Revision	Date	Author	Comments
1.43	09-Jul-2022	riastradh	linux/hdmi.h: Split out logic into .c file. Shoulda done this ages ago.
1.42	27-Feb-2022	jakllsch	only build linux_acpi.c if we have acpi(4) in the kernel
1.41	27-Feb-2022	riastradh	drm: Move acpi_check_dsm &c. from intel_acpi.c to new linux_acpi.c.
1.40	19-Dec-2021	riastradh	drm: Move io_mapping to very own .c file.
1.39	19-Dec-2021	riastradh	drm: linux kthread stubs
1.38	19-Dec-2021	riastradh	linux: Rename linux_sg.c -> linux_sgt.c. Avoids collision with compat_linux.
1.37	19-Dec-2021	riastradh	linux: Kludgey radix tree shims
1.36	19-Dec-2021	riastradh	linux: Draft half-arsed xarray shims
1.35	19-Dec-2021	riastradh	linux: dma fence array stubs
1.34	19-Dec-2021	riastradh	linux: Draft irq_work shims, in terms of a softint. Doesn't actually run in hardirq context, but who's gonna notice...
1.33	19-Dec-2021	riastradh	i915: more work
1.32	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.
1.31	19-Dec-2021	riastradh	linux compat: Draft hrtimer shims. (not actually high-resolution, just a wrapper around callout(9))
1.30	19-Dec-2021	riastradh	linux: Draft rwsem with bodgy semantics.
1.29	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.
1.28	19-Dec-2021	riastradh	Move Linux firmware shims to their own .c file.
1.27	19-Dec-2021	riastradh	dma fence chain stubs
1.26	19-Dec-2021	riastradh	backlight stubs
1.25	19-Dec-2021	riastradh	Draft sync_file.
1.24	19-Dec-2021	riastradh	Rename reservation_object -> dma_resv.
1.23	19-Dec-2021	riastradh	Move Linux SRCU to common.
1.22	19-Dec-2021	riastradh	Draft stop_machine. Hope the callback runs quickly under splhigh...
1.21	19-Dec-2021	riastradh	Move Linux RCU to common.
1.20	19-Dec-2021	riastradh	linux/wait_bit.h
1.19	19-Dec-2021	riastradh	Draft SRCU implementation.
1.18	19-Dec-2021	riastradh	Rename fence -> dma_fence, step 2: files files.
1.17	27-Aug-2018	riastradh	Draft support for drm prime.
1.16	27-Aug-2018	riastradh	Hash-locked atomic64 to give ports like powerpc32 a chance at radeon.
1.15	27-Aug-2018	riastradh	Move the Linux PCI shim into its very own .c file. The poor thing has deserved this for a very long time, even though it is full of kludges. Also I'm tired of recompiling everything every time I touch it.
1.14	27-Aug-2018	riastradh	Sort.
1.13	27-Aug-2018	riastradh	Draft implementation of the Linux reservation and fence APIs.
1.12	27-Aug-2018	riastradh	Implement some of the Linux RCU API.
1.11	27-Aug-2018	riastradh	Sort in the standard English alphabetical order, please.
1.10	27-Aug-2018	riastradh	Sort.
1.9	24-Feb-2016	skrll	branches: 1.9.16; 1.9.18; 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
1.8	08-Jan-2015	riastradh	Move Linux ww_mutex code into a .c file where it belongs.
1.7	17-Jul-2014	riastradh	branches: 1.7.2; 1.7.4; 1.7.6; Remove needless linux_gfp.c. Trying to make do with Linux's page allocation interface is pretty much always wrong: either we let uvm allocate pages in uvm objects for us, or we use bus_dma.
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	25-Apr-2014	riastradh	branches: 1.5.2; 1.5.4; Implement Linux dmi_check_system API. Use it to get a Thinkpad quirk for i915 graphics. Patch from nonoka@, PR 48708.
1.4	01-Apr-2014	riastradh	branches: 1.4.2; Make drmkms find header files from sys/external/bsd/common.
1.3	31-Mar-2014	riastradh	Move the drmkms i2c dependencies to where they belong.
1.2	18-Mar-2014	riastradh	Merge riastradh-drm2 to HEAD.
1.1	04-Mar-2014	riastradh	branches: 1.1.2; file files.drmkms_linux 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.
1.4.2.1	10-Aug-2014	tls	Rebase.
1.5.4.2	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")

netbsd-7-nhusb Merge netbsd-7-nhusb: - API / infrastructure changes to support memory management changes. - Memory management improvements and bug fixes. - HCDs should now be MP safe - conversion to 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)

1.2	27-Aug-2018	riastradh	Fix argument types of atomic64_add/sub to be sensible. Technically Linux does use long long rather than int64_t, but that's silly.
1.1	27-Aug-2018	riastradh	Hash-locked atomic64 to give ports like powerpc32 a chance at radeon.

