Subject: mesa/bufferobj: use mapping range in BufferSubData.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e891f7cf55f2f3e3d37ece12e5c64f4be70e3845;p=mesa.git

mesa/bufferobj: use mapping range in BufferSubData.

According to GL4.5 spec:
An INVALID_OPERATION error is generated if any part of the speci-
fied buffer range is mapped with MapBufferRange or MapBuffer (see sec-
tion 6.3), unless it was mapped with MAP_PERSISTENT_BIT set in the Map-
BufferRange access flags.

So we should use the if range is mapped path.

This fixes:
GL45-CTS.buffer_storage.map_persistent_buffer_sub_data
