# verify-amiga-fastram.sh - a surface in Fast RAM draws and copies as one in
|
|
# chip RAM does.
|
|
#
|
|
# The Amiga puts a surface's planes in chip RAM, where the blitter that does
|
|
# its fills and copies can reach them; once chip RAM has run out, a surface
|
|
# other than the stage goes in Fast RAM, and its fills and copies run on the
|
|
# CPU (src/amiga/hal.c, jlpSurfaceAllocPortData). FASTRAM (tests/amiga/
|
|
# fastRam.c; make -f make/amiga.mk build/amiga/test/Fastram) runs under
|
|
# FS-UAE on an A500 with 2 MB of Fast RAM: it fills chip RAM with ballast,
|
|
# makes a surface, which must land in Fast RAM, and checks that the same
|
|
# drawing and copies on it and on a chip surface hash the same.
|
|
#
|
|
# Usage: scripts/verify-amiga-fastram.sh
|
|
# Env: TIMEOUT seconds to wait for the program (default 120)
|
|
# Exit: 0 PASS, 1 FAIL, 2 SKIP (FS-UAE or the Kickstart not installed)
