thorpej | Re-factor the boot device and consinit routines into common functions per platform type (PCI vs TC), eliminating a bunch of copy-pasta.
|
| 1.24 |
| 04-Jul-2021 |
thorpej | branches: 1.24.16; Reduce code duplication when setting up the interrupt handler data structures: - alpha_shared_intr_alloc() no longer takes a "string length" argument, and just uses kmem_asprintf() to create an "irq %u" string by default. This is suitable for nearly every caller. - Add a alpha_shared_intr_set_string() that allows callers to override the default IRQ description string. - Related: make alpha_shared_intr_string() return a const char *, since no callers should need to modify the string directly now. - Re-factor PCI shared interrupt structure allocation / initialization into a new alpha_pci_intr_alloc(), which is suitable for nearly every Alpha PCI platform. Callers are expected to first have initialized the interrupt hardware to the quiescent state.
Adjust various call sites of above functions to account for changes, even if they are not able to use the newly re-factored code.

| 19-Jun-2021 |
thorpej | Don't use a bunch of switch() statements in the core logic drivers to select the PCI interrupt initialization routine. Instead, register said routines by systype in a link set, and look them up and invoke them in a new function alpha_pci_intr_init().
|
| 1.22 |
| 27-May-2021 |
thorpej | The Tsunami / Typhoon chipsets have a static "monster window" for DMA that allows for up to 32GB of RAM to be direct-mapped if the PCI device can issue a 64-bit address (the monster window lives at 0x10000000000). Enable this window and provide this to the PCI bus as a "dmat64".
|
| 1.21 |
| 26-Sep-2020 |
thorpej | branches: 1.21.6; 1.21.8; Implement cpu_intr_redistribute() for Tusnami/Titan systems.
|
| 1.20 |
| 26-Sep-2020 |
thorpej | Add support for CPU interrupt affinity for PCI interrupts: - Keep a bitmap of eligible interrupt-handling CPUs in the pci_chipset_tag_t. If this bitmap is 0, then we assume that all PCI interrupts should be routed to the primary CPU. - Add an optional PCI chipset callback for setting the CPU affinity of an interrupt. - When an establishing an interrupt handler, select the CPU that will handle this irq using the following algorithm: ==> If the irq already has a CPU assignment, keep it. ==> Otherwise, find the CPU with the fewest registered handlers that is eligible from both a hardware (based on the pci_chipset_tag_t) and software (based on cpu_info::ci_schedstate.spc_flags) perspectives. ==> Fall back to the primary CPU failing all else.

thorpej | Changes to make MPSAFE interrupts work on Alpha:
- Remove the ipl argument to scb_set() and the associated array of "mpsafe" booleans initialized based on the ipl. It was bogus anyway; all IPL_{BIO,NET,TTY}, etc. values are aliases of IPL_VM, and for all practical purposes, there is really only one device interrrupt level on Alpha anyway. Intead, we now treat all dispatches from the SCB vector table as MP-safe, and it is now the handler for that vector who is responsible for acquiring the KERNEL_LOCK if needed.
- Update the direct interrupt vector handlers in jensenio and TURBOchannel to acquire the KERNEL_LOCK.
- Introduce a new ALPHA_INTR_MPSAFE flag, and add a flags argument to alpha_shared_intr_establish(). When it is set, indicate that the handler is MP-safe. Update alpha_shared_intr_dispatch() to pay attention and acquire the KERNEL_LOCK (or not) as indicated.
- Re-factor all of the PCI interrupt handling, providing "generic PCI" "PCI interrupts through ISA IRQs" implementations to significantly reduce code duplication. Supplement the PCI chipset tag with more info to facilitate this, and make the PCI interrupt-related routines take a pci_chipset_tag_t argument rather than a void * argument.
- Because PCI interrupts on KN8AE are dispatched directly from the SCB, provide a wrapper for non-MPSAFE interrupt handlers that acquires the KERNEL_LOCK.
- Change the pci_intr_handle_t type to be a struct rather than an integer type in order to catch any direct use of it as a value. Add a set of functions to interact with pci_intr_handle_t, including setting interrupt flags.
- Implement pci_intr_setattr() so that the PCI_INTR_MPSAFE attribute can be set on a pci_intr_handle_t.
- While I'm here, make all of the MI PCI back-end operations call through real functions rather than hopping directly through function pointers in the chipset tag.
This change looks a lot bigger than it really is because of the re-factor in the plethora of model-specific PCI interrupt back-ends. The KN8AE, KN300, and T2/T3/T4 (Sable) are largely un-changed.

