2013-11-21mips jazz: do not raise data bus exception when accessing invalid addressesHervé Poussineau1-0/+24
MIPS Jazz chipset doesn't seem to raise data bus exceptions on invalid accesses. However, there is no easy way to prevent them. Creating a big memory region for the whole address space doesn't prevent memory core to directly call unassigned_mem_read/write which in turn call cpu->do_unassigned_access, which (for MIPS CPU) raise an data bus exception. This fixes a MIPS Jazz regression introduced in c658b94f6e8c206c59d02aa6fbac285b86b53d2c.

2013-08-28hw: Clean up bogus default boot orderMarkus Armbruster1-2/+0
We set default boot order "cad" in every single machine definition except "pseries" and "moxiesim", even though very few boards actually care for boot order, and "cad" makes sense for even fewer. Machines that care: * pc and its variants Accept up to three letters 'a', 'b' (undocumented alias for 'a'), 'c', 'd' and 'n'. Reject all others (fatal with -boot). * nseries (n800, n810) Check whether order starts with 'n'. Silently ignored otherwise. * prep, g3beige, mac99 Extract the first character the machine understands (subset of 'a'..'f'). Silently ignored otherwise. * spapr Accept an arbitrary string (vl.c restricts it to contain only 'a'..'p', no duplicates). * sun4[mdc] Use the first character. Silently ignored otherwise. Strip characters these machines ignore from their default boot order. For all other machines, remove the unused default boot order alltogether. Note that my rename of QEMUMachine member boot_order to default_boot_order and QEMUMachineInitArgs member boot_device to boot_order has a welcome side effect: it makes every use of boot orders visible in this patch, for easy review.

2013-08-08mips: revert commit b332d24a8e1290954029814d09156b06ede358e2Aurelien Jarno1-2/+3
Now that this code path is not triggered anymore during the tests, revert commit b332d24a8e1290954029814d09156b06ede358e2. Booting a MIPS target without kernel nor bios doesn't really make sense. At the same time replace fprintf(stderr, ...) by error_report(). Reviewed-by: Andreas Färber <afaerber@suse.de> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2013-04-08hw: move headers to include/Paolo Bonzini1-11/+11
Many of these should be cleaned up with proper qdev-/QOM-ification. Right now there are many catch-all headers in include/hw/ARCH depending on cpu.h, and this makes it necessary to compile these files per-target. However, fixing this does not belong in these patches.
