Add dmc firmware loading state and version to error state. v2: - Rebased on top of Damien's patches - included fw load state v3: include dmc info only if platform supports it (Chris) v4: move *csr to branch scope (Chris) v5: remove dependency to csr_state Cc: Chris Wilson Reviewed-by: Chris Wilson (v4) Signed-off-by: Mika Kuoppala Link: http://patchwork.freedesktop.org/patch/msgid/1446124879-22240-1-git-send-email-mika.kuoppala@intel.com Tested-by: Daniel Stone # SKL Signed-off-by: Ville Syrjälä --- diff --git a/drivers/gpu/drm/i915/i915_gpu_error.c b/drivers/gpu/drm/i915/i915_gpu_error.c index 793f2de2f910..27b6ac96b0ae 100644 --- a/drivers/gpu/drm/i915/i915_gpu_error.c +++ b/drivers/gpu/drm/i915/i915_gpu_error.c @@ -366,6 +366,17 @@ int i915_error_state_to_str(struct drm_i915_error_state_buf *m, err_printf(m, "Suspend count: %u\n", error->suspend_count); err_printf(m, "PCI ID: 0x%04x\n", dev->pdev->device); err_printf(m, "IOMMU enabled?: %d\n", error->iommu); + + if (HAS_CSR(dev)) { + struct intel_csr *csr = &dev_priv->csr; + + err_printf(m, "DMC loaded: %s\n", + yesno(csr->dmc_payload != NULL)); + err_printf(m, "DMC fw version: %d.%d\n", + CSR_VERSION_MAJOR(csr->version), + CSR_VERSION_MINOR(csr->version)); + } + err_printf(m, "EIR: 0x%08x\n", error->eir); err_printf(m, "IER: 0x%08x\n", error->ier); if (INTEL_INFO(dev)->gen >= 8) {
