2023-04-26drm/rockchip: vop2: Use regcache_sync() to fix suspend/resumeSascha Hauer1-7/+3
commit b63a553e8f5aa6574eeb535a551817a93c426d8c upstream. afa965a45e01 ("drm/rockchip: vop2: fix suspend/resume") uses regmap_reinit_cache() to fix the suspend/resume issue with the VOP2 driver. During discussion it came up that we should rather use regcache_sync() instead. As the original patch is already applied fix this up in this follow-up patch.

2023-04-26drm/rockchip: vop2: fix suspend/resumeSascha Hauer1-0/+8
commit afa965a45e01e541cdbe5c8018226eff117610f0 upstream. During a suspend/resume cycle the VO power domain will be disabled and the VOP2 registers will reset to their default values. After that the cached register values will be out of sync and the read/modify/write operations we do on the window registers will result in bogus values written. Fix this by re-initializing the register cache each time we enable the VOP2. With this the VOP2 will show a picture after a suspend/resume cycle whereas without this the screen stays dark.

2023-04-26drm/amdgpu: Fix desktop freezed after gpu-resetAlan Liu2-3/+17
commit c8b5a95b570949536a2b75cd8fc4f1de0bc60629 upstream. [Why] After gpu-reset, sometimes the driver fails to enable vblank irq, causing flip_done timed out and the desktop freezed. During gpu-reset, we disable and enable vblank irq in dm_suspend() and dm_resume(). Later on in amdgpu_irq_gpu_reset_resume_helper(), we check irqs' refcount and decide to enable or disable the irqs again. However, we have 2 sets of API for controling vblank irq, one is dm_vblank_get/put() and another is amdgpu_irq_get/put(). Each API has its own refcount and flag to store the state of vblank irq, and they are not synchronized. In drm we use the first API to control vblank irq but in amdgpu_irq_gpu_reset_resume_helper() we use the second set of API. The failure happens when vblank irq was enabled by dm_vblank_get() before gpu-reset, we have vblank->enabled true. However, during gpu-reset, in amdgpu_irq_gpu_reset_resume_helper() vblank irq's state checked from amdgpu_irq_update() is DISABLED. So finally it disables vblank irq again. After gpu-reset, if there is a cursor plane commit, the driver will try to enable vblank irq by calling drm_vblank_enable(), but the vblank->enabled is still true, so it fails to turn on vblank irq and causes flip_done can't be completed in vblank irq handler and desktop become freezed. [How] Combining the 2 vblank control APIs by letting drm's API finally calls amdgpu_irq's API, so the irq's refcount and state of both APIs can be synchronized. Also add a check to prevent refcount from being less then 0 in amdgpu_irq_put(). v2: - Add warning in amdgpu_irq_enable() if the irq is already disabled. - Call dc_interrupt_set() in dm_set_vblank() to avoid refcount change if it is in gpu-reset. v3: - Improve commit message and code comments.

2023-04-26drm/amdgpu/vcn: Disable indirect SRAM on Vangogh broken BIOSesGuilherme G. Piccoli1-0/+17
commit 542a56e8eb4467ae654eefab31ff194569db39cd upstream. The VCN firmware loading path enables the indirect SRAM mode if it's advertised as supported. We might have some cases of FW issues that prevents this mode to working properly though, ending-up in a failed probe. An example below, observed in the Steam Deck: [...] [drm] failed to load ucode VCN0_RAM(0x3A) [drm] psp gfx command LOAD_IP_FW(0x6) failed and response status is (0xFFFF0000) amdgpu 0000:04:00.0: [drm:amdgpu_ring_test_helper [amdgpu]] *ERROR* ring vcn_dec_0 test failed (-110) [drm:amdgpu_device_init.cold [amdgpu]] *ERROR* hw_init of IP block <vcn_v3_0> failed -110 amdgpu 0000:04:00.0: amdgpu: amdgpu_device_ip_init failed amdgpu 0000:04:00.0: amdgpu: Fatal error during GPU init [...] Disabling the VCN block circumvents this, but it's a very invasive workaround that turns off the entire feature. So, let's add a quirk on VCN loading that checks for known problematic BIOSes on Vangogh, so we can proactively disable the indirect SRAM mode and allow the HW proper probe and VCN IP block to work fine.

