Reports live state of PSR2 form PSR2_STATUS register. bit field 31:28 gives the live state of PSR2. It can be used to check if system is in deep sleep, selective update or selective update standby. During video play back, we can use this to check if system is entering SU mode or not. when system is in idle state, DEEP_SLEEP(8) must be entered. When video playback is happening, system must be in SLEEP(3 / selective update) or SU_STANDBY( 6 / selective update standby) v2: (Rodrigo) - Remove EDP_PSR2_STATUS_TG_ON=a ,instead use ARRAY_SIZE Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Cc: Jim Bride <jim.bride@linux.intel.com> Signed-off-by:

Psr1 and psr2 are mutually exclusive,ie when psr2 is enabled, psr1 should be disabled.When psr2 is exited , bit 31 of reg PSR2_CTL must be set to 0 but currently bit 31 of SRD_CTL (psr1 control register)is set to 0. Also ,PSR2_IDLE state is looked up from SRD_STATUS(psr1 register) instead of PSR2_STATUS register, which has wrong data, resulting in blankscreen. hsw_enable_source is split into hsw_enable_source_psr1 and hsw_enable_source_psr2 for easier code review and maintenance, as suggested by rodrigo and jim. v2: (Rodrigo) - Rename hsw_enable_source_psr* to intel_enable_source_psr* v3: (Rodrigo) - In hsw_psr_disable , 1) for psr active case, handle psr2 followed by psr1. 2) psr inactive case, handle psr2 followed by psr1 v4:(Rodrigo) - move psr2 restriction(32X20) to match_conditions function returning false and fully blocking PSR to a new patch before this one. v5: in source_psr2, removed val = EDP_PSR_ENABLE Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Cc: Jim Bride <jim.bride@linux.intel.com> Signed-off-by:

The WaDisableLSQCROPERFforOCL workaround has the side effect of disabling an L3SQ optimization that has huge performance implications and is unlikely to be necessary for the correct functioning of usual graphic workloads. Userspace is free to re-enable the workaround on demand, and is generally in a better position to determine whether the workaround is necessary than the DRM is (e.g. only during the execution of compute kernels that rely on both L3 fences and HDC R/W requests). The same workaround seems to apply to BDW (at least to production stepping G1) and SKL as well (the internal workaround database claims that it does for all steppings, while the BSpec workaround table only mentions pre-production steppings), but the DRM doesn't do anything beyond whitelisting the L3SQCREG4 register so userspace can enable it when it sees fit. Do the same on KBL platforms. Improves performance of the GFXBench4 gl_manhattan31 benchmark by 60%, and gl_4 (AKA car chase) by 14% on a KBL GT2 running Mesa master -- This is followed by a regression of 35% and 10% respectively for the same benchmarks and platform caused by my recent patch series switching userspace to use the dataport constant cache instead of the sampler to implement uniform pull constant loads, which caused us to hit more heavily the L3 cache (and on platforms other than KBL had the opposite effect of improving performance of the same two benchmarks). The overall effect on KBL of this change combined with the recent userspace change is respectively 4.6% and 2.6%. SynMark2 OglShMapPcf was affected by the constant cache changes (though it improved as it did on other platforms rather than regressing), but is not significantly affected by this patch (with statistical significance of 5% and sample size 20). v2: Drop some more code to avoid unused variable warning.

This patch adds the DP MST audio support on i915 platform and it will enable dyn_pcm_assign feature. DP MST supports several device entry on the same port and each device entry can map to one pcm stream. For example, on i915, there are 3 pins, and each pin has 3 device entries. This means there should be 3x3 pcms. However, there is only 3 pipe lines in i915. This means 3 pcms are actived at most at the same moment. We will create 5 pcms (pin number + dev entry num - 1) in this case. For the details, please refer commit a76056f2 ("ALSA: hda - hdmi dynamically bind PCM to pin when monitor hotplug") Each device entry is a virtual pin. It is described by pin_nid and dev_id in struct hdmi_spec_per_pin. Reviewed-by:

The vma->exec_list is still the only means we have for both reserving an object in execbuf, and for constructing the eviction list. So during the construction of the eviction list, we must treat anything already on the exec_list as being pinned. Yes, this sharing of two semantically different lists will be fixed! But in the meantime, we have the issue that this is tripping up CI since we started using i915_gem_gtt_reserve_node() + i915_gem_evict_for_node() from the regular execbuf reservation path in commit 606fec95 ("drm/i915: Prefer random replacement before eviction search"): [ 108.424063] kernel BUG at drivers/gpu/drm/i915/i915_vma.h:254!

It is an error to start a new request on the same timeline (ringbuffer) as the current one before the current is submitted. If there are two requests emitting to the ringbuffer at the same time, the operation is undefined. We can catch this by checking for the timeline having a later seqno than ours when we come to submit our request. Currently we have this check at the end of __i915_add_request, but having an early check as well isolates a failure in the caller versus a failure in sealing the request (i.e. from inside __i915_add_request itself).

Performing an eviction search can be very, very slow especially for a range restricted replacement. For example, a workload like gem_concurrent_blit will populate the entire GTT and then cause aperture thrashing. Since the GTT is a mix of active and inactive tiny objects, we have to search through almost 400k objects before finding anything inside the mappable region, and as this search is required before every operation performance falls off a cliff. Instead of performing the full search, we do a trial replacement of the node at a random location fitting the specified restrictions. We lose the strict LRU property of the GTT in exchange for avoiding the slow search (several orders of runtime improvement for gem_concurrent_blit 4KiB-global-gtt, e.g. from 5000s to 20s). The loss of LRU replacement is (later) mitigated firstly by only doing replacement if we find no freespace and secondly by execbuf doing a PIN_NONBLOCK search first before it starts thrashing (i.e. the random replacement will only occur from the already inactive set of objects). v2: Ascii-art, and check preconditionst v3: Rephrase final sentence in comment to explain why we don't bother with if (i915_is_ggtt(vm)) for preferring random replacement.

