Description Gert Wollny 2018-12-31 10:45:27 UTC

With the commit db77573d7bae90e an error was introduced that results in errors with respect to buffer flushing when running dEQP test cases, e.g.: 

dEQP-GLES31.functional.debug.error_filters.case_3 
dEQP-GLES31.functional.debug.error_group.case_3
dEQP-GLES31.functional.debug.async.case_6_log
dEQP-GLES3.functional.state_query.buffer_object.buffer_access_flags_getbufferparameteri
dEQP-GLES3.functional.state_query.buffer_object.buffer_access_flags_getbufferparameteri64

In these cases the virglrenderer host will abort with a message 

vtest_transfer_put2 called vtest_block_read which failed (-14)

Tested host virglrenderer git-ea97380ec8987
