2024-04-22drm/buddy: Implement tracking clear page featureArunpravin Paneer Selvam
- Add tracking clear page feature. - Driver should enable the DRM_BUDDY_CLEARED flag if it successfully clears the blocks in the free path. On the otherhand, DRM buddy marks each block as cleared. - Track the available cleared pages size - If driver requests cleared memory we prefer cleared memory but fallback to uncleared if we can't find the cleared blocks. when driver requests uncleared memory we try to use uncleared but fallback to cleared memory if necessary. - When a block gets freed we clear it and mark the freed block as cleared, when there are buddies which are cleared as well we can merge them. Otherwise, we prefer to keep the blocks as separated. - Add a function to support defragmentation. v1: - Depends on the flag check DRM_BUDDY_CLEARED, enable the block as cleared. Else, reset the clear flag for each block in the list(Christian) - For merging the 2 cleared blocks compare as below, drm_buddy_is_clear(block) != drm_buddy_is_clear(buddy)(Christian) - Defragment the memory beginning from min_order till the required memory space is available. v2: (Matthew) - Add a wrapper drm_buddy_free_list_internal for the freeing of blocks operation within drm buddy. - Write a macro block_incompatible() to allocate the required blocks. - Update the xe driver for the drm_buddy_free_list change in arguments. - add a warning if the two blocks are incompatible on defragmentation - call full defragmentation in the fini() function - place a condition to test if min_order is equal to 0 - replace the list with safe_reverse() variant as we might remove the block from the list. v3: - fix Gitlab user reported lockup issue. - Keep DRM_BUDDY_HEADER_CLEAR define sorted(Matthew) - modify to pass the root order instead max_order in fini() function(Matthew) - change bool 1 to true(Matthew) - add check if min_block_size is power of 2(Matthew) - modify the min_block_size datatype to u64(Matthew) v4: - rename the function drm_buddy_defrag with __force_merge. - Include __force_merge directly in drm buddy file and remove the defrag use in amdgpu driver. - Remove list_empty() check(Matthew) - Remove unnecessary space, headers and placement of new variables(Matthew) - Add a unit test case(Matthew) v5: - remove force merge support to actual range allocation and not to bail out when contains && split(Matthew) - add range support to force merge function. v6: - modify the alloc_range() function clear page non merged blocks allocation(Matthew) - correct the list_insert function name(Matthew).

2024-04-22ACPI: CPPC: Fix access width used for PCC registersVanshidhar Konda
commit 2f4a4d63a193 ("ACPI: CPPC: Use access_width over bit_width for system memory accesses") modified cpc_read()/cpc_write() to use access_width to read CPC registers. However, for PCC registers the access width field in the ACPI register macro specifies the PCC subspace ID. For non-zero PCC subspace ID it is incorrectly treated as access width. This causes errors when reading from PCC registers in the CPPC driver. For PCC registers, base the size of read/write on the bit width field. The debug message in cpc_read()/cpc_write() is updated to print relevant information for the address space type used to read the register.

2024-04-22cxl/core: Fix potential payload size confusion in cxl_mem_get_poison()Dan Williams
A recent change to cxl_mem_get_records_log() [1] highlighted a subtle nuance of looping calls to cxl_internal_send_cmd(), i.e. that cxl_internal_send_cmd() modifies the 'size_out' member of the @mbox_cmd argument. That mechanism is useful for communicating underflow, but it is unwanted when reusing @mbox_cmd for a subsequent submission. It turns out that cxl_xfer_log() avoids this scenario by always redefining @mbox_cmd each iteration. Update cxl_mem_get_records_log() and cxl_mem_get_poison() to follow the same style as cxl_xfer_log(), i.e. re-define @mbox_cmd each iteration. The cxl_mem_get_records_log() change is just a style fixup, but the cxl_mem_get_poison() change is a potential fix, per Alison [2]: Poison list retrieval can hit this case if the MORE flag is set and a follow on read of the list delivers more records than the previous read. ie. device gives one record, sets the _MORE flag, then gives 5. Not an urgent fix since this behavior has not been seen in the wild, but worth tracking as a fix.

