Subject: gallium/util: Use PIPE_TRANSFER_DISCARD_RANGE in pipe_buffer_write.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=65942e141fc3da760b53248eafdd876a45b592d4;p=mesa.git

gallium/util: Use PIPE_TRANSFER_DISCARD_RANGE in pipe_buffer_write.

Additionally, to discarding the whole buffer, use
PIPE_TRANSFER_DISCARD_RANGE in pipe_buffer_write when the
write covers only part of the buffer.
