2013-06-24ide: Add handler to ide_cmd_tableKevin Wolf1-58/+86
As a preparation for moving all IDE commands into their own function like in the ATAPI code, introduce a 'handler' callback to ide_cmd_table. Commands using this new infrastructure get some things handled automatically: * The BSY flag is set before calling the handler (in order to avoid bugs like the one fixed in f68ec837) and reset on completion. * The (obsolete) DSC flag in the status register is set on completion if the command is flagged with SET_DSC in the command table * An IRQ is triggered on completion. * The error register and the ERR flag in the status register are cleared before calling the handler and on completion it is asserted that either none or both of them are set. No commands are converted at this point. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>

2013-06-06ide: Set BSY bit during FLUSHAndreas Färber1-0/+1
The implementation of the ATA FLUSH command invokes a flush at the block layer, which may on raw files on POSIX entail a synchronous fdatasync(). This may in some cases take so long that the SLES 11 SP1 guest driver reports I/O errors and filesystems get corrupted or remounted read-only. Avoid this by setting BUSY_STAT, so that the guest is made aware we are in the middle of an operation and no ATA commands are attempted to be processed concurrently. Addresses BNC#637297.

2013-05-20ide/macio: fix wrong opaque with TRIM supportAurelien Jarno1-1/+1
Commit 215e47b9 enabled TRIM by default, which revealed a bug in TRIM support for the IDE macio emulation driver, introduced in d353fb72. The call to dma_bdrv_io() is using a wrong opaque of type IDEState instead of DBDMA_io. This patch fixes that.

2013-05-08ide: Reset BMIDEA bit when the bus master is stoppedKevin Wolf1-0/+1
The device is supposed to reset the Bus Master IDE Active bit in the status register when 0 is written to the Start/Stop Bus Master bit in the command register. In the common cases this happens automatically because bdrv_drain_all() flushes the requests, but with a large PRDT it could remain set. Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2013-05-08ahci: Don't allow creating slave drivesKevin Wolf9-9/+18
An IDE bus provided by AHCI can only take a single IDE drive. If you add a drive as slave, qemu used to accept the command line but the device wouldn't be actually usable. Catch the situation instead and error out. Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2013-04-15ide: refuse WIN_READ_NATIVE_MAX on empty deviceStefan Hajnoczi1-0/+4
What is the highest addressable sector on an empty CD-ROM? Nothing is addressable so produce an error. This patch prevents a divide-by-zero in ide_set_sector() since s->sectors and s->heads would be 0. Not to mention that a sector=-1 argument would be nonsense. Note that WIN_READ_NATIVE_MAX can be triggered using hdparm -N 1024 /dev/cdrom. The LBA bit will be set to 1 though, so the only easy way to go down the ide_set_sector() CHS code path which divides by zero is to comment out the s->select & 0x40 case for testing.

Many of these should be cleaned up with proper qdev-/QOM-ification. Right now there are many catch-all headers in include/hw/ARCH depending on cpu.h, and this makes it necessary to compile these files per-target. However, fixing this does not belong in these patches.

2013-02-22blockdev: enable discard by defaultPaolo Bonzini1-1/+4
Because discard is now a host parameter, we can always fake it as enabled in the guest. This is an extension of the current choice to ignore "not supported" errors from the host when discard_granularity is set to nonzero. The default granularity is set to the logical block size or 4k, whichever is largest, because cluster sizes below 4k are rarely used and 4K is a typical block size for files.

2013-01-10Make all static TypeInfos constAndreas Färber7-12/+12
Since 39bffca2030950ef6efe57c2fac8327a45ae1015 (qdev: register all types natively through QEMU Object Model), TypeInfo as used in the common, non-iterative pattern is no longer amended with information and should therefore be const. Fix the documented QOM examples: sed -i 's/static TypeInfo/static const TypeInfo/g' include/qom/object.h Since frequently the wrong examples are being copied by contributors of new devices, fix all types in the tree: sed -i 's/^static TypeInfo/static const TypeInfo/g' */*.c sed -i 's/^static TypeInfo/static const TypeInfo/g' */*/*.c This also avoids to piggy-back these changes onto real functional changes or other refactorings.
