Subject: Add requested size to r300RefillCurrentDmaRegion.
X-Git-Tag: 062012170305~20214
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b6c2a6a0f295c078efc4737337ad67deaa7cee0a;p=profile%2Fivi%2Fmesa.git

Add requested size to r300RefillCurrentDmaRegion.

This way we no longuer have the fixed RADEON_BUFFER_SIZE.
Anyway function calling AllocDmaRegion should check if this
succeed and fail gracefuly if not (see bug 8348).
