2012-09-19pflash_cfi01: fix vendor specific extended queryAurelien Jarno1-1/+3
pflash_cfi01 announces a version number of 1.1, which implies "Protection Register Information" and "Burst Read information" sections, which are not provided. Decrease the version number to 1.0 so that only the "Protection Register Information" section is needed. Set the number of protection fields (0x3f) to 0x01, as 0x00 means 256 protections field, which makes the CFI table bigger than the current implementation, causing some kernels to fail to read it.

2012-09-14net: fix usbnet_receive() packet dropsStefan Hajnoczi1-3/+16
The USB network interface has a single buffer which the guest reads from. This patch prevents multiple calls to usbnet_receive() from clobbering the input buffer. Instead we queue packets until buffer space becomes available again. This is inspired by virtio-net and e1000 rxbuf handling. Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com>

2012-09-14eepro100: Fix network hang when rx buffers run outBo Yang1-1/+3
This is reported by QA. When installing os with pxe, after the initial kernel and initrd are loaded, the procedure tries to copy files from install server to local harddisk, the network becomes stall because of running out of receive descriptor. [Whitespace fixes and removed qemu_notify_event() because Paolo's earlier net patches have moved it into qemu_flush_queued_packets(). Additional info: I can reproduce the network hang with a tap device doing a iPXE HTTP boot as follows: $ qemu -enable-kvm -m 1024 \ -netdev tap,id=netdev0,script=no,downscript=no \ -device i82559er,netdev=netdev0,romfile=80861209.rom \ -drive if=virtio,cache=none,file=test.img iPXE> ifopen net0 iPXE> config # set static network configuration iPXE> kernel http://mirror.bytemark.co.uk/fedora/linux/releases/17/Fedora/x86_64/os/images/pxeboot/vmlinuz I needed a vanilla iPXE ROM to get to the iPXE prompt. I think the boot prompt has been disabled in the ROMs that ship with QEMU to reduce boot time. During the vmlinuz HTTP download there is a network hang. hw/eepro100.c has reached the end of the rx descriptor list. When the iPXE driver replenishes the rx descriptor list we don't kick the QEMU net subsystem and event loop, thereby leaving the tap netdev without its file descriptor in select(2).

2012-09-14xen: flush queue when getting an eventPaolo Bonzini1-0/+1
xen does not have a register that, when written, will cause can_receive to go from false to true. However, flushing the queue can be attempted whenever the front-end raises its side of the Xen event channel. There is a single event channel for tx and rx.

2012-09-14e1000: flush queue whenever can_receive can go from false to truePaolo Bonzini1-0/+4
When the guests replenish the receive ring buffer, the network device should flush its queue of pending packets. This is done with qemu_flush_queued_packets. e1000's can_receive can go from false to true when RCTL or RDT are modified.

2012-09-14net: notify iothread after flushing queuePaolo Bonzini1-4/+0
virtio-net has code to flush the queue and notify the iothread whenever new receive buffers are added by the guest. That is fine, and indeed we need to do the same in all other drivers. However, notifying the iothread should be work for the network subsystem. And since we are at it we can add a little smartness: if some of the queued packets already could not be delivered, there is no need to notify the iothread.

2012-09-13hw/qxl: support client monitor configuration via deviceAlon Levy1-0/+79
Until now we used only the agent to change the monitor count and each monitor resolution. This patch introduces the qemu part of using the device as the mediator instead of the agent via virtio-serial. Spice (>=0.11.5) calls the new QXLInterface::client_monitors_config, which returns wether the interrupt is enabled, and if so and given a non NULL monitors config will generate an interrupt QXL_INTERRUPT_CLIENT_MONITORS_CONFIG with crc checksum for the guest to verify a second call hasn't interfered. The maximal number of monitors is limited on the QXLRom to 64. Signed-off-by: Alon Levy <alevy@redhat.com> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2012-09-12ahci: properly reset PxCMD on HBA resetJason Baron1-1/+1
While testing q35, I found that windows 7 (specifically, windows 7 ultimate with sp1 x64), wouldn't install because it can't find the cdrom or disk drive. The failure message is: 'A required cd/dvd device driver is missing. If you have a driver floppy disk, CD, DVD, or USB flash drive, please insert it now.' This can also be reproduced on piix by adding an ahci controller, and observing that windows 7 does not see any devices behind it. The problem is that when windows issues a HBA reset, qemu does not reset the individual ports' PxCMD register. Windows 7 then reads back the PxCMD register and presumably assumes that the ahci controller has already been initialized. Windows then never sets up the PxIE register to enable interrupts, and thus it never gets irqs back when it sends ata device inquiry commands. This change brings qemu into ahci 1.3 specification compliance. Section 10.4.3 HBA Reset: " When GHC.HR is set to '1', GHC.AE, GHC.IE, the IS register, and all port register fields (except PxFB/PxFBU/PxCLB/PxCLBU) that are not HwInit in the HBA's register memory space are reset. " I've also re-tested Fedora 16 and 17 to verify that they continue to work with this change.

2012-09-12qxl: Ignore set_client_capabilities pre/post migrateHans de Goede1-0/+5
The recent introduction of set_client_capabilities has broken (seamless) migration by trying to call qxl_send_events pre (seamless incoming) and post (*) migration, triggering the following assert: qxl_send_events: Assertion `qemu_spice_display_is_running(&d->ssd)' failed. The solution is easy, pre migration the guest will have already received the client caps on the migration source side, and post migration there no longer is a guest, so we can simply ignore the set_client_capabilities call in both those scenarios. *) Post migration, so not fatal for to the migration itself, but still a crash Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
