2011-03-21e1000: Fix multi-descriptor packet checksum offloadStefan Hajnoczi1-1/+3
The PCI/PCI-X Family of Gigabit Ethernet Controllers Software Developer’s Manual states the following about the POPTS field: Provides a number of options which control the handling of this packet. This field is ignored except on the first data descriptor of a packet. The current implementation always loads the field and its checksum offload flags. This patch uses only the first descriptor's POPTS field in order to comply with the specification. When Solaris sends multi-descriptor packets it fills in POPTS for the first descriptor only. Therefore this patch is necessary in order to perform checksum offload correctly for multi-descriptor packets. Reported-by: Daniel Pecka <dpecka@techniservit.cz> Reported-by: Gabriele A.

2011-03-21hw/arm_sysctl.c: Add the Versatile Express system registersPeter Maydell1-1/+63
Add support for the Versatile Express SYS_CFG registers, which provide a generic means of reading or writing configuration information from various parts of the board. We only implement shutdown and reset. Also make the RESETCTL register RAZ/WI on Versatile Express rather than reset the board. Other system registers are generally the same as Versatile and Realview. This includes a VMState version number bump for arm_sysctl, since we have new register state to preserve. It also adds sys_mci to the VMState while we're bumping the version number (an accidental omission from commit b50ff6f5).

2011-03-21char: Prevent multiple devices opening same chardevAmit Shah1-1/+6
Prevent: -chardev socket,path=/tmp/foo,server,nowait,id=c0 \ -device virtserialport,chardev=c0,id=vs0 \ -device virtserialport,chardev=c0,id=vs1 Reported-by: Mike Cao <bcao@redhat.com> Signed-off-by: Amit Shah <amit.shah@redhat.com>
2011-03-21virtio-console: Keep chardev open for other users after hot-unplugAmit Shah1-1/+5
After a hot-unplug operation, the previous behaviour was to close the chardev. That meant the chardev couldn't be re-used. Also, since chardev hot-plug isn't possible so far, this means virtio-console hot-plug isn't feasible as well. With this change, the chardev is kept around. A new virtio-console channel can then be hot-plugged with the same chardev and things will continue to work. Signed-off-by: Amit Shah <amit.shah@redhat.com>
2011-03-21virtio-serial: Don't clear ->have_data() pointer after unplugAmit Shah1-1/+0
After a port unplug operation, the port->info->have_data() pointer was set to NULL. The problem is, the ->info struct is shared by all ports, effectively disabling writes to other ports. Reported-by: juzhang <juzhang@redhat.com> Signed-off-by: Amit Shah <amit.shah@redhat.com>
2011-03-21virtio-serial-bus: Simplify handle_output() functionAmit Shah1-9/+3
There's no code change, just re-arrangement to simplify the function after recent modifications. Reported-by: Juan Quintela <quintela@redhat.com> Signed-off-by: Amit Shah <amit.shah@redhat.com>
2011-03-21virtio-serial: Enable ioeventfdAmit Shah1-0/+3
Enable ioeventfd for virtio-serial devices by default. Commit 25db9ebe15125deb32958c6df74996f745edf1f9 lists the benefits of using ioeventfd. Copying a file from guest to host over a virtio-serial channel didn't show much difference in time or io_exit rate. Signed-off-by: Amit Shah <amit.shah@redhat.com>
2011-03-21virtio-serial: Disallow generic ports at id 0Amit Shah1-0/+9
Port 0 is reserved for virtconsole devices for backward compatibility with the old -virtioconsole (from qemu 0.12) device type. libvirt prior to commit 8e28c5d40200b4c5d483bd585d237b9d870372e5 used port 0 for generic ports. libvirt will no longer do that, but disallow instantiating generic ports at id 0 from qemu as well. Signed-off-by: Amit Shah <amit.shah@redhat.com>
2011-03-21virtio-serial: Use a struct to pass config information from proxyAmit Shah4-15/+21
Instead of using a single variable to pass to the virtio_serial_init function, use a struct so that expanding the number of variables to be passed on later is easier. Signed-off-by: Amit Shah <amit.shah@redhat.com>
2011-03-21change all other clock references to use nanosecond resolution accessorsPaolo Bonzini58-246/+246
This was done with: sed -i 's/qemu_get_clock\>/qemu_get_clock_ns/' \ $(git grep -l 'qemu_get_clock\>' ) sed -i 's/qemu_new_timer\>/qemu_new_timer_ns/' \ $(git grep -l 'qemu_new_timer\>' ) after checking that get_clock and new_timer never occur twice on the same line. There were no missed occurrences; however, even if there had been, they would have been caught by the compiler. There was exactly one false positive in qemu_run_timers: - current_time = qemu_get_clock (clock); + current_time = qemu_get_clock_ns (clock); which is of course not in this patch.

2011-03-15Fix ATA SMART and CHECK POWER MODEBrian Wheeler1-13/+28
This patch fixes two things: 1) CHECK POWER MODE The error return value wasn't always zero, so it would show up as offline. Error is now explicitly set to zero. 2) SMART The smart values that were returned were invalid and tools like skdump would not recognize that the smart data was actually valid and would dump weird output. The data has been fixed up and raw value support was added. Tools like skdump and palimpsest work as expected.

2011-03-13hw/fmopl: Fix buffer access out-of-bounds errorsStefan Weil1-1/+5
Index 75 is one too large for AR_TABLE[75], DR_TABLE[75].

MultiArcadeMachineEmulator has newer versions of fmopl, but using these requires more efforts.

2011-03-12pc: fix wrong CMOS values for floppy drivesBlue Swirl1-1/+1
Before commit 63ffb564dca94f8bda01ed6d209784104630a4d2, states for floppy drives were calculated in fdc.c:fd_revalidate(). There it is also considered whether a disk is inserted or not. The commit didn't copy the logic completely to pc.c, which caused a regression. Fix by adding the same check also to pc.c.

2011-03-10pxa2xx_timer: separate irq for pxa27x handlingDmitry Eremin-Solenikov1-4/+5
First, sysbus_init_irq shan't be called on on-stack variables. Indeed, it only stores a passed pointer in qdev and the stored irq is later populated, so we get a nice write-to-stack bug. Second, irq for pxa27x should probably be handled in a more gentler way, as we should check if we have events to raise this irq.

This patch add support for a system control block. It is supposed to act as helper for the emulated program. E.g. shutting down the VM or printing test results. This model is intended for testing purposes only and doesn't fit to any real hardware. Therefore, it is not added to any board by default.
