2011-08-22e1000: use MII status register for link up/downBjørn Mork
Some guests will use the standard MII status register to verify link state. They will not notice link changes unless this register is updated. Verified with Linux 3.0 and Windows XP guests. Without this patch, ethtool will report speed and duplex as unknown when the link is down, but still report the link as up. This is because the Linux e1000 driver checks the mac_reg[STATUS] register link state before it checks speed and duplex, but uses the phy_reg[PHY_STATUS] register for the actual link state check. Fix by updating both registers on link state changes. Linux guest before: (qemu) set_link e1000.0 off kvm-sid:~# ethtool eth0 Settings for eth0: Supported ports: [ TP ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Supports auto-negotiation: Yes Advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Advertised pause frame use: No Advertised auto-negotiation: Yes Speed: Unknown!

2011-08-17versatilepb: Implement SYS_CLCD mux control register bitsPeter Maydell
On the Versatile PB, PL110 graphics adaptor only natively supports 5551 pixel format; an external mux swaps bits around to allow RGB565 and BGR565, under the control of bits [1:0] in the SYS_CLCD system register. Implement these SYS_CLCD register bits, and use a gpio line to feed them out of the system register model, across the versatilepb board and into the pl110 so we can select the right format. This is necessary as recent Linux versatile kernels default to programming the CLCD and mux for 16 bit BGR rather than 16 bit RGB. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>

Model the PL111 CLCD controller. This is a minor variation on the PL110; the major programmer visible differences are support for hardware cursor (unimplemented) and two new pixel formats. Since syborg_fb.c borrows the pl11x pixel drawing routines, we also update it to cope with the new slightly larger array of function pointers. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>

This will let SCSIBus detect requests sent to an invalid LUN, and handle them itself. However, there will be still support for only one LUN per target Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2011-08-12scsi: introduce SCSICommandPaolo Bonzini
This struct is currently unnamed. Give it a name and use it explicitly to decouple (some parts of) CDB parsing from SCSIRequest. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2011-08-12scsi: pass cdb already to scsi_req_newPaolo Bonzini
Right now the CDB is not passed to the SCSIBus until scsi_req_enqueue. Passing it to scsi_req_new will let scsi_req_new dispatch common requests through different reqops. Moving the memcpy to scsi_req_new is a hack that will go away as soon as scsi_req_new will also take care of the parsing.
