Track named objects in /proc/dri/0/gem_names.
Track total object count in /proc/dri/0/gem_objects.
Initialize device gem data.
return -ENODEV for gem ioctls if the driver doesn't support gem.
Call unlock_page when unbinding from gtt.
Add numerous misssing calls to drm_gem_object_unreference.
|
|
Names are just another unique integer set (from another idr object).
Names are removed when the user refernces (handles) are all destroyed --
this required that handles for objects be counted separately from
internal kernel references (so that we can tell when the handles are all
gone).
|
|
Now that drm_gem_object has a drm_driver * in it, functions don't need both
parameters.
|
|
When pinning buffers, or using execbuffer, allow the application to specify
the necessary aperture allocation alignment constraints.

mixed 32/64 bit systems need 'special' help for ioctl where the user-space
and kernel-space datatypes differ. Fixing the datatypes to be the same size,
and align the same way for both 32 and 64-bit ppc and x86 environments will
elimiante the need to have magic 32/64-bit ioctl translation code.

krefs are way easier than a custom-coded spinlock+int combo.

Fix some utterly bonged loop while we were staring at it.

Turns out it's important to save/restore AR14 in particular.
|
|
It's not really a graphics memory allocator, just something to track ranges
of address space. It doesn't involve actual allocation, and was consuming
some desired namespace.

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

On first looking at it I assumed it was an aspect of the ttm backend as a
whole rather than specific allocations from a backend.

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.
|
|
Start i at -1 so that the masking works right.
|
|
Some fields had snuck into the drm_output structure. Put them back and
fill in more stuff from the EDID block.
|
|
Now that we can allocate load detect pipes, we can perform TV out load
detection correctly. Call the new routines and enable proper TV
detection.
|
|
TV out needs to do load detection, which means we have to find an
available pipe to use for the detection. Port over the pipe reservation
code for this purpose.