2023-04-26drm: test: Fix 32-bit issue in drm_buddy_testDavid Gow1-1/+2
[ Upstream commit 25bbe844ef5c4fb4d7d8dcaa0080f922b7cd3a16 ] The drm_buddy_test KUnit tests verify that returned blocks have sizes which are powers of two using is_power_of_2(). However, is_power_of_2() operations on a 'long', but the block size is a u64. So on systems where long is 32-bit, this can sometimes fail even on correctly sized blocks. This only reproduces randomly, as the parameters passed to the buddy allocator in this test are random. The seed 0xb2e06022 reproduced it fine here. For now, just hardcode an is_power_of_2() implementation using x & (x - 1).

[ Upstream commit 4453545b5b4c3eff941f69a5530f916d899db025 ] The drm buddy allocator tests were broken on 32-bit systems, as rounddown_pow_of_two() takes a long, and the buddy allocator handles 64-bit sizes even on 32-bit systems. This can be reproduced with the drm_buddy_allocator KUnit tests on i386: ./tools/testing/kunit/kunit.py run --arch i386 \ --kunitconfig ./drivers/gpu/drm/tests drm_buddy (It results in kernel BUG_ON() when too many blocks are created, due to the block size being too small.) This was independently uncovered (and fixed) by Luís Mendes, whose patch added a new u64 variant of rounddown_pow_of_two(). This version instead recalculates the size based on the order.

commit eb50912ec931913e70640cecf75cb993fd26995f upstream. Use the correct old/new topology and payload states in intel_mst_disable_dp(). So far drm_atomic_get_mst_topology_state() it used returned either the old state, in case the state was added already earlier during the atomic check phase or otherwise the new state (but the latter could fail, which can't be handled in the enable/disable hooks). After the first patch in the patchset, the state should always get added already during the check phase, so here we can get the old/new states without a failure. drm_dp_remove_payload() should use time_slots from the old payload state and vc_start_slot in the new one. It should update the new payload states to reflect the sink's current payload table after the payload is removed. Pass the new topology state and the old and new payload states accordingly. This also fixes a problem where the payload allocations for multiple MST streams on the same link got inconsistent after a few commits, as during payload removal the old instead of the new payload state got updated, so the subsequent enabling sequence and commits used a stale payload state. v2: Constify the old payload state pointer.

2023-04-13drm/display/dp_mst: Handle old/new payload states in drm_dp_remove_payload()Imre Deak4-15/+19
commit e761cc20946a0094df71cb31a565a6a0d03bd8be upstream. Atm, drm_dp_remove_payload() uses the same payload state to both get the vc_start_slot required for the payload removal DPCD message and to deduct time_slots from vc_start_slot of all payloads after the one being removed. The above isn't always correct, as vc_start_slot must be the up-to-date version contained in the new payload state, but time_slots must be the one used when the payload was previously added, contained in the old payload state. The new payload's time_slots can change vs. the old one if the current atomic commit changes the corresponding mode. This patch let's drivers pass the old and new payload states to drm_dp_remove_payload(), but keeps these the same for now in all drivers not to change the behavior. A follow-up i915 patch will pass in that driver the correct old and new states to the function.

commit dc3421560a67361442f33ec962fc6dd48895a0df upstream. When considering whether to mark one context as stopped and another as started we need to look at whether the previous and new _contexts_ are different and not just requests. Otherwise the software tracked context start time was incorrectly updated to the most recent lite-restore time- stamp, which was in some cases resulting in active time going backward, until the context switch (typically the heartbeat pulse) would synchronise with the hardware tracked context runtime. Easiest use case to observe this behaviour was with a full screen clients with close to 100% engine load.

To make it possible that a driver signals such a failure change the prototype of .get_state() to return an error code. This patch was created using coccinelle and the following semantic patch: @p1@ identifier getstatefunc; identifier driver; @@ struct pwm_ops driver = { ..., .get_state = getstatefunc ,... }; @p2@ identifier p1.getstatefunc; identifier chip, pwm, state; @@ -void +int getstatefunc(struct pwm_chip *chip, struct pwm_device *pwm, struct pwm_state *state) { ... - return; + return 0; ... } plus the actual change of the prototype in include/linux/pwm.h (plus some manual fixing of indentions and empty lines). So for now all drivers return success unconditionally. They are adapted in the following patches to make the changes easier reviewable.

