2010-03-06ppc440_bamboo: Disable new virtio-serial features for 0.12 machine typeAmit Shah
Disable the MULTIPORT feature and MSI vectors for the 0.12 machine types; those features are added only for 0.13 onwards. Signed-off-by: Amit Shah <amit.shah@redhat.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-03-06ppc440_bamboo: Add 0.12 and 0.13 machine types for backward compatAmit Shah

2010-03-06s390-virtio: Fix compile error for virtio-block initAmit Shah
Commit 428c149b0be790b440e1cbee185b152cdb22feec modified the argument that virtio_blk_init takes. Update the s390 bus code that calls this function. Signed-off-by: Amit Shah <amit.shah@redhat.com> CC: Christoph Hellwig <hch@lst.de> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-03-06hw/serial.c: fix THRE interrupt clearingAurelien Jarno
UART_IIR_THRI is not a mask, but a possible value for the IIR ID. Use UART_IIR_ID to extract this value. Broken by commit 71e605f80313a632cc6714cde7bd240042dbdd95. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2010-03-04x86: Extend validity of bsp_to_cpuJan Kiszka
As we hard-wire the BSP to CPU 0 anyway and cpuid_apic_id equals cpu_index, bsp_to_cpu can also be based on the latter directly. This will help an early user of it: KVM while initializing mp_state.

2010-03-04KVM: Rework VCPU state writeback APIJan Kiszka
This grand cleanup drops all reset and vmsave/load related synchronization points in favor of four(!) generic hooks: - cpu_synchronize_all_states in qemu_savevm_state_complete (initial sync from kernel before vmsave) - cpu_synchronize_all_post_init in qemu_loadvm_state (writeback after vmload) - cpu_synchronize_all_post_init in main after machine init - cpu_synchronize_all_post_reset in qemu_system_reset (writeback after system reset) These writeback points + the existing one of VCPU exec after cpu_synchronize_state map on three levels of writeback: - KVM_PUT_RUNTIME_STATE (during runtime, other VCPUs continue to run) - KVM_PUT_RESET_STATE (on synchronous system reset, all VCPUs stopped) - KVM_PUT_FULL_STATE (on init or vmload, all VCPUs stopped as well) This level is passed to the arch-specific VCPU state writing function that will decide which concrete substates need to be written. That way, no writer of load, save or reset functions that interact with in-kernel KVM states will ever have to worry about synchronization again. That also means that a lot of reasons for races, segfaults and deadlocks are eliminated. cpu_synchronize_state remains untouched, just as Anthony suggested. We continue to need it before reading or writing of VCPU states that are also tracked by in-kernel KVM subsystems. Consequently, this patch removes many cpu_synchronize_state calls that are now redundant, just like remaining explicit register syncs.

2010-03-04Allocate memory below 4GB as one chunkAvi Kivity

2010-03-03eepro100: Keep includes sortedStefan Weil
I always try to keep standard includes sorted and add a comment why they are there (so they can be removed when they are no longer needed). Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2010-03-03eepro100: Remove C++ commentsStefan Weil

2010-03-03eepro100: New function for reading command blockStefan Weil

2010-03-03eepro100: Use tx.statusStefan Weil

2010-03-03eepro100: Use symbolic names and BIT macros in binary operationsStefan Weil
Instead of magic numbers like 0x8000, symbolic names are used for the SCB command and status bits. There are too many configuration bits to use symbolic names there, too. Using the BIT macro is a little help when comparing code and documentation. For the same reason, some other constants were replaced by the BITS macro.

2010-03-03eepro100: Support gpxe boot for all eepro100 devicesStefan Weil
Only two boot ROM files are needed for all devices. * Add these GPXE ROM files using new naming convention (as discussed on qemu-devel). Both files were created with http://rom-o-matic.net/, PCI vendor / device ids as in ROM filenames and option BANNER_TIMEOUT = 0. * Remove old PXE ROM file for i82559er. It was replaced by gpxe-eepro100-80861209.rom. * Update pc-bios/README (and sort entries). Full support still needs additional eepro100 fixes.

2010-02-22Fix lost serial TX interrupts. Report receive overruns.Justin T. Gibbs
o Implement receive overrun status. The FreeBSD uart driver relies on this status in it's probe routine to determine the size of the FIFO supported. o As per the 16550 spec, do not overwrite the RX FIFO on an RX overrun. o Do not allow TX or RX FIFO overruns to increment the data valid count beyond the size of the FIFO. o For reads of the IIR register, only clear the "TX holding register emtpy interrupt" if the read reports this interrupt. This is required by the specification and avoids losing TX interrupts when other, higher priority interrupts (usually RX) are reported first. Signed-off-by: Justin T.

2010-02-19QEMU e820 reservation patchJes Sorensen
Hi, Kevin and I have agreed on the approach for this one now. So here is the latest version of the patch for QEMU, submitting e820 reservation entries via fw_cfg. Cheers, Jes Use qemu-cfg to provide the BIOS with an optional table of e820 entries. Notify the BIOS of the location of the TSS+EPT range to by reserving it via the e820 table. This matches a corresponding patch for Seabios, however older versions of Seabios will default to the hardcoded address range and stay compatible with current QEMU.

2010-02-19USB HID does not support Set_IdleKevin O'Connor
I found that the QEMU USB keyboard support does not work properly with the Set_Idle command. Once a non-zero value is given to Set_Idle, then the keyboard reports an event on every poll - not based on the time issued in the Set_Idle command. I changed the code (see patch below) and it works for me. I'm not that familiar with the qemu internals, so I'm not sure if this is the best way to implement this feature. -Kevin Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
