xtensa: add asm-prototypes.h

2023-06-13T02:48:57Z

Move assembly source prototypes from xtensa_ksyms.c to asm/asm-prototypes.h, move corresponding EXPORT_SYMBOLs to the assembly sources and enable HAVE_ASM_MODVERSIONS for xtensa. Signed-off-by: Max Filippov

xtensa: abstract 'entry' and 'retw' in assembly code

2019-07-08T17:04:48Z

Provide abi_entry, abi_entry_default, abi_ret and abi_ret_default macros that allocate aligned stack frame in windowed and call0 ABIs. Provide XTENSA_SPILL_STACK_RESERVE macro that specifies required stack frame size when register spilling is involved. Replace all uses of 'entry' and 'retw' with the above macros. This makes most of the xtensa assembly code ready for XEA3 and call0 ABI. Signed-off-by: Max Filippov

xtensa: replace variant/core.h with asm/core.h

2019-05-07T00:48:55Z

Introduce the header arch/xtensa/include/asm/core.h that provides definitions for XCHAL macros missing in older xtensa releases. Use this header instead of variant/core.h Signed-off-by: Max Filippov

xtensa: clean up functions in assembly code

2017-12-10T22:48:54Z

Use ENTRY and ENDPROC throughout arch/xtensa/lib assembly sources. Introduce asm/linkage.h and define xtensa-specific __ALIGN macro there. Signed-off-by: Max Filippov

xtensa: clean up fixups in assembly code

2017-12-10T22:48:53Z

Remove duplicate definitions of EX() and similar TRY/CATCH and SRC/DST macros from assembly sources and put single definition into asm/asmmacro.h Signed-off-by: Max Filippov

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

2012-12-19T05:10:25Z

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

xtensa: move headers files to arch/xtensa/include

2008-11-06T18:25:09Z

Move all header files for xtensa to arch/xtensa/include and platform and variant header files to the appropriate arch/xtensa/platforms/ and arch/xtensa/variants/ directories. Moving the files gets also rid of all uses of symlinks in the Makefile. This has been completed already for the majority of the architectures and xtensa is one out of six missing.

[XTENSA] fix sources using deprecated assembler directive

2007-06-01T00:44:31Z

The assembler directive '.begin literal' is deprecated in the newer versions of the binutils (strncopy_user.S and strnlen_user.S). Signed-off-by: Chris Zankel

[PATCH] xtensa: remove extra header files

2006-12-10T17:55:39Z

The Xtensa port contained many header files that were never needed. This rather lengthy patch removes all those files. Unfortunately, there were many dependencies that needed to be updated, so this patch touches quite a few source files.

[PATCH] xtensa: Architecture support for Tensilica Xtensa Part 4

2005-06-24T07:05:21Z

The attached patches provides part 4 of an architecture implementation for the Tensilica Xtensa CPU series. Signed-off-by: Chris Zankel Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
