2012-07-26scsi-disk: move all non-DMA commands to scsi_disk_emulate_commandPaolo Bonzini
We want to use separate SCSIReqOps for emulated commands needing an allocated buffer vs. those that are zerocopy when the HBA supports S/G lists. Ensure that all of the former are in scsi_disk_emulate_command. Commands that do not have any parameters are more similar to emulated commands, so also move them, even if they do I/O. Finally, MODE SELECT and MODE SELECT(10) are broken because we do not yet support passing parameter data _to_ emulated commands, so disable them. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

By making discard asynchronous, we can reuse all the error handling code that is used for other commands. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-07-26scsi-disk: let the user customize vendor and product nameDmitry Fleytman
This patch adds two new properties vendor and product to SCSI disks. These options let the user customize the inquiry data returned by the disk.

2012-07-26scsi-block: remove properties that are not relevant for passthroughPaolo Bonzini
scsi-block is a passthrough device and does not allow customization of vendor, product, removable, DPOFUA, block size or any other piece of information. Thus, drop DEFINE_SCSI_DISK_PROPERTIES() from the list of qdev properties. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-07-26lsi: avoid redundant tests of s->current != NULLPaolo Bonzini
Simplify the code by checking against req->hba_private directly, and asserting that it is non-NULL before a command is completed or canceled. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-07-26lsi: introduce lsi_request_freePaolo Bonzini
Split the common bits of lsi_request_cancelled and lsi_command_complete out to a new function. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-07-26lsi: use qdev_reset_allPaolo Bonzini
By first resetting the devices, lsi_soft_reset will find the queue already cleared so there is no need to do that forcibly (which may also leak SCSIRequests, and/or worse due to dangling references to the lsi_request in the hba_private field). Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-07-26megasas: fix misuse of scsi_req_abortPaolo Bonzini
scsi_req_abort is for terminating a command with a non-zero status. The ABORT task management function is invoked by scsi_req_cancel. In fact, ABORTED_COMMAND is a sense key, not a SAM status code. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-07-26megasas: Replace trace_megasas_dcmd_dump_frame()Hannes Reinecke
trace_megasas_dcmd_dump_frame() takes 9 arguments, which is rather much. Plus the trace infrastructure doesn't support it. As we can get the information via other means it's pointless to have it in the driver, so rather use some proper trace point here and remove the old one.

Since commit 541dc0d47f10973c241e9955afc2aefc96adec51, some new packed structures were added without using QEMU_PACKED. QEMU_PACKED is needed for compilations with MinGW.

2012-07-20hw/vexpress.c: Allow >4GB of RAM for Cortex-A15 daughterboardPeter Maydell
Now that we have LPAE support and can handle passing 64 bit RAM sizes to Linux via the device tree, we can lift the restriction in the Versatile Express A15 daughterboard model on not having more than 2GB of RAM.

All current users (IDE, SCSI and virtio-blk) happen to share this 20 characters limit. Still, it should be left to device models. They already enforce their limits. They have to, as the DriveInfo limit only affects legacy -drive serial=..., not the qdev properties. usb-storage, which doesn't limit serial number length, also uses DriveInfo for -usbdevice.

2012-07-17block: Geometry and translation hints are now useless, purge themMarkus Armbruster
There are two producers of these hints: drive_init() on behalf of -drive, and hd_geometry_guess(). The only consumer of the hint is hd_geometry_guess(). The callers of hd_geometry_guess() call it only when drive_init() didn't set the hints. Therefore, drive_init()'s hints are never used. Thus, hd_geometry_guess() only ever sees hints it produced itself in a prior call. Only the first call computes something, subsequent calls just repeat the first call's results. However, hd_geometry_guess() is never called more than once: the device models don't, and the block device is destroyed on unplug. Thus, dropping the repeat feature doesn't break anything now. If a block device wasn't destroyed on unplug and could be reused with a new device, then repeating old results would be wrong. Thus, dropping the repeat feature prevents future breakage. This renders the hints unused. Purge them from the block layer. Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2012-07-17ide: qdev property for BIOS CHS translationMarkus Armbruster
This isn't quite orthodox. CHS translation is firmware configuration, communicated via the RTC's CMOS RAM, not a property of the disk. But it's best to treat it just like geometry anyway. Maintain backward compatibility exactly like for geometry: fall back to DriveInfo's translation, set with -drive trans=... Bonus: info qtree now shows the translation. Except when it shows "auto": that's resolved by pc_cmos_init_late(). To be addressed shortly. Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2012-07-17hd-geometry: Clean up confusing use of prior translation hintMarkus Armbruster
When hd_geometry_guess() picks a geometry, it also picks the appropriate translation, but only when the prior translation hint is BIOS_ATA_TRANSLATION_AUTO. Looks wrong, because such a prior translation would be passed to the BIOS whether it's suitable for the geometry or not. Fortunately, that can't happen. There are just two ways for the translation hint to get set to something other than BIOS_ATA_TRANSLATION_AUTO: drive_init() on behalf of -drive trans=..., and hd_geometry_guess(). Both set it only when they also set a valid geometry hint, i.e. one with a non-zero number of cylinders. Since hd_geometry_guess() returns right away when it finds a valid geometry hint, translation can only be BIOS_ATA_TRANSLATION_AUTO in the remainder of the function. Assert this, and simplify accordingly. Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
