2020-05-05drm/tidss: remove AM65x PG1 YUV erratum codeTomi Valkeinen
AM65x PG1 has a HW issue with YUV pixel formats, resulting in wrong colors on the screen. This issue is fixed in PG2 hardware. The driver currently has code to hide YUV pixel formats from the userspace. To support PG2, we would need to add code to detect the SoC version and hide the YUV formats based on that. However, as PG1 will be phased out and PG2 will be the main platform, a much simpler solution is just to drop the code in question. The downside is that the users will be able to use YUV formats on PG1, getting wrong colors on the screen. On the other hand, that may also be a plus, as the same applications will now work on PG1 and PG2, even if the colors are wrong on PG1.

2020-05-05drm/omap: change default signal polarities and drivesTomi Valkeinen
If the given videomode does not specify DISPLAY_FLAG_* for the specific signal property, the driver used a default value. These defaults were never thought through, as the expectation was that all the DISPLAY_FLAGS are always set explicitly. With DRM bridge and panel drivers this is not the case, and while that issue should be resolved in the future, it's still good to have sane signal defaults. This patch changes the defaults to what the hardware has as reset defaults. Also, based on my experience, I think they make sense and are more likely correct than the defaults without this patch.

There might still be a few overflows, namely when calculating link_clks_available/samples_room (would require a huge hblank though), and potentially when calculating hblank_rise (not sure how large link_clks_active can get). It looks like we're still not calculating exactly what the spec says since we truncate tu_data and tu_line early.

2020-05-04drm/i915/fbc: Require linear fb stride to be multiple of 512 bytes on gen9/glkVille Syrjälä
Display WA #1105 says that FBC requires PLANE_STRIDE to be a multiple of 512 bytes on gen9 and glk. This is definitely true for glk as certain tests (such as igt/kms_big_fb/linear-16bpp-rotate-0) are now failing when the display resolution results in a plane stride which is not a multiple of 512 bytes. Curiously I was not able to reproduce this on a KBL. First I suspected that our use of the FBC override stride explain this, but after trying to use the override stride on glk the test still failed. I did try both the old CHICKEN_MISC_4 way and the new FBC_STRIDE way, neither had any effect on the result. Anyways, we need this at least on glk. But let's trust the spec and apply the w/a for all gen9 as well, despite being unable to reproduce the problem. v2: s/FBC_CHICKEN/FBC_STRIDE/ in commit msg Cc: José Roberto de Souza <jose.souza@intel.com> Fixes: 691f7ba58d52 ("drm/i915/display/fbc: Make fences a nice-to-have for GEN9+") Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200429101034.8208-2-ville.syrjala@linux.intel.com Reviewed-by: Matt Roper <matthew.d.roper@intel.com>

2020-05-04drm/i915/gem: Implement legacy MI_STORE_DATA_IMMChris Wilson
The older arches did not convert MI_STORE_DATA_IMM to using the GTT, but left them writing to a physical address. The notes suggest that the primary reason would be so that the writes were cache coherent, as the CPU cache uses physical tagging. As such we did not implement the legacy variant of MI_STORE_DATA_IMM and so left all the relocations synchronous -- but with a small function to convert from the vma address into the physical address, we can implement asynchronous relocs on these older arches, fixing up a few tests that require them. In order to be able to test the legacy paths, refactor the gpu relocations so that we can hook them up to a selftest. v2: Use an array of offsets not enum labels for the selftest v3: Refactor the common igt_hexdump() Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/757 Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200504140629.28240-1-chris@chris-wilson.co.uk

2020-05-01drm/i915/gem: Try an alternate engine for relocationsChris Wilson
If at first we don't succeed, try try again. Not all engines may support the MI ops we need to perform asynchronous relocation patching, and so we end up falling back to a synchronous operation that has a liability of blocking. However, Tvrtko pointed out we don't need to use the same engine to perform the relocations as we are planning to execute the execbuf on, and so if we switch over to a working engine, we can perform the relocation asynchronously. The user execbuf will be queued after the relocations by virtue of fencing. This patch creates a new context per execbuf requiring asynchronous relocations on an unusable engines. This is perhaps a bit excessive and can be ameliorated by a small context cache, but for the moment we only need it for working around a little used engine on Sandybridge, and only if relocations are actually required to an active batch buffer. Now we just need to teach the relocation code to handle physical addressing for gen2/3, and we should then have universal support!

2020-05-01drm/i915/gem: Use chained reloc batchesChris Wilson
The ring is a precious resource: we anticipate to only use a few hundred bytes for a request, and only try to reserve that before we start. If we go beyond our guess in building the request, then instead of waiting at the start of execbuf before we hold any locks or other resources, we may trigger a wait inside a critical region. One example is in using gpu relocations, where currently we emit a new MI_BB_START from the ring every time we overflow a page of relocation entries. However, instead of insert the command into the precious ring, we can chain the next page of relocation entries as MI_BB_START from the end of the previous. v2: Delay the emit_bb_start until after all the chained vma synchronisation is complete. Since the buffer pool batches are idle, this _should_ be a no-op, but one day we may some fancy async GPU bindings for new vma! v3: Use pool/batch consitently, once we start thinking in terms of the batch vma, use batch->obj. v4: Explain the magic number 4. Tvrtko spotted that we lose propagation of the error for failing to submit the relocation request; that's easier to fix up in the next patch.

2020-05-01drm/i915/gt: Make timeslicing an explicit engine propertyChris Wilson
In order to allow userspace to rely on timeslicing to reorder their batches, we must support preemption of those user batches. Declare timeslicing as an explicit property that is a combination of having the kernel support and HW support.

2020-05-01drm/amdgpu: Changed CU reservation golden settingsOak Zeng
With previous golden settings, compute task can't use reserved LDS (32K) on CU0 and CU1. On 64K LDS system, if compute work group allocate more than 32K LDS, then it can't be dispatched to CU0 and CU1 because of the reservation. This enables compute task to use reserved LDS on CU0 and CU1.
