In the node i915_wa_registers, we could print out more information with whitelist, GT workaround and engine workaround.
In addition, fix the warning by checkpatch.pl: WARNING: Prefer seq_puts to seq_printf Signed-off-by: Chuansheng Liu <[email protected]> --- drivers/gpu/drm/i915/i915_debugfs.c | 60 ++++++++++++++++++++++++++++- 1 file changed, 58 insertions(+), 2 deletions(-) diff --git a/drivers/gpu/drm/i915/i915_debugfs.c b/drivers/gpu/drm/i915/i915_debugfs.c index 8f2525e4ce0f..d4d9e0396d71 100644 --- a/drivers/gpu/drm/i915/i915_debugfs.c +++ b/drivers/gpu/drm/i915/i915_debugfs.c @@ -1836,7 +1836,7 @@ static int i915_wa_registers(struct seq_file *m, void *unused) if (!count) continue; - seq_printf(m, "%s: Workarounds applied: %u\n", + seq_printf(m, "%s: context workarounds applied: %u\n", engine->name, count); for (wa = wal->list; count--; wa++) @@ -1844,9 +1844,65 @@ static int i915_wa_registers(struct seq_file *m, void *unused) i915_mmio_reg_offset(wa->reg), wa->set, wa->clr); - seq_printf(m, "\n"); + seq_puts(m, "\n"); } + for_each_uabi_engine(engine, i915) { + const struct i915_wa_list *wal = &engine->whitelist; + const struct i915_wa *wa; + unsigned int count; + + count = wal->count; + if (!count) + continue; + + seq_printf(m, "%s: whitelist applied: %u\n", + engine->name, count); + + for (wa = wal->list; count--; wa++) + seq_printf(m, "0x%X: 0x%08X, mask: 0x%08X\n", + i915_mmio_reg_offset(wa->reg), + wa->set, wa->clr); + + seq_puts(m, "\n"); + } + + { + const struct i915_wa_list *wal = &i915->gt_wa_list; + const struct i915_wa *wa; + unsigned int count; + + count = wal->count; + if (count) { + seq_printf(m, "gt workarounds applied: %u\n", count); + + for (wa = wal->list; count--; wa++) + seq_printf(m, "0x%X: 0x%08X, mask: 0x%08X\n", + i915_mmio_reg_offset(wa->reg), + wa->set, wa->clr); + } + seq_puts(m, "\n"); + } + + for_each_uabi_engine(engine, i915) { + const struct i915_wa_list *wal = &engine->wa_list; + const struct i915_wa *wa; + unsigned int count; + + count = wal->count; + if (!count) + continue; + + seq_printf(m, "%s: workaround list applied: %u\n", + engine->name, count); + + for (wa = wal->list; count--; wa++) + seq_printf(m, "0x%X: 0x%08X, mask: 0x%08X\n", + i915_mmio_reg_offset(wa->reg), + wa->set, wa->clr); + + seq_puts(m, "\n"); + } return 0; } -- 2.25.0.rc2 _______________________________________________ Intel-gfx mailing list [email protected] https://lists.freedesktop.org/mailman/listinfo/intel-gfx
