>Description:
After hibernate and resume, X11 stops working. Keyboard and
mouse don't work, but Ctrl-Alt-F1 or Ctrl-Alt-Backspace works.
errors in dmesg:
****
drm:pid97650:__uc_init_hw *ERROR* [drm] *ERROR* GT0: GuC initialization
failed 0xfffffffffffffffae
drm:pid97650:intel_gt_init_hw *ERROR* [drm] *ERROR* GT0: Enabling uc
failed (-5)
drm:pid97650:intel_gt_resume *ERROR* [drm] *ERROR* GT0: Failed to
initialize GPU, declaring it wedged!
****
This happens because guc_wait_ucode() in i915/gt/uc/intel_guc_fw.c
fails.
The function is to wait for the GuC to start up by calling the inline
function guc_load_done() and the function checks two regisiters.
97 static inline bool guc_load_done(struct intel_uncore *uncore,
u32 *status, bool *success)
98 {
99 u32 val = intel_uncore_read(uncore, GUC_STATUS);
100 u32 uk_val = REG_FIELD_GET(GS_UKERNEL_MASK, val);
101 u32 br_val = REG_FIELD_GET(GS_BOOTROM_MASK, val);
102
103 *status = val;
104 switch (uk_val) {
105 case INTEL_GUC_LOAD_STATUS_READY:
106 *success = true;
107 return true;
108
109 case INTEL_GUC_LOAD_STATUS_ERROR_DEVID_BUILD_MISMATCH:
110 case INTEL_GUC_LOAD_STATUS_GUC_PREPROD_BUILD_MISMATCH:
111 case INTEL_GUC_LOAD_STATUS_ERROR_DEVID_INVALID_GUCTYPE:
In my test, the functions fails with the resgisters:
ukernel = INTEL_GUC_LOAD_STATUS_INIT_DATA_INVALID(0x71)
bootrom = INTEL_BOOTROM_STATUS_JUMP_PASSED(0x76)
When I was using 7.6, I didn't see this problem.
>How-To-Repeat:
1. hibernate or suspend
2. resume
the problem happens always (~10 times)
After the workaround diff, not happen always (~3 times)
>Fix:
Also the diff attached at last, workaround the problem.
The diff partially backouts the change on Feb 7 and add a printf().
I don't understand it logically, but if the printf() is removed, the
problem start happening.
