2014-09-04vbe: make bochs dispi interface return the correct memory size with qxlGerd Hoffmann3-2/+7
VgaState->vram_size is the size of the pci bar. In case of qxl not the whole pci bar can be used as vga framebuffer. Add a new variable vbe_size to handle that case. By default (if unset) it equals vram_size, but qxl can set vbe_size to something else. This makes sure VBE_DISPI_INDEX_VIDEO_MEMORY_64K returns correct results and sanity checks are done with the correct size too.

2014-09-03acpi-build: Set FORCE_APIC_CLUSTER_MODEL bit for FADT flagszhanghailiang1-0/+6
If we start Windows 2008 R2 DataCenter with number of cpu less than 8, The system will use APIC Flat Logical destination mode as default configuration, Which has an upper limit of 8 CPUs. The fault is that VM can not show all processors within Task Manager if we hot-add cpus when the number of cpus in VM extends the limit of 8. If we use cluster destination model, the problem will be solved. Note: This flag was introduced later than ACPI v1.0 specification while QEMU generates v1.0 tables only, but... linux kernel ignores this flag, so patch has no influence on it. Tested with Win[XPsp3|Srv2003EE|Srv2008DC|Srv2008R2|Srv2012R2], there isn't BSODs and guests boot just fine. In cases guest doesn't support cpu-hotplug, cpu becomes visible after reboot and in case the guest supports cpu-hotplug, it works as expected with this patch.

2014-09-03vhost-scsi: init backend features earlierMichael S. Tsirkin1-1/+1
As vhost core can use backend_features during init, clear it earlier to avoid using uninitialized memory. This use would be harmless since vhost scsi ignores the result anyway, but initializing earlier will help prevent valgrind errors, and make scsi and net behave similarly.

As this field is now uninitialized, vhost initialization will sometimes fail. To fix, initialize acked_features on each ack.

2014-09-03vhost_net: start/stop guest notifiers properlyJason Wang2-16/+27
commit a9f98bb5ebe6fb1869321dcc58e72041ae626ad8 "vhost: multiqueue support" changed the order of stopping the device. Previously vhost_dev_stop would disable backend and only afterwards, unset guest notifiers. We now unset guest notifiers while vhost is still active. This can lose interrupts causing guest networking to fail. In particular, this has been observed during migration. To fix this, several other changes are needed: - remove the hdev->started assertion in vhost.c since we may want to start the guest notifiers before vhost starts and stop the guest notifiers after vhost is stopped. - introduce the vhost_net_set_vq_index() and call it before setting guest notifiers. This is to guarantee vhost_net has the correct virtqueue index when setting guest notifiers. MST: fix up error handling.

With security_model=mapped-xattr, we encode the uid,gid and other file attributes as extended attributes of the file. We save them under user.virtfs.* namespace. Use little-endian encoding for on-disk values. This enables us to export the same directory from both little-endian and big-endian hosts. NOTE: This will break big-endian host that have virtFS exports using security model mapped-xattr. They will have to use external tools to convert the xattr to little-endian format.

