By allocating the uncached buffers from the bottom and the cacheable buffers from the top, we can reduce the amount of wasted space and also optimize allocation of the mappable portion of the GTT to only those buffers that require CPU access through the GTT. For other drivers, allocating small bos from one end and large ones from the other helps improve the quality of fragmentation.

| | * drm/dp: let drivers specify the name of the I2C-over-AUX adapterJani Nikula2014-03-181-0/+4

The i915 driver currently uses DPDDC-A to DPDDC-D as names for the DP i2c adapters. These names show up in the i2c sysfs name attribute. We'd like to be able to maintain that when switching over to the new helpers. Due to i2c device and connector cleanup ordering issues we also recently made the drm device (instead of connector) the parent of the i2c adapters: commit 80f65de3c9b8101c1613fa82df500ba6a099a11c Author: Imre Deak <imre.deak@intel.com> Date: Tue Feb 11 17:12:49 2014 +0200 drm/i915: dp: fix order of dp aux i2c device cleanup With the name picked up from the adapter parent using dev_name(), it would be the same for all i2c adapters with the current I2C-over-AUX helpers.

We should be able to handle the standard plane operations against primary planes in a generic way via the modeset handler. Drivers that can program primary planes more efficiently, that want to use their own primary plane structure to track additional information, or that don't have the limitations assumed by the helpers are free to provide their own implementation of some or all of these handlers. v3: Tweak kerneldoc formatting slightly to avoid ugliness v2: - Move plane helpers to a new file (drm_plane_helper.c) - Tighten checks on update handler (check for scaling, CRTC coverage, subpixel positioning) - Pass proper panning parameters to modeset interface - Disallow disabling primary plane (and thus CRTC) if other planes are still active on the CRTC. - Use a minimal format list that should work on all hardware/drivers. Drivers may call this function with a more accurate plane list to enable additional formats they can support.

This means we execute a lot of instructions (drm_get_connector_name(), in turn, calls snprintf() for example) to happily discard them in the normal case, drm.debug=0. So, let's put the test on drm_debug earlier, in the macros themselves. Sprinkle an unlikely() as well for good measure.

This allows simple buffer eviction and mapping-control. However, DRM core currently waits for the first ->open() on any char-dev to mark the underlying inode as backing inode of the device. This delayed initialization causes ugly conditions all over the place: if (dev->dev_mapping) do_sth(); To avoid delayed initialization and to stop reusing the inode of the char-dev, we allocate an anonymous inode for each DRM device and reset filp->f_mapping to it on ->open().

This will help us later to remove the drm_global_mutex requirement for minor-lookup. Furthermore, this also makes sure that minor->dev is always valid and takes a reference-count to the device as long as the minor is used in an open-file. This way, "struct file*"->private_data->dev is guaranteed to be valid (which it has to, as we cannot reset it).

| * | drm: provide device-refcountDavid Herrmann2014-03-161-1/+4

That's just utterly stupid. We manage "drm_minor" objects on each drm-device and each minor can have an unlimited number of open handles. Each of these handles has the drm_minor (and thus the drm_device) as private-data in the file-handle. Therefore, we may not destroy "drm_device" until all these handles are closed. It is *not* possible to reset all these pointers atomically and restrict access to them, and this is *not* how this is done! Instead, we use ref-counts to make sure the object is valid and not freed. Note that we currently use "dev->open_count" for that, which is *exactly* the same as a reference-count, just open coded. So this patch doesn't change any semantics on DRM devices (well, this patch just introduces the ref-count, anyway. Follow-up patches will replace open_count by it). Also note that generic VFS revoke support could allow us to drop this ref-count again. We could then just synchronously disable any fops->xy() calls. However, this is not the case, yet, and no such patches are in sight (and I seriously question the idea of dropping the ref-cnt again). Signed-off-by: David Herrmann <dh.herrmann@gmail.com>
