2009-02-28Implement HIORblueswir1
A real 970 CPU starts up with HIOR=0xfff00000 and triggers a reset exception, basically ending up at IP 0xfff001000. Later on this HIOR has to be set to 0 by the firmware in order to enable the OS to handle interrupts on its own. This patch maps HIOR to exec_prefix, which does the same thing internally in qemu already. It replaces the previous patch that changed the 970 initialization constants, as this is the clean solution to the same problem.

2009-02-28Change default werror semantics from "report" to "enospc"aliguori
Practically speaking, "report" causes a lot of issues when encountering a host ENOSPC error. Switch to "enospc" as the default werror semantics. All host errors other than ENOSPC will be reported to the guest. ENOSPC will cause the VM to stop. Asynchronous notifications are needed to inform management tools that some action should be taken but stopping the VM is at least better than undefined behavior in the guest.

Resent with fixed formatting. This patch adds two new command line options: -chroot <dir> -runas <user> This is useful for running qemu as an unprivileged user in a chroot jail. To avoid having to populate the jail, chrooting happens right before the start of guest execution.

2009-02-27Missing cirrus_invalidate_region() in cirrus_do_copy() (Brian Kress)aliguori
After doing a video to video copy, cirrus_do_copy() in cirrus_vga.c does a conditional call to cirrus_invalidate_region() with an "if (!notify)" test. However at this point the blt has already been done so it seems like this call should be made unconditionally.

2009-02-21Avoid thundering herd problemmalc
Broadcast was used so that the I/O threads would wakeup, reset their ts values and all but one go to sleep, in other words an optimization to prevent threads from exiting in presence of continuing I/O activity. Spurious wakeups make the looping around cond_timedwait with ever reinitialized ts potentially unsafe and as such ts in no longer reinitilized inside the loop, hence switch to signal is warranted and this benefits of this particlaur optimization are lost. (It's worth noting that timed variants of pthread calls use realtime clock by default, and therefore can hang "forever" should the host time be changed. Unfortunatelly not all host systems QEMU runs on support CLOCK_MONOTONIC and/or pthread_condattr_setclock with this value) git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@6632 c046a42c-6fe2-441c-8c8c-71466251a162

2009-02-18Fix cpu_physical_memory_rw() for 64-bit I/O accessesaurel32
KVM uses cpu_physical_memory_rw() to access the I/O devices. When a read or write with a length of 8-byte is requested, it is split into 2 4-byte accesses. This has been broken in revision 5849. After this revision, only the first 4 bytes are actually read/write to the device, as the target address is changed, so on the next iteration of the loop the next 4 bytes are actually read/written elsewhere (in the RAM for the graphic card). This patch fixes screen corruption (and most probably data corruption) with FreeBSD/amd64. Bug #2556746 in KVM bugzilla.

2009-02-16Fix hardware accelerated video to video copy on Cirrus VGA (Brian Kress)aliguori
cirrus_do_copy() in hw/cirrus_vga.c seems to make some incorrect assumptions about video memory layout. It tries to convert addresses to coordinates assuming that one row of data is (width * depth) bytes long. The correct way seems to be to use the pitch fields in the CirrusVGAState structure instead. Without this patch, I get lots of screen corruption when I try to drag a window under X as it's passing the wrong coordinates to the display surface for the copy. With this patch I can drag a window with no screen corruption.