Detect and mitigate inode collsions that now occur since we fixed 9p generating duplicate inode structures. Underlying cause of these appears to be a race condition between reuse of inode numbers in underlying file system and cleanup of inode numbers in the client.

2024-04-22drm/i915/dmc: change how to disable DMC firmware using module paramJani Nikula
The distinction between the dmc_firmware_path module param being NULL and the empty string "" is problematic. It's not possible to set the parameter back to NULL via sysfs or debugfs. Remove the distinction, and consider NULL and the empty string to be the same thing, and use the platform default for them. This removes the possibility to disable DMC (and runtime PM) via i915.dmc_firmware_path="".

2024-04-22bnxt_en: Fix the PCI-AER routinesVikas Gupta
We do not support two simultaneous recoveries so check for reset flag, BNXT_STATE_IN_FW_RESET, and do not proceed with AER further. When the pci channel state is pci_channel_io_frozen, the PCIe link can not be trusted so we disable the traffic immediately and stop BAR access by calling bnxt_fw_fatal_close(). BAR access after AER fatal error can cause an NMI. Fixes: f75d9a0aa967 ("bnxt_en: Re-write PCI BARs after PCI fatal error.")

2024-04-22drm/xe: Kill xe_device_mem_access_{get*,put}Rodrigo Vivi
Let's simply convert all the current callers towards direct xe_pm_runtime access and remove this extra layer of indirection. No functional change is expected with this patch since xe_mem_access_get was already using the xe_pm_runtime_get_noresume at this point. v2: Convert all the current callers instead of a big refactor at once. v3: - Rebased - Squashed the GSC/HDCP - Added a new case: sriov_pf_policy - Improved commit message to highlight that there's no functional change in this patch.

2024-04-22sched/eevdf: Prevent vlag from going out of bounds in reweight_eevdf()Xuewen Yan
It was possible to have pick_eevdf() return NULL, which then causes a NULL-deref. This turned out to be due to entity_eligible() returning falsely negative because of a s64 multiplcation overflow. Specifically, reweight_eevdf() computes the vlag without considering the limit placed upon vlag as update_entity_lag() does, and then the scaling multiplication (remember that weight is 20bit fixed point) can overflow. This then leads to the new vruntime being weird which then causes the above entity_eligible() to go side-ways and claim nothing is eligible. Thus limit the range of vlag accordingly. All this was quite rare, but fatal when it does happen.

2024-04-22drm/edid: Parse topology block for all DispID structure v1.xVille Syrjälä
DisplayID spec v1.3 revision history notes do claim that the toplogy block was added in v1.3 so requiring structure v1.2 would seem correct, but there is at least one EDID in edid.tv with a topology block and structure v1.0. And there are also EDIDs with DisplayID structure v1.3 which seems to be totally incorrect as DisplayID spec v1.3 lists structure v1.2 as the only legal value. Unfortunately I couldn't find copies of DisplayID spec v1.0-v1.2 anywhere (even on vesa.org), so I'll have to go on empirical evidence alone. We used to parse the topology block on all v1.x structures until the check for structure v2.0 was added. Let's go back to doing that as the evidence does suggest that there are DisplayIDs in the wild that would miss out on the topology stuff otherwise. Also toss out DISPLAY_ID_STRUCTURE_VER_12 entirely as it doesn't appear we can really use it for anything. I *think* we could technically skip all the structure version checks as the block tags shouldn't conflict between v2.0 and v1.x. But no harm in having a bit of extra sanity checks I guess. So far I'm not aware of any user reported regressions from overly strict check, but I do know that it broke igt/kms_tiled_display's fake DisplayID as that one gets generated with structure v1.0.
