However, many laptops will send more then just an ATIF event and -will also send an ACPI_VIDEO_NOTIFY_PROBE event as well. Since we don't -check for this, we return NOTIFY_DONE which causes a keypress for the -ACPI event to be propogated to userspace. This is the equivalent of -someone pressing the display key on a laptop every time there's a -hotplug event. - -So, check for ACPI_VIDEO_NOTIFY_PROBE events and suppress keypresses -from them. - -Signed-off-by: Lyude Paul <lyude@redhat.com> -Cc: stable@vger.kernel.org -Signed-off-by: Alex Deucher <alexander.deucher@amd.com> ---- - drivers/gpu/drm/amd/amdgpu/amdgpu_acpi.c | 17 ++++++++++++----- - 1 file changed, 12 insertions(+), 5 deletions(-) - -diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_acpi.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_acpi.c -index 6488e90..7f0afc5 100644 ---- a/drivers/gpu/drm/amd/amdgpu/amdgpu_acpi.c -+++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_acpi.c -@@ -359,7 +359,9 @@ static int amdgpu_atif_get_sbios_requests(struct amdgpu_atif *atif, - * - * Checks the acpi event and if it matches an atif event, - * handles it. -- * Returns NOTIFY code -+ * -+ * Returns: -+ * NOTIFY_BAD or NOTIFY_DONE, depending on the event. - */ - static int amdgpu_atif_handler(struct amdgpu_device *adev, - struct acpi_bus_event *event) -@@ -373,11 +375,16 @@ static int amdgpu_atif_handler(struct amdgpu_device *adev, - if (strcmp(event->device_class, ACPI_VIDEO_CLASS) != 0) - return NOTIFY_DONE; - -+ /* Is this actually our event? */ - if (!atif || - !atif->notification_cfg.enabled || -- event->type != atif->notification_cfg.command_code) -- /* Not our event */ -- return NOTIFY_DONE; -+ event->type != atif->notification_cfg.command_code) { -+ /* These events will generate keypresses otherwise */ -+ if (event->type == ACPI_VIDEO_NOTIFY_PROBE) -+ return NOTIFY_BAD; -+ else -+ return NOTIFY_DONE; -+ } - - if (atif->functions.sbios_requests) { - struct atif_sbios_requests req; -@@ -386,7 +393,7 @@ static int amdgpu_atif_handler(struct amdgpu_device *adev, - count = amdgpu_atif_get_sbios_requests(atif, &req); - - if (count <= 0) -- return NOTIFY_DONE; -+ return NOTIFY_BAD; - - DRM_DEBUG_DRIVER("ATIF: %d pending SBIOS requests\n", count); - --- -2.7.4 - |