1.1	19-Dec-2021	riastradh	backlight stubs
1.17	20-May-2024	riastradh	drm: Fix missing bounds checks in dma buf mmap.

1.15	09-Apr-2022	riastradh	branches: 1.15.4; drm: Convert membar_enter/exit stragglers to membar_acquire/release.
1.14	17-Feb-2022	riastradh	drm: Fix membars around dma_buf_put reference count release.
1.13	19-Dec-2021	riastradh	amdgpu: amdgpu_dma_buf.c
1.12	19-Dec-2021	riastradh	drm: Omit half-baked dma_buf_file indirection.
1.11	19-Dec-2021	riastradh	drm: Note NetBSD->Linux errno conversion.
1.10	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.
1.9	19-Dec-2021	riastradh	Rename reservation_object -> dma_resv.
1.8	19-Dec-2021	riastradh	Update dma-buf API enough to compile drm_prime.c.
1.7	19-Dec-2021	riastradh	No need for <linux/fence.h> in linux_dma_buf.c.
1.6	17-Oct-2019	maya	correct error handling. from Ilja Van Sprundel, thanks.

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.

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.

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.

1.8	27-Aug-2018	riastradh	Linux fence_put accepts NULL as noop. Match this. From mrg@.

1.4	27-Aug-2018	riastradh	Fix prototype of function in comment.
1.3	27-Aug-2018	riastradh	Fence release callback may be absent; default to fence_free.
1.2	27-Aug-2018	riastradh	Use atomics to manage fence->flags. Outside users use this field too, and expect it to be managed with atomics.

1.1	19-Dec-2021	riastradh	Move Linux firmware shims to their own .c file.
1.3	17-Jul-2014	riastradh	Remove needless linux_gfp.c. Trying to make do with Linux's page allocation interface is pretty much always wrong: either we let uvm allocate pages in uvm objects for us, or we use bus_dma.

1.4	09-Jul-2022	riastradh	linux/hdmi: Zero entire union hdmi_infoframe on unpack. Don't just zero the part that we're about to initialize -- i915 does memcmp on the whole structure.

1.3	19-Dec-2021	riastradh	drm: Eliminate hrtimer_destroy and teardown_timer. These are non-Linux shims added to the Linux API to pair with hrtimer_setup and setup_timer, but they really only serve to call callout_destroy, which is not strictly necessary in the NetBSD API. So although we lose a little bit of diagnostic help this way, we also reduce diffs a bit and save some trouble that bit us last week.

1.7	22-May-2022	riastradh	linux: Repeat i2c transfer if driver fails with EAGAIN. The Intel GMBUS (graphics management bus, i2c controller) relies on this now to fall back from interrupt-driven xfers to bit-banging.
1.6	19-Dec-2021	riastradh	Make intel_psr.c build netbsd-ify Stub out intel_lpe_audio.c (for now?). Hammer intel_opregion.c into shape.

1.15	19-Dec-2021	riastradh	linux/idr: Remove meaningless stray membar.
1.14	19-Dec-2021	riastradh	Teach idr_remove to accept failure. But teach it to return the data if it succeeds too.
1.13	19-Dec-2021	riastradh	Define idr_init_base. Nothing actually uses this at the moment, because callers already specify the base. Not really sure what the point is!
1.12	27-Aug-2018	riastradh	sdt probe naming style.
1.11	27-Aug-2018	riastradh	Work around broken empty expansion of SDT_PROBE* if !KDTRACE_HOOKS.
1.10	27-Aug-2018	riastradh	sdt dtrace probes for linux idr.
1.9	27-Aug-2018	riastradh	Zero-initialize idr cache.
1.8	27-Aug-2018	riastradh	Draft rewrite of idr preload. Previous idr code assumed every caller would definitely call idr_preload, idr_alloc, idr_preload_end, but some callers skip idr_alloc if an intermediate failure happens first, and would therefore leak idr nodes. Use a per-lwp single-node cache instead, and print warnings about leakers.
1.7	27-Aug-2018	riastradh	Add idr_get_next and idr_for_each_entry.
1.6	26-Jul-2017	riastradh	branches: 1.6.2; 1.6.4; 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.
1.5	01-Jan-2015	mrg	branches: 1.5.10; due to hangs seen by several folks, for now revert: http://mail-index.netbsd.org/source-changes/2014/11/04/msg060120.html Log Message: This code should be MP-safe. Use IPL_SCHED in place of IPL_DRM/IPL_VM and set D_MPSAFE flag in cdevsw.