christos | make pci_intr_string and eisa_intr_string take a buffer and a length instead of relying in local static storage.
|
| 1.17 |
| 21-Mar-2014 |
christos | gc sprintf; reduce local static usage of interrupt strings that are only used once for autoconf printing.
|
| 1.16 |
| 20-Jan-2014 |
tsutsui | Check and set "is_console" property to PCI displays for framebuffer drivers.
Tested on DS15 with radeonfb(4) and XP1000 with vga(4) by Naruaki Etomi in PR/48431.

| 1.15 |
| 06-Feb-2012 |
matt | branches: 1.15.6; 1.15.10; Do a minor cleanup of alpha (this will make applying pullups post branching easier). u_int{8,16,32,64}_t -> uint{*}_t Change all old-style definitions to C89 prototypes. Whitespace cleanup. Constification in db_disasm.c
|
| 1.14 |
| 14-Jun-2011 |
matt | branches: 1.14.2; 1.14.6; struct device * -> device_t
|

| 04-Apr-2011 |
dyoung | branches: 1.13.2; Neither pci_dma64_available(), pci_probe_device(), pci_mapreg_map(9), pci_find_rom(), pci_intr_map(9), pci_enumerate_bus(), nor the match predicate passed to pciide_compat_intr_establish() should ever modify their pci_attach_args argument, so make their pci_attach_args arguments const and deal with the fallout throughout the kernel.
For the most part, these changes add a 'const' where there was no 'const' before, however, some drivers and MD code used to modify pci_attach_args. Now those drivers either copy their pci_attach_args and modify the copy, or refrain from modifying pci_attach_args:
Xen: according to Manuel Bouyer, writing to pci_attach_args in pci_intr_map() was a leftover from Xen 2. Probably a bug. I stopped writing it. I have not tested this change.
siside(4): sis_hostbr_match() needlessly wrote to pci_attach_args. Probably a bug. I use a temporary variable. I have not tested this change.
slide(4): sl82c105_chip_map() overwrote the caller's pci_attach_args. Probably a bug. Use a local pci_attach_args. I have not tested this change.
viaide(4): via_sata_chip_map() and via_sata_chip_map_new() overwrote the caller's pci_attach_args. Probably a bug. Make a local copy of the caller's pci_attach_args and modify the copy. I have not tested this change.
While I'm here, make pci_mapreg_submap() static.
With these changes in place, I have tested the compilation of these kernels:

|

thorpej | branches: 1.10.10; Let machine-dependent code specify how to enumerate the bus. Currently, everyone uses pci_enumerate_bus_generic().

thorpej | (*pc_decompose_tag)() is no longer alpha specific. Move it as appropriate.
|
| 1.8 |
| 15-May-2002 |
thorpej | Rename alpha_pci_decompose_tag() to pci_decompose_tag(). There *is* some MI PCI code that uses it, and soon there will be more. (The rationale for not making it available previously was that it could be mis-used, but that's true of a lot of things.)
|
| 1.7 |
| 08-Jun-2001 |
simonb | branches: 1.7.2; 1.7.4; For ports that wire up pciide in compatibility mode, have them define __HAVE_PCIIDE_MACHDEP_COMPAT_INTR_ESTABLISH in pci_machdep.h and pciide_map_compat_intr() only calls pciide_machdep_compat_intr_establish() if that preprocessor define exists.
Ports that don't need to do this no longer need to supply a dummy function.
|
| 1.6 |
| 28-Dec-2000 |
sommerfeld | branches: 1.6.2; Change pci_intr_map to get interrupt source information from a "struct pci_attach_args *" instead of from four separate parameters which in all cases were extracted from the same "struct pci_attach_args".
This both simplifies the driver api, and allows for alternate PCI interrupt mapping schemes, such as one using the tables described in the Intel Multiprocessor Spec which describe interrupt wirings for devices behind pci-pci bridges based on the device's location rather the bridge's location.
Tested on alpha and i386; welcome to 1.5Q

cgd | Implement the more flexiable `evcnt' interface as discussed (briefly) on tech-kern and now documented in evcnt(9).
|
| 1.4 |
| 01-Jun-2000 |
cgd | kill __P in these files. (I had to look at them anyway with an eye for adding some protos... and adding them with __P seems wrong, but mixing __P and not __P in the same file seems wrong too, so...)
|
| 1.3 |
| 19-Mar-1999 |
cgd | branches: 1.3.8; 1.3.16; move pci/pci_machdep.h to include/pci_machdep.h. (can't do it via repository copy because alpha already had an include/pci_machdep.h in the attic.)
|
| 1.2 |
| 12-Apr-1996 |

|
| 1.1 |
| 23-Nov-1995 |
cgd | wholesale update from my NetBSD/Alpha source tree. Includes: Support for AXPpci CPUs, Support for AlphaStation 600 CPUs, new boot block structure, which requires an 'installboot' program and works a lot like the NetBSD/sparc boot blocks.
