| | | | | | | | | | | | | | | | | | | | | | Raise the DMA block size limit from 2048 bytes to the maximum supported by the DMA controllers on the chip (64KB on Au1100, 4MB on Au1200). This gives a very small performance boost and apparently fixes an oops when MMC-DMA and network traffic are active at the same time.

* avr32: some mmc/sd cleanupsDavid Brownell2008-07-27
| | | | | | | | | | | | | | | | | | | | Minor cleanups for the MMC/SD support on avr32: - Make at32_add_device_mci() properly initialize "missing" platform data ... so boards like STK1002 won't try GPIO 0. - Switch over to gpio_is_valid() instead of testing for only one designated value. - Provide STK1002 platform data for the unlikely case that switches are set so first Ethernet controller isn't in use. (That's the only way to get card detect and writeprotect switch sensing on the STK1000.) And get rid of one "unused variable" warning.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For each card successfully added to the bus, create a subdirectory under the host's debugfs root with information about the card. At the moment, only a single file is added to the card directory for all cards: "state". It reflects the "state" field in struct mmc_card, indicating whether the card is present, readonly, etc. For MMC and SD cards (not SDIO), another file is added: "status". Reading this file will ask the card about its current status and return it. This can be useful if the card just refuses to respond to any commands, which might indicate that the card state is not what the MMC core thinks it is (due to a missing stop command, for example.)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The original intention was to write a zero byte to mmc to force spi signals to low when doing power off. Somehow the spi_w8r8 call got there so a read followed the write of single zero byte. This patch changes that to simple write of zero byte without the following read. This way the power off is more reliable and completely sufficient.

| * | dma-mapping: add the device argument to dma_mapping_error()FUJITA Tomonori2008-07-26

I think that per-device dma_mapping_ops support would be also helpful for KVM people to support PCI passthrough but Andi thinks that this makes it difficult to support the PCI passthrough (see the above thread). So I CC'ed this to KVM camp. Comments are appreciated. A pointer to dma_mapping_ops to struct dev_archdata is added. If the pointer is non NULL, DMA operations in asm/dma-mapping.h use it. If it's NULL, the system-wide dma_ops pointer is used as before. If it's useful for KVM people, I plan to implement a mechanism to register a hook called when a new pci (or dma capable) device is created (it works with hot plugging). It enables IOMMUs to set up an appropriate dma_mapping_ops per device. The major obstacle is that dma_mapping_error doesn't take a pointer to the device unlike other DMA operations. So x86 can't have dma_mapping_ops per device. Note all the POWER IOMMUs use the same dma_mapping_error function so this is not a problem for POWER but x86 IOMMUs use different dma_mapping_error functions. The first patch adds the device argument to dma_mapping_error. The patch is trivial but large since it touches lots of drivers and dma-mapping.h in all the architecture. This patch: dma_mapping_error() doesn't take a pointer to the device unlike other DMA operations. So we can't have dma_mapping_ops per device. Note that POWER already has dma_mapping_ops per device but all the POWER IOMMUs use the same dma_mapping_error function. x86 IOMMUs use device argument.

|/ | | | | | | | | | | | | | | | | This patch does a few small cleanups around the atmel mci platform code and in the atmel-mci driver. The platform changes simply removes an unused variable, uses the fact that by the end we always have some form of platform data and notes that GPIO_PIN_NONE != 0. This last point could cause the incorrect attempt to twice reserve pin PA0. While we've got the hood up, add linux/err.h to the atmel-mci.c include list. It needs it and generally pulls it by voodoo but I did once stumble across a config which don't build. This is against Linus' latest git.
