2020-07-08drm/nouveau/nouveau: fix page fault on device private memoryRalph Campbell1-0/+1
If system memory is migrated to device private memory and no GPU MMU page table entry exists, the GPU will fault and call hmm_range_fault() to get the PFN for the page. Since the .dev_private_owner pointer in struct hmm_range is not set, hmm_range_fault returns an error which results in the GPU program stopping with a fatal fault. Fix this by setting .dev_private_owner appropriately.

2020-07-08drm/i915/gt: Pin the rings before marking activeChris Wilson1-6/+6
On eviction, we acquire the vm->mutex and then wait on the vma->active. Therefore when binding and pinning the vma, we must follow the same sequence, lock/pin the vma then mark it active. Otherwise, we mark the vma as active, then wait for the vm->mutex, and meanwhile the evictor holding the mutex waits upon us to complete our activity.

2020-07-07drm/i915/fbc: Fix fence_y_offset handlingVille Syrjälä4-25/+25
The current fence_y_offset calculation is broken. I think it more or less used to do the right thing, but then I changed the plane code to put the final x/y source offsets back into the src rectangle so now it's just subtraacting the same value from itself. The code would never have worked if we allowed the framebuffer to have a non-zero offset. Let's do this in a better way by just calculating the fence_y_offset from the final plane surface offset. Note that we don't align the plane surface address to fence rows so with horizontal panning there's often a horizontal offset from the fence start to the surface address as well. We have no way to tell the hardware about that so we just ignore it. Based on some quick tests the invlidation still happens correctly. I presume due to the invalidation nuking at least the full line (or a segment of multiple lines).

2020-07-07drm/i915: Skip stale object handle for debugfs per-file-statsChris Wilson1-1/+1
As we close a handle GEM object, we update the drm_file's idr with an error^W NULL pointer to indicate the in-progress closure, and finally removing it. If we read the idr directly, we may then see an invalid object pointer, and in our debugfs per_file_stats() we therefore need to protect against the entry being invalid.

The burst length is configured in VIU_OSD1_FIFO_CTRL_STAT[31] and VIU_OSD1_FIFO_CTRL_STAT[11:10]. The public S905D3 datasheet describes this as: - 0x0 = up to 24 per burst - 0x1 = up to 32 per burst - 0x2 = up to 48 per burst - 0x3 = up to 64 per burst - 0x4 = up to 96 per burst - 0x5 = up to 128 per burst The lower two bits map to VIU_OSD1_FIFO_CTRL_STAT[11:10] while the upper bit maps to VIU_OSD1_FIFO_CTRL_STAT[31]. Replace meson_viu_osd_burst_length_reg() with pre-defined macros which set these values. meson_viu_osd_burst_length_reg() always returned 0 (for the two used values: 32 and 64 at least) and thus incorrectly set the burst size to 24.

2020-07-01drm/amd/display: Only revalidate bandwidth on medium and fast updatesNicholas Kazlauskas1-4/+6
[Why] Changes that are fast don't require updating DLG parameters making this call unnecessary. Considering this is an expensive call it should not be done on every flip. DML touches clocks, p-state support, DLG params and a few other DC internal flags and these aren't expected during fast. A hang has been reported with this change when called on every flip which suggests that modifying these fields is not recommended behavior on fast updates. [How] Guard the validation to only happen if update type isn't FAST.

2020-06-30drm: sun4i: hdmi: Remove extra HPD pollingChen-Yu Tsai1-3/+2
The HPD sense mechanism in Allwinner's old HDMI encoder hardware is more or less an input-only GPIO. Other GPIO-based HPD implementations directly return the current state, instead of polling for a specific state and returning the other if that times out. Remove the I/O polling from sun4i_hdmi_connector_detect() and directly return a known state based on the current reading. This also gets rid of excessive CPU usage by kworker as reported on Stack Exchange [1] and Armbian forums [2].

