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 ...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

Thus far we've only grabbed the overall modeset lock, but that already failed to exclude a pile of potential concurrent operations. With proper atomic support this will be worse. So add a trylock mode to the modeset locking code which attempts all locks only with trylocks, if possible. We need to track this in the locking functions themselves and can't restrict this to drivers since driver-private w/w mutexes must be treated the same way. There's still the issue that other driver private locks aren't handled here at all, but well can't have everything. With this we will at least not regress, even once atomic allows lots of concurrent kms activity. Aside: We should move the acquire context to stack-based allocation in the callers to get rid of that awful WARN_ON(kmalloc_failed) control flow which just blows up when memory is short. But that's material for separate patches. v2: - Fix logic inversion fumble in the fb helper. - Add proper kerneldoc.

Which doesn't cause havoc since we only do that while constructing the new state, so no driver or hardware state change has happened. The only troubling bit is the fb refcounting the core does - if someone else has snuck in then it might potentially unref an outdated framebuffer. To fix that move the old_fb temporary storage into struct drm_plane for all ioctls, so that the atomic helpers can update it. v2: Fix up the error case handling as suggested by Matt Roper and just grab locks uncoditionally - there's no point in optimizing the locking for when userspace gets it wrong.

Examples would be locks to protect shared state like shared display PLLs. Unfortunately the legacy ioctls assume that all locking is fully done by the drm core. Now for those paths which grab all locks we already have to keep around an acquire context in dev->mode_config. Helper functions that implement legacy interfaces in terms of atomic support can therefore grab this acquire contexts and reuse it. The only interfaces left are the cursor and pageflip ioctls. So add functions to grab the crtc lock these need using an acquire context and preserve it for atomic drivers to reuse. v2: - Fixup comments&kerneldoc. - Drop the WARNING from modeset_lock_all_crtcs since that can be used in legacy paths with crtc locking. v3: Fix a type on the kerneldoc Dave spotted.

We already have a drm_crtc_index function so add the missing ones for planes and connectors. If it later on turns out that the list walking is too expensive we can add the index to the relevant modeset objects. Rob Clark doesn't like the loops too much, but we can always add an obj->idx parameter later on. And for now reiterating is actually safer since nowadays we have hotpluggable connectors (thanks to DP MST). v2: Fix embarrassing copypasta fail in kerneldoc and header declarations, spotted by Matt Roper.

The user's wishes are determined by what, if any, mode is specified on the command line (via the video= parameter). However, that command line mode is first parsed by drm_fb_helper_initial_config() which is called after i915.ko's custom initial_config() as a fallback method. So in order for us to honour it, we need to move the cmdline parser earlier. If we perform the connector cmdline parsing as soon as we initialise the connector, that cmdline mode and forced status is then available even if the fbdev helper is not compiled in or never called. We also then expose the cmdline user mode in the connector mode lists. v2: Rebase after connector->name upheaval. v3: Adapt mga200 to look for the cmdline mode in the new place. Nicely simplifies things while at that. v4: Fix checkpatch. v5: Select FB_CMDLINE to adapt to the changed fbdev patch.
