llvmpipe: add POWER8 portability file - u_pwr8.h

This file provides a portability layer that will make it easier to convert
SSE-based functions to VMX/VSX-based functions.

All the functions implemented in this file are prefixed using "vec_".
Therefore, when converting from SSE-based function, one needs to simply
replace the "_mm_" prefix of the SSE function being called to "vec_".

Having said that, not all functions could be converted as such, due to the
differences between the architectures. So, when doing such
conversion hurt the performance, I preferred to implement a more ad-hoc
solution. For example, converting the _mm_shuffle_epi32 needed to be done
using ad-hoc masks instead of a generic function.

All the functions in this file support both little-endian and big-endian
but currently the file is build only on POWER8 LE machine.

All of the functions are implemented using the Altivec/VMX intrinsics,
except one where I needed to use inline assembly (due to missing
intrinsic).

- Use vec_vgbbd instead of __builtin_vec_vgbbd

region from the subnr.

In the past, we adopted a vec4-centric approach of specifying subnr of
0 or 4 and a swizzle, then having brw_eu_emit.c convert that to a proper

This patch changes brw_eu_emit.c to use subnr and swizzle directly,

u_upload_mgr: pass alignment to u_upload_alloc manually

The fixed alignment of u_upload_mgr will go away.
This is the first step.

The motivation is that one u_upload_mgr can have multiple users,
each allocating from the same buffer, but requiring a different alignment.

8 years agou_upload_mgr: rework the application of alignment

u_upload_mgr: rework the application of alignment

The function only aligned the size, but not the offset.
The offset was aligned only when the previous suballocation was aligned.
That yielded the correct offset alignment if the alignment was constant
for all suballocations.

Instead, directly align the offset, but allow an unaligned size.
There is no change in behavior, because the alignment is constant
at the moment.

This a prerequisite for allowing a variable alignment for suballocations.

First off, we can't flush in the middle of a command. Secondly
requesting the extra push space might cause a flush to happen. If that
flush happens, we'd have to do the PUSH_REFN again. So instead do
PUSH_REFN after the push space request. This helps avoid rare crashes