2023-04-06drm/i915: Move CSC load back into .color_commit_arm() when PSR is enabled on ↵Ville Syrjälä1-2/+21
skl/glk commit a8e03e00b62073b494886dbff32f8b5338066c8b upstream. SKL/GLK CSC unit suffers from a nasty issue where a CSC coeff/offset register read or write between DC5 exit and PSR exit will undo the CSC arming performed by DMC, and then during PSR exit the hardware will latch zeroes into the active CSC registers. This causes any plane going through the CSC to output all black. We can sidestep the issue by making sure the PSR exit has already actually happened before we touch the CSC coeff/offset registers. Easiest way to guarantee that is to just move the CSC programming back into the .color_commir_arm() as we force a PSR exit (and crucially wait for it to actually happen) prior to touching the arming registers. When PSR (and thus also DC states) are disabled we don't have anything to worry about, so we can keep using the more optional _noarm() hook for writing the CSC registers.

2023-04-06drm/i915: Disable DC states for all commitsVille Syrjälä1-3/+25
commit a2b6e99d8a623544f3bdccd28ee35b9c1b00daa5 upstream. Keeping DC states enabled is incompatible with the _noarm()/_arm() split we use for writing pipe/plane registers. When DC5 and PSR are enabled, all pipe/plane registers effectively become self-arming on account of DC5 exit arming the update, and PSR exit latching it. What probably saves us most of the time is that (with PIPE_MISC[21]=0) all pipe register writes themselves trigger PSR exit, and then we don't re-enter PSR until the idle frame count has elapsed. So it may be that the PSR exit happens already before we've updated the state too much. Also the PSR1 panel (at least on this KBL) seems to discard the first frame we trasmit, presumably still scanning out from its internal framebuffer at that point. So only the second frame we transmit is actually visible. But I suppose that could also be panel specific behaviour. I haven't checked out how other PSR panels behave, nor did I bother to check what the eDP spec has to say about this. And since this really is all about DC states, let's switch from the MODESET domain to the DC_OFF domain. Functionally they are 100% identical. We should probably remove the MODESET domain... And for good measure let's toss in an assert to the place where we do the _noarm() register writes to make sure DC states are in fact off. v2: Just use intel_display_power_is_enabled() (Imre) Cc: <stable@vger.kernel.org> #v5.17+ Cc: Manasi Navare <navaremanasi@google.com> Cc: Drew Davenport <ddavenport@chromium.org> Cc: Jouni Högander <jouni.hogander@intel.com> Reviewed-by: Imre Deak <imre.deak@intel.com> Fixes: d13dde449580 ("drm/i915: Split pipe+output CSC programming to noarm+arm pair") Fixes: f8a005eb8972 ("drm/i915: Optimize icl+ universal plane programming") Fixes: 890b6ec4a522 ("drm/i915: Split skl+ plane update into noarm+arm pair") Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230320183532.17727-1-ville.syrjala@linux.intel.com (cherry picked from commit 41b4c7fe72b6105a4b49395eea9aa40cef94288d) Signed-off-by: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

commit 3413881e1ecc3cba722a2e87ec099692eed5be28 upstream. Currently i915_gem_object_is_framebuffer() doesn't treat the BO containing the framebuffer's DPT as a framebuffer itself. This means eg. that the shrinker can evict the DPT BO while leaving the actual FB BO bound, when the DPT is allocated from regular shmem. That causes an immediate oops during hibernate as we try to rewrite the PTEs inside the already evicted DPT obj. TODO: presumably this might also be the reason for the DPT related display faults under heavy memory pressure, but I'm still not sure how that would happen as the object should be pinned by intel_dpt_pin() while in active use by the display engine...

[ Upstream commit 1a5b5372e3b0a4cc65a0cbb724b1b0859f4ac63c ] The sc7280_pp declaration is not located by the other _pp declarations, but rather hidden around the _merge_3d declarations. Let's fix this to avoid confusion.

2023-03-30drm/amdkfd: Fix the warning of array-index-out-of-boundsMa Jun4-292/+282
commit c0cc999f3c32e65a7c88fb323893ddf897b24488 upstream. For some GPUs with more CUs, the original sibling_map[32] in struct crat_subtype_cache is not enough to save the cache information when create the VCRAT table, so skip filling the struct crat_subtype_cache info instead fill struct kfd_cache_properties directly to fix this problem.
