The VBT int_crt_support can't be trusted on earlier platforms, and is always set to true in intel_bios.c for pre-DDI and pre-VLV platforms. We can simplify the output setup by unconditionally calling intel_crt_init() for these platforms. Suggested-by:

With most platforms not having TV support, only call intel_tv_init() on platforms that might actually have TV, specifically gens 3 and 4. This puts intel_tv_init() more in line with the rest of the outputs, and makes it slightly easier for the uninitiated to figure out which platforms actually have what. Reviewed-by:

We currently program userspace-provided gamma and degamma LUT's into our hardware without really checking to see whether they satisfy our hardware's rules. We should try to catch tables that are invalid for our hardware early and reject the atomic transaction. All of our platforms that accept a degamma LUT expect that the entries in the LUT are always flat or increasing, never decreasing. Also, our GLK and ICL platforms only accept degamma tables with r=g=b entries; so we should also add the relevant checks for that in anticipation of degamma support landing for those platforms. v2: - Use new API (single check function with bitmask of tests to apply) - Call helper for our gamma table as well (with no additional tests specified) so that the table size will be validated. v3: - Don't call on the gamma table since the LUT size is already tested at property blob upload and we don't have any additional hardware constraints for that LUT. v4: - Apply equal color channel check on gen10 as well; the bspec has some strange tagging for CNL platforms, but this appears to apply there as well.

Some hardware may place additional restrictions on the gamma/degamma curves described by our LUT properties. E.g., that a gamma curve never decreases or that the red/green/blue channels of a LUT's entries must be equal. Let's add a helper function that drivers can use to test that a userspace-provided LUT is valid and doesn't violate hardware requirements. v2: - Combine into a single helper that just takes a bitmask of the tests to apply. (Brian Starkey) - Add additional check (always performed) that LUT property blob size is always a multiple of the LUT entry size. (stolen from ARM driver) v3: - Drop the LUT size check again since drm_atomic_replace_property_blob_from_id() already covers this for us. (Alexandru Gheorghe) v4: - Use an enum to describe possible test values rather than #define's; this is cleaner to provide kerneldoc for.

When reading GEN11_GT_INTR_DWx closely after enabling the interrupts in gen11_irq_postinstall, the returned value is garbage. This can cause other parts of the setup code (e.g. gen11_reset_one_iir) to think that there are interrupts to be cleared when there are none. The garbage value is only seen on the first read done after the enable, so this looks like a posting issue. Adding a posting read after enabling the interrupts does indeed fix the problem. Note that the posting read has been purposely added outside of gen11_master_intr_enable since the issue has only been observed when the full interrupt setup is performed.

The old debugfs fields was not following a naming partern and it was a bit confusing.

Before adding yet another copy of struct live_test and its handler, refactor the existing code into a common framework for live selftests. For many live selftests, we want to know if the GPU hung or otherwise misbehaved during the execution of the test (beyond any infraction in the behaviour under test), live_test provides this by comparing the GPU state before and after, alerting if it unexpectedly changed (e.g. the reset counter changed). It also ensures that the GPU is idle before and after the test, so that residual code running on the GPU is flushed before testing. Signed-off-by:

Some tests (e.g. igt_vma_pin1) presume that we have a completely clean GGTT so that it can probe boundaries without fear that something is already allocated there. However, the mock device is starting to get complicated and following similar rules to the live device, i.e. we can't guarantee that i915->ggtt remains clean, so create a temporary address_space equivalent to the mock ggtt for the purpose.

During review of commit 71fc448c ("drm/i915/selftests: Make evict tolerant of foreign objects"), Matthew mentioned it would be better if we explicitly tracked the objects we created. We have an obj->st_link hook for this purpose, so add the corresponding list of objects and reduce our loops to only consider our own list.

The display engine has 2 dithering enable bits which both need to be set for dithering to happen, 1 in the PIPECONF register which is taken care of by i9xx_set_pipeconf() and a second bit at the encoder level. The dsi code was not setting the encoder level dithering enable bit causing dithering to be disabled, this commit fixes this. Signed-off-by:

There are 3 problems with the dsi code's pipe_bpp handling for 6 bpc pixel-formats which this commit addresses: 1) It assumes that the pipe_bpp is the same as the bpp going over the dsi lanes. This assumption is not valid for MIPI_DSI_FMT_RGB666, where pipe_bpp should be 18 so that we do proper dithering but we actually send 24 bpp over the dsi lanes (MIPI_DSI_FMT_RGB666_PACKED sends 18 bpp). This assumption is enforced by an assert in *_dsi_get_pclk(). This assert triggers on the initial hw-state readback on BYT/CHT devices which use MIPI_DSI_FMT_RGB666, such as the Prowise PT301 tablet. PIPECONF is set to 6BPC / 18 bpp by the GOP, while mipi_dsi_pixel_format_to_bpp() returns 24. This commits switches the calculations in *_dsi_get_pclk() to use the bpp from mipi_dsi_pixel_format_to_bpp(intel_dsi->pixel_format) which returns the bpp going over the mipi lanes and drops the assert. 2) On BXT bxt_dsi_get_pipe_config() wrongly overrides the pipe_bpp which i9xx_get_pipe_config() reads from PIPECONF with the return value from mipi_dsi_pixel_format_to_bpp(). This avoids the assert from 1. but is wrong since the pipe is actually running at the value configured in PIPECONF. This commit drops the override of pipe_bpp from bxt_dsi_get_pipe_config(). 3) The dsi encoder's compute_config() never assigns a value to pipe_bpp, unlike most other encoders. Falling back on compute_baseline_pipe_bpp() which always picks 24. 24 is only correct for MIPI_DSI_FMT_RGB88 for the others we should use 18 bpp so that we correctly do 6bpc color dithering. This commit adds code to intel_dsi_compute_config() to properly set pipe_bpp based on intel_dsi->pixel_format. Signed-off-by:
