From 721dfbfe017583914d37ad30aea5d5634070ede2 Mon Sep 17 00:00:00 2001 From: bernard Date: Mon, 12 May 2025 19:29:35 +0800 Subject: [smart] Add vDSO support for RISC-V architecture and refactor related components - Implemented vDSO functionality for the RISC-V architecture, including the necessary source files and linker scripts. - Introduced a new `vdso_sys.c` file for RISC-V, containing functions to handle time retrieval using the vDSO mechanism. - Created architecture-specific linker scripts (`vdso.lds.S`) for both AArch64 and RISC-V. - Updated the build system to support vDSO compilation for RISC-V, including necessary adjustments in `SConstruct` files. - Refactored existing vDSO code to improve compatibility and maintainability across architectures. - Adjusted the maximum number of PTY devices in the terminal configuration from 64 to 32 for better resource management. - Fixed minor issues in existing code, including correcting the path for the vDSO shared library and ensuring proper function definitions. --- components/lwp/SConscript | 3 +++ 1 file changed, 3 insertions(+) (limited to 'components/lwp/SConscript') diff --git a/components/lwp/SConscript b/components/lwp/SConscript index cd8a2428a5..6eb8763fde 100644 --- a/components/lwp/SConscript +++ b/components/lwp/SConscript @@ -25,11 +25,14 @@ if platform in platform_file.keys(): # support platforms if arch in support_arch.keys() and cpu in support_arch[arch]: asm_path = 'arch/' + arch + '/' + cpu + '/*_' + platform_file[platform] arch_common = 'arch/' + arch + '/' + 'common/*.c' + common = 'arch/common/*.c' if not GetDepend('RT_USING_VDSO'): vdso_files = ['vdso_data.c', 'vdso.c'] src += [f for f in Glob(arch_common) if os.path.basename(str(f)) not in vdso_files] + src += [f for f in Glob(common) if os.path.basename(str(f)) not in vdso_files] else: src += Glob(arch_common) + src += Glob(common) if not GetDepend('ARCH_MM_MMU'): excluded_files = ['ioremap.c', 'lwp_futex.c', 'lwp_mm_area.c', 'lwp_pmutex.c', 'lwp_shm.c', 'lwp_user_mm.c'] src += [f for f in Glob('*.c') if os.path.basename(str(f)) not in excluded_files] + Glob(asm_path) -- cgit v1.3.1
