High resolution timer support. Implemented for x86 CPUs using TSC. Extracted generic grub_millisleep() so it's linked in only as needed. This requires a Pentium compatible CPU; if the RDTSC instruction is not supported, then it falls back on the generic grub_get_time_ms() implementation that uses the machine's RTC. * conf/i386-pc.rmk (kernel_img_SOURCES): Add `kern/time.c', `kern/i386/tsc.c', `kern/generic/rtc_get_time_ms.c' and `kern/generic/millisleep.c'. * conf/i386-efi.rmk (kernel_mod_SOURCES): Add `kern/i386/tsc.c', `kern/generic/rtc_get_time_ms.c' and `kern/generic/millisleep.c'. * conf/x86_64-efi.rml (kernel_mod_SOURCES): Add `kern/generic/millisleep.c' and `kern/generic/rtc_get_time_ms.c'. * conf/sparc64-ieee1275.rmk (kernel_elf_SOURCES): Likewise. * conf/powerpc-ieee1275.rmk (kernel_elf_SOURCES): Add `kern/generic/millisleep.c'. * conf/i386-ieee1275.rmk (kernel_elf_SOURCES): Likewise. * conf/i386-coreboot.rmk (kernel_elf_SOURCES): Add `kern/time.c'. * kern/generic/rtc_get_time_ms.c: New file. * kern/generic/millisleep.c: New file. * kern/misc.c: Don't include <kern/time.h> anymore. (grub_millisleep_generic): Removed. * commands/sleep.c (grub_interruptible_millisleep): Uses grub_get_time_ms() instead of grub_get_rtc(). * include/grub/i386/tsc.h (grub_get_tsc): New file. New inline function. (grub_cpu_is_cpuid_supported): New inline function. (grub_cpu_is_tsc_supported): New inline function. (grub_tsc_init): New function prototype. (grub_tsc_get_time_ms): New function prototype. * kern/i386/tsc.c (grub_get_time_ms): New file. * include/grub/time.h: Include <grub/types.h. (grub_millisleep_generic): Removed. (grub_get_time_ms): New prototype. (grub_install_get_time_ms): New prototype. (grub_rtc_get_time_ms): New prototype. * kern/time.c (grub_get_time_ms): New function. (grub_install_get_time_ms): New function. * kern/i386/efi/init.c: Include <grub/cpu/tsc.h>. Don't include <grub/time.h> anymore. (grub_millisleep): Removed. (grub_machine_init): Call grub_tsc_init. * kern/i386/linuxbios/init.c (grub_machine_init): Install the RTC get_time_ms() implementation. * kern/sparc64/ieee1275/init.c (grub_millisleep): Removed. (ieee1275_get_time_ms): New function. (grub_machine_init): Install get_time_ms() implementation. * kern/i386/pc/init.c: Include <grub/cpu/tsc.h>. (grub_machine_init): Call grub_tsc_init(). (grub_millisleep): Removed. * kern/ieee1275/init.c (grub_millisleep): Removed. (grub_machine_init): Install ieee1275_get_time_ms() implementation. (ieee1275_get_time_ms): New function. (grub_get_rtc): Now calls ieee1275_get_time_ms(), which does the real work. |
