When dumping captured engine register state, print each register name alongside its MMIO offset to make the snapshot output easier to cross-reference with register definitions and hardware debug documentation. This improves postmortem analysis without changing capture contents. v2:(Sashiko) - Ensure lower DWORD prints v3:(Sashiko) - Use the LOW_DW MMIO offset(capture in last_address) when combined 64bit register values in the dump instead of HI_SW offset - preserve existing coredump register-name format and append register address as trailing metadata as a debug info and avoids disrupting existing format Signed-off-by: Nareshkumar Gollakoti --- drivers/gpu/drm/xe/xe_guc_capture.c | 18 ++++++++++++++---- 1 file changed, 14 insertions(+), 4 deletions(-) diff --git a/drivers/gpu/drm/xe/xe_guc_capture.c b/drivers/gpu/drm/xe/xe_guc_capture.c index 5a4d085660a2..3e99aef53b46 100644 --- a/drivers/gpu/drm/xe/xe_guc_capture.c +++ b/drivers/gpu/drm/xe/xe_guc_capture.c @@ -1716,6 +1716,7 @@ snapshot_print_by_list_order(struct xe_hw_engine_snapshot *snapshot, struct drm_ struct xe_devcoredump_snapshot *devcore_snapshot = &devcoredump->snapshot; struct gcap_reg_list_info *reginfo = NULL; u32 i, last_value = 0; + u32 last_address = 0; bool low32_ready = false; if (!list || !list->list || list->num_regs == 0) @@ -1743,6 +1744,7 @@ snapshot_print_by_list_order(struct xe_hw_engine_snapshot *snapshot, struct drm_ switch (reg_desc->data_type) { case REG_64BIT_LOW_DW: last_value = value; + last_address = reg_desc->reg.addr; /* * A 64 bit register define requires 2 consecutive @@ -1774,7 +1776,11 @@ snapshot_print_by_list_order(struct xe_hw_engine_snapshot *snapshot, struct drm_ XE_WARN_ON(!low32_ready); low32_ready = false; - drm_printf(p, "\t%s: 0x%016llx\n", reg_desc->regname, value_qw); + drm_printf(p, "\t%s: 0x%016llx [addr=0x%x]\n", + reg_desc->regname, + value_qw, + last_address); + break; } @@ -1788,10 +1794,14 @@ snapshot_print_by_list_order(struct xe_hw_engine_snapshot *snapshot, struct drm_ XE_WARN_ON(low32_ready); if (FIELD_GET(GUC_REGSET_STEERING_NEEDED, reg_desc->flags)) - drm_printf(p, "\t%s[%u]: 0x%08x\n", reg_desc->regname, - reg_desc->dss_id, value); + drm_printf(p, "\t%s[%u]: 0x%08x [addr=0x%x]\n", + reg_desc->regname, + reg_desc->dss_id, value, reg_desc->reg.addr); + else - drm_printf(p, "\t%s: 0x%08x\n", reg_desc->regname, value); + drm_printf(p, "\t%s: 0x%08x [addr=0x%x]\n", + reg_desc->regname, value, reg_desc->reg.addr); + break; } -- 2.43.0
