this for pswitch events to notify of hotplug.
1.73	22-May-2022	tnn	rename CONFIG_AARCH64 to CONFIG_ARM64 which is what upstream code expects
1.72	21-Dec-2021	tnn	drm: sprinkle some -Wno-unused-function for clang 915_sw_fence.c: for debug_fence_init_onstack drm_mm.c: for rb_hole_size_to_node intel_hdmi.c: for intel_hdmi_hdcp2_protocol intel_guc_submission.c: for rq_prio nouveau_nvkm_subdev_instmem_base.c: for fake_ioread32_native nouveau_nvkm_subdev_mmu_vmmnv04.c: for nv04_vmm_pgt_pte
1.71	19-Dec-2021	riastradh	drm: Make scheduler mandatory to make amdgpu module simpler.
1.70	19-Dec-2021	riastradh	drm: Make some legacy UMS crap build.
1.69	19-Dec-2021	riastradh	amdgpu: Stub out irq domain stuff with a finer grain.
1.68	19-Dec-2021	riastradh	drm: Place drm_hdcp.c like other overrides in files.drmkms.
1.67	19-Dec-2021	riastradh	drm: Stub out drm_hdcp.c
1.66	19-Dec-2021	riastradh	drm: Remove local diffs for drm_pci_set_busid. Instead, move it to its own file that can be safely used without bringing in a link/run-time dependency on pci.
1.65	19-Dec-2021	riastradh	Get drm_mm.c building. Just replace the interval tree lookup by a linear search for now.
1.64	19-Dec-2021	riastradh	Revert part of previous: no separate CPPFLAGS.drmkms. There are too many drms users outside sys/external/bsd/drm2 for now; will hold off on this until we find a better way to keep the drm includes modularized.
1.63	19-Dec-2021	riastradh	Narrow the CPPFLAGS for drm subsystems. No need for the whole kernel to be built with -I flags for the drm header files.
1.62	19-Dec-2021	riastradh	drm_client stubs
1.61	19-Dec-2021	riastradh	Regen and remerge.
1.60	19-Dec-2021	riastradh	drm_writeback stubs
1.59	19-Dec-2021	riastradh	Eliminate drm_file.c copypasta.
1.58	19-Dec-2021	riastradh	Rerun drm2netbsd and merge. New tag drmums for the legacy stuff; to deal with later for via.
1.57	19-Dec-2021	riastradh	Empty out drm_os_netbsd.h.
1.56	19-Dec-2021	riastradh	Disable missing files for now.
1.55	19-Dec-2021	riastradh	Merge updated drm2netbsd output.
1.54	19-Dec-2021	riastradh	Remove these two files from the list. We have our own copies of the same name. Since we don't support building two files with the same name, it's pretty clear the intention was to build just our copy of the file. Author: Maya Rashish <maya@NetBSD.org>
1.53	19-Dec-2021	riastradh	upstream shadows, disable warning Author: Maya Rashish <maya@NetBSD.org>
1.52	19-Dec-2021	riastradh	We have local versions of these files, don't use upstream ones Author: Maya Rashish <maya@NetBSD.org>
1.51	19-Dec-2021	riastradh	Upstream uses shadowing, disable warning Author: Maya Rashish <maya@NetBSD.org>
1.50	19-Dec-2021	riastradh	Disable warnings about shadowing. Upstream does shadowing here, I'm feeling uncomfortable changing their code. Author: Maya Rashish <maya@NetBSD.org>
1.49	19-Dec-2021	riastradh	skip upstream drm_cache.c, we have our own Author: Maya Rashish <maya@NetBSD.org>
1.48	19-Dec-2021	riastradh	Remove duplicates and non-existent files. Author: Maya Rashish <maya@NetBSD.org>
1.47	19-Dec-2021	riastradh	misc drm hacks
1.46	19-Dec-2021	riastradh	Unhook drm_kms_helper_common.c from build.
1.45	19-Dec-2021	riastradh	Define CONFIG_DRM_FBDEV_OVERALLOC=100 to match upstream.
1.44	19-Dec-2021	riastradh	Rename drm_fops.c -> drm_file.c
1.43	19-Dec-2021	riastradh	Use -Wno-missing-field-initializers for drm to reduce diffs.
1.42	19-Dec-2021	riastradh	Move IS_REACHABLE to <linux/kernel.h> to avoid double definition.
