[PATCH v2 2/3] etnaviv: gallium driver for Vivante GPUs

[Emil Velikov]

Hi Christian,

There's a few nitpicks. Note that neither is a blocker so feel free to
send patches in the week(s) to come.

- There's a comment/documentation missing why we want/need
etnaviv_dri.so anywhere.
Please add something - be that in configure or a readme file in
{drivers,winsys}/etnaviv.

Pretty much anything will do ;-)

- This and 3/3 will need to update the "AC_ARG_WITH([gallium-drivers]"
help string.
Again - perfectly fine to address with separate commit.

CPP_SOURCES is empty. Please remove it (with later commit ?)

Don't use relative paths, use the below instead.

$(top_builddir)/src/gallium/auxiliary/libgallium.la

Iirc earlier commits had all the files (headers including) listed here.
Can we have those back please ?

We cannot used the VIV_FEATURE macro yet, but can we replace "1 << 2"
with the corresponding define ?

Thanks
