* qemu-kvm: fix crash on reboot with vhost-netqemu-kvm-0.12.4-gentoo-2qemu-kvm-0.12.4-gentooMichael S. Tsirkin2010-07-203-0/+139
| | | | | | | | | | | | | | | | | | | | When vhost-net is disabled on reboot, we set msix mask notifier to NULL to disable further mask/unmask notifications. Code currently tries to pass this NULL to notifier, leading to a crash. The right thing to do is to add explicit APIs to enable/disable notifications. Now when disabling notifications: - if vector is masked, we don't need to notify backend, just disable future notifications - if vector is unmasked, invoke callback to unassign backend, then disable future notifications This patch also polls notifier before closing it, to make sure we don't lose events if poll callback didn't have time to run.

* target-ppc: fix RFI by clearing some bits of MSRThomas Monjalon2010-07-202-4/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit 2ada0ed, "Return From Interrupt" is broken for PPC processors because some interrupt specifics bits of SRR1 are copied to MSR. SRR1 is a save of MSR during interrupt. During RFI, MSR must be restored from SRR1. But some bits of SRR1 are interrupt-specific and are not used for MSR saving. This is the specification (ISA 2.06) at chapter 6.4.3 (Interrupt Processing): "2. Bits 33:36 and 42:47 of SRR1 or HSRR1 are loaded with information specific to the interrupt type. 3. Bits 0:32, 37:41, and 48:63 of SRR1 or HSRR1 are loaded with a copy of the corresponding bits of the MSR." Below is a representation of MSR bits which are not saved: 0:15 16:31 32 33:36 37:41 42:47 48:63 ——— | ——— | — X X X X — — — — — X X X X X X | ———— 0000 0000 | 7 | 8 | 3 | F | 0000 History: In the initial Qemu implementation (e1833e1), the mask 0x783F0000 was used for saving MSR in SRR1. But all the bits 32:47 were cleared during RFI restoring. This was wrong. The commit 2ada0ed explains that this breaks Altivec. Indeed, bit 38 (for Altivec support) must be saved and restored. The change of 2ada0ed was to restore all the bits of SRR1 to MSR. But it's also wrong. Explanation: As an example, let's see what's happening after a TLB miss. According to the e300 manual (E300CORERM table 5-6), the TLB miss interrupts set the bits 44-47 for KEY, I/D, WAY and S/L. These bits are specifics to the interrupt and must not be copied into MSR at the end of the interrupt. With the current implementation, a TLB miss overwrite bits POW, TGPR and ILE. Fix: It shouldn't be needed to filter-out bits on MSR saving when interrupt occurs. Specific bits overwrite MSR ones in SRR1. But at the end of interrupt (RFI), specifics bits must be cleared before restoring MSR from SRR1. The mask 0x783F0000 apply here. Discussion: The bits of the mask 0x783F0000 are cleared after an interrupt. I cannot find a specification which talks about this but I assume it is the truth since Linux can run this way. Maybe it's not perfect but it's better (works for e300).

* arm_timer: fix oneshot modeRabin Vincent2010-07-201-1/+1

* arm_timer: reload timer when enabledRabin Vincent2010-07-201-1/+1
| | | | | | | | | | | | | | | | | Reload the timer when TimerControl is written, if the timer is to be enabled. Otherwise, if an earlier write to TimerLoad was done while periodic mode was not set, s->delta may incorrectly still have the value of the maximum limit instead of the value written to TimerLoad. This problem is evident on versatileap on current linux-next, which enables TIMER_CTRL_32BIT before writing to TimerLoad and then enabling periodic mode and starting the timer. This causes the first periodic tick to be scheduled to occur after 0xffffffff periods, leading to a perceived hang while the kernel waits for the first timer tick.

* block: Handle multiwrite errors only when all requests have completedKevin Wolf2010-07-201-4/+1
| | | | | | | | | | | | | | | | | Don't try to be clever by freeing all temporary data and calling all callbacks when the return value (an error) is certain. Doing so has at least two important problems: * The temporary data that is freed (qiov, possibly zero buffer) is still used by the requests that have not yet completed. * Calling the callbacks for all requests in the multiwrite means for the caller that it may free buffers etc. which are still in use. Just remember the error value and do the cleanup when all requests have completed. Signed-off-by: Kevin Wolf <kwolf@redhat.com> (cherry picked from commit de189a1b4a471d37a2909e97646654fc9751b52f)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The fix is based on a patch from Kevin Wolf. Here his comment: "The number of blocks needs to be rounded up to cover all of the virtual hard disk. Without this fix, we can't even open our own images if their size is not a multiple of the block size." While Kevin's patch addressed vdi_create, my modification also fixes vdi_open which now accepts images with odd disk sizes. v3: Don't allow reading of disk images with too large disk sizes. Neither VBoxManage nor old versions of qemu-img read such images. This change requires rounding of odd disk sizes before we do the checks.

* block/vpc: Fix conversion from size to disk geometryStefan Weil2010-07-201-9/+12
| | | | | | | | | | | | | | | | | | | | The VHD algorithm calculates a disk geometry which is usually smaller than the requested size. QEMU tried to round up but failed for certain sizes: qemu-img create -f vpc disk.vpc 9437184 would create an image with 9435136 bytes (which is too small for qemu-img convert). Instead of hacking the geometry algorithm, the patch increases the number of sectors until we get enough sectors.

| | | | | | | | | | | After it is done with updating refcounts in the cache, update_refcount writes all changed entries to disk.

* Fix multiboot compilationAlexander Graf2010-07-202-12/+28
| | | | | | | | | | | | | | | | | | | | | | | Commit dd4239d6574ca41c94fc0d0f77ddc728510ffc57 broke multiboot. It replaced the instruction "rep insb (%dx), %es:(%edi)" by the binary output of "addr32 rep insb (%dx), %es:(%di)". Linuxboot calls the respective helper function in a code16 section. So the original instruction was automatically translated to its "addr32" equivalent. For multiboot, we're running in code32 so gcc didn't add the "addr32" which breaks the instruction. This patch splits that helper function in one which uses addr32 and one which does not, so everyone's happy. The good news is that nobody probably cared so far. The bundled multiboot.bin binary was built before the change and is thus correct. Please also put this patch into -stable.

| | | | | | | | | | | | | | | | Code for saving irq_state got vm_state macros wrong, passing in the wrong parameter. As a result, we both saved a wrong value and restored it to a wrong offset. This leads to device and bus irq counts getting out of sync, which in turn leads to interrupts getting lost or never cleared, such as https://bugzilla.redhat.com/show_bug.cgi?id=588133 Signed-off-by: Michael S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Turns out on those versions of FreeBSD (>= 7.x) that know OSS_GETVERSION the ioctl doesn't actually work yet (except in the Linuxolator), so if building on FreeBSD assume the sound drivers are new enough if the ioctl returns the errno it does currently on FreeBSD. (Rev 2 after private discussion with malc.)
