This adds a common board file for almost all of the "simple" PowerPC 44x boards that exist today. This is intended to be a single place to add support for boards that do not differ in platform support from most of the evaluation boards that are used as reference platforms. Boards that have specific requirements or custom hardware setup should still have their own board.c file. Signed-off-by: NJosh Boyer <jwboyer@linux.vnet.ibm.com>

If the firmware page size used for collaborative memory overcommit is 4k, but the kernel is using 64k pages, the page loaning is currently broken as it only marks the first 4k page of each 64k page as loaned.

Based on an original patch from Christoph Hellwig <hch@lst.de>. Currently, there is a possible reference-after-free in the spusched code - contexts may be freed after we have released their state_mutex in spusched_tick and find_victim. This change takes a reference to the context before releasing the mutex, so that the context doesn't get destroyed. Signed-off-by: NJeremy Kerr <jk@ozlabs.org>

Currently, spu_run ignores the npc argument for contexts created with SPU_CREATE_NOSCHED. While this is correct for isolated contexts, there's no need to enforce the npc restriction on non-isolated NOSCHED contexts. This means that NOSCHED contexts can only ever run with an entry point of 0x0. This change to spu_run_init allows setting of the npc (and, while we're at it, the privcntl) for non-isolated NOSCHED contexts. This allows us to run NOSCHED contexts from any entry point.

When using the "sccdbg" option to route early kernel messages and xmon to the SCC serial port on PowerMacs, when this wasn't the configured output port of Open Firmware, we initialize the baudrate to 57600bps.

由 FUJITA Tomonori 提交于
Add per-device dma_mapping_ops support for CONFIG_X86_64 as POWER architecture does: This enables us to cleanly fix the Calgary IOMMU issue that some devices are not behind the IOMMU (http://lkml.org/lkml/2008/5/8/423). 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 adds functionality to the gpio-lib subsystem to make it possible to enable the gpio-lib code even if the architecture code didn't request to get it built in. The archtitecture code does still need to implement the gpiolib accessor functions in its asm/gpio.h file. This patch adds the implementations for x86 and PPC. With these changes it is possible to run generic GPIO expansion cards on every architecture that implements the trivial wrapper functions. Support for more architectures can easily be added.

To support Cooperative Memory Overcommitment (CMO), we need to check for failure from some of the tce hcalls. These changes for the pseries platform affect the powerpc architecture; patches for the other affected platforms are included in this patch. pSeries platform IOMMU code changes: * platform TCE functions must handle H_NOT_ENOUGH_RESOURCES errors and return an error. Architecture IOMMU code changes: * Calls to ppc_md.tce_build need to check return values and return DMA_MAPPING_ERROR for transient errors. Architecture changes: * struct machdep_calls for tce_build*_pSeriesLP functions need to change to indicate failure. * all other platforms will need updates to iommu functions to match the new calling semantics; they will return 0 on success. The other platforms default configs have been built, but no further testing was performed.

At the moment the fixed mapping is by default strongly ordered (the iommu_fixed=weak boot option must be used to make the fixed mapping weakly ordered). If we're on a setup where the southbridge is being used in endpoint mode (triblade and CAB boards) the default should be a weakly ordered fixed mapping. This adds a check so that if a node of type pcie-endpoint can be found in the device tree the fixed mapping is set to be weak by default (but can be overridden using iommu_fixed=strong).

This patch removes the old kgdb reminants from ARCH=powerpc and implements the new style arch specific stub for the common kgdb core interface. It is possible to have xmon and kgdb in the same kernel, but you cannot use both at the same time because there is only one set of debug hooks. The arch specific kgdb implementation saves the previous state of the debug hooks and restores them if you unconfigure the kgdb I/O driver. Kgdb should have no impact on a kernel that has no kgdb I/O driver configured. Signed-off-by: NJason Wessel <jason.wessel@windriver.com>
