2009-05-12Push AUD_init down to devicesPaul Brook
Now we can safely call AUD_init multiple times we can push it down to individual audio devices, rather than having to pass it from the board init. Signed-off-by: Paul Brook <paul@codesourcery.com>
2009-05-12Make AUD_init failure fatalPaul Brook
Failure to initialize the audio subsystem is not handled consistently. Where it is handled it has guest visible effects, which is wrong. We already have a "nosound" audio driver as a last resort, so trying to proceed without an audio backend seems pointless. Also protect against multiple calls to AUD_init so that this can be pushed down into individual devices. Signed-off-by: Paul Brook <paul@codesourcery.com>

2009-05-08vga: Replace VGA_COMMON with a structureAvi Kivity
All VGA devices share a common field subset; currently they do so by a macro which defines the common fields inline their state structures, relying on the the common state being placed at offset 0 in the structure. This makes refactoring the code difficult and requires a lot of error prone casts. Replace the macro by a new VGACommonState structure, and the casts by regular field access and container_of() for upcasts.

2009-05-08e1000: Do not reinit pci config space to 0Amit Shah
pci_register_device already mallocs the pci config space buffer filled with zeroes. Doing this again breaks some default config space writes like setting the subsystem vendor id and subsystem device id.

2009-05-08reset state for load_linuxGlauber Costa
The linux loader is just an option rom like any other, just with some special requirements. Right now, our option rom resetting mechanism is not being applied to it. As a result, users using -kernel will not be able to successfully reboot their machines This patch fixes it by saving all the data we generated in the load_linux() function, to be used later by the option rom resetting mechanism.

2009-05-08register reset handler for option_romsGlauber Costa
Currently, boot options are not preserved across a system reset. option roms can modify themselves, or can for instance restore the real int 0x19 vector after they tried to boot from it. To properly do that, we need a reset handler registered to deal with option roms. This patch is based on current version on qemu-kvm.git Signed-off-by: Glauber Costa <glommer@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-05-01suport device driver initialization modelGlauber Costa
According to PnP specification, Appendix B, Option ROMs that support DDIM (device driver initialization model) should have their memory space writeable. KVM deviates from us here, by removing the IO_MEM_ROM flag, to allow for PCI option ROMs (they require DDIM). However, there's absolutely no reason we can't do the same.

2009-05-01virtio-blk: add SGI_IO passthru supportChristoph Hellwig
[had the qemu list address wrong the first time, reply to this message, not the previous if you were on Cc] Add support for SG_IO passthru (packet commands) to the virtio-blk backend. Conceptually based on an older patch from Hannes Reinecke but largely rewritten to match the code structure and layering in virtio-blk. Note that currently we issue the hose SG_IO synchronously. We could easily switch to async I/O, but that would required either bloating the VirtIOBlockReq by the size of struct sg_io_hdr or an additional memory allocation for each SG_IO request.

2009-04-22Change RTC time drift IRQ re-injection (Gleb Natapov)aliguori
Currently IRQ are reinjected as soon as they are acknowledged to the RTC, but Windows sometimes do acknowledgement in a loop with global interrupt disabled waiting for interrupt to be cleared and it does not mask RTC vector in PIC/APIC while doing this. In such situation interrupt injection always fails and RTC interrupt is never cleared. Instead of reinjecting coalesced IRQs on acknowledgement the patch below reinjects them by accelerating RTC clock a bit. This way RTC interrupt is not constantly raced after coalesced interrupt.

2009-04-22implement qemu_blockalign (Stefano Stabellini)aliguori
this patch adds a buffer_alignment field to BlockDriverState and implements a qemu_blockalign function that uses that field to allocate a memory aligned buffer to be used by the block driver. buffer_alignment is initialized to 512 but each block driver can set a different value (at the moment none of them do). This patch modifies ide.c, block-qcow.c, block-qcow2.c and block.c to use qemu_blockalign instead of qemu_memalign. There is only one place left that still uses qemu_memalign to allocate buffers used by block drivers that is posix-aio-compat:handle_aiocb_rw because it is not possible to get the BlockDriverState from that function. However I think it is not important because posix-aio-compat already deals with driver specific code so it is supposed to know its own needs.

2009-04-22xen: add net backend driver. (Gerd Hoffmann)aliguori
This patch adds a network interface backend driver to qemu. It is a pure userspace implemention using the gntdev interface. It uses "qnet" as backend name in xenstore so it doesn't interfere with the netback backend (aka "vnif"). The network backend is hooked into the corrosponding qemu vlan, i.e. vif 0 is hooked into vlan 0. To make the packages actually arrive somewhere you additionally have to link the vlan to the outside world using the usual qemu command line options such as "-net tap,...".

2009-04-19Adds SM501 usb host emulation feature.aurel32
It makes usb keyboard available for sh4/r2d system emulation. The changes for "hw/usb-ohci.c" are as follows. - 'localmem_base' is introduced as OHCIState struct member. SM501 has a local memory, and it is used to pass and receive data with OHCI driver. OHCI driver accesses it with SH4 physical memory address, and SM501 accesses it with SM501 local address. 'localmem_base' holds where the SM501 local memory is mapped into SH4 physical address space. - Memory access functions modified to adjust address with 'localmem_base'. The functions are, ohci_read_*(), ohci_put_*(), and ohci_copy_*(). - ohci_read_hcca() and ohci_put_hcca() are introduced for more consistent implementation. For other source files, it does, - introduces usb_ohci_init_sm501(). - adds irq argument for SM501 initialization, to emulate USB interrupts.
