From 75cacb128b2d39863a72f60cbefc0987cbcaf641 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Philippe=20Mathieu-Daud=C3=A9?= Date: Thu, 14 Jun 2018 20:39:35 -0300 Subject: [PATCH] hw/isa/smc37c669: Change the parallel I/O base to 378H MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit On the Alpha DP264 machine, the Cirrus VGA is I/O mapped in the 3C0H-3CFH range, thus I/O base used by the parallel device clashes, and since a4cb773928e the VGA is not working: (qemu) info mtree address-space: memory 0000000000000000-ffffffffffffffff (prio 0, i/o): system 00000801fc000000-00000801fdffffff (prio 0, i/o): pci0-io ... 00000801fc0003b4-00000801fc0003b5 (prio 0, i/o): vga 00000801fc0003ba-00000801fc0003ba (prio 0, i/o): vga 00000801fc0003bc-00000801fc0003c3 (prio 0, i/o): parallel ^^^ ^^^^^^^^ 00000801fc0003c0-00000801fc0003cf (prio 0, i/o): vga ^^^ 00000801fc0003d4-00000801fc0003d5 (prio 0, i/o): vga 00000801fc0003da-00000801fc0003da (prio 0, i/o): vga ... As there is no particular reason to use this base address (introduced in 7bea0dd434e), change to 378H which is the default on PC machines. Reported-by: Emilio G.