1.3	16-Jul-2014	riastradh	branches: 1.3.4; 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.
1.1	24-Jul-2013	riastradh	branches: 1.1.2; file linux_idr.c was initially added on branch riastradh-drm2.
1.1.2.12	15-Jan-2014	riastradh	Convert linux_idr(9) to use spin locks. idr_for_each is unlocked; caller must exclude modifications. Eventually this should be rewritten with pserialize and a fancy bitmap algorithm, but this actually works for now.
1.1.2.11	15-Jan-2014	riastradh	Revert "Rewrite idr to use a dumber algorithm that admits pserialized use." This reverts commit 3a389a1cb20777fb73575f0514b96265052ac1ea. I don't know what I was smoking with this; just need to change the rwlock to a spin lock and we'll be good!
1.1.2.10	30-Dec-2013	riastradh	Rewrite idr to use a dumber algorithm that admits pserialized use. drm2 doesn't use them with RCU, but it does use them under spin locks, so an rwlock is not kosher. This algorithm is super-dumb, but the idr API has changed upstream, and this is not performance-critical, so it's not worth investing time in a better algorithm at the moment.
1.1.2.9	24-Jul-2013	riastradh	Rework error branches of idr_get_new_above. Return ENOSPC if we're about to overflow int.
1.1.2.8	24-Jul-2013	riastradh	Actually return the new id in idr_get_new_above.
1.1.2.7	24-Jul-2013	riastradh	Work around rb_tree_iterate API botch in linux_idr.c.
1.1.2.6	24-Jul-2013	riastradh	Tweak idr_pre_get. . No need to test kmem_alloc(n, KM_SLEEP) for NULL. . Avoid kmem_free with lock held, out of paranoia.
1.1.2.5	24-Jul-2013	riastradh	Add idr_for_each to Linux idr abstraction.
1.1.2.4	24-Jul-2013	riastradh	Implement idr_replace.
1.1.2.3	24-Jul-2013	riastradh	Implement idr_remove_all.
1.1.2.2	24-Jul-2013	riastradh	In linux_idr, move idr_temp access under the write lock. The atomic swaps were missing memory barriers, but using the rwlock is easier to understand for now. This should probably use passive serialization eventually anyway.
1.1.2.1	24-Jul-2013	riastradh	Dumb implementation of a subset of Linux's idr abstraction. An idr maintains a mapping from integers to data, like file descriptors to struct file pointers.

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.

1.1.2.3	08-Sep-2013	riastradh	Fix kunmap: unlike kunmap_atomic, it takes a page, not a vaddr. Unmapping the vaddr where the struct vm_page is stored makes for a rather confusing state of affairs!
1.1.2.2	24-Jul-2013	riastradh	Implement non-`atomic' kmap/kunmap in drm2 Linux shims. Uses uvm_km_alloc and pmap_kenter_pa. Does not use direct mappings on architectures that support this (e.g., amd64).

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	19-Dec-2021	riastradh	i915: more work
1.30	24-Jun-2024	riastradh	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.
1.29	23-Jun-2024	riastradh	linux_pci: Nix pci enumeration kludges. Now that we can pass a cookie through, this stuff will be a little less fragile.
1.28	19-May-2024	riastradh	linux: Add a few more cases to pci_get_class. Should fix crash on boot with amdgpu now that the ACPI business is enabled.
1.27	30-Sep-2023	mrg	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.
1.26	04-Sep-2023	mrg	convert a KASSERT() into an if () panic() sequence to appease GCC 12. OK riastradh@.
1.25	17-Oct-2022	mrg	branches: 1.25.2; add pcie capability and read request size linux compat, some pci root support implement support for: - pcie_capability_read_dword() - pcie_capability_read_word() - pcie_capability_write_dword() - pcie_capability_write_word() - pcie_get_readrq() - pcie_set_readrq() implement the "struct pci_dev" bus->self member by creating a minimal fake "struct pci_dev" for the pci bus itself. this is kind of gross. it checks that the current device's parent is a netbsd "pci" device, and that it has a (grand) parent "ppb" device, and then fills in the fake device based upon the pci and ppb devices. add some PCIE_LCSR2_TGT_LSPEED encodings, and map them to linux names. map several other PCIE_LCSR and PCIE_LCAP names. uncomment several pcie code segments in radeon and amdgpu. (not sure that we can test the amdgpu_si.c change, as we use the radeon version and the amdgpu version hangs on the one machine i have.) tested on amdgpu (RX550) and radeon (7750 & 3650). ok @riastradh
1.24	20-Sep-2022	mrg	fill out more of the linux pci API compat - implement pcie_get_speed_cap(), pcie_bandwidth_available(), and pci_is_root_bus(). - expand "enum pci_bus_speed" to add PCIe 5.x and 6.x speeds. - add "enum pcie_link_width". - add defines for PCIE_LCSR_LINKSPEED (PCIe generation) and PCIE_LCSR_NLW (negotiated lane width) to pcireg.h - enable amdgpu_device_get_pcie_info() code now it works. ok riastradh@
1.23	20-Jul-2022	riastradh	drm: Use real pci segment number, not pciN device unit.
1.22	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.

