Just a little bit more debug information
Signed-off-by: Thomas White <taw@bitwiz.org.uk>

This increases the amount of memory exposed via the framebuffer.
This should eventually allow an fbdev-based DDX or a KMS DDX to
run on the same kernel, albeit suboptimally.

This removes a bogus check of var->pixclock. With KMS, this value
is not relevant.

This seems to fix the kernel-level suspend/resume. There remains a problem
which causes Xorg to crash on resume.

Fix a whitespace error introduced by the earlier debug stuff.

This uses the "stopgap" method implemented earlier.

...because the clock(s) must be running while we talk to the chip.

This fixes the scanout timing conversion so that it works.

This adds a stopgap measure to permit manipulation of the LCD controller
chip in the absence of an fb notifier chain. It also adds some messing
around with the DPMS stuff.

This also alters some debug lines.

This adds some missing bits and pieces to make most of the KMS
initialisation flow work.`

This adds more of the bare bones for KMS, to be fleshed out later.

This just tidies up the Glamo Kconfig file a bit.

This reuinites the "framebuffer" and "work" VRAM areas. With KMS, both roles will be done
by one pool of memory.

This implements the ioctl used for mapping GEM objects into memory.
This needs a unit test in glamo-dri-tests, but for the time being appears to
make X.org less segfaulty.

This allows command sequences to make use of buffer objects by providing
their GEM handles.
It also reorganises the code a bit, and adds a lot of missing security stuff.

This fixes things which were broken after the previous commit.
VRAM allocation now appears to work.

Reinitialise the command queue on resume, so the fun can continue...

This removes a lot of debugging. We can't afford to splurge out a
page of printk()s on every command submission.

We must enable the clock divider for the 2D engine in order for
anything interesting to happen. Well, duh.

This just moves the engine enabling calls around a bit.

This implements resetting of the command queue engine.

This is just brought across from xf86-video-glamo

This allows glamo_cmdq_wait() to timeout.
We will probably need to substitute this for something better later on, but for the
time being I wanted to avoid a deadlock if the command queue never cleared.

Tidy up the code in glamodrm_probe by doing glamodrm->gdrm
Pass 'gdrm' to glamo_cmdq_init, not glamo_core (d'oh!)
Enable the command queue engine at the start

This fixes the licence text at the top of glamo-cmdq.c, noting that code from

Distributions that use Xorg will not need the workaround at
all and now they can disable it.
Updated configurations to enable it by default.
