2024-10-07drm/xe/pf: Add functions to save and restore VF configuration blobMichal Wajdeczko
We already have support to save and restore GuC VF state, but that will only work when the target VF configuration (provisioning) will be exactly the same as the source VF configuration. To help with assuring that both configurations match, allow to encode whole VF configuration that can be saved as blob and restored later. In the future we may want to use such captured configuration blobs as templates to make sure we provision VFs with exactly the same configuration that was previously tested or recommended, or when debugfs knobs are not be available.

2024-10-07drm/xe/pf: Allow to encode subset of VF configuration KLVsMichal Wajdeczko
We want to reuse format of the GuC KLVs while saving and restoring VF configuration by the PF driver, but some of those KLVs (like doorbell begin index or GGTT starting offset) are not strictly needed to correctly restore VF configuration. Modify functions to omit encoding of some of the KLVs with GuC only details.

2024-10-07drm/xe/pf: Update success code of pf_validate_vf_config()Michal Wajdeczko
This function may return negative error codes on invalid or incomplete VF configuration, but unlike other int functions, it was returning 1 instead of 0 on success, which might be little inconvinient if we would like to use it directly in other functions.

2024-10-06drm/xe: Add memirq report page address helpersMichal Wajdeczko
Both xe_memirq_{source,status}_ptr functions are now strictly for obtaining an address of the memory based interrupt report pages used by the HW engines. When initializing the GuC that does not require special per instance page preparation, we don't need to abuse these public functions and pass a NULL instead of valid hwe pointer. Also, without further fixes, this actually may lead to NPD crash once the hw_reports_to_instance_zero() will be true. Add internal helpers that will provide report page addresses based solely on the instance number, which will be always 0 for both GuCs.

2024-10-04drm/xe: Make wedged_mode debugfs writableMatt Roper
The intent of this debugfs entry is to allow modification of wedging behavior, either from IGT tests or during manual debug; it should be marked as writable to properly reflect this. In practice this hasn't caused a problem because we always access wedged_mode as root, which ignores file permissions, but it's still misleading to have the entry incorrectly marked as RO.

2024-10-03drm/xe: Use fault injection infrastructure to find issues at probe timeFrancois Dugast
The kernel fault injection infrastructure is used to test proper error handling during probe. The return code of the functions using ALLOW_ERROR_INJECTION() can be conditionnally modified at runtime by tuning some debugfs entries. This requires CONFIG_FUNCTION_ERROR_INJECTION (among others). One way to use fault injection at probe time by making each of those functions fail one at a time is: FAILTYPE=fail_function DEVICE="0000:00:08.0" # depends on the system ERRNO=-12 # -ENOMEM, can depend on the function echo N > /sys/kernel/debug/$FAILTYPE/task-filter echo 100 > /sys/kernel/debug/$FAILTYPE/probability echo 0 > /sys/kernel/debug/$FAILTYPE/interval echo -1 > /sys/kernel/debug/$FAILTYPE/times echo 0 > /sys/kernel/debug/$FAILTYPE/space echo 1 > /sys/kernel/debug/$FAILTYPE/verbose modprobe xe echo $DEVICE > /sys/bus/pci/drivers/xe/unbind grep -oP "^.* \[xe\]" /sys/kernel/debug/$FAILTYPE/injectable | \ cut -d ' ' -f 1 | while read -r FUNCTION ; do echo "Injecting fault in $FUNCTION" echo "" > /sys/kernel/debug/$FAILTYPE/inject echo $FUNCTION > /sys/kernel/debug/$FAILTYPE/inject printf %#x $ERRNO > /sys/kernel/debug/$FAILTYPE/$FUNCTION/retval echo $DEVICE > /sys/bus/pci/drivers/xe/bind done rmmod xe It will also be integrated into IGT for systematic execution by CI. v2: Wrappers are not needed in the cases covered by this patch, so remove them and use ALLOW_ERROR_INJECTION() directly. v3: Document the use of fault injection at probe time in xe_pci_probe and refer to it where ALLOW_ERROR_INJECTION() is used.

Ensure we serialize with completion side to prevent UAF with fence going out of scope on the stack, since we have no clue if it will fire after the timeout before we can erase from the xa. Also we have some dependent loads and stores for which we need the correct ordering, and we lack the needed barriers.

The values of the variables xres and yres are placed in strbuf. These variables are obtained from strbuf1. The strbuf1 array contains digit characters and a space if the array contains non-digit characters. Then, when executing sprintf(strbuf, "%ux%ux8", xres, yres); more than 16 bytes will be written to strbuf. It is suggested to increase the size of the strbuf array to 24.

no_llseek had been defined to NULL two years ago, in commit 868941b14441 ("fs: remove no_llseek") To quote that commit, At -rc1 we'll need do a mechanical removal of no_llseek - git grep -l -w no_llseek | grep -v porting.rst | while read i; do sed -i '/\<no_llseek\>/d' $i done would do it. Unfortunately, that hadn't been done. Linus, could you do that now, so that we could finally put that thing to rest? All instances are of the form .llseek = no_llseek, so it's obviously safe.
