2010-12-20wdt_ib700: Fix accidental use of SoftFloat int64 typeAndreas Färber1-1/+1

2010-12-18sparc32: ledma extra registersBob Breuer2-8/+23
ledma has 0x20 bytes of registers according to OBP, and at least Solaris9 reads the 5th register which is beyond what we've mapped. So let's setup a flag (inspired by a previous patch from Blue Swirl) to identify ledma from espdma, and map another 16 bytes of registers which return 0.

2010-12-17ide: Register vm change state handler once onlyStefan Hajnoczi3-28/+58
We register the vm change state handler in a PCI BAR map() function. This function can be called multiple times throughout the lifetime of a PCI IDE device. This results in duplicate vm change state handlers being register, none of which are ever unregistered. Instead, register the vm change state handler in the device's init function once and for all. piix tested, cmd646 and via not tested.

2010-12-17ide: move transfer_start after variable modificationAlexander Graf1-4/+4
We hook into transfer_start and immediately call the end function for ahci. This means that everything needs to be in place for the end function when we start the transfer, so let's move the function down to where all state is in place.

2010-12-12Watchdog: disable watchdog timer when hard-rebooting a guest.Richard W.M. Jones2-5/+20
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.

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 Kohl1-18/+21
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.

2010-12-11e1000: Make little endianAlexander Graf1-9/+2
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.
