* | [PATCH] Set CONFIG_ZONE_DMA for arches with GENERIC_ISA_DMAChristoph Lameter2007-02-111-0/+4
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | As Andi pointed out: CONFIG_GENERIC_ISA_DMA only disables the ISA DMA channel management. Other functionality may still expect GFP_DMA to provide memory below 16M. So we need to make sure that CONFIG_ZONE_DMA is set independent of CONFIG_GENERIC_ISA_DMA. Undo the modifications to mm/Kconfig where we made ZONE_DMA dependent on GENERIC_ISA_DMA and set theses explicitly in each arches Kconfig. Reviews must occur for each arch in order to determine if ZONE_DMA can be switched off. It can only be switched off if we know that all devices supported by a platform are capable of performing DMA transfers to all of memory (Some arches already support this: uml, avr32, sh sh64, parisc and IA64/Altix). In order to switch ZONE_DMA off conditionally, one would have to establish a scheme by which one can assure that no drivers are enabled that are only capable of doing I/O to a part of memory, or one needs to provide an alternate means of performing an allocation from a specific range of memory (like provided by alloc_pages_range()) and insure that all drivers use that call. In that case the arches alloc_dma_coherent() may need to be modified to call alloc_pages_range() instead of relying on GFP_DMA.

* [MIPS] SMTC: Instant IPI replay.Ralf Baechle2007-01-231-0/+14
| | | | | | | | | | | | SMTC pseudo-interrupts between TCs are deferred and queued if the target TC is interrupt-inhibited (IXMT). In the first SMTC prototypes, these queued IPIs were serviced on return to user mode, or on entry into the kernel idle loop. The INSTANT_REPLAY option dispatches them as part of local_irq_restore() processing, which adds runtime overhead (hence the option to turn it off), but ensures that IPIs are handled promptly even under heavy I/O interrupt load.

* [PATCH] LOG2: Implement a general integer log2 facility in the kernelDavid Howells2006-12-081-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This facility provides three entry points: ilog2() Log base 2 of unsigned long ilog2_u32() Log base 2 of u32 ilog2_u64() Log base 2 of u64 These facilities can either be used inside functions on dynamic data: int do_something(long q) { ...; y = ilog2(x) ...; } Or can be used to statically initialise global variables with constant values: unsigned n = ilog2(27); When performing static initialisation, the compiler will report "error: initializer element is not constant" if asked to take a log of zero or of something not reducible to a constant. They treat negative numbers as unsigned. When not dealing with a constant, they fall back to using fls() which permits them to use arch-specific log calculation instructions - such as BSR on x86/x86_64 or SCAN on FRV - if available.

* [MIPS] Compile __do_IRQ() when really neededFranck Bui-Huu2006-12-061-0/+9
| | | | | | | | | | | | | | | | | __do_IRQ() is needed only by irq handlers that can't use default handlers defined in kernel/irq/chip.c. For others platforms there's no need to compile this function since it won't be used. For those platforms this patch defines GENERIC_HARDIRQS_NO__DO_IRQ symbol which is used exactly for this purpose. Futhermore for platforms which do not use __do_IRQ(), end() method which is part of the 'irq_chip' structure is not used. This patch simply removes this method in this case.
