[Mesa-dev] [PATCHv3 0/4] Separate device from driver vendor

[Giuseppe Bilotta]

OpenCL (as opposed to OpenGL) has separate vendor strings for the
implementation/driver/platform and the device. CL_PLATFORM_VENDOR
is akin to the GL_VENDOR string, while CL_DEVICE_VENDOR is supposed to
return the actual device vendor.

(For example, the AMD OpenCL platform returns GenuineIntel as
CL_DEVICE_VENDOR for an Intel CPU.)

This patchset separates (where possible/necessary) the device vendor
from the driver vendor in existing gallium drivers, and makes clover use
the newly introduced device vendor for CL_DEVICE_VENDOR queries.

For some drivers, get_device_vendor is mapped to get_vendor: this
is usually done because get_vendor already returns an appropriate string,
except in the case of softpipe and llvmpipe, where the returned vendor
should be the CPU vendor (and I don't know enough about the structure
of these driver to extract the information 8-P)


Changes since v2:

* freedreno defined its device vendor function, but didn't actually use it
* the get_device_vendor entrypoint has been moved right after get_vendor,
  and RST documentation has been added


Changes since v1:

* vc4's get_device_vendor maps to vc4_screen_get_vendor() instead of the
  non-existing vc4_screen_get_device_vendor();
* freedreno should report Qualcomm, as device vendor, so it needs
  an actual implementation of get_device_vendor distinct from that of
  get_vendor.


Giuseppe Bilotta (4):
  Whitespace cleanup
  Introduce get_device_vendor() entrypoint for pipes
  Implement get_device_vendor() for existing drivers
  Clover: use get_device_vendor instead of get_vendor
