The current algorithm to read out devcoredump is O(N*N) where N is the size of coredump due to usage of the drm_coredump_printer in xe_devcoredump_read. Switch to a O(N) algorithm which prints the devcoredump into a readable format in snapshot work and update xe_devcoredump_read to memcpy from the readable format directly. v2: - Fix double free on devcoredump removal (Testing) - Set read_data_size after snap work flush - Adjust remaining in iterator upon realloc (Testing) - Set read_data upon realloc (Testing) v3: - Kernel doc v4: - Two pass algorithm to determine size (Maarten) v5: - Use scope for reading variables (Johnathan) Reported-by:

We want to determine the size of the devcoredump before writing it out. To that end, we will run the devcoredump printer with NULL data to get the size, alloc data based on the generated offset, then run the devcorecump again with a valid data pointer to print. This necessitates not writing data to the data pointer on the initial pass, when it is NULL. v5: - Better commit message (Jonathan) - Add kerenl doc with examples (Jani) Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Acked-by:

Enable feature to allow memory reads to take a priority memory path. This will reduce latency on the read path, but may introduce read after write (RAW) hazards as read and writes will no longer be ordered. To avoid RAW hazards, SW can use the MI_MEM_FENCE command or any other MI command that generates non posted memory writes. This will ensure data is coherent in memory prior to execution of commands which read data from memory. RCS,BCS and CCS support this feature. No pattern identified in KMD that could lead to a hazard. v2: Modify commit message, enable priority mem read feature for media, modify version range, modify bspec detail (Matt Roper) v3: Rebase, fix cramped line-wrapping (jcavitt) v4: Rebase v5: Media does not support Priority Mem Read.

Now that rtp has OR rules, it's not needed to extend it to process OOB WAs. Previously if an entry had no name, it was considered as "a set of rules OR'ed with the last named entry". Instead of generating new entries, add OR rules. The syntax for xe_wa_oob.rules remains the same, with xe_gen_wa_oob generating the slightly different table. Object sizes delta are negligible, but having just one logic makes it easier to maintain: add/remove: 0/0 grow/shrink: 1/2 up/down: 160/-269 (-109) Function old new delta __compound_literal 6104 6264 +160 xe_wa_dump 1839 1810 -29 oob_was 816 576 -240 Total: Before=17257, After=17148, chg -0.63% Reviewed-by:

Like commit 512660cd ("drm/xe/rtp: Expand max rules/actions per entry") did, expand the maximum number of actions/rules. That commit was too conservative, just incrementing 2. Other than the ugliness of these macros and additional preprocessor steps when they are used, there are no downsides on increasing the maximum: the tables in which they are used use a sentinel to mark the last element. With rtp processing now supporting OR rules, it's possible to migrate the extension made for OOB WAs that "entries with name are OR'ed in previous entry". For that the maximum number of rules needs to be increased. Just double it. Hopefully 12 is sufficient for longer than 6 was. Reviewed-by:

Stop doing the calculation both in rtp_mark_active() and in its caller. The caller easily knows the number of entries to mark, so just pass it forward. That also simplifies rtp_mark_active() since now it doesn't have a special case when handling 1 entry. Reviewed-by:

Lucas De Marchi authored
The OOB WAs use xe_rtp_process(), without passing an sr to save result of the actions since there are none. They are also executed in a gt-only context, making it harder to share the implementation. Thus, introduce a new set of tests to check these RTP entries. The only check that can be done is if the entry was marked as active. Before commit fd6797ec ("drm/xe/rtp: Fix off-by-one when processing rules") several of these tests were failing: the processing of OR'ed entries would make the subsequent entry to be inadvertently enabled.

Although all current Xe2 platforms support FlatCCS, we probably shouldn't assume that will be universally true forever. In the past we've had platforms like PVC that didn't support compression, and the same could show up again at some point in the future. Future-proof the migration code by adding an explicit check for FlatCCS support to the condition that decides whether to use a compressed PAT index for migration. While we're at it, we can drop the IS_DGFX check since it's redundant with the src_is_vram check (only dGPUs have VRAM).

Gustavo noticed an odd "+ 2" in rtp_mark_active() while processing rtp rules and pointed that it should be "+ 1". In fact, while processing entries without actions (OOB workarounds), if the WA is activated and has OR rules, it will also inadvertently activate the very next workaround. Test in a LNL B0 platform by moving 18024947630 on top of 16020292621, makes the latter become active: $ cat /sys/kernel/debug/dri/0/gt0/workarounds ...

eu_type_to_str() relies on -Wswitch to warn (and -Werror) to make sure it handles all enum values. However it's perfectly legal to pass an int to that function so in the end that function may happen to return nothing. There's too much implicit knowledge about the initialization of eu_type for a compiler to notice eu_type is never assigned to anything other than those values. Trying to reproduce this issue, none of gcc-9, gcc-10 and gcc-13 triggered for me, but this was reported in a different system with gcc-10: drivers/gpu/drm/xe/xe.o: warning: objtool: xe_gt_topology_dump() falls through to next function xe_gt_topology_init() Also it was reported these warnings when building with clang: drivers/gpu/drm/xe/xe.o: warning: objtool: xe_gt_topology_dump+0x77: sibling call from callable instruction with modified stack frame drivers/gpu/drm/xe/xe.o: warning: objtool: xe_gt_topology_dump() falls through to next function xe_dss_mask_group_ffs() drivers/gpu/drm/xe/xe.o: warning: objtool: xe_gt_topology_dump+0x77: can't find jump dest instruction at .text.xe_gt_topology_dump+0xc0 Since that value is not really possible in real world, just take the simple approach and return NULL.
