2014-08-17nic: do not destroy memory regions in cleanup functionsPaolo Bonzini2-6/+0
The memory regions should be destroyed in the unrealize function; since these NICs are not even qdev-ified, they cannot be unplugged and they do not have to do anything to destroy their memory regions.

2014-07-15spapr: Enable use of huge pagesAlexey Kardashevskiy1-8/+3
0b183fc87 "memory: move mem_path handling to memory_region_allocate_system_memory" disabled -mempath use for all machines that do not use memory_region_allocate_system_memory() to register RAM. Since SPAPR uses memory_region_init_ram(), the huge pages support was disabled for it. This replaces memory_region_init_ram()+vmstate_register_ram_global() with memory_region_allocate_system_memory() to get huge pages back. This changes RAM size from (ram_limit - rma_alloc_size) to ram_limit as the previous patch moved RMA memory region allocation after RAM allocation and therefore this change does not have immediate effect but simplifies the code.

2014-07-15spapr: Move RMA memory region registration codeAlexey Kardashevskiy1-1/+11
PPC970 does not support VRMA (virtual RMA) so real memory required for SLOF to execute must be allocated by the KVM_ALLOCATE_RMA ioctl. Later this memory is used as a part of the guest RAM area. The RMA allocating code also registers a memory region for this piece of RAM. We are going to simplify memory regions layout: RMA memory region will be a subregion in the RAM memory region, both starting from zero. This way we will not have to take care of start address alignment for the piece of RAM next to the RMA. This moves memory region business closer to the RAM memory region creation/allocation code. As this is a mechanical patch, no change in behaviour is expected.

2014-07-14serial: change retry logic to avoid concurrencyKirill Batuzov1-26/+33
Whenever serial_xmit fails to transmit a byte it adds a watch that would call it again when the "line" becomes ready. This results in a retry chain: serial_xmit -> add_watch -> serial_xmit Each chain is able to transmit one character, and for every character passed to serial by the guest driver a new chain is spawned. The problem lays with the fact that a new chain is spawned even when there is one already waiting on the watch. So there can be several retry chains waiting concurrently on one "line". Every chain tries to transmit current character, so character order is not messed up. But also every chain increases retry counter (tsr_retry). If there are enough concurrent chains this counter will hit MAX_XMIT_RETRY value and the character will be dropped. To reproduce this bug you need to feed serial output to some program consuming it slowly enough. A python script from bug #1335444 description is an example of such program. This commit changes retry logic in the following way to avoid concurrency: instead of spawning a new chain for each character being transmitted spawn only one and make it transmit characters until FIFO is empty. The change consists of two parts: - add a do {} while () loop in serial_xmit (diff is a bit erratic for this part, diff -w will show actual change), - do not call serial_xmit from serial_ioport_write if there is one waiting on the watch already. This should fix another issue causing bug #1335444. Signed-off-by: Kirill Batuzov <batuzovk@ispras.ru> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2014-07-14ide: Treat read/write beyond end as invalidMarkus Armbruster1-0/+28
The block layer fails such reads and writes just fine. However, they then get treated like valid operations that fail: the error action gets executed. Unwanted; reporting the error to the guest is the only sensible action. Reject them before passing them to the block layer. This bypasses the error action and I/O accounting. Not quite correct for DMA, because DMA can fail after some success, and when that happens, the part that succeeded isn't counted. Tolerable, because I/O accounting is an inconsistent mess anyway.

2014-07-14virtio-blk: Bypass error action and I/O accounting on invalid r/wMarkus Armbruster1-6/+8
When a device model's I/O operation fails, we execute the error action. This lets layers above QEMU implement thin provisioning, or attempt to correct errors before they reach the guest. But when the I/O operation fails because it's invalid, reporting the error to the guest is the only sensible action. If the guest's read or write asks for an invalid sector range, fail the request right away, without considering the error action. No change with error action BDRV_ACTION_REPORT. Furthermore, bypass I/O accounting, because we want to track only I/O that actually reaches the block layer. The next commit will extend "invalid sector range" to cover attempts to read/write beyond the end of the medium.

The memory allocation between hw/block/virtio-blk.c, hw/block/dataplane/virtio-blk.c, and hw/virtio/dataplane/vring.c is messy. Structs are allocated in different files than they are freed in.

Use qemu_system_vmstop_request_prepare()/qemu_system_vmstop_request() instead; yet another alternative could be a BH. I checked other occurrences of vm_stop and they should not have this problem.

2014-07-08s390x/css: reflect cpa in scswCornelia Huck1-0/+9
We neglected to update the the channel-program-address field of the scsw after completion of the start or the halt function: Fortunately, Linux didn't miss it so far. Let's update it for the cases where the cpa is expected to be valid; in some cases, the cpa is 'unpredictable', so we leave it untouched.

2014-07-08hw/arm/vexpress: Alias NOR flash at 0 for vexpress-a9Peter Maydell1-1/+1
Make the vexpress-a9 board alias the first NOR flash region at address zero, like vexpress-a15. This makes "-bios" actually usable on this board.

2014-07-08target-ppc: KVMPPC_H_CAS fix cpu-version endianessLaurent Dufour1-2/+1
During KVMPPC_H_CAS processing, the cpu-version updated value is stored without taking care of the current endianess. As a consequence, the guest may not switch to the right CPU model, leading to unexpected results. If needed, the value is now converted.

pc,vhost,virtio fixes, test Bugfixes all over the place. There's a non bugfix here: re-enabling the vhost-user test, though the patch just brings back functionality that I disabled earlier to fix mingw build failures. This is now sorted, and keeping the unit test enabled seems important since the feature relies on an external server to work, so isn't easy to test. Signed-off-by: Michael S.
