Pull drm fixes from Dave Airlie: "Weekly fixes round, looks like a few people woke up, got a bunch of fixes across the drivers. Bit bigger than I'd like but they all seem fine and hopefully it quiets down now. sun4i, kirin, mediatek and exynos on the ARM side. virtio-gpu and core have some mmap fixes, and there is a dma-buf leak. one ttm fence leak is also fixed. Otherwise it's mostly amdgpu and i915. One of the i915 fixes is for a very long latency I was seeing (using latencytop) running gnome-shell locally when using firefox and eating nearly all my RAM, it really helps with desktop responsiveness esp when firefox is chewing a lot. dma-buf: - fix memory leak core: - shmem object mmap fix. ttm: - Fix fence leak in ttm_buffer_object_transfer(). amdgpu: - Gfx reset fix for gfx9, 10 - Fix for gfx10 - DP MST fix - DCC fix - Renoir power fixes - Navi power fix i915: - Break up long lists of object reclaim with cond_resched() - PSR probe fix - TGL workarounds - Selftest return value fix - Drop timeline mutex while waiting for retirement - Wait for OA configuration completion before writes to OA buffer virtio: - Fix resource id creation race in virtio. - mmap fixes sun4i: - Fixes for sun4i VI layer format support. kirin: - kirin: Revert "Fix for hikey620 display offset problem" exynos: - fix a kernel oops problem in case that driver is loaded as module. - fix a regulator warning issue when I2C DDC adapter cannot be gathered. - print out an error message only in error case excepting -EPROBE_DEFER. mediatek: - overlay, cursor and gce fixes" ` * tag 'drm-fixes-2020-03-06' of git://anongit.freedesktop.org/drm/drm: (38 commits) drm/amdgpu/display: navi1x copy dcn watermark clock settings to smu resume from s3 (v2) drm/amd/powerplay: map mclk to fclk for COMBINATIONAL_BYPASS case drm/amd/powerplay: fix pre-check condition for setting clock range drm/amd/display: fix dcc swath size calculations on dcn1 drm/amd/display: Clear link settings on MST disable connector drm/amdgpu: disable 3D pipe 1 on Navi1x drm/amdgpu: clean wptr on wb when gpu recovery drm: kirin: Revert "Fix for hikey620 display offset problem" drm/i915/gt: Drop the timeline->mutex as we wait for retirement drm/i915/perf: Reintroduce wait on OA configuration completion drm/sun4i: Fix DE2 VI layer format support drm/sun4i: Add separate DE3 VI layer formats drm/sun4i: de2/de3: Remove unsupported VI layer formats drm/i915/selftests: Fix return in assert_mmap_offset() drm/i915: Protect i915_request_await_start from early waits drm/i915/tgl: Add Wa_1608008084 drm/i915/tgl: Add Wa_22010178259:tgl drm/i915: Program MBUS with rmw during initialization drm/i915/psr: Force PSR probe only after full initialization drm/i915/gem: Break up long lists of object reclaim ...

This interface is for dGPU Navi1x. Linux dc-pplib interface depends on window driver dc implementation. For Navi1x, clock settings of dcn watermarks are fixed. the settings should be passed to smu during boot up and resume from s3. boot up: dc calculate dcn watermark clock settings within dc_create, dcn20_resource_construct, then call pplib functions below to pass the settings to smu: smu_set_watermarks_for_clock_ranges smu_set_watermarks_table navi10_set_watermarks_table smu_write_watermarks_table For Renoir, clock settings of dcn watermark are also fixed values. dc has implemented different flow for window driver: dc_hardware_init / dc_set_power_state dcn10_init_hw notify_wm_ranges set_wm_ranges For Linux smu_set_watermarks_for_clock_ranges renoir_set_watermarks_table smu_write_watermarks_table dc_hardware_init -> amdgpu_dm_init dc_set_power_state --> dm_resume therefore, linux dc-pplib interface of navi10/12/14 is different from that of Renoir. v2: add missing unlock in error case Signed-off-by:

[Why] Swath sizes are being calculated incorrectly. The horizontal swath size should be the product of block height, viewport width, and bytes per element, but the calculation uses viewport height instead of width. The vertical swath size is similarly incorrectly calculated. The effect of this is that we report the wrong DCC caps. [How] Use viewport width in the horizontal swath size calculation and viewport height in the vertical swath size calculation. Signed-off-by:

