From c0b782476e5a305a444a149eb733ecc7f06a35af Mon Sep 17 00:00:00 2001 From: Arthur Hanson Rasmusson Date: Wed, 30 Sep 2026 01:52:57 -0400 Subject: guest-diag: bpz7 - split membar hook failure into lookup vs ucode load Host oracle (real TU104, 570.211): FUN_0035a4d0(0x13,7,5) succeeds because the 3-entry remap table at 0x3dc5b80 maps (7,5)->(7,0); the guest has the same table. bpz7 breaks before/after the lookup and the FUN_00e21850 ucode load in FUN_005d7e70 to see which one fails in the guest. Also fix invd.py's lookup address (0x25a4d0, not 0x35a4d0). --- tools/guest-diag/invd.py | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'tools/guest-diag/invd.py') diff --git a/tools/guest-diag/invd.py b/tools/guest-diag/invd.py index 1fc8491..313daa3 100644 --- a/tools/guest-diag/invd.py +++ b/tools/guest-diag/invd.py @@ -57,7 +57,7 @@ if dev: (q or 0, (q or 0) & 0xffffffff, (q or 0) >> 32)) print(" state+0xc54 = 0x%x" % (r32(st + 0xc54) or 0)) -f = base + 0x35a4d0 +f = base + 0x25a4d0 def lookup(chip, rev): -- cgit v1.2.3
