We no longer need to use it to protect against shared ringbuffer access.
|
|
Use GEM for ring buffer setup and framebuffer allocation. This means reworking
the hardware status page stuff a bit (just use the basic range allocator for
vram for now) and #ifdef'ing out the TTM & DRI2 code. Works well enough to
load/unload several times and display fbcon on my T61 (though there's still
some unexplained console corruption).

This is the create (may want location flags), pread/pwrite/mmap
(performance tuning hints), and set_domain (will 32 bits be enough for
everyone?) ioctls. Left in the generic set are just flink/open/close.
The 2D driver must be updated for this change, and API but not ABI is broken
for 3D. The driver version is bumped to mark this.

They are not unnecessary since the kernel's the only thing touching the ring.
|
|
Use new GEM based ring buffer initialization. Still need to init GEM & use it
for framebuffer allocation etc.

This requires that the X Server use the execbuf interface for buffer
submission, as it no longer has direct access to the ring. This is
therefore a flag day for the gem interface.
This also adds enter/leavevt ioctls for use by the X Server. These would
get stubbed out in a modesetting implementation, but are required while
in an environment where the device's state is only managed by the DRM while
X has the VT.

Passed the compile test; it's ready to ship.

Port over EDID quirks from X.Org so we can handle more monitors. This meant
adding size info to the drm_display_mode struct, but other than that the
changes were isolated to the DRM EDID handling code (as they should be).
|
|
|
|
The driver can know what hardware requires MI_BATCH_BUFFER vs
MI_BATCH_BUFFER_START; there's no reason to let user mode configure this.
|
|
Without the user IRQ running constantly, there's no wakeup when the ring
empties to go retire requests and free buffers. Use a 1 second timer to make
that happen more often.
|
|
Instead of throttling and execbuffer time, have the application ask to
throttle explicitly. This allows the throttle to happen less often, and
without holding the DRM lock.

better place to store them.

A check in drm_sysfs_connector_remove was supposed to allow it to be called
even with unregistered objects, to make cleanup paths a little simpler.
However, device_is_regsitered didn't always seem to return what we thought it
would, so we'd sometimes end up leaving objects lying around rather than
unregistering them.
Fix this situation up by requiring devices to be registered before being
removed. Any problems resulting from this change should be easier to track
down than the alternative (which is leaving kobjects registered after unload).

remove fb callbacks, just probe into the driver to sort it out

Better to initialize all the struct fields to 0. Also more consistent with
other output init routines.
|
|
We need to initialize the edid_blob_ptr to NULL when we init a connector,
otherwise drm_mode_connector_update_edid_property may think there's a valid
EDID lying around and try to destroy it, causing a crash.

struct_mutex cannot be held while blocking on DRM lock.
|
|
Idea being if you want to add new crtc/output/encoder dynamically later,
you just increase the generation counter and userspace should re-read
all the resources

Move TTM code into the driver
|
|
This compares the clocks after converting to fb pico timings so we
get the same answer if the X and fb modes are the same.
|
|
Without kernel modesetting, this requires cooperation of the userspace
modesetting driver. We may have to leave the vblank interrupt enabled otherwise
to avoid problems.