1.20	19-Dec-2021	riastradh	linux: pci_name

1.18	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.
1.17	19-Dec-2021	riastradh	Include acpica.h for NACPICA.

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	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.

1.4	09-Apr-2022	riastradh	sys: Use membar_release/acquire around reference drop. This just goes through my recent reference count membar audit and changes membar_exit to membar_release and membar_enter to membar_acquire -- this should make everything cheaper on most CPUs without hurting correctness, because membar_acquire is generally cheaper than membar_enter.
1.3	12-Mar-2022	riastradh	sys: Membar audit around reference count releases. If two threads are using an object that is freed when the reference count goes to zero, we need to ensure that all memory operations related to the object happen before freeing the object. Using an atomic_dec_uint_nv(&refcnt) == 0 ensures that only one thread takes responsibility for freeing, but it's not enough to ensure that the other thread's memory operations happen before the freeing. Consider: Thread A Thread B obj->foo = 42; obj->baz = 73; mumble(&obj->bar); grumble(&obj->quux); /* membar_exit(); / / membar_exit(); / atomic_dec -- not last atomic_dec -- last / membar_enter(); / KASSERT(invariant(obj->foo, obj->bar)); free_stuff(obj); The memory barriers ensure that obj->foo = 42; mumble(&obj->bar); in thread A happens before KASSERT(invariant(obj->foo, obj->bar)); free_stuff(obj); in thread B. Without them, this ordering is not guaranteed. So in general it is necessary to do membar_exit(); if (atomic_dec_uint_nv(&obj->refcnt) != 0) return; membar_enter(); to release a reference, for the `last one out hit the lights' style of reference counting. (This is in contrast to the style where one thread blocks new references and then waits under a lock for existing ones to drain with a condvar -- no membar needed thanks to mutex(9).) I searched for atomic_dec to find all these. Obviously we ought to have a better abstraction for this because there's so much copypasta. This is a stop-gap measure to fix actual bugs until we have that. It would be nice if an abstraction could gracefully handle the different styles of reference counting in use -- some years ago I drafted an API for this, but making it cover everything got a little out of hand (particularly with struct vnode::v_usecount) and I ended up setting it aside to work on psref/localcount instead for better scalability. I got bored of adding #ifdef __HAVE_ATOMIC_AS_MEMBAR everywhere, so I only put it on things that look performance-critical on 5sec review. We should really adopt membar_enter_preatomic/membar_exit_postatomic or something (except they are applicable only to atomic r/m/w, not to atomic_load/store_, making the naming annoying) and get rid of all the ifdefs.

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.

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.

1.9	04-Nov-2014	jmcneill	branches: 1.9.2; This code should be MP-safe. Use IPL_SCHED in place of IPL_DRM/IPL_VM and set D_MPSAFE flag in cdevsw.
1.8	29-Aug-2014	riastradh	Don't forget to lock wq_lock around handling wq_delayed.
1.7	29-Jul-2014	riastradh	branches: 1.7.2; 1.7.4; Linux wq locks are taken with spin locks held, so need IPL_VM.
1.6	27-Jul-2014	riastradh	Linux work is queued in intr context, so block intrs when locking. (Yes, this getting out of hand.)
1.5	25-Jul-2014	riastradh	This case is not supposed to fall through!
1.4	16-Jul-2014	riastradh	First whack at radeon driver. No hardware to test yet, but it builds.
1.3	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.
1.2	18-Mar-2014	riastradh	branches: 1.2.2; 1.2.4; 1.2.6; Merge riastradh-drm2 to HEAD.
1.1	30-Dec-2013	riastradh	branches: 1.1.2; file linux_work.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	22-Jan-2014	riastradh	Fix queue_delayed_work edge cases. - Copy the relevant part of queue_work in-line for ticks == 0, since queue_work itself will choke on a delayed work. - Don't reschedule the callout if it is already scheduled -- let it fire when it was already scheduled to fire.
1.1.2.8	30-Dec-2013	riastradh	Don't put work flush items on the stack; worker kmem_frees them.
1.1.2.7	30-Dec-2013	riastradh	Initialize the workqueue flush structures correctly.
1.1.2.6	30-Dec-2013	riastradh	Make Linux workqueues at IPL_VM for now.
1.1.2.5	30-Dec-2013	riastradh	Pass the wq to linux_worker as it expects, not NULL.
1.1.2.4	30-Dec-2013	riastradh	Actually insert the delayed work into the workqueue.
1.1.2.3	30-Dec-2013	riastradh	Helps to actually allocate and free the workqueue memory!
1.1.2.2	30-Dec-2013	riastradh	Add flush_scheduled_work back.
1.1.2.1	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.
1.2.6.2	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")

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)

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.

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.
