2013-01-27pc: Set fw_cfg data based on APIC ID calculationEduardo Habkost
This changes FW_CFG_MAX_CPUS and FW_CFG_NUMA to use apic_id_for_cpu(), so the NUMA table can be based on the APIC IDs, instead of CPU index (SeaBIOS knows nothing about CPU indexes, just APIC IDs). Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Signed-off-by: Andreas Färber <afaerber@suse.de>

2013-01-19fw_cfg: Use void *, size_t instead of uint8_t *, uint32_t for blobsMarkus Armbruster
Many callers pass size_t, which gets silently truncated to uint32_t. Harmless, because all practical sizes are well below 4GiB. Clean it up anyway. Size overflow now fails assertions.

2013-01-10Make all static TypeInfos constAndreas Färber
Since 39bffca2030950ef6efe57c2fac8327a45ae1015 (qdev: register all types natively through QEMU Object Model), TypeInfo as used in the common, non-iterative pattern is no longer amended with information and should therefore be const. Fix the documented QOM examples: sed -i 's/static TypeInfo/static const TypeInfo/g' include/qom/object.h Since frequently the wrong examples are being copied by contributors of new devices, fix all types in the tree: sed -i 's/^static TypeInfo/static const TypeInfo/g' */*.c sed -i 's/^static TypeInfo/static const TypeInfo/g' */*/*.c This also avoids to piggy-back these changes onto real functional changes or other refactorings.

(L)APIC is a part of cpu [1] so move APIC initialization inside of x86_cpu object. Since cpu_model and override flags currently specify whether APIC should be created or not, APIC creation&initialization is moved into x86_cpu_apic_init() which is called from x86_cpu_realize().

2012-08-04Fixes related to processing of qemu's -numa optionChegu Vinod
The -numa option to qemu is used to create [fake] numa nodes and expose them to the guest OS instance. There are a couple of issues with the -numa option: a) Max VCPU's that can be specified for a guest while using the qemu's -numa option is 64. Due to a typecasting issue when the number of VCPUs is > 32 the VCPUs don't show up under the specified [fake] numa nodes. b) KVM currently has support for 160VCPUs per guest. The qemu's -numa option has only support for upto 64VCPUs per guest. This patch addresses these two issues. Below are examples of (a) and (b) a) >32 VCPUs are specified with the -numa option: /usr/local/bin/qemu-system-x86_64 \ -enable-kvm \ 71:01:01 \ -net tap,ifname=tap0,script=no,downscript=no \ -vnc :4 ...

2012-08-01target-i386: move cpu halted decision into x86_cpu_resetIgor Mammedov
MP initialization protocol differs between cpu families, and for P6 and onward models it is up to CPU to decide if it will be BSP using this protocol, so try to model this. However there is no point in implementing MP initialization protocol in qemu. Thus first CPU is always marked as BSP. This patch: - moves decision to designate BSP from board into cpu, making cpu self-sufficient in this regard. Later it will allow to cleanup hw/pc.c and remove cpu_reset and wrappers from there. - stores flag that CPU is BSP in IA32_APIC_BASE to model behavior described in Inted SDM vol 3a part 1 chapter 8.4.1 - uses MSR_IA32_APICBASE_BSP flag in apic_base for checking if cpu is BSP patch is based on Jan Kiszka's proposal: http://thread.gmane.org/gmane.comp.emulators.qemu/100806 Signed-off-by: Igor Mammedov <imammedo@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2012-07-17block: Geometry and translation hints are now useless, purge themMarkus Armbruster
There are two producers of these hints: drive_init() on behalf of -drive, and hd_geometry_guess(). The only consumer of the hint is hd_geometry_guess(). The callers of hd_geometry_guess() call it only when drive_init() didn't set the hints. Therefore, drive_init()'s hints are never used. Thus, hd_geometry_guess() only ever sees hints it produced itself in a prior call. Only the first call computes something, subsequent calls just repeat the first call's results. However, hd_geometry_guess() is never called more than once: the device models don't, and the block device is destroyed on unplug. Thus, dropping the repeat feature doesn't break anything now. If a block device wasn't destroyed on unplug and could be reused with a new device, then repeating old results would be wrong. Thus, dropping the repeat feature prevents future breakage. This renders the hints unused. Purge them from the block layer. Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2012-06-19Add PIIX4 properties to control PM system states.Gleb Natapov
This patch adds two things. First it allows QEMU to distinguish between regular powerdown and S4 powerdown. Later separate QMP notification will be added for S4 powerdown. Second it allows S3/S4 states to be disabled from QEMU command line. Some guests known to be broken with regards to power management, but allow to use it anyway. Using new properties management will be able to disable S3/S4 for such guests. Supported system state are passed to a firmware using new fw_cfg file. The file contains 6 byte array. Each byte represents one system state. If byte at offset X has its MSB set it means that system state X is supported and to enter it guest should use the value from lowest 3 bits.
