[Qemu-devel] [PATCH 3/3] vnc/spice: add set_passwd monitor command.

Re: [Qemu-devel] [PATCH 1/1] iscsi: add iSCSI block device support

I don't really see the point of this. It's implemented as a protocol, and thus the bottom of the qemu protocol stack. So we might get SCSI commands in from the guest, decode them, just to re-encode them again and send them off to the network all inside qemu. Do you have any performance numbers s

[Qemu-devel] [PATCH 0/3] vnc/spice: add monitor commands to change+expire passwords.

Re: [Qemu-devel] [PATCH 1/5] block: Add top level BSG support

Nick, can we wait a bit with this series? With the threadlets currently pending for inclusion I can get my rewrite of the generic-generic to not abuse the qemu block layer out of the closet again, which should simplify a lot of the things you're touching here.

[Qemu-devel] [PATCH 1/6] ARM: linux-user: Correct size of padding in target_ucontext_v2

The padding in the target_ucontext_v2 is defined by the size of the target's sigset_t type, not the host's. (This bug only causes problems when we start using the uc_regspace[] array to expose VFP registers to userspace signal handlers.) Signed-off-by: Peter Maydell --- linux-user/signal.c |

[Qemu-devel] [PATCH 3/6] ARM: linux-user: Expose VFP registers to signal handlers

For ARM linux-user mode signal handlers, fill in the ucontext with VFP register contents in the same way that the kernel does. We only do this for v2 format sigframe (2.6.12 and above); this is actually bug-for-bug compatible with the older kernels, which don't save and restore VFP registers either
