Subject: broadcom/vc5: Print the buffer name in simulator overflow checks.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=95873a184e735b37e39ad1ba5ce05391f27b52e2;p=mesa.git

broadcom/vc5: Print the buffer name in simulator overflow checks.

Revealed that I was writing past the TSDA, not the Z buffer as I expected.
