While we do have GT oriented print macros, add few more GuC specific to have common look and feel across all messages related to the GuC and to avoid chasing the gt pointer. We will use these macros shortly in upcoming patches. Signed-off-by:

The GuC specific register state entry in the error capture object was just called 'capture'. Although the companion 'node' entry was called 'guc_capture_node'. Rename the base entry to be 'guc_capture' instead so that it is a) more consistent and b) more obvious what it is. Signed-off-by:

For understanding bug reports, it can be useful to have an explicit dmesg print when a reset notification is received from GuC. As opposed to simply inferring that this happened from other messages. Signed-off-by:

Engine resets are supposed to never fail. But in the case when one does (due to unknown reasons that normally come down to a missing w/a), it is useful to get as much information out of the system as possible. Given that the GuC intentionally dies on such a situation, it is not possible to get a guilty context notification back. So do a manual search instead. Given that GuC is dead, this is safe because GuC won't be changing the engine state asynchronously. v2: Change comment to be less alarming (Tvrtko) Signed-off-by:

A hang situation has been observed where the only requests on the context were either completed or not yet started according to the breaadcrumbs. However, the register state claimed a batch was (maybe) in progress. So, allow capture of the pending request on the grounds that this might be better than nothing. v2: Reword 'not started' warning message (Tvrtko) Signed-off-by:

There was a report of error captures occurring without any hung context being indicated despite the capture being initiated by a 'hung context notification' from GuC. The problem was not reproducible. However, it is possible to happen if the context in question has no active requests. For example, if the hang was in the context switch itself then the breadcrumb write would have occurred and the KMD would see an idle context. In the interests of attempting to provide as much information as possible about a hang, it seems wise to include the engine info regardless of whether a request was found or not. As opposed to just prentending there was no hang at all. So update the error capture code to always record engine information if a context is given. Which means updating record_context() to take a context instead of a request (which it only ever used to find the context anyway). And split the request agnostic parts of intel_engine_coredump_add_request() out into a seaprate function. v2: Remove a duplicate 'if' statement (Umesh) and fix a put of a null pointer. v3: Tidy up request locking code flow (Tvrtko) v4: Pull in improved info message from next patch and fix up potential leak of GuC register state (Daniele) Signed-off-by:

The debugfs dump of requests was confused about what state requires the execlist lock versus the GuC lock. There was also a bunch of duplicated messy code between it and the error capture code. So refactor the hung request search into a re-usable function. And reduce the span of the execlist state lock to only the execlist specific code paths. In order to do that, also move the report of hold count (which is an execlist only concept) from the top level dump function to the lower level execlist specific function. Also, move the execlist specific code into the execlist source file. v2: Rename some functions and move to more appropriate files (Daniele). v3: Rename new execlist dump function (Daniele) Fixes: dc0dad36 ("drm/i915/guc: Fix for error capture after full GPU reset with GuC") Signed-off-by:

When GuC support was added to error capture, the reference counting around the request object was broken. Fix it up. The context based search manages the spinlocking around the search internally. So it needs to grab the reference count internally as well. The execlist only request based search relies on external locking, so it needs an external reference count but within the spinlock not outside it. The only other caller of the context based search is the code for dumping engine state to debugfs. That code wasn't previously getting an explicit reference at all as it does everything while holding the execlist specific spinlock. So, that needs updaing as well as that spinlock doesn't help when using GuC submission. Rather than trying to conditionally get/put depending on submission model, just change it to always do the get/put. v2: Explicitly document adding an extra blank line in some dense code (Andy Shevchenko). Fix multiple potential null pointer derefs in case of no request found (some spotted by Tvrtko, but there was more!). Also fix a leaked request in case of !started and another in __guc_reset_context now that intel_context_find_active_request is actually reference counting the returned request. v3: Add a _get suffix to intel_context_find_active_request now that it grabs a reference (Daniele). v4: Split the intel_guc_find_hung_context change to a separate patch and rename intel_context_find_active_request_get to intel_context_get_active_request (Tvrtko). v5: s/locking/reference counting/ in commit message (Tvrtko) Fixes: dc0dad36 ("drm/i915/guc: Fix for error capture after full GPU reset with GuC") Fixes: 573ba126 ("drm/i915/guc: Capture error state on context reset") Signed-off-by:

GAMSTLB_CTRL and GAMCNTRL_CTRL became multicast/replicated registers on Xe_HP. They should be defined accordingly and use MCR-aware operations. These registers have only been used for some dg2/xehpsdv workarounds, so this fix is mostly just for consistency/future-proofing; even lacking the MCR annotation, workarounds will always be properly applied in a multicast manner on these platforms.

