Also in the common use case, those servers don't have a display connected. So add a Virtual connector, to reflect that even if no display is connected, the framebuffer can still be seen remotely.

Fix this by providing the proper detect callback for astdp and dp501. This also fixes the following regression: Since commit fae7d186403e ("drm/probe-helper: Default to 640x480 if no EDID on DP") The default resolution is now 640x480 when no monitor is connected. But Aspeed graphics is mostly used in servers, where no monitor is attached. This also affects the remote BMC resolution to 640x480, which is inconvenient, and breaks the anaconda installer. v2: Add .detect callback to the dp/dp501 connector (Jani Nikula) v3: Use .detect_ctx callback, and refactors (Thomas Zimmermann) Add a BMC virtual connector v4: Better indent detect_ctx() functions (Thomas Zimmermann) Fixes: fae7d186403e ("drm/probe-helper: Default to 640x480 if no EDID on DP") Signed-off-by: Jocelyn Falempe Reviewed-by: Thomas Zimmermann --- drivers/gpu/drm/ast/ast_dp.c | 11 ++++++++++ drivers/gpu/drm/ast/ast_dp501.c | 37 ++++++++++++++++++++++----------- drivers/gpu/drm/ast/ast_drv.h | 2 ++ drivers/gpu/drm/ast/ast_mode.c | 25 ++++++++++++++++++++++ 4 files changed, 63 insertions(+), 12 deletions(-) diff --git a/drivers/gpu/drm/ast/ast_dp.c b/drivers/gpu/drm/ast/ast_dp.c index 6dc1a09504e1..bf78f3d4aa3f 100644 --- a/drivers/gpu/drm/ast/ast_dp.c +++ b/drivers/gpu/drm/ast/ast_dp.c @@ -7,6 +7,17 @@ #include #include "ast_drv.h" +bool ast_astdp_is_connected(struct ast_device *ast) +{ + if (!ast_get_index_reg_mask(ast, AST_IO_CRTC_PORT, 0xD1, ASTDP_MCU_FW_EXECUTING)) + return false;
