Assign contexts in parent-child relationship consecutive guc_ids. This is accomplished by partitioning guc_id space between ones that need to be consecutive (1/16 available guc_ids) and ones that do not (15/16 of available guc_ids). The consecutive search is implemented via the bitmap API. This is a precursor to the full GuC multi-lrc implementation but aligns to how GuC mutli-lrc interface is defined - guc_ids must be consecutive when using the GuC multi-lrc interface. v2: (Daniel Vetter) - Explicitly state why we assign consecutive guc_ids v3: (John Harrison) - Bring back in spin lock Signed-off-by: Matthew Brost <[email protected]> Reviewed-by: John Harrison <[email protected]> Signed-off-by: John Harrison <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]

2021-10-15drm/nouveau/fifo: Reinstate the correct engine bit programmingMarek Vasut1-1/+1
Commit 64f7c698bea9 ("drm/nouveau/fifo: add engine_id hook") replaced fifo/chang84.c g84_fifo_chan_engine() call with an indirect call of fifo/g84.c g84_fifo_engine_id(). The G84_FIFO_ENGN_* values returned from the later g84_fifo_engine_id() are incremented by 1 compared to the previous g84_fifo_chan_engine() return values. This is fine either way for most of the code, except this one line where an engine bit programmed into the hardware is derived from the return value. Decrement the return value accordingly, otherwise the wrong engine bit is programmed into the hardware and that leads to the following failure: nouveau 0000:01:00.0: gr: 00000030 [ILLEGAL_MTHD ILLEGAL_CLASS] ch 1 [003fbce000 DRM] subc 3 class 0000 mthd 085c data 00000420 On the following hardware: lspci -s 01:00.0 01:00.0 VGA compatible controller: NVIDIA Corporation GT216GLM [Quadro FX 880M] (rev a2) lspci -ns 01:00.0 01:00.0 0300: 10de:0a3c (rev a2) Fixes: 64f7c698bea9 ("drm/nouveau/fifo: add engine_id hook") Signed-off-by: Marek Vasut <[email protected]> Cc: <[email protected]> # 5.12+ Cc: Ben Skeggs <[email protected]> Cc: Karol Herbst <[email protected]> Cc: Lyude Paul <[email protected]> Reviewed-by: Karol Herbst <[email protected]> Reviewed-by: Ben Skeggs <[email protected]> Signed-off-by: Karol Herbst <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected] Signed-off-by: Dave Airlie <[email protected]>

Hyper-V supports a hardware cursor feature. It is not used by Linux VM, but the Hyper-V host still draws a point as an extra mouse pointer, which is unwanted, especially when Xorg is running. The hyperv_fb driver uses synthvid_send_ptr() to hide the unwanted pointer. When the hyperv_drm driver was developed, the function synthvid_send_ptr() was not copied from the hyperv_fb driver.

In commit e11f5bd8228f ("drm: Add support for DP 1.4 Compliance edid corruption test") the function connector_bad_edid() started assuming that the memory for the EDID passed to it was big enough to hold `edid[0x7e] + 1` blocks of data (1 extra for the base block). It completely ignored the fact that the function was passed `num_blocks` which indicated how much memory had been allocated for the EDID. Let's fix this by adding a bounds check. This is important for handling the case where there's an error in the first block of the EDID. In that case we will call connector_bad_edid() without having re-allocated memory based on `edid[0x7e]`.

2021-10-14drm/i915: rename intel_sideband.[ch] to intel_sbi.[ch]Jani Nikula5-29/+13
Now that intel_sideband.[ch] has been decluttered, it's pure lpt/wpt iosf sideband. Let's call it intel_sbi, following the function naming.

2021-10-14drm/i915: split out intel_pcode.[ch] to separate fileJani Nikula17-255/+277
The snb+ pcode mailbox code is not sideband, so split it out to a separate file. As can be seen from the #include changes, very few places use both sideband and pcode. Code movement only.

2021-10-14drm/i915/bios: gracefully disable dual eDP for nowJani Nikula1-0/+47
For the time being, neither the power sequencer nor the backlight code properly support two eDP panels simultaneously. While the software states will be independent, the same sets of registers will be used for both eDP panels, clobbering the hardware state and leading to errors. Gracefully disable dual eDP until proper support has been added.

The VLV/CHV sideband code is pretty distinct from the rest of the sideband code. Split it out to new vlv_sideband.[ch]. Pure code movement with relevant #include changes, and a tiny checkpatch fix on top.

2021-10-13drm/amdkfd: unregistered svm range not overlap with TTM rangePhilip Yang3-7/+94
When creating unregistered new svm range to recover retry fault, avoid new svm range to overlap with ranges or userptr ranges managed by TTM, otherwise svm migration will trigger TTM or userptr eviction, to evict user queues unexpectedly. Change helper amdgpu_ttm_tt_affect_userptr to return userptr which is inside the range. Add helper svm_range_check_vm_userptr to scan all userptr of the vm, and return overlap userptr bo start, last.

2021-10-13drm/amdkfd: handle svm partial migration cpages 0Philip Yang1-34/+52
migrate_vma_setup may return cpages 0, means 0 page can be migrated, treat this as error case to skip the rest of vma migration steps. Change svm_migrate_vma_to_vram and svm_migrate_vma_to_ram to return the number of pages migrated successfully or error code. The caller add up all the successful migration pages and update prange->actual_loc only if the total migrated pages is not 0. This also removes the warning message "VRAM BO missing during validation" if migration cpages is 0.
