The CL CTS queries the max allocation size, and then attempts to
allocate buffers of that size. If not enough contiguous RAM/VRAM is
available, this causes errors in the radeon kernel module due to
inability to allocate the required memory.
It's a bit of a hack, but experimentally on my system, I can use ~3/4
of the card's VRAM for a single global/constant buffer allocation given
current GUI/compositor use.
For a 1GB Pitcairn (HD7850) this gets me from the reported clinfo values of:
Global memory size 2143076352 (1.996GiB)
Max memory allocation 1500153446 (1.397GiB)
Max constant buffer size 1500153446 (1.397GiB)
To:
Global memory size 2143076352 (1.996GiB)
Max memory allocation 751619276 (716MiB)
Max constant buffer size 751619276 (716MiB)

This updates the Gen4-5 code to use a line end cap width of 0.5
for non-smooth lines, and 1.0 for smooth lines - which is what we
do on Gen6+.

This unifies the Gen4-5 and Gen6+ line width calculations.
I believe it also fixes a bug - we weren't rounding the line width
to the nearest integer. The GL 4.5 (and GL 2.1) specs "Wide Lines"
section says:
"The actual width of non-antialiased lines is determined by rounding
the supplied width to the nearest integer, then clamping it to the
implementation-dependent maximum non-antialiased line width."
We don't need to care about _NEW_MULTISAMPLE here because multisampling
doesn't exist on Gen4-5, so the state shouldn't change.

This effectively reverts Robert Ellison's 2009 commit
cc8afbd386.
I'm not seeing any GL spec text indicating that UPPER won't work.
On Gen6+, this bit moved to 3DSTATE_WM as a single bit, controlling
UPPER_LEFT vs. UPPER_RIGHT. There is no way to request LOWER_RIGHT,
so UPPER_RIGHT is the best you can do.
In the G45 docs, it's marked as "Reserved" as well, but we just
decided to use it anyway.
This patch unifies the behavior between Gen4-5 and Gen6+.
Note that this is separate from point sprite texcoord behavior.

Modern GL specifications say that the point size should be 1.0 when
gl_PointSize is unwritten and the last enabled stage is a geometry
or tessellation shader. If it's a vertex shader, though, both the
GL specs and ES 3.0 spec say that it's undefined - so since Gen4-5
only support vertex shaders, there's no actual requirement to do this.
Since there is a cost associated (an extra dirty bit, which may cause
SF_STATE to be emitted more often), it may not be a good idea.
The real benefit is that it makes all generations behave identically.
And that seems somewhat nice...

Apparently, Nanhai made the Gen4-5 point size calculations round to the
nearest integer in commit 8d5231a358,
"according to spec". When Eric first ported the driver to Sandybridge,
he did not implement this rounding.
In the GL 2.1 and 3.0 specs "Basic Point Rasterization" section, it does
say "If antialiasing and point sprites are disabled, the actual width is
determined by rounding the supplied width to the nearest integer, then
clamping it to the implementation-dependent maximum non-antialised point
width."
In contrast, GL 3.1 and later do not appear to contain this rounding.
It might be reasonable to round, given that we only implement GL 2.1.
Of course, if we were to do that, we should actually implement the AA
vs. non-AA distinction. Brian added an XXX comment reminding us to fix
this 10 years ago, but it never happened.
I think a better plan is to follow the newer, unrounded behavior. This
is what we do on Gen6+ and it passes all the relevant conformance tests.

For each texture/image handles, we need to allocate a new
buffer for the bindless descriptor. But when the number of
buffers added to the current CS becomes high, the overhead
in the winsys (and in the kernel) is important.
To reduce this bottleneck, the idea is to suballocate the
bindless descriptors using a slab similar to the one used
in the winsys.
Currently, a buffer can hold 1024 bindless descriptors but
this limit is arbitrary and could be changed in the future
for some reasons. Once a slab is allocated the "base" buffer
is added to a per-context list.
