From 3c537889e17232e9073f75ae8710ea0f008c5a29 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Fri, 5 Feb 2010 04:21:19 -0500 Subject: drm/radeon/kms: add support for hardcoded edids in rom (v2) Some servers hardcode an edid in rom so that they will work properly with KVMs. This is a port of the relevant code from the ddx. [airlied: reworked to validate edid at boot stage - and remove special quirk, if there is a valid EDID in the BIOS rom we'll just try and use it.] Signed-off-by: Alex Deucher Signed-off-by: Dave Airlie --- include/drm/drm_edid.h | 3 +++ 1 file changed, 3 insertions(+) (limited to 'include/drm/drm_edid.h') diff --git a/include/drm/drm_edid.h b/include/drm/drm_edid.h index d33c3e03860..b4209898f11 100644 --- a/include/drm/drm_edid.h +++ b/include/drm/drm_edid.h @@ -201,4 +201,7 @@ struct edid { #define EDID_PRODUCT_ID(e) ((e)->prod_code[0] | ((e)->prod_code[1] << 8)) +/* define the number of Extension EDID block */ +#define DRM_MAX_EDID_EXT_NUM 4 + #endif /* __DRM_EDID_H__ */ -- cgit v1.2.3