2014-09-01implementing victim TLB for QEMU system emulated TLBXin Tong3-7/+76
QEMU system mode page table walks are expensive. Taken by running QEMU qemu-system-x86_64 system mode on Intel PIN , a TLB miss and walking a 4-level page tables in guest Linux OS takes ~450 X86 instructions on average. QEMU system mode TLB is implemented using a directly-mapped hashtable. This structure suffers from conflict misses. Increasing the associativity of the TLB may not be the solution to conflict misses as all the ways may have to be walked in serial. A victim TLB is a TLB used to hold translations evicted from the primary TLB upon replacement. The victim TLB lies between the main TLB and its refill path. Victim TLB is of greater associativity (fully associative in this patch). It takes longer to lookup the victim TLB, but its likely better than a full page table walk. The memory translation path is changed as follows : Before Victim TLB: 1. Inline TLB lookup 2. Exit code cache on TLB miss. 3. Check for unaligned, IO accesses 4. TLB refill. 5. Do the memory access. 6. Return to code cache. After Victim TLB: 1. Inline TLB lookup 2. Exit code cache on TLB miss. 3. Check for unaligned, IO accesses 4. Victim TLB lookup. 5. If victim TLB misses, TLB refill 6. Do the memory access. 7. Return to code cache The advantage is that victim TLB can offer more associativity to a directly mapped TLB and thus potentially fewer page table walks while still keeping the time taken to flush within reasonable limits. However, placing a victim TLB before the refill path increase TLB refill path as the victim TLB is consulted before the TLB refill. The performance results demonstrate that the pros outweigh the cons. some performance results taken on SPECINT2006 train datasets and kernel boot and qemu configure script on an Intel(R) Xeon(R) CPU E5620 @ 2.40GHz Linux machine are shown in the Google Doc link below. https://docs.google.com/spreadsheets/d/1eiItzekZwNQOal_h-5iJmC4tMDi051m9qidi5_nwvH4/edit?usp=sharing In summary, victim TLB improves the performance of qemu-system-x86_64 by 11% on average on SPECINT2006, kernelboot and qemu configscript and with highest improvement of in 26% in 456.hmmer. And victim TLB does not result in any performance degradation in any of the measured benchmarks. Furthermore, the implemented victim TLB is architecture independent and is expected to benefit other architectures in QEMU as well. Although there are measurement fluctuations, the performance improvement is very significant and by no means in the range of noises.

into staging s390x/kvm: Several updates/fixes/features 1. s390x/kvm: avoid synchronize_rcu's in kernel ---------------------------------------------- The first patches change s390x/kvm code to issue VCPU specific ioctls from the VCPU thread. This will avoid unnecessary synchronize_rcu in the kernel, which caused a noticably slowdown with many guest CPUs. It speeds up all start/restart/reset operations involving cpus drastically. 2. s390-ccw.img: block size and DASD format support --------------------------------------------------- The second part changes the s390-ccw bios to IPL (boot) more disk formats than before. Furthermore a small fix is made to the console output of the bios. 3. s390: Support for Hotplug of Standby Memory ---------------------------------------------- The third part adds support in s390 for a pool of standby memory, which can be set online/offline by the guest (ie, via chmem). The standby pool of memory is allocated as the difference between the initial memory setting and the maxmem setting. As part of this work, additional results are provided for the Read SCP Information SCLP, and new implentation is added for the Read Storage Element Information, Attach Storage Element, Assign Storage and Unassign Storage SCLPs, which enables the s390 guest to manipulate the standby memory pool. This patchset is based on work originally done by Jeng-Fang (Nick) Wang. Sample qemu command snippet: qemu -machine s390-ccw-virtio -m 1024M,maxmem=2048M,slots=32 -enable-kvm This will allocate 1024M of active memory, and another 1024M of standby memory. Example output from s390-tools lsmem: ============================================================================= 0x0000000000000000-0x000000000fffffff 256 online no 0-127 0x0000000010000000-0x000000001fffffff 256 online yes 128-255 0x0000000020000000-0x000000003fffffff 512 online no 256-511 0x0000000040000000-0x000000007fffffff 1024 offline - 512-1023 Memory device size : 2 MB Memory block size : 256 MB Total online memory : 1024 MB Total offline memory: 1024 MB The guest can dynamically enable part or all of the standby pool via the s390-tools chmem, for example: chmem -e 512M And can attempt to dynamically disable: chmem -d 512M 4. s390x/gdb: various fixes --------------------------- * Patch 1 fixes a bug where the cc was changed accidentally. * Patch 2 adds the gdb feature XML files for s390x * Patch 3 Define acr and fpr registers as coprocessor registers.

Damn, the dirty rectangle values are signed integers. So the checks added by commit 788fbf042fc6d5aaeab56757e6dad622ac5f0c21 are not good enough, we also have to make sure they are not negative. [ Note: There must be something broken in spice-server so we get negative values in the first place.

2014-09-01s390x/gdb: generate target.xml and handle fp/ac as coprocessorsDavid Hildenbrand4-60/+76
This patch reduces the core registers to the psw and the general purpose registers. The fpc and ac registers are handled as coprocessors registers by gdb. This allows to reuse the feature xml files taken from gdb without further modification and is what other architectures do. The target.xml is now generated and provided to the gdb client. Therefore, the client doesn't have to guess which registers are available at which logical register number.