The TDR will be randomly failed due to compute ring test failure. If the compute ring wptr & 0x7ff(ring_buf_mask) is 0x100 then after map mqd the compute ring rptr will be synced with 0x100. And the ring test packet size is also 0x100. Then after invocation of amdgpu_ring_commit, the cp will not really handle the packet on the ring buffer because rptr is equal to wptr. Signed-off-by:

This reverts commit ff57c651. With the commit ff57c651 ("drm: kirin: Fix for hikey620 display offset problem") we added support for handling LDI overflows by resetting the hardware. However, its been observed that when we do hit the LDI overflow condition, the irq seems to be screaming, and we do nothing but stream: [drm:ade_irq_handler [kirin_drm]] *ERROR* LDI underflow! over and over to the screen I've tried a few appraoches to avoid this, but none has yet been successful and the cure here is worse then the original disease, so revert this for now.

As we have pinned the timeline (using tl->active_count), we can safely drop the tl->mutex as we wait for what we believe to be the final request on that timeline. This is useful for ensuring that we do not block the engine heartbeat by hogging the kernel_context's timeline on a dead GPU.

There's also a READ_ONCE() fix for reading an mmap-ed EFI firmware data field only once, out of caution" * 'efi-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: efi: READ_ONCE rng seed size before munmap efi/x86: Handle by-ref arguments covering multiple pages in mixed mode efi/x86: Remove support for EFI time and counter services in mixed mode efi/x86: Align GUIDs to their size in the mixed mode runtime wrapper

The assert_mmap_offset() returns type bool so if we return an error pointer that is "return true;" or success. If we have an error, then we should return false. Fixes: 3d81d589 ("drm/i915: Test exhaustion of the mmap space") Signed-off-by:

We need to be extremely careful inside i915_request_await_start() as it needs to walk the list of requests in the foreign timeline with very little protection. As we hold our own timeline mutex, we can not nest inside the signaler's timeline mutex, so all that remains is our RCU protection. However, to be safe we need to tell the compiler that we may be traversing the list only under RCU protection, and furthermore we need to start declaring requests as elements of the timeline from their construction.

Wa_1608008084 is an additional WA that applies to writes on FF_MODE2 register. We can't read it back either from CPU or GPU. Since the other bits should be 0, recommendation to handle Wa_1604555607 is to actually just write the timer value. Do a write only and don't try to read it, neither before or after the WA is applied. Fixes: ff690b21 ("drm/i915/tgl: Implement Wa_1604555607") Signed-off-by:

We need to explicitly set the TLB Request Timer initial value in the BW_BUDDY registers to 0x8 rather than relying on the hardware default. v2: Apply missing REG_FIELD_PREP to ensure 0x8 is placed in the correct bits during the rmw.

It wasn't terribly clear from the bspec's wording, but after discussion with the hardware folks, it turns out that we need to preserve the pre-existing contents of the MBUS ABOX control register when initializing a few specific bits.

Commit 60c6a14b ("drm/i915/display: Force the state compute phase once to enable PSR") was forcing the state compute too earlier causing errors because not everything was initialized, so here moving to the end of i915_driver_modeset_probe() when the display is all initialized. Also fixing the place where it disarm the force probe as during the atomic check phase errors could happen like the ones due locking and it would cause PSR to never be enabled if that happens. Leaving the disarm to the atomic commit phase, intel_psr_enable() or intel_psr_update() will be called even if the current state do not allow PSR to be enabled. v2: Check if intel_dp is null in intel_psr_force_mode_changed_set() v3: Check intel_dp before get dev_priv v4: - renamed intel_psr_force_mode_changed_set() to intel_psr_set_force_mode_changed() - removed the set parameter from intel_psr_set_force_mode_changed() - not calling intel_psr_set_force_mode_changed() from intel_psr_enable/update(), directly setting it after the same checks that intel_psr_set_force_mode_changed() does - moved intel_psr_set_force_mode_changed() arm call to i915_driver_modeset_probe() as it is a better for a PSR call, all the functions calls happening between the old and the new function call will cause issue [backported to v5.6-rc3] Fixes: 60c6a14b ("drm/i915/display: Force the state compute phase once to enable PSR") Closes: https://gitlab.freedesktop.org/drm/intel/issues/1151Tested-by:
