According to BSpec the Data Island Packet should be disabled after disabling the transcoder, but before the transcoder clock select is set to none. On an ICL RVP, daisy-chained MST config not following this leads to a hang with the following MCE when disabling the output: [ 870.948739] mce: [Hardware Error]: CPU 0: Machine Check Exception: 5 Bank 6: ba00000011000402 [ 871.019212] mce: [Hardware Error]: RIP !INEXACT! 10:<ffffffff81aca652> {poll_idle+0x92/0xb0} [ 871.019212] mce: [Hardware Error]: TSC 135a261fe61 [ 871.019212] mce: [Hardware Error]: PROCESSOR 0:706e5 TIME 1591739604 SOCKET 0 APIC 0 microcode 20 [ 871.019212] mce: [Hardware Error]: Run the above through 'mcelog --ascii' [ 871.019212] mce: [Hardware Error]: Machine check: Processor context corrupt [ 871.019212] Kernel panic - not syncing: Fatal machine check [ 871.019212] Kernel Offset: disabled Bspec: 4287 Fixes: fa37a213 ("drm/i915: Stop sending DP SDPs on ddi disable") Cc: Gwan-gyeong Mun <gwan-gyeong.mun@intel.com> Cc: Uma Shankar <uma.shankar@intel.com> Signed-off-by:

We have a test case to exercise resetting an engine while the other engines are busy, all the TEST_SELF adds on top is that the target engine also has background activity. In this case it is useful to first test resetting the engine while there is background activity, as a separate flag from exercising all others. Signed-off-by:

In commit 5ba32c7b ("drm/i915/execlists: Always force a context reload when rewinding RING_TAIL"), we placed the check for rewinding a context on actually submitting the next request in that context. This was so that we only had to check once, and could do so with precision avoiding as many forced restores as possible. For example, to ensure that we can resubmit the same request a couple of times, we include a small wa_tail such that on the next submission, the ring->tail will appear to move forwards when resubmitting the same request. This is very common as it will happen for every lite-restore to fill the second port after a context switch. However, intel_ring_direction() is limited in precision to movements of upto half the ring size. The consequence being that if we tried to unwind many requests, we could exceed half the ring and flip the sense of the direction, so missing a force restore. As no request can be greater than half the ring (i.e. 2048 bytes in the smallest case), we can check for rollback incrementally. As we check against the tail that would be submitted, we do not lose any sensitivity and allow lite restores for the simple case. We still need to double check upon submitting the context, to allow for multiple preemptions and resubmissions.

Rocket Lake uses the same 'abox0' mechanism to handle pixel data transfers from memory that gen11 platforms used, rather than the abox1/abox2 interfaces used by TGL/DG1. For the most part this is a hardware implementation detail that's transparent to driver software, but we do have to program a couple of tuning registers (MBUS_ABOX_CTL and BW_BUDDY registers) according to which ABOX instances are used by a platform. Let's track the platform's ABOX usage in the device info structure and use that to determine which instances of these registers to program. As an exception to this rule is that even though TGL/DG1 use ABOX1+ABOX2 for data transfers, we're still directed to program the ABOX_CTL register for ABOX0; so we'll handle that as a special case. v2: - Store the mask of platform-specific abox registers in the device info structure. - Add a TLB_REQ_TIMER() helper macro. (Aditya) v3: - Squash ABOX and BW_BUDDY patches together and use a single mask for both of them, plus a special-case for programming the ABOX0 instance on all gen12.

As a last minute addition, I added an assertion to make sure that the new i915_vma view would be equal to the discard. However, the positive encouragement from CI only goes to show that we rarely take this path, and it wasn't until the post-merge run did we hit the assert -- because it compared the wrong view.

Across the many users of the GGTT vma (internal objects, mmapings, display etc), we may end up with conflicting requirements for the placement. Currently, we try to resolve the conflict by unbinding the vma and rebinding it to match the new constraints; over time we will end up with a GGTT that matches the most strict constraints over all concurrent users. However, this causes a problem if the vma is currently in use as we must wait until it is idle before moving it. But there is no restriction on the number of views we may use (apart from the limited size of the GGTT itself), and so if the active vma does not meet our requirements, try and build a new one!

Reduce the 3 relocation paths down to the single path that accommodates all. The primary motivation for this is to guard the relocations with a natural fence (derived from the i915_request used to write the relocation from the GPU). The tradeoff in using async gpu relocations is that it increases latency over using direct CPU relocations, for the cases where the target is idle and accessible by the CPU. The benefit is greatly reduced lock contention and improved concurrency by pipelining. Note that forcing the async gpu relocations does reveal a few issues they have. Firstly, is that they are visible as writes to gem_busy, causing to mark some buffers are being to written to by the GPU even though userspace only reads. Secondly is that, in combination with the cmdparser, they can cause priority inversions. This should be the case where the work is being put into a common workqueue losing our priority information and so being executed in FIFO from the worker, denying us the opportunity to reorder the requests afterwards.

RKL uses the DDI A, DDI B, DDI USBC1, DDI USBC2 from the DE point of view, so all DDI/pipe/transcoder register use these indexes to refer to them. Combo phy and IO functions follow another namespace that we keep as "enum phy". The VBT in theory would use the DE point of view, but that does not happen in practice.

Although we properly captured RKL's three pipes in the device info structure, we forgot to make the corresponding update to the transcoder mask. Set this field so that our transcoder loops will operate properly. Fixes: 123f62de ("drm/i915/rkl: Add RKL platform info and PCI ids") Signed-off-by:

Sometimes an engine might need to keep forcewake active while it is busy submitting requests for a particular workaround. Track such nuisance with engine->fw_domain. Signed-off-by:

Use the plain msec_to_jiffies() rather than the _timeout variant so we round down and do not add an extra jiffy to our interval. For example, with timeslicing we do not want to err on the longer side as any fairness depends on catching hogging contexts on the GPU. Bring on CFS. Signed-off-by:

If the execbuf is interrupted after building the cmdparser pipeline, and before we commit to submitting the request to HW, we would attempt to clean up the cmdparser early. While we held active references to the vma being parsed and constructed, we did not hold an active reference for the buffer pool itself. The result was that an interrupted execbuf could still have run the cmdparser pipeline, but since the buffer pool was idle, its target vma could have been recycled. Note this problem only occurs if the cmdparser is running async due to pipelined waits on busy fences, and the execbuf is interrupted. Fixes: 686c7c35 ("drm/i915/gem: Asynchronous cmdparser") Fixes: 16e87459 ("drm/i915/gt: Move the batch buffer pool from the engine to the gt") Signed-off-by:

The DP spec says: "When the combination of the requested pre-emphasis level and voltage swing exceeds the capability of a DPTX, the DPTX shall set the pre-emphasis level according to the request and use the highest voltage swing it can output with the given pre-emphasis level." and "When a DPTX reads a request beyond the limits of this Standard, the DPTX shall set the pre-emphasis level according to the request and set the highest voltage swing level it can output with the given pre-emphasis level. If a DPTX is requested for 9.5dB of pre-emphasis level (may be supported for a DPTX) and cannot support that level, it shall set the pre-emphasis level to the next highest level, 6dB." Ie. we should first validate the pre-emphasis, and then select the appropriate vswing for it. Signed-off-by:
