The old code increments the command stream size by another kbyte, but does
not make sure that the requested packet size fits into the stream. The patch
ensures that the whole next packet fits there and rounds the allocated size to
a power of two.

Not sure what intptr_t was up to here.

This reverts commit 0a732983f059c353b267b6bf877e1f0eea4e033f.
Paul Nieminen and Dave Airlie pointed out on IRC that this shouldn't be
necessary. I was seeing visual corruption in X before I made this change, but
I can't reproduce that anymore so it was probably an unrelated issue.

This allows users to eliminate explicit bo_wait calls before bo_map calls.

airlied: modified the interface to drop busy return value, just return
it normally, also fixed int->uint32_t for domain

Using this call in OUT_BATCH_TABLE reduces radeonEmitState cpu usage from
9% to 5% and emit_vpu goes from 7% to 1.5%. I did use calgrind to profile
gears for cpu hotspots with r500 card.

GCC did war about optimization not possible because possible forever loop.

This caches the mapping and just use mapping as a sync point
|
|
This ports a lot of the space checking code into a the common
library, so that the DDX and mesa can use it.
|
|
We always realloc at least 0x1000 dwords (page on most system)
when growing the cs buffer this is to avoid having to realloc
at each cs_begin.
|
|
This should use ndw not cdw, using cdw leads to realloc alignment going wrong
|
|
|
|
the DDX does this and used to handle it internally
|
|
requires --enable-radeon-experimental-api for now

This reverts commit 6656db10551bbb8770dd945b6d81d5138521f208.
We really just want the libdrm and ioctl bits, not all the driver
stuff.

BO are referenced once by reloc to make sure that they not destroyed
before we get a chance to flush the cmd stream, so we need to unreference
them once in cs submit or cs erase if cs i never submitted so bo can
be destructed.
|
|
To keep record of bo activities and print them when necessary,
should help in tracking unbalanced ref/unref calls.
|
|
Relocation now consist of the following informations (in this order) :
handle buffer object handle identifier
start_offset start offset of first data of the buffer object used by the cs
end_offset end offset of last data of the buffer object used by the cs
read_domain read domain (either VRAM, or GTT as GPU is invalid for CS)
write_domain write domain (either VRAM, or GTT as GPU is invalid for CS)
flags flags used for further optimization (like discard previous
buffer content or forget buffer content after cs which can
help in avoiding moving content in or out)
