At the moment, we only read it at startup time, so we can just unmap it there
when we're done.

Add code to get panel modes from the VBIOS if present and check whether certain
outputs exist. Should make our display detection code a little more robust.
|
|
Makes printing modelines from some routines easier.
|
|
The dummy read page will point to NULL if drm_bo_driver_init failed at
firstopen (modeset is not enabled), and will cause kernel oops at
subsequent drm_lastclose call, so be sure to check it.

This reverts commit bc0836e12a9790f1cc83f8bc29bc05043c4bc840.
tree has some kref hacks in it - oops

Thanks to Alex for supplying this info.

It would be nice if one day the DRM driver was the canonical source for
register definitions and core macros. To that end, this patch cleans
things up quite a bit, removing redundant definitions (some with
different names referring to the same register) and generally tidying up
the header file.

In order to avoid recursive ->detect->interrupt->detect->interrupt->...
we need to disable TV hotplug interrupts in
intel_tv.c:intel_tv_detect_type. We also need to enable the TV interrupt
detection and hotplug sequence properly in i915_irq.c.

drm_crtc->fb may point to NULL, f.e X server will allocate a new fb
and assign it to the CRTC at startup, when X server exits, it will destroy
the allocated fb, making drm_crtc->fb points to NULL.
|
|
Since drm_bo_driver_init will be called in driver_load, we need to free
what it alloced when error to avoid memory leak.

Even if the TV encoder hasn't been fused off, we may not have a TV connector on
the platform. The BDB in the BIOS should give us this info in some cases.

Map the VBIOS (and therefore VBT) at init time for use by various output
initialization routines.

The kernel has removed nopage so move the old nopage codepaths into a compat vm file and switch to using the fault paths.
nopfn is on its way out in the future also, so we should switch to using fault
for that path as well soon

Turns out it's important to save/restore AR14 in particular.

Make both crtc and the command argument 32 bits to avoid any 32-on-64 compat
issues.

Chase the lock to it's new location.
|
|
Remove lock functions and use pci_map_rom() instead of pci_map_rom_copy().

|
forget to add it in the previous DVO porting patch.

This tries to automatically fetch a git revision string and if succeeds,
it #defines GIT_REVISION string macro. Packagers can override it by
'make GIT_REVISION=foo'.
Update Nouveau to use GIT_REVISION, if defined, instead of DRIVER_DATE
in struct drm_driver.

Ported from Xorg intel 2d driver. Changed interfaces definitions, which needed
to be changed later if other device wants to use these DVO stuff.
|
|
Add some branch prediction hints.
|
|
BO lock fixes.
|
|
Move unfenced checking into idle checking.
Never time out while waiting for software events like unmapped or unfenced.

|
Use the new TV property creation routine and fixup the set_property code
to actually do a mode set call when properties change.
|
|
It needs to take arguments from the caller about supported TV formats,
so declare it in drm_crtc.h and export it.
|
|
Cleanup some random cruft left over from the initial port.
