Add rom (only combios for now) parsing and use informations
retrieve instead of hardcoded table. Shuffle code around a
bit.

This avoids a sync flush when user-space has already programmed
and MI_FLUSH in the batchbuffer.

Yes, I'm quite aware "real" nv04 doesn't support this, hopefully the GPU
will just ignore those PGRAPH_DEBUG_3 bits on that hw.

bug 12108
|

This is necessary for AGP to work after running bios init scripts on nv3x, and
is seen in mmio traces of all cards (nv04-nv4x)
I'm not making the equivalent change to nv40_mc.c, as early cards (6200, 6800gt)
use the 0x000018XX PBUS and later cards use the 0x000880XX PBUS and I don't know
the effects of using the wrong one

Don't set the context as valid until it has been loaded

As DRM_DEBUG macro already prints out the __FUNCTION__ string (see
drivers/char/drm/drmP.h), it is not worth doing this again. At some
other places the ending "\n" was added.
airlied:- I cleaned up a few that this patch missed also

Flags pending validation were stored in a misleadingly named field, 'mask'.
As 'mask' is already used to indicate pieces of a flags field which are
changing, it seems better to use a name reflecting the actual purpose of
this field. I chose 'proposed_flags' as they may not actually end up in
'flags', and in an case will be modified when they are moved over.
This affects the API, but not ABI of the user-mode interface.

The casting is safe only when the list_head member is the first member of
the structure.

drivers/char/drm/mga_dma.c::mga_do_cleanup_dma() and I think there's a small
problem.
The variable is only used inside #if __OS_HAS_AGP which is fine, but all
that
ever happens is an assignment to the variable - it is never actually used
for
anything. The variable is nicely initialized to zero which is also what the
return statement at the end of function returns (always at the moment).
It looks to me like that function should be returning 'err' instead of
always
just returning 0. Here's a patch to do that.

Document parameters and usage for drm_bo_handle_validate. Change parameter
order to match drm_bo_do_validate (fence_class has been moved to after
flags, hint and mask values). Existing users of this function have been
changed, but out-of-tree users must be modified separately.
|
|
Add comments about the parameters to drm_bo_do_validate, along
with comments for the DRM_BO_HINT options. Remove the 'do_wait'
parameter as it is duplicated by DRM_BO_HINT_DONT_BLOCK.

When writing a relocation entry, make sure the target buffer is idle,
otherwise the GPU may see inconsistent data.
|
|
|

One of the costs of superioctl has been the need to perform relocations
inside the kernel. The cost of mapping the buffers to the CPU and writing
data is fairly high, especially if those buffers have been mapped and read
by the GPU.
If we assume that buffers don't move around very often, we can have the
client compute the relocations itself using the previous GPU address. When
that object doesn't move, the kernel can skip computing and writing the
updated data.
Here's a patch which adds a new field to struct drm_bo_info_req called
'presumed_offset', and a new DRM_BO_HINT_PRESUMED_OFFSET that is set when
this field has been filled in by the client.
There are two separate optimizations performed when the presumed_offset is
correct:
1. i915_exec_reloc checks to see if all previous buffer offsets were guessed
correctly. If so, there's no need for it to look at *any* of the
relocations for a buffer. When this happens, it skips the whole
relocation process, simply returning success.
2. i915_apply_reloc checks to see if the target buffer offset was guessed
correctly. If so, it skips mapping the relocatee, computing the
relocation and writing the value. If no relocations are needed, the
relocatee should never be mapped to the CPU, and so the kernel shouldn't
need to wait for any fences to pass.