Workaround Wa_18018781329 has applied to several recent Xe_HP-based platforms. However there are some extra gotchas to implementing this properly for MTL that we need to take into account: * Due to the separation of media and render/compute into separate GTs, this workaround needs to be implemented on each GT, not just the primary GT. Since each class of register only exists on one of the two GTs, we should program the appropriate registers on each GT. * As with past Xe_HP platforms, the registers on the primary GT (Xe_LPG IP) are multicast/replicated registers and should be handled with the MCR-aware functions. However the registers on the media GT (Xe_LPM+ IP) are regular singleton registers and should _not_ use MCR handling. We need to create separate register definitions for the Xe_HP multicast form and the Xe_LPM+ singleton form and use each in the appropriate place. * Starting with MTL, workarounds documented by the hardware teams are technically associated with IP versions/steppings rather than top-level platforms. That means we should take care to check the media IP version rather than the graphics IP version when deciding whether the workaround is needed on the Xe_LPM+ media GT (in this case the workaround applies to both IPs and the stepping bounds are identical, but we should still write the code appropriately to set a proper precedent for future workaround implementations). * It's worth noting that the GSC register and the CCS register are defined with the same MMIO offset (0xCF30). Since the CCS is only relevant to the primary GT and the GSC is only relevant to the media GT there isn't actually a clash here (the media GT automatically adds the additional 0x380000 GSI offset). However there's currently a glitch in the bspec where the CCS register doesn't show up at all and the GSC register is listed as existing on both GTs. That's a known documentation problem for several registers with shared GSC/CCS offsets; rest assured that the CCS register really does still exist.

Register reset characteristics (i.e., whether the register maintains or loses its value on engine reset) is an important factor that determines which wa_list we want to add workarounds to. We recently found out that the bspec documentation for the Xe_HP's "GAM" registers in the 0xC800 - 0xCFFF range was misleading; these registers do not actually lose their value on engine resets as the documentation implied. This means there's no need to re-apply workarounds touching these registers after a reset, and the corresponding workarounds should be moved from the 'engine' lists back to the 'gt' list. v2: - Don't add Wa_18018781329 to xehpsdv; the original condition didn't include that platform. (Gustavo) - Move the MTL code to the GT function as-is for now; we'll take care of the additional fixes needed in a follow-up patch.

That register became a multicast register as of Xe_HP and it is currently used only for DG2. Use a proper prefix since there could be usage of the same register for previous platforms in the future, which would require a different definition (i.e. using _MMIO). Note that, in its current state, the code does not cause functional problems, since the actual application of the workaround would implicitly use multicast mode. This fix is more toward consistency and being future-proof uses of this register outside of workarounds. v2: - Add paragraph noting that this change is for consistency and making the code future-proof.

The implementation of Wa_22011450934 introduced three new register definitions in i915_reg.h that didn't get moved to the GT/engine register headers when all the other registers moved; let's move them to the appropriate headers and tidy up their definitions now for consistency: - STATE_ACK_DEBUG is moved to the engine register header and converted to a parameterized definition; the workaround only needs the RCS instance to be programmed, but there are instances on other engines that could be used by other workarounds in the future. - The two CULLBIT registers move to the GT register header. Since they belong to MMIO ranges that became MCR starting with Xe_HP, their definitions should be defined as MCR_REG() and use an Xe_HP prefix to keep the register semantics clear. Note that the MCR definition is just for consistency and to prevent accidental misuse if other workarounds related to these registers show up in the future. There's no functional change to today's driver since the workaround that references these registers only accesses them via MI_LRR engine instructions. Engine-initiated register accesses do not utilize the same steering controls as CPU-initiated accesses; they use a different steering control register (0x20CC) which is initialized to a non-terminated DSS target by pre-OS firmware and never changed thereafter (i915 does not touch it and userspace does not have permission to change that register).

If PXP arb-session is being attempted on older hardware SKUs or on hardware with older, unsupported, firmware versions, then don't report the failure with a drm_error. Instead, look specifically for the API-version error reply and drm_dbg that reply. In this case, the user-space will eventually get a -ENODEV for the protected context creation which is the correct behavior and we don't create unnecessary drm_error's in our dmesg (for what is unsupported platforms). Changes from prio revs: v2 : - remove unnecessary newline. (Jani) v1 : - print incorrect version from input packet, not output. Signed-off-by:

