2010-12-17ide: fix whitespace gap in ide_exec_cmdAlexander Graf
Now that we have the function split out, we have to reindent it. In order to increase the readability of the actual functional change, this is split out. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2010-12-17ide: split ide command interpretation offAlexander Graf
The ATA command interpretation code can be used for PATA and SATA interfaces alike. So let's split it out into a separate function. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2010-12-12Watchdog: disable watchdog timer when hard-rebooting a guest.Richard W.M. Jones
This commit causes the watchdog timer to be reset when a guest is hard-rebooted. The failure case previously was as follows: (a) guest boots, watchdog is enabled (b) guest does a reset eg: echo 'b' > /proc/sysrq-trigger (note that an ordinary /sbin/reboot wouldn't hit this case since as the watchdog daemon is shut down, the daemon would properly disable the watchdog device) (c) the reboot takes longer than the remaining time on the watchdog (d) the watchdog therefore fires during the reboot (e) probably the VM would just reboot again at this point which is pretty benign, but it could depend on the action that the user had selected for the watchdog Now we use the qdev reset function to register a reset handler which disables the timer. Note the handler is called _either_ just after init _or_ when the guest reboots. In the i6300esb case there is a small refactoring of the code so that the device's internal state is now fully restored to defaults on a reboot. Signed-off-by: Richard W.M.

2010-12-11Change fw_cfg_add_file() to get full file path as a parameter.Gleb Natapov
Change fw_cfg_add_file() to get full file path as a parameter instead of building one internally. Two reasons for that. First caller may need to know how file is named. Second this moves policy of file naming out from fw_cfg. Platform may want to use more then two levels of directories for instance.

2010-12-11wdt_i6300esb: register a reset functionBernhard Kohl
The device shall set its default hardware state after each reset. This includes that the timer is stopped which is especially important if the guest does a reboot independantly of a watchdog bite. I moved the initialization of the state variables completely from the init to the reset function which is called right after init during the first boot and afterwards during each reboot.

2010-12-11usb_ohci: Always use little endianAlexander Graf

2010-12-11e1000: Make little endianAlexander Graf
The e1000 has compatibility code to handle big endianness which makes it mandatory to be recompiled on different targets. With the generic mmio endianness solution, there's no need for that anymore. We just declare all mmio to be little endian and call it a day. Because we don't depend on the target endianness anymore, we can also move the driver over to Makefile.objs.

2010-12-11pci-host: Delegate bswap to mmio layerAlexander Graf
The only reason we have bswap versions of the pci host code is that most pci host devices are little endian. The ppc e500 is the only odd one here, being big endian. So let's directly pass the endianness down to the mmio layer and not worry about it on the pci host layer.

2010-12-11Make simple io mem handler endian awareAlexander Graf

2010-12-11Add endianness as io mem parameterAlexander Graf
As stated before, devices can be little, big or native endian. The target endianness is not of their concern, so we need to push things down a level. This patch adds a parameter to cpu_register_io_memory that allows a device to choose its endianness. For now, all devices simply choose native endian, because that's the same behavior as before.

2010-12-09pci/aer: fix interrupt on config writeMichael S. Tsirkin
config write handling for aer seems broken: For example, it won't clear a level interrupt when command register is set to 0.

2010-12-09pci/aer: fix error injectionMichael S. Tsirkin

2010-12-09pci: untangle pci/msi dependencyMichael S. Tsirkin

2010-12-09pci: make command SERR bit writableIsaku Yamahata

SYNOPSIS size[4] Tfsync tag[2] fid[4] datasync[4] size[4] Rfsync tag[2] DESCRIPTION The Tfsync transaction transfers ("flushes") all modified in-core data of file identified by fid to the disk device (or other permanent storage device) where that file resides. If datasync flag is specified data will be fleshed but does not flush modified metadata unless that metadata is needed in order to allow a subsequent data retrieval to be correctly handled.
