target-mips: fix save_cpu_state() calls

2011-01-24T19:52:19+00:00

The rule is: - don't save PC if the exception is only triggered by softmmu. - save PC if the exception can be triggered by an helper. Fix a 64-bit kernel crash when loading modules. Signed-off-by: Aurelien Jarno (cherry picked from commit b835e919f022d768abdf00e8dc94f1a23fdcab15)

target-sparc: fix udiv(cc) and sdiv(cc)

2010-12-28T22:18:37+00:00

Since commit 5a4bb580cdb10b066f9fd67658b31cac4a4ea5e5, Xorg crashes on a Debian Etch image. The commit itself is fine, but it triggers a bug due to wrong computation of flags for udiv(cc) and sdiv(cc). This patch only compute cc_src2 for the cc version of udiv/sdiv. It also moves the update of cc_dst and cc_op to the helper, as it is faster doing it here when there is already an helper.

target-arm: fix bug in translation of REVSH

2010-12-27T20:38:05+00:00

The translation of REVSH shifted the low byte 8 steps left before performing an 8-bit sign extend, causing this part of the expression to alwas be 0.

vhost: error code

virtio: change set guest notifier to per-device

2010-10-12T21:09:52+00:00

When using irqfd with vhost-net to inject interrupts, a single evenfd might inject multiple interrupts. Implementing this is much easier with a single per-device callback to set guest notifiers. Signed-off-by: Michael S. Tsirkin (cherry picked from commit 54dd932128ae08d6a5a6668551508e30520b0f86)

eepro100: Add support for multiple individual addresses (multiple IA)

2010-10-12T21:09:45+00:00

I reviewed the latest sources of Linux, FreeBSD and NetBSD. They all reset the multiple IA bit (multi_ia in BSD) to zero, but I did not find code which sets this bit to one (like it is done by some routers). Running Windows guests also did not set this bit. Intel's Open Source Software Developer Manual does not give much information on the semantics related to this bit, so I had to guess how it works. The guess was good enough to make the router emulation work. Related changes in this patch: * Update naming and documentation of the internal hash register. It is not limited to multicast, but also used for multiple IA. * Dump complete configuration register when debug traces are enabled. * Debug output when multiple IA bit is set during CmdConfigure. * Debug output when frames are received because multiple IA bit is set, or when they are ignored although it is set.

virtio-net: unify vhost-net start/stop

2010-10-12T21:09:35+00:00

Move all of vhost-net start/stop logic to a single routine, and call it from everywhere. Additionally, start/stop vhost-net on link up/down: we should not transmit anything if user asked us to put the link down. Signed-off-by: Michael S. Tsirkin Acked-by: Alex Williamson

virtio: invoke set_status callback on reset

2010-10-12T21:09:26+00:00

As status is set to 0 on reset, invoke the relevant callback. This makes for a cleaner code in devices as they don't need to duplicate the code in their reset routine, as well as excercises this path a little more. In particular this makes it possible to unify vhost-net handling code with the following patch. Signed-off-by: Michael S. Tsirkin (cherry picked from commit e0c472d8c2795e523b0f9006dbe5bc22545c8300)
