sh: fix miscompilation of ip_fast_csum with gcc >= 4.3

2008-06-02T03:40:14Z

As noted by Matthew Wilcox: Kyle McMartin just tracked down a bug on parisc to a missing "memory" clobber in the inline assembly implementation of ip_fast_csum. The FRV, SH and Xtensa ports are also missing a memory clobber, so I thought it would be polite to let you know. The bug manifests as dropped network packets (obviously they have the wrong checksum). It started appearing for parisc with GCC 4.3. The GCC manual says: If your assembler instructions access memory in an unpredictable fashion, add `memory' to the list of clobbered registers. This will cause GCC to not keep memory values cached in registers across the assembler instruction and not optimize stores or loads to that memory. I see that FRV has a 400 byte memory output which may prevent this problem from appearing, but SH and Xtensa have nothing to prevent this bug. Hope this saves you a few days of debugging.

sh: Fix DMAC base address for SH7709S

2008-05-09T10:04:12Z

On SH7709S, DMAC can be found at 0xa4000020 (as with most of the other sh3 cpu subtypes). Split out definition of DMAC base address from definitions of DMTE irqs. Signed-off-by: Steve Glendinning Signed-off-by: Paul Mundt

sh: add interrupt ack code to sh3

2008-05-08T10:52:03Z

This patch adds interrupt acknowledge code for external interrupt sources on sh3 processors. Only really required for edge triggered interrupts, but we ack regardless of sense configuration. Signed-off-by: Magnus Damm Signed-off-by: Paul Mundt

sh: unify external irq pin code for sh3

2008-05-08T10:52:00Z

This patch unifies the sh3 external irq pin code. It buys us some savings with reduced code redundancy, but the main feature with this change is irq sense selection support for all sh3 processors. Signed-off-by: Magnus Damm Signed-off-by: Paul Mundt

sh: add memory resources to /proc/iomem

2008-05-08T10:51:51Z

Add physical memory resources such as System RAM, Kernel code/data/bss and reserved crash dump area to /proc/iomem. Same strategy as on x86. Signed-off-by: Magnus Damm Signed-off-by: Paul Mundt

sh: remove the broken SH_MPC1211 support

2008-05-08T10:51:39Z

SH_MPC1211 has been marked as BROKEN for some time. Unless someone is working on reviving it now, I'd therefore suggest this patch to remove it. Signed-off-by: Adrian Bunk Signed-off-by: Paul Mundt
