The WA from commit 2a50edbf ("drm/amd/display: Apply w/a for hard hang on HPD") and commit 1bd3bc74 ("drm/amd/display: Extend w/a for hard hang on HPD to dcn20") causes a regression in s0ix where the system will fail to resume properly on many laptops. Pull the workarounds out to avoid that s0ix regression in the common case. This HPD hang happens with an external device in special circumstances and a new W/A will need to be developed for this in the future.

eb4fd29a ("drm/amdgpu: bind to any 0x1002 PCI diplay class device") added generic bindings to amdgpu so that that it binds to all display class devices with VID 0x1002 and then rejects those in amdgpu_pci_probe. Unfortunately it reuses a driver_data value of 0 to detect those new bindings, which is already used to denote CHIP_TAHITI ASICs. The driver_data value given to those new bindings was changed in dd0761fd24ea1 ("drm/amdgpu: set CHIP_IP_DISCOVERY as the asic type by default") to CHIP_IP_DISCOVERY (=36), but it seems that the check in amdgpu_pci_probe was forgotten to be changed. Therefore, it still rejects Tahiti GPUs.

It can cause a hang. This is normally not enabled for GPU hangs on these asics, but was recently enabled for handling aborted suspends. This causes hangs on some platforms on suspend.

Rather than opting into GPU recovery support, default to on, and opt out if it's not working on a particular GPU. This avoids the need to add new asics to this list since this is a core feature. Reviewed-by:

Even if it's probably not really useful, it can get selected by e.g. randconfig builds, and then failing to compile is an annoyance. Unfortunately, it's hard to fix in Kconfig, since DRM_TTM is selected by many things that don't really depend on any specific architecture, and just depend on PCI (which is indeed now available in ARCH=um via simulation/emulation). Fix this in the code instead by just ifdef'ing the relevant two lines that depend on "real X86". Reported-by:

The vga16fb framebuffer driver only supports Enhanced Graphics Adapter (EGA) and Video Graphics Array (VGA) 16 color graphic cards. But it doesn't check if the adapter is one of those or if a VGA16 mode is used. This means that the driver will be probed even if a VESA BIOS Extensions (VBE) or Graphics Output Protocol (GOP) interface is used. This issue has been present for a long time but it was only exposed by commit d391c582 ("drivers/firmware: move x86 Generic System Framebuffers support") since the platform device registration to match the {vesa,efi}fb drivers is done later as a consequence of that change. All non-x86 architectures though treat orig_video_isVGA as a boolean so only do the supported video mode check for x86 and not for other arches.

Harry Wentland authored
For some reason this file isn't using the appropriate register headers for DCN headers, which means that on DCN2 we're getting the VIEWPORT_DIMENSION offset wrong. This means that we're not correctly carving out the framebuffer memory correctly for a framebuffer allocated by EFI and therefore see corruption when loading amdgpu before the display driver takes over control of the framebuffer scanout. Fix this by checking the DCE_HWIP and picking the correct offset accordingly. Long-term we should expose this info from DC as GMC shouldn't need to know about DCN registers.

The remove_list head was only used for keeping track of existing ranges that are to be removed from the svms->list. The update_list was used for new or existing ranges that need updated attributes. These two cases are mutually exclusive (i.e. the same range will never be on both lists). Therefore we can use the update_list head to track the remove_list and save another 16 bytes in the svm_range struct. Signed-off-by:

There are seven list_heads in struct svm_range: list, update_list, remove_list, insert_list, svm_bo_list, deferred_list, child_list. This patch and the next one remove two of them that are redundant. The insert_list head was only used for new ranges that are not on the svms->list yet. So we can use that list head for keeping track of new ranges before they get added, and use list_move_tail to move them to the svms->list when ready. Signed-off-by:

Commit b5f57384 ("drm/amdkfd: Add sysfs bitfields and enums to uAPI") adds include/uapi/linux/kfd_sysfs.h with the "GPL-2.0 OR MIT WITH Linux-syscall-note" SPDX-License expression. The command ./scripts/spdxcheck.py warns: include/uapi/linux/kfd_sysfs.h: 1:48 Exception not valid for license MIT: Linux-syscall-note For a uapi header, the file under GPLv2 License must be combined with the Linux-syscall-note, but combining the MIT License with the Linux-syscall-note makes no sense, as the note provides an exception for GPL-licensed code, not for permissively licensed code. So, reorganize the SPDX expression to only combine the note with the GPL License condition. This makes spdxcheck happy again.