2020-06-29drm/i915: Include asm sources for {ivb, hsw}_clear_kernel.cRodrigo Vivi3-0/+282
Alexandre Oliva has recently removed these files from Linux Libre with concerns that the sources weren't available. The sources are available on IGT repository, and only open source tools are used to generate the {ivb,hsw}_clear_kernel.c files. However, the remaining concern from Alexandre Oliva was around GPL license and the source not been present when distributing the code. So, it looks like 2 alternatives are possible, the use of linux-firmware.git repository to store the blob or making sure that the source is also present in our tree. Since the goal is to limit the i915 firmware to only the micro-controller blobs let's make sure that we do include the asm sources here in our tree. Btw, I tried to have some diligence here and make sure that the asms that these commits are adding are truly the source for the mentioned files: igt$ ./scripts/generate_clear_kernel.sh -g ivb \ -m ~/mesa/build/src/intel/tools/i965_asm Output file not specified - using default file "ivb-cb_assembled" Generating gen7 CB Kernel assembled file "ivb_clear_kernel.c" for i915 driver... igt$ diff ~/i915/drm-tip/drivers/gpu/drm/i915/gt/ivb_clear_kernel.c \ ivb_clear_kernel.c < * Generated by: IGT Gpu Tools on Fri 21 Feb 2020 05:29:32 AM UTC > * Generated by: IGT Gpu Tools on Mon 08 Jun 2020 10:00:54 AM PDT 61c61 < }; > }; \ No newline at end of file igt$ ./scripts/generate_clear_kernel.sh -g hsw \ -m ~/mesa/build/src/intel/tools/i965_asm Output file not specified - using default file "hsw-cb_assembled" Generating gen7.5 CB Kernel assembled file "hsw_clear_kernel.c" for i915 driver... igt$ diff ~/i915/drm-tip/drivers/gpu/drm/i915/gt/hsw_clear_kernel.c \ hsw_clear_kernel.c 5c5 < * Generated by: IGT Gpu Tools on Fri 21 Feb 2020 05:30:13 AM UTC > * Generated by: IGT Gpu Tools on Mon 08 Jun 2020 10:01:42 AM PDT 61c61 < }; > }; \ No newline at end of file Used IGT and Mesa master repositories from Fri Jun 5 2020) IGT: 53e8c878a6fb ("tests/kms_chamelium: Force reprobe after replugging the connector") Mesa: 5d13c7477eb1 ("radv: set keep_statistic_info with RADV_DEBUG=shaderstats") Mesa built with: meson build -D platforms=drm,x11 -D dri-drivers=i965 \ -D gallium-drivers=iris -D prefix=/usr \ -D libdir=/usr/lib64/ -Dtools=intel \ -Dkulkan-drivers=intel && ninja -C build v2: Header clean-up and include build instructions in a readme (Chris) Modified commit message to respect check-patch Reference: http://www.fsfla.org/pipermail/linux-libre/2020-June/003374.html Reference: http://www.fsfla.org/pipermail/linux-libre/2020-June/003375.html Fixes: 47f8253d2b89 ("drm/i915/gen7: Clear all EU/L3 residual contexts") Cc: <stable@vger.kernel.org> # v5.7+ Cc: Alexandre Oliva <lxoliva@fsfla.org> Cc: Prathap Kumar Valsan <prathap.kumar.valsan@intel.com> Cc: Akeem G Abodunrin <akeem.g.abodunrin@intel.com> Cc: Mika Kuoppala <mika.kuoppala@linux.intel.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Jani Nikula <jani.nikula@intel.com> Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Reviewed-by: Jon Bloomfield <jon.bloomfield@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200610201807.191440-1-rodrigo.vivi@intel.com (cherry picked from commit 5a7eeb8ba143d860050ecea924a8f074f02d8023) Signed-off-by: Jani Nikula <jani.nikula@intel.com>

Error appears when some i2c device driver tries to probe for devices using adapter registered by `smu_v11_0_i2c_eeprom_control_init()`. Code supporting this adapter requires `adev->psp.ras.ras` to be not NULL, which is true only when `amdgpu_ras_init()` detects HW support by calling `amdgpu_ras_check_supported()`. Before 9015d60c9ee1, adapter was registered by -> amdgpu_device_ip_init() -> amdgpu_ras_recovery_init() -> amdgpu_ras_eeprom_init() -> smu_v11_0_i2c_eeprom_control_init() after verifying that `adev->psp.ras.ras` is not NULL in `amdgpu_ras_recovery_init()`. Currently it is registered unconditionally by -> amdgpu_device_ip_init() -> pp_sw_init() -> hwmgr_sw_init() -> vega20_smu_init() -> smu_v11_0_i2c_eeprom_control_init() Fix simply adds HW support check (ras == NULL => no support) before calling `smu_v11_0_i2c_eeprom_control_{init,fini}()`. Please note that there is a chance that similar fix is also required for CHIP_ARCTURUS. I do not know whether any actual Arcturus hardware without RAS exist, and whether calling `smu_i2c_eeprom_init()` makes any sense when there is no HW support.
