Wondering how you'll feel about "check your distro and add svga to the
gallium-drivers array" style of instructions ?
I'm afraid I don't quite understand what you're saying there. Can you
elaborate?
Rather than walking through the requirements, configure and make/make
install steps, just forward people to the distro specific wiki on "how
to build mesa/kernel" and explicitly mention the differences:
mesa:
- XA must be enabled: --enable-xa
- svga must be listed in the gallium drivers: --with-gallium-drivers=svga...
kernel:
- Set DRM_VMWGFX
others...
I guess I've never seen those wikis. I'd have to search for them, but I
really don't have the time now.
We actually have an in-house shell script that installs all the pre-req
packages, pulls the git trees, builds and installs for a variety of
guest OSes. But it has some VMware-specific stuff that I'd have to trim
out before making public.
Related: does the upstream [1] vmwgfx module work well when combined
with upstream core drm across different versions ? Considering how
well Thomas is handling upstreaming shouldn't the module from the
kernel be recommended ?
Either should be fine at this point but the build instructions cover the
case of one having an older distro that may not have the GL3-enabled
kernel module already.
For example some of us had nasty experiences where versions of vmware
player/workstation ships/builds/uses kernel modules which "clash" with
the ones already bundled in the kernel package. With "clash" - there
is no guarantee whether the upstream or downstream module gets loaded,
and due difference in the symbols provided one does encounter
"function_foo() error Invalid argument" type of messages, and
ultimately things just not working.
I don't think I've ever had much trouble with that. The host-side Linux
kernel modules aren't really my area so I can't say much about that.
