2010-12-11Add bootindex parameter to net/block/fd deviceGleb Natapov
If bootindex is specified on command line a string that describes device in firmware readable way is added into sorted list. Later this list will be passed into firmware to control boot order. Signed-off-by: Gleb Natapov <gleb@redhat.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

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

2010-12-11isa_mmio: 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.

2010-12-11dbdma: Make little endianAlexander Graf
The device is only used on big endian systems, but always byte swaps. That's a very good indicator that it's actually a little endian device ;-). Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2010-12-11Make simple io mem handler endian awareAlexander Graf
As an alternative to the 3 individual handlers, there is also a simplified io mem hook function. To be consistent, let's add an endianness parameter there too. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
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.

2010-11-29ide: Reset current_addr after stopping DMAKevin Wolf
Whenever SSBM is reset in the command register all state information is lost. Restarting DMA means that current_addr must be reset to the base address of the PRD table. The OS is not required to change the base address register before starting a DMA operation, it can reuse the value it wrote for an earlier request.

2010-11-25scsi: Move sense handling into the driverHannes Reinecke

2010-11-25scsi: Return SAM status codesHannes Reinecke
Traditionally, the linux stack is using SCSI status codes which are shifted by one as compared to those defined in SAM. A SCSI emulation should naturally return the SAM defined codes, not the linux ones. So to avoid any confusion this patch modifies the existing definitions to match those found in SAM and removes any (now obsolete) byte-shift from the returned status codes.

2010-11-25scsi: Increase the number of possible devicesHannes Reinecke
The SCSI parallel interface has a limit of 8 devices, but not the SCSI stack in general. So we should be removing the hard-coded limit and use MAX_SCSI_DEVS instead. And we only need to scan those devices which are allocated by the bus.

2010-11-24scsi-disk: Move active request assertsStefan Hajnoczi
SCSI read/write requests should not be re-issued before the current fragment of I/O completes. There are asserts in scsi-disk.c that guard this constraint but they trigger on SPARC Linux 2.4. It turns out that the asserts are too early in the code path and don't allow for read requests to terminate. Only the read assert needs to be moved but move the write assert too for consistency.
