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. This allows us to reuse the feature XML files. * Patch 4 whitespace fixes # gpg: Signature made Mon 01 Sep 2014 12:53:39 BST using RSA key ID B5A61C7C # gpg: Can't check signature: public key not found * remotes/borntraeger/tags/kvm-s390-20140901: s390x/gdb: coding style fixes s390x/gdb: generate target.xml and handle fp/ac as coprocessors s390x/gdb: add the feature xml files for s390x s390x/gdb: don't touch the cc if tcg is not enabled sclp-s390: Add memory hotplug SCLPs s390-virtio: Apply same memory boundaries as virtio-ccw virtio-ccw: Include standby memory when calculating storage increment sclp-s390: Add device to manage s390 memory hotplug pc-bios/s390-ccw.img binary update pc-bios/s390-ccw: Do proper console setup pc-bios/s390-ccw: IPL from DASD with format variations pc-bios/s390-ccw Really big EAV ECKD DASD handling pc-bios/s390-ccw Improve ECKD informational message pc-bios/s390-ccw: handle more ECKD DASD block sizes pc-bios/s390-ccw: support all virtio block size s390x/kvm: execute the first cpu reset on the vcpu thread s390x/kvm: execute "system reset" cpu resets on the vcpu thread s390x/kvm: execute sigp orders on the target vcpu thread s390x/kvm: run guest triggered resets on the target vcpu thread Signed-off-by: Peter Maydell <peter.maydell@linaro.org>

2014-09-01s390x/gdb: generate target.xml and handle fp/ac as coprocessorsDavid Hildenbrand
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.

2014-09-01pc-bios/s390-ccw: handle more ECKD DASD block sizesEugene (jno) Dvurechenski
Using dasdfmt(8) to format a DASD allows to choose a block size. There are four supported values: 512, 1024, 2048, and 4096 bytes per block. Each block size leads to selection of new count of sectors per track. The head count remains always the same: 15. This empiric knowledge is used to detect ECKD DASD to IPL from.

The block size value may be given "as is" OR as a base value and a shift count (exponent). So, we have to use calculation to get the proper number in the code. The main expression reads as (blk_cfg.blk_size << blk_cfg.physical_block_exp) E.g., various combinations between blk_size=1/physical_block_exp=12 and blk_size=4096/physical_block_exp=0 are valid for 4K blocks.

2014-08-29curl: Don't deref NULL pointer in call to aio_poll.Richard W.M. Jones
In commit 63f0f45f2e89b60ff8245fec81328ddfde42a303 the following mechanical change was made: if (!state) { - qemu_aio_wait(); + aio_poll(state->s->aio_context, true); } The new code now checks if state is NULL and then dereferences it ('state->s') which is obviously incorrect. This commit replaces state->s->aio_context with bdrv_get_aio_context(bs), fixing this problem. The two other hunks are concerned with getting the BlockDriverState pointer bs to where it is needed. The original bug causes a segfault when using libguestfs to access a VMware vCenter Server and doing any kind of complex read-heavy operations. With this commit the segfault goes away.

2014-08-29curl: Allow a cookie or cookies to be sent with http/https requests.Richard W.M. Jones
In order to access VMware ESX efficiently, we need to send a session cookie. This patch is very simple and just allows you to send that session cookie. It punts on the question of how you get the session cookie in the first place, but in practice you can just run a `curl' command against the server and extract the cookie that way. To use it, add file.cookie to the curl URL. For example: $ qemu-img info 'json: { "file.driver":"https", "file.url":"https://vcenter/folder/Windows%202003/Windows%202003-flat.vmdk?dcPath=Datacenter&dsName=datastore1", "file.sslverify":"off", "file.cookie":"vmware_soap_session=\"52a01262-bf93-ccce-d379-8dabb3e55560\""}' image: [...] file format: raw virtual size: 8.0G (8589934592 bytes) disk size: unavailable Signed-off-by: Richard W.M.

Make drive_del safe for dataplane where another thread may be running the BlockDriverState's AioContext. Note the assumption that AioContext's lifetime exceeds DriveInfo and BlockDriverState. We release AioContext after DriveInfo and BlockDriverState are potentially freed. This is clearly safe with the global AioContext but also with -object iothread and implicit iothreads created by -device virtio-blk-pci,x-data-plane=on (their lifetime is tied to DeviceState, not BlockDriverState).

2014-08-29linux-aio: avoid deadlock in nested aio_poll() callsStefan Hajnoczi
If two Linux AIO request completions are fetched in the same io_getevents() call, QEMU will deadlock if request A's callback waits for request B to complete using an aio_poll() loop. This was reported to happen with the mirror blockjob. This patch moves completion processing into a BH and makes it resumable. Nested event loops can resume completion processing so that request B will complete and the deadlock will not occur.

2014-08-29arm: Implement PMCCNTR 32b read-modify-writePeter Crosthwaite
The register is now 64bit, however a 32 bit write to the register should leave the higher bits unchanged. The open coded write handler does not implement this, so we need to read-modify-write accordingly.

2014-08-29aarch64: raise max_cpus to 8Joel Schopp
I'm running on a system with 8 cpus and it would be nice to have qemu support all of them. The attached patch does that and has been tested. That said, I'm not sure if 8 is enough or if we want to bump this even higher now before systems with many more cpus come along. 255 anyone?

2014-08-29target-arm: Correct Cortex-A57 ISAR5 and AA64ISAR0 ID register valuesPeter Maydell
We implement the crypto extensions but were incorrectly reporting ID register values for the Cortex-A57 which did not advertise crypto. Use the correct values as described in the TRM. With this fix Linux correctly detects presence of the crypto features and advertises them in /proc/cpuinfo.

2014-08-29target-arm: Fix regression that disabled VFP for ARMv5 CPUsPeter Maydell
Commit 2c7ffc414 added support for honouring the CPACR coprocessor access control register bits which may disable access to VFP and Neon instructions. However it failed to account for the fact that the CPACR is only present starting from the ARMv6 architecture version, so it accidentally disabled VFP completely for ARMv5 CPUs like the ARM926. Linux would detect this as "no VFP present" and probably fall back to its own emulation, but other guest OSes might crash or misbehave. This fixes bug LP:1359930.

2014-08-29block: fix overlapping multiwrite requestsStefan Hajnoczi
When request A is a strict superset of request B: AAAAAAAA BBBB multiwrite_merge() merges them as follows: AABBBB The tail of request A should have been included: AABBBBAA This patch fixes data loss but this code path is probably rare. Since guests cannot assume ordering between in-flight requests, few applications submit overlapping write requests.
