* drm: Create drm legacy driver headerDaniel Vetter2014-09-121-15/+0
| | | | | | | | | | | And move a few legayc functions to start things over there. It compiles ... Inspired by a patch from Dave Airlie, but with a split between drm.ko private legacy functions and stuff used by drivers. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

Also with backmerge like you've requested for easier merging. The neat thing this finally allows is to immediately disable the vblank interrupt on the last drm_vblank_put if the hardware has perfectly accurate vblank counter and timestamp readout support. On i915 that required piles of small adjustements from Ville since depending upon the platform and port the vblank happens at different scanout lines. Of course this is fully opt-in and per-device (we need that since gen2 doesn't have a hw vblank counter). * tag 'topic/vblank-rework-2014-09-12' of git://anongit.freedesktop.org/drm-intel: (22 commits) drm: Clarify vblank ts/scanoutpos sampling #defines drm: Simplify return value of drm_get_last_vbltimestamp drm: Only update final vblank count when precise ts is available drm: Really never disable vblank irqs for offdelay==0 drm: Use vblank_disable_and_save in drm_vblank_cleanup() drm: Remove drm_vblank_cleanup from drm_vblank_init error path. drm: Store the vblank timestamp when adjusting the counter during disable drm: Fix confusing debug message in drm_update_vblank_count() drm/i915: Update scanline_offset only for active crtcs drm: Kick start vblank interrupts at drm_vblank_on() drm/i915: Opt out of vblank disable timer on >gen2 drm: Add dev->vblank_disable_immediate flag drm: Disable vblank interrupt immediately when drm_vblank_offdelay<0 drm: Fix race between drm_vblank_off() and drm_queue_vblank_event() drm: Fix deadlock between event_lock and vbl_lock/vblank_time_lock drm: Reduce the amount of dev->vblank[crtc] in the code drm: Avoid random vblank counter jumps if the hardware counter has been reset drm: Have the vblank counter account for the time between vblank irq disable and drm_vblank_off() drm: Move drm_update_vblank_count() drm: Don't clear vblank timestamps when vblank interrupt is disabled ...

I'm not sure how useful the complicated bitmask return value of these functions really are since no one checks them. But for now let's keep things as is.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | One step closer to dropping all the drm_bus_* code: Add a driver->set_busid() callback and make all drivers use the generic helpers. Nouveau is the only driver that uses two different bus-types with the same drm_driver. This is totally broken if both buses are available on the same machine (unlikely, but lets be safe). Therefore, we create two different drivers for each platform during module_init() and set the set_busid() callback respectively.

The only reason to keep support in code is if developers wanted to disable debug support. Sounds unlikely. All the DRM_DEBUG() printks are still guarded by a drm_debug read. So if its cacheline is read once, they're discarded pretty fast.. There should hardly be any performance penalty, it's even guarded by unlikely().

Order them alphabetically, linux/ first, then asm/ and then local drm/ includes. Since a long time ago, kernel headers have been converted to include required headers themselves. No-one cares whether that means the compiler has to include a header multiple times. In fact, GCC already does some optimization regarding multiple inclusions if a sorrounding #ifndef is present.

Thanks to Chris: "drm_file->is_master is not synomous with having drm_file->master == drm_file->minor->master. This is because drm_file->master is the same for all drm_files of the same generation and so when there is a master, every drm_file believes itself to be the master. Confusion ensues and things go pear shaped when one file is closed and there is no master anymore." Conflicts: drivers/gpu/drm/drm_drv.c drivers/gpu/drm/drm_stub.c

| * | drm: make sysfs device always available for minorsDavid Herrmann2014-08-051-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For each minor we allocate a sysfs device as minor->kdev. Currently, this is allocated and registered in drm_minor_register(). This makes it impossible to add sysfs-attributes to the device before it is registered. Therefore, they are not added atomically, nor can we move device_add() *after* ->load() is called. This patch makes minor->kdev available early, but only adds the device during minor-registration. Note that the registration is still called before ->load() as debugfs needs to be split, too. This will be fixed in follow-ups.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most of the new DRM management functions are nowadays in drm_stub.c. By moving the core module initialization to drm_stub.c we can make several global variables static and keep the stub-open helper local. The core files now look like this: drm_stub.c: Core management drm_drv.c: Ioctl dispatcher drm_ioctl.c: Actual ioctl backends drm_fops.c: Char-dev file-operations A follow-up patch will move what is left from drm_drv.c into drm_ioctl.c.

| * | drm: don't de-authenticate clients on master-closeDavid Herrmann2014-08-051-1/+0

However, if an inactive DRM-Master closes its device, we do nothing. This is quite inconsistent and breaks several scenarios: 1) If this was used as security mechanism, it fails horribly if a master closes a device while VT switched away. Furthermore, none of the few drivers using ->master_*() callbacks seems to require it, anyway. 2) If you spawn weston (or any other non-UMS compositor) in background while another compositor is active, both will get assigned to the same "drm_master" object. If the foreground compositor now exits, all clients of both the foreground AND background compositor will be de-authenticated leading to unexpected behavior. Stop this non-sense and keep clients authenticated. We don't do this when dropping DRM-Master (i.e., switching VTs) so don't do it on active-close either!

Given that the default mapping_gfp_mask() is GFP_HIGHUSER, it is _very_ unlikely that anyone will ever make use of that parameter. In fact, all drivers currently pass redundant flags or 0. This patch removes the 'gfp' parameter. The only reason to keep it is to remove flags like __GFP_WAIT. But in its current form, it can only be used to add flags. So to remove __GFP_WAIT, you'd have to drop it from the mapping_gfp_mask, which again is stupid as this mask is used by shmem-core for other allocations, too. If any driver ever requires that parameter, we can introduce a new helper that takes the raw 'gfp' parameter. The caller'd be responsible to combine it with mapping_gfp_mask() in a suitable way. The current drm_gem_get_pages() helper would then simply use mapping_gfp_mask() and call the new helper. This is what shmem_read_mapping_pages{_gfp,} does right now. Moreover, the gfp-zone flag-usage is not obvious: If you pass a modified zone, shmem core will WARN() or even BUG(). In other words, the following must be true for 'gfp' passed to shmem_read_mapping_pages_gfp(): gfp_zone(mapping_gfp_mask(mapping)) == gfp_zone(gfp) Add a comment to drm_gem_read_pages() explaining that constraint.
