This is the threshold after which drm_intel_bufmgr_check_aperture_space
returns -ENOSPC, signalling that it thinks an execbuf is likely to fail
and we need to roll back and flush the batch.
We'll need this when we rewrite aperture space checking, shortly.
In the meantime, we can also use it in GLX_MESA_query_renderer.

I'm about to make brw_emit_reloc do actual work, so everybody needs

This renames intel_batchbuffer_reloc to brw_emit_reloc and changes the
parameter naming and ordering to match drm_intel_bo_emit_reloc().
For now, it's a trivial wrapper that accesses batch->bo. When we
rework relocations, it will start doing actual work.
target_offset should be expanded to a uint64_t to match the kernel,
but for now we leave it as its original 32-bit type.

This is only useful when doing an incoherent CPU mapping of the current
scanout buffer. That's a terrible plan, so we never do it. We always
use an uncached GTT map.
So, this is useless. Drop the code.

This functionality was added by libdrm commit
743af59669386cb6e063fa4bd85f0a0b2da86295 (intel: make bufmgr_gem
shareable from different API) in an attempt to solve libva/mesa buffer
sharing problems. Specifically, this was working around an issue hit
by Chromium, which used the same drm_fd for multiple APIs, and shared
buffers between them.
This code attempted to work around that issue by using the same bufmgr
for both libva and Mesa. It worked because libdrm_intel was loaded by
both libraries. However, now that Mesa has forked, we don't have a
common library, and this code cannot work.
The correct solution is to have each API open its own file descriptor
(and get a corresponding buffer manager), and then use PRIME export
and import to share BOs across those APIs. Then the kernel can manage
those shared resources. According to Chris, the kernel will pass back
the same handle for a prime FD if the lookup is from the same device FD.
We believe Chromium has since moved to this model.
In Mesa, there is already only one screen per FD, and so there will
only be one bufmgr per FD. We don't need any of this code.
v2: Add a big warning comment written by Chris Wilson.

No performance data has been gathered about this choice. I just don't
want that many hash tables. Chris points out that this is not
performance critical - we should not be recreating that many handles
from scratch. In the past we used a linear list, which became
unreasonable in stress tests that used hundreds of thousands of BOs.
In real usage, it shouldn't matter that much.

This moves the PCI ID detection to intel_screen.c and makes
drm_bacon_bufmgr_gem_init() take a devinfo pointer.
We also drop the HAS_LLC query stuff - devinfo has that info already,

Using drm_intel_* as a prefix is hazardous - we don't want to conflict
with the actual libdrm_intel symbols. In particular, I think we could
get into trouble during the final megadrivers linking.
So, rename everything to an different yet arbitrary prefix. bacon and
intel are the same number of characters, so we don't have to reindent
the world. It's also an homage to Ian's "Bacon Trail" platform.
I was going to use "drm_relic" to poke fun at libdrm being ancient,
and so we could explain the name with a "historical reasons" pun,
but it sounds too much like ralloc.

i965 doesn't use drm_intel_get_aperture_sizes(), so we can delete
support for it. This avoids a build dependency on libpciaccess.
Chris also notes:
"There's a really old bug that hopefully has been closed already
(although as far as I can tell, it has never been fixed) about
how using libpciaccess from libdrm_intel breaks the world (since
libpciaccess uses a singleton that is torn down at the first request
rather than upon the last user)."
This bug should go away in two commits when we switch over to our
internal copy of libdrm_intel.

Using an incoherent CPU map on the active scanout buffer is really
sketchy - we may need extra flushing via GEM_SW_FINISH, or using
drmModeDirtyFB() and kernel commit a6a7cc4b7db6d (4.10+).
Chris suggests "never ever do that", which seems like a wise plan!
intel_miptree_map_raw() uses CPU maps on linear buffers.
Having a linear scanout buffer should be really rare, and mapping the
front buffer should be similarly rare. Together, it should basically
never happen. But, in case it does somehow...make sure that mapping
the scanout buffer always goes through an uncached GTT map.

On modern systems with 4GB apertures, the size in bytes is 4294967296,
or (1ull << 32). The kernel gives us the aperture size as a __u64,
which works out great.
Unfortunately, libdrm "helpfully" returns the data as a size_t, which
on 32-bit systems means it truncates the aperture size to 0 bytes.
We've happily reported this value as 0 MB of video memory via
GLX_MESA_query_renderer since it was originally exposed.
This patch bypasses libdrm and calls the ioctl ourselves so we can
use a proper uint64_t, avoiding the 32-bit integer overflow. We now
report a proper video memory size on 32-bit systems.
Chris points out that the aperture size (CPU mappable size limit)
isn't really the right thing to be checking. But libdrm_intel uses
it to fail execbuffer, so it is an actual limit for now. Once that's
fixed we can probably move to something else. In the meantime, fix
the obvious typecasting bug.

Interestingly, acc. to testing with GTAⅣ, though binding of null shader happens

The idea is taken from radeonsi. The code lacks some checks for null vs,
and I'm unsure about some changes against that, so I left it in place.
Some statistics for GTAⅣ:
Average tesselation bind skip per frame: ≈350
Average geometric shaders bind skip per frame: ≈260
Skip of binding vertex ones occurs rarely enough to not get into per-frame
counter at all, so I just gonna say: it happens.