1.41	19-Dec-2021	riastradh	Define IS_ENABLED and IS_REACHABLE on the command line. Header file is too late for it, apparently. XXX Find a way to put this into a header file; command-line -D arguments are ugly.
1.40	19-Dec-2021	riastradh	No more hacks for dist/uapi -- got moved to dist/include/uapi.
1.39	19-Dec-2021	riastradh	Disable _trace_points.c. I accidentally deleted these in the import, because the _trace.h files got in the way and I forgot the _trace_points.c files were fine. There's nothing important in them anyway, so nothing of value is lost. Maybe next time I will remember to delete the _trace.h files on import but not the *_trace_points.c to reduce diffs, but that's too much trouble at this point.
1.38	19-Dec-2021	riastradh	Unfinished local implementation of GPL drm_lease.c.
1.37	19-Dec-2021	riastradh	Local reimplementation of GPL drm_gem_framebuffer_helper.c.
1.36	19-Dec-2021	riastradh	Generate files.* using the 2netbsd scripts. Author: Maya Rashish <maya@NetBSD.org>
1.35	02-Jun-2021	nia	drm2: build with -fwrapv, since the Linux kernel does and we don't want to spend too much time fixing their code. silences a lot of KUBSAN warnings. we need to use COPTS to have per-option compiler flags. help from Riastradh.
1.34	14-Feb-2020	riastradh	branches: 1.34.10; 1.34.14; Eliminate -Wpointer-arith patches; use -Wno-pointer-arith instead.
1.33	09-Dec-2019	jakllsch	branches: 1.33.2; build drm_panel.c w/ drmkms
1.32	18-Nov-2019	christos	don't build stub if legacy drm is present too.
1.31	16-Nov-2019	christos	Add a stub for drm_ioctl() so that compat32 links with kernels without drmkms.
1.30	28-Aug-2018	riastradh	branches: 1.30.4; Rework PCI and AGP conditionalization. - Push drm_pci_set_unique into driver callback. - Eliminate drm_pci_set_unique_hook. - Gather all drm_agp_* functions into struct drm_agp_hooks. - Replace the nonsensical old atomic garbage by serious locking. - Make drm_agpsupport.c its own module. - Eliminate NDRMKMS_PCI. - Use NAGP from "agp.h" only in drm_module.c for horrible hack. => See comment in file for rationale. - Always define CONFIG_PCI=1 and CONFIG_AGP=1. - Always go through the drm_agp_* function hooks. - Ifdef out nouveau agp stuff that doesn't go through drm_agp_* for reasons that I'm too frustrated to figure out tonight. - pci_iomap no longer automagically does agp_i810_borrow. => Use drm_agp_borrow instead.
1.29	27-Aug-2018	riastradh	Unhook upstream drm_pci.c, apparently overridden by files.drmkms_pci.
1.28	27-Aug-2018	riastradh	Draft support for drm prime.
1.27	27-Aug-2018	riastradh	Define CONFIG_DRM_FBDEV_EMULATION=1 in generic drmkms code. This was accidentally pulled in by i915drmkms, but we need it generically or else we need to patch upstream differently.
1.26	27-Aug-2018	riastradh	Sort. Put CWARNFLAGS next to source lists.
1.25	27-Aug-2018	riastradh	drm_fb_helper.c got lost in the merge, restore it.
1.24	27-Aug-2018	riastradh	Move drm_ioctl to drm_ioctl.c. Previously it was in drm_drv.c upstream, which we overrode; then it got moved to drm_ioctl.c and drm_drv.c got deleted, so we no longer need to maintain a separate copy of the table in what we now call drm_cdevsw.c.
1.23	27-Aug-2018	riastradh	Patch up drm_atomic_helper.c. - Mark unused variables as such. . Mistakes in local patches are likely to lead to unused variables, so keep this warning enabled. - Build with -Wno-shadow. . Local patches aren't likely to cause this, so just suppress it. - static plane_crtc_active
1.22	27-Aug-2018	riastradh	We have a local override for drm_encoder_slave.c.
1.21	27-Aug-2018	riastradh	Reorder header files to avoid drm_legacy.h lossage.
1.20	27-Aug-2018	riastradh	Restore more locally overridden files.
