After commit f651c8b0 ("drm/virtio: factor out the sg_table from virtio_gpu_object"), virtio_gpu_create_object allocates too small space to fit everything in. It is because it allocates struct virtio_gpu_object, but should allocate a newly added struct virtio_gpu_object_shmem which has 2 more members. So fix that by using correct type in virtio_gpu_create_object. Signed-off-by:

drm_mode_config_init() may not have been called when the driver/device doesn't support modeset. That will cause drm_mode_config_validate() to oops. Skip the validation for !modeset.

As a result of commit 987d65d0 (drm: debugfs: make drm_debugfs_create_files() never fail) and changes to various debugfs functions in drm/core and across various drivers, there is no need for the drm_driver.debugfs_init() hook to have a return value. Therefore, declare it as void. This also includes refactoring all users of the .debugfs_init() hook to return void across the subsystem. v2: include changes to the hook and drivers that use it in one patch to prevent driver breakage and enable individual successful compilation of this change.

Many drivers are populating encoder->possible_clones wrong. Let's persuade them to get it right by adding some loud WARNs. We'll cross check the bits between any two encoders. So either both encoders can clone with the other, or neither can. We'll also complain about effectively empty possible_clones, and possible_clones containing bits for encoders that don't exist. v2: encoder->possible_clones now includes the encoder itelf v3: Move to drm_mode_config_validate() (Daniel) Document that you get a WARN when this is wrong (Daniel) Extract full_encoder_mask() v4: !! instead of !

It's not at all clear what cloning options this driver supports. So let's just clear possible_clones instead of setting it to some bogus value. v2: Adjust the FIXME (Daniel) Cc: Philipp Zabel <p.zabel@pengutronix.de> Acked-by:

Ville Syrjälä authored
I doubt the DP+DP and SDVO+SDVO cloning works for this driver. i915 at least doesn't do those. Truthfully there could be some very specific circumstances where some of them would do doable, but genereally it's too much pain to deal with so we've chose not to bother. Let's use the same approach for gma500. Also the LVDS+LVDS and DSI+DSI cases probably don't really exist as there is one of each at most. This does mean we'll now leave possible_clones at 0 for these encoder types whereas previosuly we included the encoder itself in the bitmask. But that's fine as the core now treaks 0 as a special case and adds the encoder itself into the final bitmask reported to userspace. Cc: Patrik Jakobsson <patrik.r.jakobsson@gmail.com> Acked-by:

Ville Syrjälä authored
The docs say possible_clones should always include the encoder itself. Since most drivers don't want to deal with the complexities of cloning let's allow them to set possible_clones=0 and instead we'll fix that up in the core. We can't put this special case into drm_encoder_init() because drivers will have to fill up possible_clones after adding all the relevant encoders. Otherwise they wouldn't know the proper encoder indexes to use. So we'll just do it just before registering the device. v2: Don't set the bit if possible_clones!=0 so that the validation (coming soon) will WARN (Thomas) Fix up the docs to allow possible_clones==0 (Daniel) .late_register() is too late, introduce drm_mode_config_validate() which gets called _before_ we register the char device (Daniel) Acked-by: -

Currently the DispID tile block gets parsed in drm_get_edid(), which is an odd place for it considering we parse nothing else there. Also this doesn't work for override EDIDs since drm_connector_update_edid_property() refuses to do its job twice in such cases. Thus we never update the tile property with results of the DispID tile block parsing during drm_get_edid(). To fix this let's just move the tile block parsing to happen during drm_connector_update_edid_property(), which is where we parse a bunch of other stuff as well (and where we update both the EDID and tile properties).

The EDID extension block checksum byte is not part of the actual DispID data, so don't use it in validate_displayid(). Signed-off-by:
-
Ville Syrjälä authored
Currently the code assumes that the entire EDID extesion block can be taken up by the DispID blocks. That is not true. There is at least always the DispID checksum, and potentially fill bytes if the extension block uses the interior fill scheme to pad out to fill EDID block size. So let's not parse the checksum or the fill bytes as DispID blocks by having drm_find_displayid_extension() return the actual length of the DispID data to the caller. Signed-off-by:

Instead of everyone having to call validate_displayid() let's just have drm_find_displayid_extension() do it for them. Signed-off-by:

Ville Syrjälä authored
As with the byte offset (idx) drm_find_displayid_extension() is the only one who actually knows how much data the resulting DispID block can contain. So return the length from therein instead of assuming it's the EDID block length all over. Signed-off-by:
-
Ville Syrjälä authored
The fact that the DispID starts at byte offset 1 is due to the DispID coming from and EDID extension block (the first byte being the extesion block tag). Instead of hadrdocoding that idx==1 assumptions all over let's just have drm_find_displayid_extension() return it since it actually knows what it's talking about. If at some point someone comes across a DispID which is not embedded inside an EDID the function that returns the new type of DispID can return it's own byte offset without having to updated all the code. TODO: should probably just get rid of that idx thing altogether and just return the thing we want directly. Signed-off-by: -
