* drm/nouveau/core: rebase object ref/use counts after ctor/init/fini eventsBen Skeggs2013-04-26
| | | | | | | | | | | This is intended to support named (with a handle, etc) objects having children that don't have an outside reference. This will replace the various hacks around the place where subdev objects have children, and have to manually drop the self-refs so that they can be destroyed etc when all the outside refs have gone.

* drm/nouveau/mc: handle irq-related setup ourselvesBen Skeggs2013-04-26
| | | | | | | | We need to be able to process interrupts before the DRM code is able to actually enable them, set it up ourselves. Also, it's less convoluted to *not* use the DRM wrappers it appears... Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
* drm/nv04/disp: hide all the cruft away in its own little holeBen Skeggs2013-04-26
| | | | | | | | | | | | | | | It'd be pretty awesome if someone would care enough to port this all properly to a class interface, perhaps submitting a command stream to the core via a sw object on PFIFO (emulating how EVO works basically, and also what nvidia have done forever..).. But, this seems unlikely given how old this hardware is now, so, lets just hide it away. There's a heap of other bits and pieces laying around that are still tangled. I'll (re)move them in pieces.

* drm/nve0: magic up some support for GF117Ben Skeggs2013-04-26
| | | | | | | | | | | Seen in the wild, don't have the hardware but this hacks things up to treat it the same as GF119 for now. Should be relatively safe, I'd be very surprised if anything major changed outside of PGRAPH. PGRAPH (3D etc) is disabled by default however until it's confirmed working.

| | | | | | | | Compression not supported, and will be silently dropped. Original G80 can't handle this either and requires LINEAR memtype, though it's still possible to correctly texture and m2mf to/from these objects anyway. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

* drm/shmobile: Fix race condition between page flip request and handlerLaurent Pinchart2013-04-25
| | | | | | | | | | | | | | | | | The page flip handler stores the page flip event pointer and then calls drm_vblank_get() to enable the vblank interrupt. Due to the vblank off delay, the vblank interrupt can be enabled in the hardware at that point, even if the vblank reference count is equal to 0. If a vblank interrupt is triggered between storing the event pointer and calling drm_vblank_get(), the page flip completion handler will process the event and call drm_vblank_put() with a reference count equal to 0. This will result in a BUG_ON. Fix the race condition by calling drm_vblank_get() before storing the event pointer.

* drm: export drm_vm_open_lockedArnd Bergmann2013-04-25
| | | | | | | | | | | | | | | The EXYNOS DRM driver uses drm_vm_open_locked in its mmap() function, and it can be built as a loadable module, which currently fails. This exports the symbol from the DRM core to avoid ERROR: "drm_vm_open_locked" [drivers/gpu/drm/exynos/exynosdrm.ko] undefined!

* drm/tilcdc: use only a single module device tableArnd Bergmann2013-04-25
| | | | | | | | | | | | | | | | | | | | | | The tilcdc driver fails to be built as a module because of extraneous MODULE_DEVICE_TABLE entries: drivers/gpu/drm/tilcdc/tilcdc_slave.o:(.data+0x54): multiple definition of `__mod_of_device_table' drivers/gpu/drm/tilcdc/tilcdc_tfp410.o:(.data+0x54): first defined here drivers/gpu/drm/tilcdc/tilcdc_panel.o:(.data+0x54): multiple definition of `__mod_of_device_table' drivers/gpu/drm/tilcdc/tilcdc_tfp410.o:(.data+0x54): first defined here drivers/gpu/drm/tilcdc/tilcdc_drv.o:(.data+0x184): multiple definition of `__mod_of_device_table' drivers/gpu/drm/tilcdc/tilcdc_tfp410.o:(.data+0x54): first defined here Since the entire point of these entries is to make the module autoload when one of the devices is present, it's enough to keep the one entry for "ti,am33xx-tilcdc", which should always be there if any of the others are.

* Merge branch 'gma500-fixes' of git://github.com/patjak/drm-gma500 into drm-nextDave Airlie2013-04-25
|\ | | | | | | | | | | | | | | | | | | Two fixes for gma500. First one from Anisse allows us to handle ASLE irqs even when BIOS doesn't trigger a pipe event irq. The second one allows dual head setups to have a big shared framebuffer. * 'gma500-fixes' of git://github.com/patjak/drm-gma500: drm/gma500: Increase max resolution for mode setting drm/gma500: fix backlight hotkeys behaviour on netbooks
| * drm/gma500: Increase max resolution for mode settingPatrik Jakobsson2013-04-25
| | | | | | | | | | | | | | | | By having a higher max resolution we can now set up a virtual framebuffer that spans several monitors. 4096 should be ok since we're gen 3 or higher and should be enough for most dual head setups. Signed-off-by: Patrik Jakobsson <patrik.r.jakobsson@gmail.com>
| * drm/gma500: fix backlight hotkeys behaviour on netbooksAnisse Astier2013-04-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Backlight hotkeys weren't working before on certain cedartrail laptops. The source of this problem is that the hotkeys' ASLE opregion interrupts were simply ignored. Driver seemed to expect the interrupt to be associated with a pipe, but it wasn't. Accepting the ASLE interrupt without an associated pipe event flag fixes the issue, the backlight code is called when needed, making the brightness keys work properly.