1.19	27-Aug-2018	riastradh	Rename drm_drv.c to drm_cdevsw.c. Previously we overrode upstream's drm_drv.c altogether, and used upstream's drm_stub.c subroutines. But upstream deleted drm_drv.c and renamed drm_stub.c to drm_drv.c, so we have to cope with that reshuffle.
1.18	27-Aug-2018	riastradh	Apply locally overridden files.
1.17	27-Aug-2018	riastradh	Omit PCI files from files.drmkms.
1.16	27-Aug-2018	riastradh	regen files.drmkms
1.15	27-Aug-2018	riastradh	Move local files to the top to make them more visible.
1.14	26-Dec-2017	jmcneill	branches: 1.14.2; 1.14.4; Implement the DRM GEM/CMA helpers. The implementation has been extracted from our tegra DRM driver, but generalized for use with other drivers.
1.13	24-Feb-2016	skrll	Move linux_work.c and workqueue.h from sys/external/bsd/drm2 to sys/external/common so that they can be used by others. LGTM from riastradh@ These should really live outside sys/external, but that can be decided later
1.12	20-Aug-2015	skrll	Tweak IS_ENABLED to allow CONFIG_FOO values. No functional change to drm2. LGTM from riastradh@
1.11	05-Mar-2015	riastradh	Factor generic parts of intelfb out into a drmfb. Adapting radeondrmkmsfb should not be hard. This will make nouveaufb easier too.
1.10	05-Mar-2015	riastradh	Rewrite drm_encoder_slave.c, as nouveau will need.
1.9	12-Nov-2014	christos	branches: 1.9.2; Add __link_set based code to automatically convert the linux module parameters into sysctls.
1.8	14-Sep-2014	riastradh	Split drm ttm config into a separate file.
1.7	16-Jul-2014	riastradh	branches: 1.7.2; 1.7.4; First whack at radeon driver. No hardware to test yet, but it builds.
1.6	16-Jul-2014	riastradh	Make it build and boot on my test machines. Screen blanks on boot on the Ivy Bridge system with DRM error in cpt_serr_int_handler: PCH transcoder A FIFO underrun But after that everything is OK. Appears to be an upstream problem. To investigate... I think there's a cache flushing issue somewhere -- there are little display artefacts on my T60.
1.5	01-Apr-2014	riastradh	branches: 1.5.2; 1.5.4; 1.5.6; Make drmkms find header files from sys/external/bsd/common.
1.4	31-Mar-2014	riastradh	Move the drmkms i2c dependencies to where they belong.
1.3	27-Mar-2014	christos	add missing dependencies (Takahiro HAYASHI)
1.2	18-Mar-2014	riastradh	Merge riastradh-drm2 to HEAD.
1.1	04-Mar-2014	riastradh	branches: 1.1.2; file files.drmkms was initially added on branch riastradh-drm2.
1.1.2.1	04-Mar-2014	riastradh	Rework drm2 configuration and modularization. - Split drm2.kmod into drmkms_linux, drmkms, drmkms_pci. - Split up drmkms-related files.* similarly. - Make drm_agp_* routines hooks that the drmkms_pci module installs. - Reuse drm device major 180 for (old) drm and drmkms. Now old drm and new drmkms can coexist happily in the same tree, with or without PCI, and require no changes to userland.
1.5.6.2	22-May-2014	yamt	sync with head. for a reference, the tree before this commit was tagged as yamt-pagecache-tag8. this commit was splitted into small chunks to avoid a limitation of cvs. ("Protocol error: too many arguments")

KERNHIST based debug - FS/LS isoc support on ehci(4). - conversion to kmem(9) - Some USB 3 support - mostly from Takahiro HAYASHI (t-hash). - interrupt transfers now get proper DMA operations - general bug fixes - kern/48308 - uhub status notification improvements - umass(4) probe fix (applied to HEAD already) - ohci(4) short transfer fix - Change the SOFTINT level from NET to SERIAL for the USB softint handler. This gives the callback a chance of running when another softint handler at SOFTINT_NET has blocked holding a lock, e.g. softnet_lock and most of the network stack. - kern/49065 - ifconfig tun0 ... sequence locks up system / lockup: softnet_lock held across usb xfr - kern/50491 - unkillable wait in usbd_transfer while using usmsc0 on raspberry pi 2 - kern/51395 - USB Ethernet makes xhci hang - Various improvements to slhci(4) - Various improvements to dwc2(4)
