| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch from Deepak Saxena In working on adding 36-bit addressed supersection support to ioremap(), I came to the conclusion that it would be far simpler to do so by just splitting __ioremap() into a main external interface and adding an __ioremap_pfn() function that takes a pfn + offset into the page that __ioremap() can call. This way existing callers of __ioremap() won't have to change their code and 36-bit systems will just call __ioremap_pfn() and we will not have to deal with unsigned long long variables. Note that __ioremap_pfn() should _NOT_ be called directly by drivers but is reserved for use by arch_ioremap() implementations that map 32-bit resource regions into the real 36-bit address and then call this new function.

| * [PATCH] IRQ type flagsRussell King2006-01-081-4/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some ARM platforms have the ability to program the interrupt controller to detect various interrupt edges and/or levels. For some platforms, this is critical to setup correctly, particularly those which the setting is dependent on the device. Currently, ARM drivers do (eg) the following: err = request_irq(irq, ...); set_irq_type(irq, IRQT_RISING); However, if the interrupt has previously been programmed to be level sensitive (for whatever reason) then this will cause an interrupt storm. Hence, if we combine set_irq_type() with request_irq(), we can then safely set the type prior to unmasking the interrupt. The unfortunate problem is that in order to support this, these flags need to be visible outside of the ARM architecture - drivers such as smc91x need these flags and they're cross-architecture. Finally, the SA_TRIGGER_* flag passed to request_irq() should reflect the property that the device would like. The IRQ controller code should do its best to select the most appropriate supported mode.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several counters already have the need to use 64 atomic variables on 64 bit platforms (see mm_counter_t in sched.h). We have to do ugly ifdefs to fall back to 32 bit atomic on 32 bit platforms. The VM statistics patch that I am working on will also make more extensive use of atomic64. This patch introduces a new type atomic_long_t by providing definitions in asm-generic/atomic.h that works similar to the c "long" type. Its 32 bits on 32 bit platforms and 64 bits on 64 bit platforms. Also cleans up the determination of the mm_counter_t in sched.h.

| * [PATCH] madvise(MADV_REMOVE): remove pages from tmpfs shm backing storeBadari Pulavarty2006-01-061-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Here is the patch to implement madvise(MADV_REMOVE) - which frees up a given range of pages & its associated backing store. Current implementation supports only shmfs/tmpfs and other filesystems return -ENOSYS. "Some app allocates large tmpfs files, then when some task quits and some client disconnect, some memory can be released. However the only way to release tmpfs-swap is to MADV_REMOVE". - Andrea Arcangeli Databases want to use this feature to drop a section of their bufferpool (shared memory segments) - without writing back to disk/swap space. This feature is also useful for supporting hot-plug memory on UML. Concerns raised by Andrew Morton: - "We have no plan for holepunching! If we _do_ have such a plan (or might in the future) then what would the API look like? I think sys_holepunch(fd, start, len), so we should start out with that." - Using madvise is very weird, because people will ask "why do I need to mmap my file before I can stick a hole in it?" - None of the other madvise operations call into the filesystem in this manner. A broad question is: is this capability an MM operation or a filesytem operation? truncate, for example, is a filesystem operation which sometimes has MM side-effects. madvise is an mm operation and with this patch, it gains FS side-effects, only they're really, really significant ones." Comments: - Andrea suggested the fs operation too but then it's more efficient to have it as a mm operation with fs side effects, because they don't immediatly know fd and physical offset of the range. It's possible to fixup in userland and to use the fs operation but it's more expensive, the vmas are already in the kernel and we can use them. Short term plan & Future Direction: - We seem to need this interface only for shmfs/tmpfs files in the short term. We have to add hooks into the filesystem for correctness and completeness. This is what this patch does. - In the future, plan is to support both fs and mmap apis also. This also involves (other) filesystem specific functions to be implemented. - Current patch doesn't support VM_NONLINEAR - which can be addressed in the future.

* | [ARM] 3226/1: IXP4xx runtime expansion bus window size configurationDeepak Saxena2006-01-056-27/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch from Deepak Saxena The expansion bus on the IXP46x NPU can be configured for either 32MiB or 16MiB windows and changing the configuration causes the base address for each chip select for each region to change. Because of this, we cannot hardcode the physical base as we currently do. This patch checks the expansion bus configuration registers at runtime to determine the appropriate window size. Note that this requires that the bootloader already configured the device sizes appropriately, but I feel that is valid assumption to make as the bootloader must configure and access the flash window, the output display (LCD, LEDs, etc) window, and other expansion bus devices.

The NAS100D is a consumer device containing a 266MHz Intel IXP420 processor, 16MB of flash, 64MB of RAM, a 160Gb internal IDE hard disk, and 802.11b/g wireless on an Atheros mini-PCI card. Work on porting the latest 2.6.x kernel to this device is being done by the NSLU2-Linux project (the same team who maintains the port to the Linksys NSLU2 device). In particular, the majority of this patch was authored by Alessandro Zummo, based on the work done for MACH_NSLU2 support by the NSLU2-Linux core team of developers. MACH_NAS100D (as implemented by this patch) can be enabled in jumbo ixp4xx kernels without any affect on the other machines supported by that kernel. This patch applies cleanly against 2.6.15-rc7 and should be trivial to apply to later kernel versions. It does not depend upon any other patches.

* [ARM] Remove asm/hardware.h include from SA1100 io.hRussell King2005-11-251-2/+0
| | | | | | | | | | | | | | | | | | | Unfortunately, we have a symbol clash between the SA-1100 header and some drivers. Since everywhere which needs SA1100 specifics includes asm/hardware.h, we don't need to include it in the SA1100 io.h header. In file included from drivers/net/wireless/wavelan_cs.p.h:459, from drivers/net/wireless/wavelan_cs.c:60: drivers/net/wireless/wavelan_cs.h:97:1: warning: "LCSR" redefined In file included from include/asm/arch/hardware.h:56, from include/asm/hardware.h:16, from include/asm/arch/io.h:13, from include/asm/io.h:71, from drivers/net/wireless/wavelan_cs.p.h:433, from drivers/net/wireless/wavelan_cs.c:60: include/asm/arch/SA-1100.h:1907:1: warning: this is the location of the previous definition Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

* [ARM] Add asm/memory.h to asm/numnodes.hRussell King2005-11-211-0/+2
| | | | | | | | Since the defintion of NODES_SHIFT may be overridden in asm/arch/memory.h it's important to include asm/memory.h into asm/numnodes.h to ensure that the correct value is always defined. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
