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.
|
|
This splits a lot of the core modesetting code out into a file of
helper functions, that are only called from themselves and/or the driver.
The driver gets called into more often or can call these functions from itself
if it is a helper using driver.
I've broken framebuffer resize doing this but I didn't like the API for that
in any case.

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.
|
|
To avoid bo memory manager being inited twice, it will be called
at firstopen when modeset is not enabled.

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.

moving modeset init code into one function and correct error
handling druing i915 init
|
|
We need to alloc a hw status page bo for G33 if modeset is enabled since the 2D
driver can't alloc gfx memory when working in drm modeset.
|
|
Fixup workqueue creation error handling and make sure we destroy the queue on
unload.
|
|
Map the VBIOS (and therefore VBT) at init time for use by various output
initialization routines.
|
|
Since it'll be freed at unload time, we should alloc devname rather than
pointing to the DRIVER_NAME string.
|
|
If the driver is 'modeset' enabled, it'll register it's interrupt
handler at load time. Set the devname in this case so that
/proc/interrupts makes sense.

if we are unloading the module, there is no master so therefore no lock

This change adds a driver feature that for i915 is controlled by a module
parameter. You now need to do insmod i915.ko modeset=1 to enable it the
modesetting paths.
It also fixes up lots of X paths. I can run my new DDX driver on this code
with and without modesetting enabled

We may want to make the old i915 memory manager obsolete eventually, and in the
meantime the takedown causes problems on unload so remove it for now.

Mostly removing typedefs that snuck into the modesetting code and
updating to the latest TTM APIs. As of today, the i915 driver builds,
but there are likely to be problems, so debugging and bugfixes will
come next.

Lots of changes to merge with alanh's latest stuff:
o fix use of fb->pitch now that it has the right value
o add new helper for finding the CRTC given an FB
o fix new fb_probe/fb_remove functions to take a CRTC
o fixup callers of new FB routines
o port drm_fb changes to intel_fb
o check for errors after creating fb buffer object
o go back to using cfb_imageblit since the accel stubs aren't ready

Add new FB hooks to the drm driver structure and make i915 use them for an
Intel specific FB driver. This will allow acceleration and better handling
of the command stream.

remove i915_driver_load fb related stuff. Add a small helper for setting up

We need to keep a list of user created fbs to nuke on master exit.
We also need to use the bo properly.

allocation correctly, and use drm_mem_reg_iomap to map ring buffer object.
|
|
When the kernel driver is loaded it sets up a lot of stuff..
it tears down the same stuff on unload.
This add a new map type called DRM_DRIVER which means the driver will clean the mapping up
and fix up the map cleaner
