xtensa: ISS: improve simcall assembly

2020-02-05T05:57:05Z

Drop redundant result moving from inline assembly, use a1 and b1 values as return value and errno value respectively. Signed-off-by: Max Filippov

xtensa: ISS: avoid struct timeval

2019-12-18T17:07:31Z

'struct timeval' will get removed from the kernel, change the one user in arch/xtensa to avoid referencing it, by using a fixed-length array instead. Acked-by: Max Filippov Signed-off-by: Arnd Bergmann

xtensa: drop unneeded platform/hardware.h headers

2018-08-20T19:28:04Z

platform/hardware.h no longer supply any information for processor.h, vectors.h, setup.c or vmlinux.lds.S, don't include it. This header is now empty in the platforms/iss, so remove it altogether. Signed-off-by: Max Filippov

xtensa: rework {CONFIG,PLATFORM}_DEFAULT_MEM_START

2018-08-20T19:28:03Z

Drop PLATFORM_DEFAULT_MEM_START from the platform/hardware.h headers. Provide definition of CONFIG_DEFAULT_MEM_START always, allow changing it only in noMMU configurations when PLATFORM_WANT_DEFAULT_MEM is selected. Change prompt and description so that it's clear that it controls PAGE_OFFSET and PHYS_OFFSET. Signed-off-by: Max Filippov

xtensa: drop unused {CONFIG,PLATFORM}_DEFAULT_MEM_SIZE

2018-08-20T19:27:52Z

Now that noMMU cache attributes are set up separately drop no longer used macro PLATFORM_DEFAULT_MEM_SIZE and config symbol CONFIG_DEFAULT_MEM_SIZE used for setting it. Signed-off-by: Max Filippov

xtensa: ISS: add argc/argv simcall definitions

2017-03-13T20:47:12Z

There are three simcalls implemented by ISS and QEMU related to argc/argv processing: SYS_iss_argc (get number of command line arguments), SYS_iss_argv_size (get size of command line argument block) and SYS_iss_set_argv (copy command line arguments to virtual guest address). Add definitions for these calls to iss/include/platform/simcall.h Signed-off-by: Max Filippov

xtensa: ISS: define simc_exit and use it instead of inline asm

2016-09-21T01:53:00Z

A number of ISS platform functions use inline assembly to invoke simulator exit, not all correctly. Define simc_exit(exit_code) and use it instead of inline assembly. Signed-off-by: Max Filippov

xtensa: don't use a7 in simcalls

2013-05-09T08:07:10Z

To support FRAME_POINTER avoid using a7 in __simc (none of the existing simcalls needs it). Replace calls to __simc with more specific simc_read, simc_write and simc_lseek calls. Signed-off-by: Max Filippov Signed-off-by: Chris Zankel

xtensa: properly fix missing compiler barrier in simcall
