  • SH4: Switch serial emulation to qemu_irq ...
    4e7ed2d1 
    This patches makes SH serial emulation use qemu_irq in its interface.

        * hw/sh.h (sh_serial_init): Take qemu_irq, not intc_source.
        * hw/sh7750.c (sh7750_init): Adjust.
        * hw/sh_intc.c (sh_intc_set_irq): Don't assert or deassert
        irq more than once.
        * hw/sh_serial.c (sh_serial_state): Use qemu_irq, not intc_source.
        (sh_serial_clear_fifo, sh_serial_ioport_write)
        (sh_serial_receive_byte): Adjust.
        (sh_serial_init): Take qemu_irq, not intc_source.

  • e1000 VLAN offload emulation (Alex Williamson) ...
    8f2e8d1f 
    We're currently ignoring the e1000 VLAN tagging, stripping and filtering
features in the e1000 emulation.  This patch adds backing for the
relevant registers and provides a software implementation of the
acceleration, such that a guest can make use of VLANs.

This is mostly (only?) useful for a guest on a bridge (not user mode
networking).  The only caveat beyond that is that you need to make sure
the host NIC isn't doing it's own tagging, stripping, or filtering.
This generally means the host NIC on the bridge should not be part of a
VLAN.

  • Fix media detection on emulated CDROM (Gary Grebus) ...
    d5b4eb40 
    This patch tweaks the ATAPI CDROM emulation to fix an annoyance seen
when running a variety of Linux guests: the desktop GUI shows a CDROM
device as present, but is unable to automount the media and display its
contents.

The patch adds the PLAY_AUDIO capability bit to the data returned by
MODE_SENSE commands.  That convinces the guest kernel to determine what
kind of media is present.

Arguably Linux could be smarter about this, but it's my guess there are
few (if any) hardware CDROM drives that don't set the bit, and there are
a large number of Linux distros that exhibit this problem.

  • Implement LSI53C895A quirks exposed by OpenServer (Justin Chevrier). ...
    9167a69a 
    After going through the debug log and scratching my head for quite some
time. I found the following:

The problem was with this block move:

lsi_scsi: SCRIPTS dsp=0fae8e50 opcode 01000028 arg 00f63c40
lsi_scsi: DMA addr=0x00f63c40 len=36

The number of bytes to be transferred (len) should be 40 which corresponds
to the block transfer of length 0x28 (from opcode 01000028). Instead we
have a length of 36 (0x24). The code responsible for this is (in
'lsi_do_dma'):

if (count > s->current_dma_len)
   count = s->current_dma_len;

Basically we're overwriting the length 40 with the value 36 which I
think we just left over in that variable from an earlier transfer. In my
patch below I initialize s->current_dma_len to s->dbc before we begin
the DMA transfer during Data In phase.

The attached patch gets Openserver 5.0.5 past the hardware detection
(and it lists the hard drive to boot, woohoo). It appears to stop a
little while later (doesn't seem SCSI related), but it's been so long since
I've booted Openserver I'm not sure what's supposted to happen after the HW
detection using the boot/root disks.

Props go to Craig Ringer for the initial post and the code that he posted
some of which is in this patch.

  • SM501 emulation for R2D-SH4 ...
    ffd39257 
    This patch adds minimum emulation of SM501 multifunction device,
whose main feature is 2D graphics.  It is one of the peripheral
of R2D, the SH4 evaluation board.  We can see TUX printed on the
QEMU console.

  • Add KVM support to QEMU ...
    7ba1e619 
    This patch adds very basic KVM support.  KVM is a kernel module for Linux that
allows userspace programs to make use of hardware virtualization support.  It
current supports x86 hardware virtualization using Intel VT-x or AMD-V.  It
also supports IA64 VT-i, PPC 440, and S390.

This patch only implements the bare minimum support to get a guest booting.  It
has very little impact the rest of QEMU and attempts to integrate nicely with
the rest of QEMU.

Even though this implementation is basic, it is significantly faster than TCG.
Booting and shutting down a Linux guest:

w/TCG:  1:32.36 elapsed  84% CPU

w/KVM:  0:31.14 elapsed  59% CPU

Right now, KVM is disabled by default and must be explicitly enabled with
 -enable-kvm.  We can enable it by default later when we have had better
testing.
