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. So it went from: ~$ sudo more /sys/kernel/debug/dri/0/i915_edp_psr_status Sink_Support: yes PSR mode: PSR1 Enabled: yes Busy frontbuffer bits: 0x000 Main link in standby mode: no HW Enabled & Active bit: yes Source PSR status: 0x24050006 [SRDONACK] To: ~$ sudo more /sys/kernel/debug/dri/0/i915_edp_psr_status Sink support: yes [0x03] PSR mode: PSR1 enabled Source PSR ctl: enabled [0x81f00e26] Source PSR status: IDLE [0x04010006] Busy frontbuffer bits: 0x00000000 The 'Main link in standby mode' was removed as it is not useful but if needed by someone the information is still in the register value of 'Source PSR ctl' inside of the brackets, PSR mode and Enabled was squashed into PSR mode, some renames and reorders and we have this cleaner version. This will also make easy to parse debugfs for IGT tests. v2: Printing sink PSR version with only 2 hex digits as it is a byte Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Cc: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com> Suggested-by:

For now PSR2 is still disabled by default for all platforms but is our intention to let debugfs to enable it for debug and tests proporses, so intel_psr2_enabled() that is also used by debugfs to decide if PSR2 is going to be enabled needs to take in consideration the debug field. v2: Using the switch/case that intel_psr2_enabled() already had to handle this(DK) Cc: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Reviewed-by:

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:

Since commit d4ccceb0 ("drm/i915/icl: Ringbuffer interrupt handling") we have required a mechanism to avoid touching the interrupt hardware for breadcrumbs, superseding our mock interface for selftests. The residual problem (ideas welcome) is in probing the mock ring registers for ring_is_idle. Hmm, maybe we should just install mock handlers for i915->uncore.mmio__write and friends? Only problem being is that we would to truly mock some expected reads. :( References: d4ccceb0 ("drm/i915/icl: Ringbuffer interrupt handling") Signed-off-by:

The motivation for introducing the check that we only enable breadcrumb irqs if the device's irq was installed was once upon a time we waited during suspend after disabling interrupts (which was quite slow until the bug was discovered). Since then we have the notion of pinning the breadcrumb irq, broadening it from the sole purpose of user interrupt notification and waiting, and more importantly decoupling it from a very defined time period during which enabling the irq was expected. So stop insisting the irq is installed before we setup our IMR masks, if the IER isn't yet enabled, nothing will happen and we will timeout instead, revealing the lack of irq in the hang debug messages.