When we evict from the GTT to make room for an object, the hole we create is put onto the MRU stack inside the drm_mm range manager. On the next search pass, we can speed up a PIN_HIGH allocation by referencing that stack for the new hole. v2: Pull together the 3 identical implements (ahem, a couple were outdated) into a common routine for allocating a node and evicting as necessary. v3: Detect invalid calls to i915_gem_gtt_insert() v4: kerneldoc Signed-off-by:

PSR2 vsc revision number hb2( as per table 6-11)is updated to 4 or 5 based on Y cordinate and Colorimetry Format as below 04h = 3D stereo + PSR/PSR2 + Y-coordinate. 05h = -3D stereo- + PSR/PSR2 + Y-coordinate + Pixel Encoding/Colorimetry Format indication. A DP Source device is allowed to indicate the pixel encoding/colorimetry format to the DP Sink device with VSC SDP only when the DP Sink device supports it ( i.e.,VSC_SDP_EXTENSION_FOR_COLORIMETRY_SUPPORTED bit in the DPRX_FEATURE_ENUMERATION_LIST register (DPCD Address 02210h, bit 3; is set to 1). v2: (Jani) - Change DP_PSR_Y_COORDINATE to DP_PSR2_SU_Y_COORDINATE_REQUIRED. - Add DP_PSR2_SU_GRANULARITY_REQUIRED. - Change DPRX_FEATURE_ENUMERATION_LIST to DP_DPRX. - Add GTC_CAP and AV_SYNC_CAP, other bits in DPRX_FEATURE_ENUMERATION_LIST. v3: (Jani) - Add support for bits 7:4 and 1 as per DP v1.4 for DPRX_FEATURE_ENUMERATION_LIST.

Start converting over from the byte count to its semantic macro, either we want to allocate the size of a physical page in main memory or we want the size of a virtual page in the GTT. 4096 could mean either, but PAGE_SIZE and I915_GTT_PAGE_SIZE are explicit and should help improve code comprehension and future changes. In the future, we may want to use variable GTT page sizes and so have the challenge of knowing which hardcoded values were used to represent a physical page vs the virtual page. v2: Look for a few more 4096s to convert, discover IS_ALIGNED(). v3: 4096ul paranoia, make fence alignment a distinct value of 4096, keep bdw stolen w/a as 4096 until we know better. v4: Add asserts that i915_vma_insert() start/end are aligned to GTT page sizes.

It has been some time since i915_gem_engine_cleanup was only called from the module unload path, and now it is only called when the GPU is wedged. Mika complained that the name is confusing, especially in light of the existence of i915_gem_cleanup_engines(). Signed-off-by:

Similarly to a normal reset, after we mark the GPU as wedged (completely fubar and no more requests can be executed), set the error status on all the in flight requests. Signed-off-by:

Let userspace know if its request was resubmitted due to it being executed at the time of a global reset. In this case, the reset was for a guilty request on another engine, and this request was an innocent victim that will be re-executed upon restarting. However, since it was running at the time of the reset, we can not guarantee that it suffered no ill-effects from the reset (e.g. some context state may be lost, or some self-modifying fragment shaders will be restarted from the final state not their initial state), to let userspace know that it has been corrupted set a special value on the fence->error, -EAGAIN. If the request does hang on resubmission, the error will be overwritten with -EIO. Signed-off-by:

The struct dma_fence carries a status field exposed to userspace by sync_file. This is inspected after the fence is signaled and can convey whether or not the request completed successfully, or in our case if we detected a hang during the request (signaled via -EIO in SYNC_IOC_FILE_INFO). v2: Mark all cancelled requests as failed.

Always reset the requests of the guilty context, including the hung request that we tell the hardware to skip. This should help if the reprogram fails entirely, but more importantly makes the guilty path more uniform (and simplifies the subsequent patch to tweak the cancelled requests). Signed-off-by:

The core provides now an ABI to userspace for generation of frame CRCs, so implement the ->set_crc_source() callback and reuse as much code as possible with the previous ABI implementation. When handling the pageflip interrupt, we skip 1 or 2 frames depending on the HW because they contain wrong values. For the legacy ABI for generating frame CRCs, this was done in userspace but now that we have a generic ABI it's better if it's not exposed by the kernel. v2: - Leave the legacy implementation in place as the ABI implementation in the core is incompatible with it. v3: - Use the "cooked" vblank counter so we have a whole 32 bits. - Make sure we don't mess with the state of the legacy CRC capture ABI implementation. v4: - Keep use of get_vblank_counter as in the legacy code, will be changed in a followup commit. v5: - Skip first frame or two as it's known that they contain wrong data. - A few fixes suggested by Emil Velikov. v6: - Rework programming of the HW registers to preserve previous behavior. v7: - Address whitespace issue. - Added a comment on why in the implementation of the new ABI we skip the 1st or 2nd frames. v9: - Add stub for intel_crtc_set_crc_source. v12: - Rebased. - Remove stub for intel_crtc_set_crc_source and instead set the callback to NULL (Jani Nikula). v15: - Rebased.
