2014-04-18drm: Split out drm_probe_helper.c from drm_crtc_helper.cDaniel Vetter
This is leftover stuff from my previous doc round which I kinda wanted to do but didn't yet due to rebase hell. The modeset helpers and the probing helpers a independent and e.g. i915 uses the probing stuff but has its own modeset infrastructure. It hence makes to split this up. While at it add a DOC: comment for the probing libraray. It would be rather neat to pull some of the DocBook documenting these two helpers into in-line DOC: comments. But unfortunately kerneldoc doesn't support markdown or something similar to make nice-looking documentation, so the current state is better.

2014-04-04drm: Add support for two-ended allocation, v3Lauri Kasanen
Clients like i915 need to segregate cache domains within the GTT which can lead to small amounts of fragmentation. 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.

2014-04-01drm: Add primary plane helpers (v3)Matt Roper
When we expose non-overlay planes to userspace, they will become accessible via standard userspace plane API's. 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.

In the logging code, we are currently checking is we need to output in drm_ut_debug_printk(). This is too late. The problem is that when we write something like: DRM_DEBUG_DRIVER("ELD on [CONNECTOR:%d:%s], [ENCODER:%d:%s]\n", connector->base.id, drm_get_connector_name(connector), connector->encoder->base.id, drm_get_encoder_name(connector->encoder)); We start by evaluating the arguments (so call drm_get_connector_name() and drm_get_connector_name()) before ending up in drm_ut_debug_printk() which will then does nothing. 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.

2014-03-18drm/dp: let drivers specify the name of the I2C-over-AUX adapterJani Nikula
Let the drivers specify the name of the I2C-over-AUX adapter to maintain backwards compatibility in the sysfs when converting to the new I2C-over-AUX helper infrastructure. 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.

2014-03-18Merge branch 'drm-docs' of ssh://people.freedesktop.org/~danvet/drm into ↵Dave Airlie
drm-next Here's my drm documentation update and driver api polish pull request. Alex reviewed the entire pile, I've applied a little bit of spelling polish in a few places since then and otherwise the Usual Suspects (David, Rob, ...) don't seem up to have another look at it (I've poked them on irc). So I think it's as good as it gets ;-) Note that I've dropped the final imx breaker patch since that's blocked on imx getting sane. Once that's landed I'll ping you to pick up that straggler. * 'drm-docs' of ssh://people.freedesktop.org/~danvet/drm: (34 commits) drm/imx: remove drm_mode_connector_detach_encoder harder drm: kerneldoc polish for drm_crtc.c drm: kerneldoc polish for drm_crtc_helper.c drm: drop error code for drm_helper_resume_force_mode drm/crtc-helper: remove LOCKING from kerneldoc drm: remove return value from drm_helper_mode_fill_fb_struct drm/doc: Fix misplaced </para> drm: remove drm_display_mode->private_size drm: polish function kerneldoc for drm_modes.[hc] drm/modes: drop maxPitch from drm_mode_validate_size drm/modes: drop return value from drm_display_mode_from_videomode drm/modes: remove drm_mode_height/width drm: extract drm_modes.h for drm_crtc.h functions drm: move drm_mode related functions into drm_modes.c drm/doc: Repleace LOCKING kerneldoc sections in drm_modes.c drm/doc: Integrate drm_modes.c kerneldoc drm/kms: rip out drm_mode_connector_detach_encoder drm/doc: Add function reference documentation for drm_mm.c drm/doc: Overview documentation for drm_mm.c drm/mm: Remove MM_UNUSED_TARGET ...
2014-03-17drm/gma500: Remove unused ioctlsPatrik Jakobsson
All of these ioctls are unused and most of them just duplicate what drm already provides. Signed-off-by: Patrik Jakobsson <patrik.r.jakobsson@gmail.com>

Fix minor conflicts with drm-anon: - allocation/free order - drm_device header cleanups
2014-03-16drm: remove redundant minor->device fieldDavid Herrmann
Whenever we access minor->device, we are in a minor->kdev->...->fops callback so the minor->kdev pointer *must* be valid. Thus, simply use minor->kdev->devt instead of minor->device and remove the redundant field. Signed-off-by: David Herrmann <dh.herrmann@gmail.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2014-03-16drm: add minor-lookup/release helpersDavid Herrmann
Instead of accessing drm_minors_idr directly, this adds a small helper to hide the internals. 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).

2014-03-16drm: provide device-refcountDavid Herrmann
Lets not trick ourselves into thinking "drm_device" objects are not ref-counted. 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>
2014-03-16drm: turn DRM_MINOR_* into enumDavid Herrmann
Use enum for DRM_MINOR_* constants to avoid hard-coding the IDs. Furthermore, add a DRM_MINOR_CNT so we can perform range-checks in follow-ups. This changes the IDs of the minor-types by -1, but they're not used as indices so this is fine.

2014-03-16drm: init TTM dev_mapping in ttm_bo_device_init()David Herrmann
With dev->anon_inode we have a global address_space ready for operation right from the beginning. Therefore, there is no need to do a delayed setup with TTM. Instead, set dev_mapping during initialization in ttm_bo_device_init() and remove any "if (dev_mapping)" conditions.
