2021-09-03drm/nouveau/disp: power down unused DP links during initBen Skeggs3-1/+11
[ Upstream commit 6eaa1f3c59a707332e921e32782ffcad49915c5e ] When booted with multiple displays attached, the EFI GOP driver on (at least) Ampere, can leave DP links powered up that aren't being used to display anything. This confuses our tracking of SOR routing, with the likely result being a failed modeset and display engine hang. Fix this by (ab?)using the DisableLT IED script to power-down the link, restoring HW to a state the driver expects.

2021-09-03drm: Copy drm_wait_vblank to user before returningMark Yacoub1-3/+1
[ Upstream commit fa0b1ef5f7a694f48e00804a391245f3471aa155 ] [Why] Userspace should get back a copy of drm_wait_vblank that's been modified even when drm_wait_vblank_ioctl returns a failure. Rationale: drm_wait_vblank_ioctl modifies the request and expects the user to read it back. When the type is RELATIVE, it modifies it to ABSOLUTE and updates the sequence to become current_vblank_count + sequence (which was RELATIVE), but now it became ABSOLUTE. drmWaitVBlank (in libdrm) expects this to be the case as it modifies the request to be Absolute so it expects the sequence to would have been updated. The change is in compat_drm_wait_vblank, which is called by drm_compat_ioctl. This change of copying the data back regardless of the return number makes it en par with drm_ioctl, which always copies the data before returning. [How] Return from the function after everything has been copied to user.

commit c41a4e877a185241d8e83501453326fb98f67354 upstream. Building a randconfig here triggered: ERROR: modpost: "pm_suspend_target_state" [drivers/gpu/drm/amd/amdgpu/amdgpu.ko] undefined! because the module export of that symbol happens in kernel/power/suspend.c which is enabled with CONFIG_SUSPEND. The ifdef guards in amdgpu_acpi_is_s0ix_supported(), however, test for CONFIG_PM_SLEEP which is defined like this: config PM_SLEEP def_bool y depends on SUSPEND || HIBERNATE_CALLBACKS and that randconfig has: # CONFIG_SUSPEND is not set CONFIG_HIBERNATE_CALLBACKS=y leading to the module export missing.

2021-09-03drm/amdgpu: Cancel delayed work when GFXOFF is disabledMichel Dänzer2-17/+30
commit 32bc8f8373d2d6a681c96e4b25dca60d4d1c6016 upstream. schedule_delayed_work does not push back the work if it was already scheduled before, so amdgpu_device_delay_enable_gfx_off ran ~100 ms after the first time GFXOFF was disabled and re-enabled, even if GFXOFF was disabled and re-enabled again during those 100 ms. This resulted in frame drops / stutter with the upcoming mutter 41 release on Navi 14, due to constantly enabling GFXOFF in the HW and disabling it again (for getting the GPU clock counter). To fix this, call cancel_delayed_work_sync when the disable count transitions from 0 to 1, and only schedule the delayed work on the reverse transition, not if the disable count was already 0. This makes sure the delayed work doesn't run at unexpected times, and allows it to be lock-free. v2: * Use cancel_delayed_work_sync & mutex_trylock instead of mod_delayed_work. v3: * Make amdgpu_device_delay_enable_gfx_off lock-free (Christian König) v4: * Fix race condition between amdgpu_gfx_off_ctrl incrementing adev->gfx.gfx_off_req_count and amdgpu_device_delay_enable_gfx_off checking for it to be 0 (Evan Quan) Cc: stable@vger.kernel.org Reviewed-by: Evan Quan <evan.quan@amd.com> Reviewed-by: Lijo Lazar <lijo.lazar@amd.com> # v3 Acked-by: Christian König <christian.koenig@amd.com> # v3 Signed-off-by: Michel Dänzer <mdaenzer@redhat.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

commit 46dd2965bdd1c5a4f6499c73ff32e636fa8f9769 upstream. [Why] With kernel module parameter "freesync_video" is enabled, if the mode is changed to preferred mode(the mode with highest rate), then Freesync fails because the preferred mode is treated as one of freesync video mode, and then be configurated as freesync video mode(fixed refresh rate). [How] Skip freesync fixed rate configurating when modeset to preferred mode.

commit abd9d66a055722393d33685214c08386694871d7 upstream. Till DISPLAY12 the PIPE_MISC bits 5-7 are used to set the Dithering BPC, with valid values of 6, 8, 10 BPC. For ADLP+ these bits are used to set the PORT OUTPUT BPC, with valid values of: 6, 8, 10, 12 BPC, and need to be programmed whether dithering is enabled or not. This patch: -corrects the bits 5-7 for PIPE MISC register for 12 BPC. -renames the bits and mask to have generic names for these bits for dithering bpc and port output bpc. v3: Added a note for MIPI DSI which uses the PIPE_MISC for readout for pipe_bpp. (Uma Shankar) v2: Added 'display' to the subject and fixes tag.