With commit 359c6649 ("drm/gem: Implement shadow-plane {begin, end}_fb_access with vmap"), the behavior of the shadow-plane helpers changed and the vunmap is now performed at the end of the current pageflip, instead of the end of the following pageflip. By performing the vunmap at the end of the current pageflip, invalid memory is accessed by the vkms during the plane composition, as the data is being unmapped before being used, as reported by the following warning: [ 275.866047] BUG: unable to handle page fault for address: ffffb382814e8002 [ 275.866055] #PF: supervisor read access in kernel mode [ 275.866058] #PF: error_code(0x0000) - not-present page [ 275.866061] PGD 1000067 P4D 1000067 PUD 110a067 PMD 46e3067 PTE 0 [ 275.866066] Oops: 0000 [#1] PREEMPT SMP PTI [ 275.866070] CPU: 2 PID: 49 Comm: kworker/u8:2 Not tainted 6.1.0-rc6-00018-gb357e7ac-dirty #54 [ 275.866074] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.16.1-2.fc37 04/01/2014 [ 275.866076] Workqueue: vkms_composer vkms_composer_worker [vkms] [ 275.866084] RIP: 0010:XRGB8888_to_argb_u16+0x5c/0xa0 [vkms] [ 275.866092] Code: bf 56 0a 0f af 56 70 48 8b 76 28 01 ca 49 83 f8 02 41 b9 01 00 00 00 4d 0f 43 c8 48 01 f2 48 83 c2 02 31 f6 66 c7 04 f0 ff ff <0f> b6 0c b2 89 cf c1 e7 08 09 cf 66 89 7c f0 02 0f b6 4c b2 ff 89 [ 275.866095] RSP: 0018:ffffb382801b7db0 EFLAGS: 00010246 [ 275.866098] RAX: ffff896336ace000 RBX: ffff896310e293c0 RCX: 0000000000000000 [ 275.866101] RDX: ffffb382814e8002 RSI: 0000000000000000 RDI: ffffb382801b7de8 [ 275.866103] RBP: 0000000000001400 R08: 0000000000000280 R09: 0000000000000280 [ 275.866105] R10: 0000000000000010 R11: ffffffffc011d990 R12: ffff896302a1ece0 [ 275.866107] R13: 0000000000000000 R14: 0000000000000000 R15: 0000000080008001 [ 275.866109] FS: 0000000000000000(0000) GS:ffff89637dd00000(0000) knlGS:0000000000000000 [ 275.866112] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 275.866114] CR2: ffffb382814e8002 CR3: 0000000003bb4000 CR4: 00000000000006e0 [ 275.866120] Call Trace: [ 275.866123] <TASK> [ 275.866124] compose_active_planes+0x1c4/0x380 [vkms] [ 275.866132] vkms_composer_worker+0x9f/0x130 [vkms] [ 275.866139] process_one_work+0x1c0/0x370 [ 275.866160] worker_thread+0x221/0x410 [ 275.866164] ? worker_clr_flags+0x50/0x50 [ 275.866167] kthread+0xe1/0x100 [ 275.866172] ? kthread_blkcg+0x30/0x30 [ 275.866176] ret_from_fork+0x22/0x30 [ 275.866181] </TASK> [ 275.866182] Modules linked in: vkms [ 275.866186] CR2: ffffb382814e8002 [ 275.866191] ---[ end trace 0000000000000000 ]--- Therefore, introduce again prepare_fb and cleanup_fb functions to the vkms, which were previously removed on commit b43e2ec0 ("drm/vkms: Let shadow-plane helpers prepare the plane's FB").

Since the DP/HDMI connector do not set connector->doublescan_allowed, the doublescan modes will get automatically filtered during drm_helper_probe_single_connector_modes(). Therefore check for double scan modes is not required and is dropped from modevalid functions for both DP and HDMI. Signed-off-by:

The documentation for struct drm_minor already states this, but that's not always that easy to find. Also due to historical reasons we still have the minor-centric interfaces (like drm_debugfs_create_files), but since this is now getting fixed we can put a few more pointers in place as to how this should be done ideally. Note that debugfs isn't there yet for all cases (debugfs files on kms objects like crtc/connector aren't supported, neither debugfs files with full fops), so the debugfs side of this is still rather aspirational and more for new users than converting everything existing. todo.rst covers the additional work needed already. Motivated by some discussion with Rodrigo on irc about how drm/xe should lay out its sysfs interfaces. v2: Make the debugfs situation clearer in the commit message, but don't elaborate more in the actual kerneldoc to avoid distracting from the main message around sysfs (Jani) Also fix some typos.

Use page aligned size to reserve memory usage because page aligned TTM BO size is used to unreserve memory usage, otherwise no page aligned size causes memory usage accounting unbalanced. Change vram_used definition type to int64_t to be able to trigger WARN_ONCE(adev && adev->kfd.vram_used < 0, "..."), to help debug the accounting issue with warning and backtrace. Signed-off-by:
