Due to\nthis we need to ignore device ID when applying quirk for Dell XPS 14\nDA14260. Do this by adding DEVICE_ID_ANY and assign it to Dell XPS 14\nDA14260 quirk. Also apply the quirk only for eDP Panel Replay.\n\nFixes: 45c77d4bf8d4 (\"drm/i915/psr: Disable Panel Replay on Dell XPS 14 DA14260 as a quirk\")\nCc: Mika Kahola \nSigned-off-by: Jouni Högander \nReviewed-by: Mika Kahola \nLink: https://patch.msgid.link/20260320080403.1396926-1-jouni.hogander@intel.com\n(cherry picked from commit 1de647abdfda9dc307503d0a85152161850ba52c linux-next)\nSigned-off-by: Chia-Lin Kao (AceLan) \n---\n drivers/gpu/drm/i915/display/intel_psr.c | 3 ++-\n drivers/gpu/drm/i915/display/intel_quirks.c | 16 ++++++++++------\n drivers/gpu/drm/i915/display/intel_quirks.h | 2 +-\n 3 files changed, 13 insertions(+), 8 deletions(-)","diff":"diff --git a/drivers/gpu/drm/i915/display/intel_psr.c b/drivers/gpu/drm/i915/display/intel_psr.c\nindex f254b0af02588..afaf453f9051b 100644\n--- a/drivers/gpu/drm/i915/display/intel_psr.c\n+++ b/drivers/gpu/drm/i915/display/intel_psr.c\n@@ -647,7 +647,8 @@ static void _panel_replay_init_dpcd(struct intel_dp *intel_dp)\n \tif (intel_dp->mst_detect == DRM_DP_MST)\n \t\treturn;\n \n-\tif (intel_has_dpcd_quirk(intel_dp, QUIRK_DISABLE_PANEL_REPLAY)) {\n+\tif (intel_dp_is_edp(intel_dp) &&\n+\t intel_has_dpcd_quirk(intel_dp, QUIRK_DISABLE_EDP_PANEL_REPLAY)) {\n \t\tdrm_dbg_kms(display->drm,\n \t\t\t \"Panel Replay support not currently available for this setup\\n\");\n \t\treturn;\ndiff --git a/drivers/gpu/drm/i915/display/intel_quirks.c b/drivers/gpu/drm/i915/display/intel_quirks.c\nindex 722b559a84041..f5799997fac3a 100644\n--- a/drivers/gpu/drm/i915/display/intel_quirks.c\n+++ b/drivers/gpu/drm/i915/display/intel_quirks.c\n@@ -86,11 +86,11 @@ static void quirk_edp_limit_rate_hbr2(struct intel_display *display)\n \tdrm_info(display->drm, \"Applying eDP Limit rate to HBR2 quirk\\n\");\n }\n \n-static void quirk_disable_panel_replay(struct intel_dp *intel_dp)\n+static void quirk_disable_edp_panel_replay(struct intel_dp *intel_dp)\n {\n \tstruct intel_display *display = to_intel_display(intel_dp);\n \n-\tintel_set_dpcd_quirk(intel_dp, QUIRK_DISABLE_PANEL_REPLAY);\n+\tintel_set_dpcd_quirk(intel_dp, QUIRK_DISABLE_EDP_PANEL_REPLAY);\n \tdrm_info(display->drm, \"Applying disable Panel Replay quirk\\n\");\n }\n \n@@ -116,6 +116,8 @@ struct intel_dpcd_quirk {\n \n #define SINK_DEVICE_ID_ANY\tSINK_DEVICE_ID(0, 0, 0, 0, 0, 0)\n \n+#define DEVICE_ID_ANY\t\t0\n+\n /* For systems that don't have a meaningful PCI subdevice/subvendor ID */\n struct intel_dmi_quirk {\n \tvoid (*hook)(struct intel_display *display);\n@@ -261,11 +263,11 @@ static const struct intel_dpcd_quirk intel_dpcd_quirks[] = {\n \t},\n \t/* Dell XPS 14 DA14260 */\n \t{\n-\t\t.device = 0xb080,\n+\t\t.device = DEVICE_ID_ANY,\n \t\t.subsystem_vendor = 0x1028,\n \t\t.subsystem_device = 0x0db9,\n \t\t.sink_oui = SINK_OUI(0x00, 0x22, 0xb9),\n-\t\t.hook = quirk_disable_panel_replay,\n+\t\t.hook = quirk_disable_edp_panel_replay,\n \t},\n };\n \n@@ -277,7 +279,8 @@ void intel_init_quirks(struct intel_display *display)\n \tfor (i = 0; i < ARRAY_SIZE(intel_quirks); i++) {\n \t\tstruct intel_quirk *q = &intel_quirks[i];\n \n-\t\tif (d->device == q->device &&\n+\t\tif ((d->device == q->device ||\n+\t\t q->device == DEVICE_ID_ANY) &&\n \t\t (d->subsystem_vendor == q->subsystem_vendor ||\n \t\t q->subsystem_vendor == PCI_ANY_ID) &&\n \t\t (d->subsystem_device == q->subsystem_device ||\n@@ -300,7 +303,8 @@ void intel_init_dpcd_quirks(struct intel_dp *intel_dp,\n \tfor (i = 0; i < ARRAY_SIZE(intel_dpcd_quirks); i++) {\n \t\tconst struct intel_dpcd_quirk *q = &intel_dpcd_quirks[i];\n \n-\t\tif (d->device == q->device &&\n+\t\tif ((d->device == q->device ||\n+\t\t q->device == DEVICE_ID_ANY) &&\n \t\t (d->subsystem_vendor == q->subsystem_vendor ||\n \t\t q->subsystem_vendor == PCI_ANY_ID) &&\n \t\t (d->subsystem_device == q->subsystem_device ||\ndiff --git a/drivers/gpu/drm/i915/display/intel_quirks.h b/drivers/gpu/drm/i915/display/intel_quirks.h\nindex 77e490caed0d8..83214eb94b0c4 100644\n--- a/drivers/gpu/drm/i915/display/intel_quirks.h\n+++ b/drivers/gpu/drm/i915/display/intel_quirks.h\n@@ -21,7 +21,7 @@ enum intel_quirk_id {\n \tQUIRK_NO_PPS_BACKLIGHT_POWER_HOOK,\n \tQUIRK_FW_SYNC_LEN,\n \tQUIRK_EDP_LIMIT_RATE_HBR2,\n-\tQUIRK_DISABLE_PANEL_REPLAY,\n+\tQUIRK_DISABLE_EDP_PANEL_REPLAY,\n };\n \n void intel_init_quirks(struct intel_display *display);\n","prefixes":["SRU","Q","2/2"]}
