[ARM] 3665/1: crunch: add ptrace support

2006-06-28T16:55:00Z

Patch from Lennert Buytenhek This patch makes it possible to get/set a task's Crunch state via the ptrace(2) system call. Signed-off-by: Lennert Buytenhek Signed-off-by: Russell King

[ARM] iwmmxt thread state alignment

2006-03-12T22:36:06Z

This patch removes the reliance of iwmmxt on hand coded alignments. Since thread_info is always 8K aligned, specifying that fpstate is 8-byte aligned achieves the same effect without needing to resort to hand coded alignments. Signed-off-by: Russell King

[ARM] 3262/4: allow ptraced syscalls to be overriden

2006-01-14T19:30:04Z

Patch from Nicolas Pitre This is needed by strace to properly handle the tracing of some system calls. It could be useful for other applications as well. Based on an earlier patch from Daniel Jacobowitz. Signed-off-by: Nicolas Pitre Signed-off-by: Daniel Jacobowitz Signed-off-by: Russell King

[ARM] 3200/1: Singlestep over ARM BX and BLX instructions using ptrace fix

2005-12-10T11:59:15Z

Patch from Nikola Valerjev Single stepping an application using ptrace() fails over ARM instructions BX and BLX. Steps to reproduce: Compile and link the following files main.c ----- void foo(); int main() { foo(); return 0; } foo.s ----- .text .globl foo foo: BX LR Using ptrace() functionality, run to main(), and start singlestepping. Singlestep over \"BX LR\" instruction won\'t transfer the control back to main, but run the code to completion. This problems seems to be in the function get_branch_address() in arch/arm/kernel/ptrace.c. The function doesn\'t seem to recognize BX and BLX instructions as branches. BX and BLX instructions can be used to convert from ARM to Thumb mode if the target address has the low bit set. However, they are also perfectly legal in the ARM only mode. Although other things in the kernel seem to indicate that only ARM mode is accepted (and not Thumb), many compilers will generate BX and BLX instructions even when generating ARM only code.

[PATCH] consolidate sys_ptrace()

2005-11-07T15:53:42Z

The sys_ptrace boilerplate code (everything outside the big switch statement for the arch-specific requests) is shared by most architectures. This patch moves it to kernel/ptrace.c and leaves the arch-specific code as arch_ptrace. Some architectures have a too different ptrace so we have to exclude them. They continue to keep their implementations. For sh64 I had to add a sh64_ptrace wrapper because it does some initialization on the first call. For um I removed an ifdefed SUBARCH_PTRACE_SPECIAL block, but SUBARCH_PTRACE_SPECIAL isn't defined anywhere in the tree.
