xtensa: add SMP support

2014-01-14T18:19:58+00:00

This is largely based on SMP code from the xtensa-2.6.29-smp tree by Piet Delaney, Marc Gauthier, Joe Taylor, Christian Zankel (and possibly other Tensilica folks). Signed-off-by: Max Filippov Signed-off-by: Chris Zankel

xtensa: add support for TLS

2013-02-24T03:35:57+00:00

The Xtensa architecture provides a global register called THREADPTR for the purpose of Thread Local Storage (TLS) support. This allows us to use a fairly simple implementation, keeping the thread pointer in the regset and simply saving and restoring it upon entering/exiting the from user space.

Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/signal

2012-12-21T02:05:28+00:00

Pull signal handling cleanups from Al Viro: "sigaltstack infrastructure + conversion for x86, alpha and um, COMPAT_SYSCALL_DEFINE infrastructure. Note that there are several conflicts between "unify SS_ONSTACK/SS_DISABLE definitions" and UAPI patches in mainline; resolution is trivial - just remove definitions of SS_ONSTACK and SS_DISABLED from arch/*/uapi/asm/signal.h; they are all identical and include/uapi/linux/signal.h contains the unified variant." Fixed up conflicts as per Al. * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/signal: alpha: switch to generic sigaltstack new helpers: __save_altstack/__compat_save_altstack, switch x86 and um to those generic compat_sys_sigaltstack() introduce generic sys_sigaltstack(), switch x86 and um to it new helper: compat_user_stack_pointer() new helper: restore_altstack() unify SS_ONSTACK/SS_DISABLE definitions new helper: current_user_stack_pointer() missing user_stack_pointer() instances Bury the conditionals from kernel_thread/kernel_execve series COMPAT_SYSCALL_DEFINE: infrastructure

missing user_stack_pointer() instances

2012-12-19T23:07:39+00:00

for the architectures that have usp in pt_regs and do not have user_stack_pointer() already defined. Signed-off-by: Al Viro

xtensa: clean up files to make them code-style compliant

2012-12-19T05:10:25+00:00

Remove heading and trailing spaces, trim trailing lines, and wrap lines that are longer than 80 characters. Signed-off-by: Chris Zankel

xtensa: save and restore scompare1 SR on kernel entry

2012-12-19T05:10:22+00:00

Although scompare1 may be saved/restored by xchal_ncp_{load,store} macros, explicit save/restore of registers manipulated by the kernel itself is considered more correct. Signed-off-by: Max Filippov Signed-off-by: Chris Zankel

UAPI: (Scripted) Disintegrate arch/xtensa/include/asm

ptrace: unify show_regs() prototype

[ poleg@redhat.com: no need to declare show_regs() in ptrace.h, sched.h does this ] Signed-off-by: Mike Frysinger Cc: Tejun Heo Signed-off-by: Oleg Nesterov Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

xtensa: Shuffle include statements to fix linker script

2010-05-02T08:05:13+00:00

The linker script was including assembly macros from the coprocessor header file that is not otherwise used by the script. Signed-off-by: Chris Zankel

xtensa: use generic ptrace_resume code

2010-03-12T23:52:39+00:00

Use the generic ptrace_resume code for PTRACE_SYSCALL, PTRACE_CONT, PTRACE_KILL and PTRACE_SINGLESTEP. This implies defining arch_has_single_step in and implementing the user_enable_single_step and user_disable_single_step functions, which also causes the breakpoint information to be cleared on fork, which could be considered a bug fix. Also the TIF_SYSCALL_TRACE thread flag is now cleared on PTRACE_KILL which it previously wasn't which is consistent with all architectures using the modern ptrace code.
