Since most property types do not have a parse property now, this was broken. Fix it by looking at the setter instead.

2012-05-14usb-host: handle guest-issued clear haltGerd Hoffmann
Most important here is to update our internal endpoint state so we know the endpoint isn't in halted state any more. Without this usb-host tries to clear halt again with the next data transfer submitted. Doing this twice is (a) not correct and (b) confuses some usb devices, rendering them non-functional in the guest. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2012-05-13mips_fulong2e: Don't register "cpu" VMState twiceJuan Quintela
We have the following simplified callgraph in mips_fulong2e_init(): cpu_init() => cpu_mips_init() object_new() mips_cpu_initfn() cpu_exec_init() register_savevm(NULL, "cpu", cpu_index, CPU_SAVE_VERSION, cpu_save, cpu_load, env) register_savevm(NULL, "cpu", 0, 3, cpu_save, cpu_load, env) CPU_SAVE_VERSION is defined as 3 in target-mips/cpu.h. fulong2e instantiates one CPU, so its cpu_index is 0. Thus the two are fully identical. Therefore just remove the second call in fulong2e.

2012-05-08rtl8139: fix regression in TxStatus/TxAddr readAvi Kivity
Commit afe0a595356192 added byte reads for TxStatus/TxAddr, but broke 32-bit reads; the mask generation (1 << (8 * size)) - 1 is unspecified in C for size >= sizeof(int), and in fact returns 0 on x86. Fix by using a larger type. Fixes (at least) Fedora 9 i386 with -machine kernel_irqchip=on. I didn't see it with the qemu APIC implementation; may be due to timing or (more likely) a tester error.

2012-05-07hw/ac97: Mask out the EAPD bit on Powerdown Ctrl/Stat writesHans de Goede

2012-05-07hw/ac97: Mask out unused bits of volume controlsHans de Goede
The Linux ac97 drivers does a number of register read/write tests to see how much resolution a volume control actually has. This patch takes this into account by masking out any bits written to a volume control reg which should not be there according to the spec. After this the Linux ac97 driver correctly uses a range of 0 - 0x1f for the PCM out volume, as stated in the spec, and we can fix the FIXME in update_combined_volume_out(). This patch was also tested with a Windows XP guest without any issues. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: malc <av1474@comtv.ru>

After commit 19677a380a70348134ed7650b294522617eb03fc: "hw/ac97: add support for volume control" We are (correctly) using AC97_Record_Gain_Mute and not AC97_Line_In_Volume_Mute for recording volume, but various places in hw/ac97 were still assumimg that we are using AC97_Line_In_Volume_Mute for record volume control, this patch fixes this.

2012-05-07hw/ac97: Make a bunch of mixer registers read onlyHans de Goede
The Linux ac97 driver tries to see if optional things like video input volume control are available in 2 ways: 1) See if the mute bit is set after reset, if it is no further tests are done 2) If the mute bit is not set it does a write/read test of the mute bit This patch changes our ac97 to conform to what the Linux driver expects, it initializes registers for things which we don't emulate to 0 (so the mute bit is not set) and makes them read only. This causes Linux to now longer show the following (functionless) controls in alsamixer: Master Mono vol + mute 3d Control toggle PCM out pre / post 3d select Surround toggle CD vol + mute Mic vol + mute Mic boost toggle Mic mic1 / mic2 select Video vol + mute Phone vol + mute Beep mono vol + mute Aux vol + mute Mono "output mic" / "mix" select Sigmatel 4 speaker stereo toggle Sigmatel ADC 6Db att toggle Sigmatel DAC 6Db att toggle This patch was also tested with a Windows XP guest and there it also makes a number of functionless mixer controls go away.

2012-05-07scsi: parse 16-byte tape CDBsPaolo Bonzini

2012-05-07scsi: do not report bogus overruns for commands in the 0x00-0x1F rangePaolo Bonzini
Interpreting cdb[4] == 0 as a request to transfer 256 blocks is only needed for READ_6 and WRITE_6. No other command in that range needs that special-casing, and the resulting overrun breaks scsi-testsuite's attempt to use command 2 as a known-invalid command.

2012-05-07scsi-disk: add dpofua propertyPaolo Bonzini
Linux expects REQ_FUA to be advertised only if WRITE+FUA is faster than WRITE+SYNCHRONIZE CACHE, so we should not set the DPOFUA bit. However, it is useful to have it for testing purposes, so add a qdev property to set it. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-05-07scsi: change "removable" field to host many featuresPaolo Bonzini

2012-05-04scsi: Specify the xfer direction for UNMAP and ATA_PASSTHROUGH commandsRonnie Sahlberg
scsi_cmd_xfer_mode() is used to specify the xfer direction for SCSI commands that come in from the guest. If the direction is set incorrectly this will eventually cause QEMU to kernel-panic the guest. Add UNMAP and ATAPASSTHROUGH as commands that send data to the device. Without this change, recent kernels will send both UNMAP as well as ATAPASSTHROUGH commands to any /dev/sg* device, which due to the incorrect xfer direction very quickly causes the guest kernel to crash. Example causing a crash without the patch applied: ./x86_64-softmmu/qemu-system-x86_64 -m 1024 -enable-kvm -cdrom linuxmint-12-gnome-dvd-64bit.iso -drive file=/dev/sg4,if=scsi,bus=0,unit=6 Signed-off-by: Ronnie Sahlberg <ronniesahlberg@gmail.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2012-05-04scsi: fix refcounting for readsPaolo Bonzini
Recently introduced FUA support also gave us a use-after-free of the BlockAcctCookie within a SCSIDiskReq, due to unbalanced reference counting. The patch fixes this by making scsi_do_read look like a combination of scsi_*_complete + scsi_*_data. It does both a ref (like scsi_read_data) and an unref (like scsi_flush_complete).
