# AP: patch test 50: 22-bit mapping carry propagation ------------------------
|
|
# The test does an access to 17000000, the first word of the UNIBUS
|
|
# window. It expects CPUERR 020 because UBMAP is disabled in MMR3.
|
|
# w11 doesn't simulate the UNIBUS window and has a memory hole instead.
|
|
# So access aborts with NXM instead of timeout.
|
|
# Patch the testing instruction to it expects NXM in CPUERR.

# AP: patch test 122: KT BEND ------------------------------------------------
|
|
# Tests MMU vs NXM,ODD,RED behavior
|
|
# The 1st part tests NXM vs MMU. On a KB11-C handles NXM earlier then MMU (!)
|
|
# On a KB11-E MMU takes precedence (as one expects and SimH, e11, and w11 do).
|
|
# It is tempting to patch the code such that KB11-E behavior is tested. But
|
|
# that code path is buggy, doesn't clear MMR0, and causes a followup error in
|
|
# the following test (at 076414) because MMR0 isn't cleared. Therefore, the
|
|
# patch just inhibits the error print, and MMR0 is cleared afterwards.

# The 2nd part tests RED vs MMU. On a 11/70 the MMR0 abort bits are not set
|
|
# in case of a stack in a non-resident page with an address below STKLIM.
|
|
# w11 does set the MMR0 abort bit, and take a fatal stack error.
|
|
# Patch test to ignore that (beq 10$ -> br 10$) MMR0 abort bit is set.
