Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

sh: Fixup __cmpxchg() compile breakage with gcc4. As reported by Manuel: When I build linux with GCC-4.x and enable CONFIG_CC_OPTIMIZE_FOR_SIZE linking fails with this error: LD .tmp_vmlinux1 kernel/built-in.o: In function '__cmpxchg_called_with_bad_pointer' make[1]: *** [.tmp_vmlinux1] Error 1 make: *** [_all] Error 2 This ended up being an inlining problem, fixed by explicitly including linux/compiler.h and grabbing the definitions from there.

sh: Add control register barriers. Currently when making changes to control registers, we typically need some time for changes to take effect (8 nops, generally). However, for sh4a we simply need to do an icbi.. This is a simple patch for implementing a general purpose ctrl_barrier() which functions as a control register write barrier. There's some additional documentation in the patch itself, but it's pretty self explanatory. There were also some places where we were not doing the barrier, which didn't seem to have any adverse effects on legacy parts, but certainly did on sh4a. It's safer to have the barrier in place for legacy parts as well in these cases, though this does make flush_tlb_all() more expensive (by an order of 8 nops). We can ifdef around the flush_tlb_all() case for now if it's clear that all legacy parts won't have a problem with this. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

sh: Fix exception_handling_table alignment. With the recent change ripping out interrupt_table, explicit padding of the table was missing, causing bad things to happen when manually inserting handlers in to the table. This problem particularly showed up in relation to do_fpu_state_restore() which was inserted quite deeply in to the table and ended up scribbling over a slab object.

sh: Preparation for uncached jumps through PMB. Presently most of the 29-bit physical parts do P1/P2 segmentation with a 1:1 cached/uncached mapping, jumping between the two to control the caching behaviour. This provides the basic infrastructure to maintain this behaviour on 32-bit physical parts that don't map P1/P2 at all, using a shiny new linker section and corresponding fixmap entry.

sh: trapped io support V2 The idea is that we want to get rid of the in/out/readb/writeb callbacks from the machvec and replace that with simple inline read and write operations to memory. Fast and simple for most hardware devices (think pci). Some devices require special treatment though - like 16-bit only CF devices - so we need to have some method to hook in callbacks. This patch makes it possible to add a per-device trap generating filter. This way we can get maximum performance of sane hardware - which doesn't need this filter - and crappy hardware works but gets punished by a performance hit. V2 changes things around a bit and replaces io access callbacks with a simple minimum_bus_width value. In the future we can add stride as well.
