2010-09-08scsi-disk: add some optional scsi commandsBernhard Kohl
I use a legacy OS which depends on some optional SCSI commands. In fact this implementation does nothing special, but provides minimum support for the following commands: REZERO UNIT WRITE AND VERIFY(10) WRITE AND VERIFY(12) WRITE AND VERIFY(16) MODE SELECT(6) MODE SELECT(10) SEEK(6) SEEK(10) Signed-off-by: Bernhard Kohl <bernhard.kohl@nsn.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

The DBD bit does not work as expected. SCSI-Spec: http://ldkelley.com/SCSI2/SCSI2/SCSI2-08.html#8.2.10 "A disable block descriptors (DBD) bit of zero indicates that the target may return zero or more block descriptors in the returned MODE SENSE data (see 8.3.3), at the target's discretion.

2010-09-08scsi-disk: fix the block descriptor returned by the MODE SENSE commandBernhard Kohl
The block descriptor contains the number of blocks, not the highest LBA. Real hard disks return 0 if the number of blocks exceed the maximum 0xFFFFFF. SCSI-Spec: http://ldkelley.com/SCSI2/SCSI2/SCSI2-08.html#8.3.3 "The number of blocks field specifies the number of logical blocks on the medium to which the density code and block length fields apply. A value of zero indicates that all of the remaining logical blocks of the logical unit shall have the medium characteristics specified."

2010-09-08scsi-disk: respect the page control (PC) field in the MODE SENSE commandBernhard Kohl
The page control (PC) field defines the type of mode parameter values to be returned in the mode pages: PC=0 : Current values PC=1 : Changeable values PC=2 : Default values PC=3 : Saved values The current implementation always returns the same type of parameters. This is OK for Current and Default values as we don't support changes to be done by the MODE SELECT command. For Saved values the following applies (implemented by this patch): "A PC field value of 3h requests that the target return the saved values of the mode parameters. Implementation of saved page parameters is optional. Mode parameters not supported by the target shall be set to zero. If saved values are not implemented, the command shall be terminated with CHECK CONDITION status, the sense key set to ILLEGAL REQUEST and the additional sense code set to SAVING PARAMETERS NOT SUPPORTED." For Changeable values the following applies (implemented by this patch): "A PC field value of 1h requests that the target return a mask denoting those mode parameters that are changeable. In the mask, the fields of the mode parameters that are changeable shall be set to all one bits and the fields of the mode parameters that are non-changeable (i.e. defined by the target) shall be set to all zero bits." In newer versions of the SCSI-2 spec the following clause was added. "If the logical unit does not implement changeable parameters mode pages and the device server receives a MODE SENSE command with 01b in the PC field, then the command shall be terminated with CHECK CONDITION status, with the sense key set to ILLEGAL REQUEST, and the additional sense code set to INVALID FIELD IN CDB." This was not yet included in the SCSI-2 Working Drafts from 1986-1993. I assume that the variant to return CHECK CONDITION for PC=1 is not widely implemented by real devices. I have a legacy OS which fails, if MODE_SENSE returns non GOOD for PC=1. So for highest compatibility I implemented the former variant with this patch. The last Working Draft X3T9.2 Rev. 10L 7-SEP-93 can be found here: http://ldkelley.com/SCSI2/SCSI2/SCSI2-08.html#8.2.10 In mode_sense_page() this patch also avoids multiple hard coded definitions of the same mode page length. Instead I use the varable p[1]. In fact the returned length of the mode pages 4 and 5 were wrong (2 bytes less).

2010-08-26PPC: Add PV hypercall transport through fw_cfgAlexander Graf
On KVM for PPC we need to tell the guest which instructions to use when doing a hypercall. The clean way to do this is to go through an ioctl from userspace and passing it on to the guest using the device tree. So let's do the qemu part here: read out the hypercall and pass it on to the guest's fw_cfg so openBIOS can read it out and expose it again. Signed-off-by: Alexander Graf <agraf@suse.de>

2010-08-22VGA: Don't register deprecated VBE rangeAlex Williamson
Old versions of the BOCHs VGA BIOS (cira 2003) made use of VBE registers at 0xff80/81. In VBE API version 0xb0c2 these were moved to 0x1ce/cf. Unfortunately, QEMU still registers handlers for the old range. If a guest attempts to assign an I/O device overlapping this region, QEMU exits with a hw_error. Windows guests seem to like to assign I/O devices to the high end of the address space, so it's pretty easy to hot add an rtl8139 to a Win2k8 guest and trigger the bug. I can't find any reason to register these handlers, so let's remove the cruft. Signed-off-by: Alex Williamson <alex.williamson@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2010-08-22pckbd: support for commands 0xf0-0xff: Pulse output bitBernhard Kohl
I have a guest OS which sends the command 0xfd to the keyboard controller during initialization. To get rid of the message "qemu: unsupported keyboard cmd=0x%02x\n" I added support for the pulse output bit commands. I found the following explanation here: http://www.win.tue.nl/~aeb/linux/kbd/scancodes-11.html#ss11.3 Command 0xf0-0xff: Pulse output bit Bits 3-0 of the output port P2 of the keyboard controller may be pulsed low for approximately 6 µseconds. Bits 3-0 of this command specify the output port bits to be pulsed. 0: Bit should be pulsed. 1: Bit should not be modified. The only useful version of this command is Command 0xfe. (For MCA, replace 3-0 by 1-0 in the above.) Command 0xfe: System reset Pulse bit 0 of the output port P2 of the keyboard controller. This will reset the CPU.

2010-08-03ide: Avoid canceling IDE DMAAndrea Arcangeli
The reason for not actually canceling the I/O is because with virtualization and lots of VM running, a guest fs may mistake a overload of the host, as an IDE timeout. So rather than canceling the I/O, it's safer to wait I/O completion and simulate that the I/O has completed just before the io cancellation was requested by the guest. This way if ntfs or an app writes data without checking for -EIO retval, and it thinks the write has succeeded, it's less likely to run into troubles. Similar issues for reads. Furthermore because the DMA operation is splitted into many synchronous aio_read/write if there's more than one entry in the SG table, without this patch the DMA would be cancelled in the middle, something we've no idea if it happens on real hardware too or not. Overall this seems a great risk for zero gain. This approach is sure safer than previous code given we can't pretend all guest fs code out there to check for errors and reply the DMA if it was completed partially, given a timeout would never materialize on a real harddisk unless there are defective blocks (and defective blocks are practically only an issue for reads never for writes in any recent hardware as writing to blocks is the way to fix them) or the harddisk breaks as a whole.