2021-08-08Revert "drm/i915: Propagate errors on awaiting already signaled fences"Jason Ekstrand1-6/+2
commit 3761baae908a7b5012be08d70fa553cc2eb82305 upstream. This reverts commit 9e31c1fe45d555a948ff66f1f0e3fe1f83ca63f7. Ever since that commit, we've been having issues where a hang in one client can propagate to another. In particular, a hang in an app can propagate to the X server which causes the whole desktop to lock up. Error propagation along fences sound like a good idea, but as your bug shows, surprising consequences, since propagating errors across security boundaries is not a good thing. What we do have is track the hangs on the ctx, and report information to userspace using RESET_STATS. That's how arb_robustness works. Also, if my understanding is still correct, the EIO from execbuf is when your context is banned (because not recoverable or too many hangs). And in all these cases it's up to userspace to figure out what is all impacted and should be reported to the application, that's not on the kernel to guess and automatically propagate. What's more, we're also building more features on top of ctx error reporting with RESET_STATS ioctl: Encrypted buffers use the same, and the userspace fence wait also relies on that mechanism. So it is the path going forward for reporting gpu hangs and resets to userspace. So all together that's why I think we should just bury this idea again as not quite the direction we want to go to, hence why I think the revert is the right option here.

While this may improve perf for some workloads on Gen7 platforms where we rely on the command parser for features such as indirect rendering, no numbers were provided to prove such an improvement. It claims to closed two gitlab/bugzilla issues but with no explanation whatsoever as to why or what bug it's fixing. Meanwhile, by moving command parsing off to an async callback, it leaves us with a problem of what to do on error. When things were synchronous, EXECBUFFER2 would fail with an error code if parsing failed. When moving it to async, we needed another way to handle that error and the solution employed was to set an error on the dma_fence and then trust that said error gets propagated to the client eventually. Moving back to synchronous will help us untangle the fence error propagation mess. This also reverts most of 0edbb9ba1bfe ("drm/i915: Move cmd parser pinning to execbuffer") which is a refactor of some of our allocation paths for asynchronous parsing. Now that everything is synchronous, we don't need it. v2 (Daniel Vetter): - Add stabel Cc and Fixes tag Signed-off-by: Jason Ekstrand <jason@jlekstrand.net> Cc: <stable@vger.kernel.org> # v5.6+ Fixes: 9e31c1fe45d5 ("drm/i915: Propagate errors on awaiting already signaled fences") Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Reviewed-by: Jon Bloomfield <jon.bloomfield@intel.com> Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20210714193419.1459723-2-jason@jlekstrand.net Signed-off-by: Sasha Levin <sashal@kernel.org>

[ Upstream commit 7591c532b818ef4b8e3e635d842547c08b3a32b4 ] DP cable should always connect to DPU during the entire PHY compliance testing run. Since DP PHY compliance test is executed at irq_hpd event context, dp_ctrl_off_link_stream() should be used instead of dp_ctrl_off(). dp_ctrl_off() is used for unplug event which is triggered when DP cable is dis connected.

2021-08-04drm/amdgpu: Fix resource leak on probe error pathJiri Kosina1-6/+2
commit d47255d3f87338164762ac56df1f28d751e27246 upstream. This reverts commit 4192f7b5768912ceda82be2f83c87ea7181f9980. It is not true (as stated in the reverted commit changelog) that we never unmap the BAR on failure; it actually does happen properly on amdgpu_driver_load_kms() -> amdgpu_driver_unload_kms() -> amdgpu_device_fini() error path. What's worse, this commit actually completely breaks resource freeing on probe failure (like e.g. failure to load microcode), as amdgpu_driver_unload_kms() notices adev->rmmio being NULL and bails too early, leaving all the resources that'd normally be freed in amdgpu_acpi_fini() and amdgpu_device_fini() still hanging around, leading to all sorts of oopses when someone tries to, for example, access the sysfs and procfs resources which are still around while the driver is gone.

2021-08-04drm/amdgpu: Avoid printing of stack contents on firmware load errorJiri Kosina1-4/+3
commit 6aade587d329ebe88319dfdb8e8c7b6aede80417 upstream. In case when psp_init_asd_microcode() fails to load ASD microcode file, psp_v12_0_init_microcode() tries to print the firmware filename that failed to load before bailing out. This is wrong because: - the firmware filename it would want it print is an incorrect one as psp_init_asd_microcode() and psp_v12_0_init_microcode() are loading different filenames - it tries to print fw_name, but that's not yet been initialized by that time, so it prints random stack contents, e.g. amdgpu 0000:04:00.0: Direct firmware load for amdgpu/renoir_asd.bin failed with error -2 amdgpu 0000:04:00.0: amdgpu: fail to initialize asd microcode amdgpu 0000:04:00.0: amdgpu: psp v12.0: Failed to load firmware "\xfeTO\x8e\xff\xff" Fix that by bailing out immediately, instead of priting the bogus error message.
