From afa39105d8e09e5bc9ce2053b10a40839ab9fddd Mon Sep 17 00:00:00 2001 From: Subrata Banik Date: Sat, 18 May 2024 12:26:40 +0000 Subject: libpayload: Add x86_64 (64-bit) support This patch introduces x86_64 (64-bit) support to the payload, building upon the existing x86 (32-bit) architecture. Files necessary for 64-bit compilation are now guarded by the `CONFIG_LP_ARCH_X86_64` Kconfig option. BUG=b:242829490 TEST=Able to verify all valid combinations between coreboot and payload with this patch. Payload Entry Point Behavior with below code. +----------------+--------------------+----------------------------+ | LP_ARCH_X86_64 | Payload Entry Mode | Description | +----------------+--------------------+----------------------------+ | No | 32-bit | Direct protected mode init | +----------------+--------------------+----------------------------+ | Yes | 32-bit | Protected to long mode | +----------------+--------------------+----------------------------+ | Yes | 64-bit | Long mode initialization | +----------------+--------------------+----------------------------+ Change-Id: I69fda47bedf1a14807b1515c4aed6e3a1d5b8585 Signed-off-by: Subrata Banik Reviewed-on: https://review.coreboot.org/c/coreboot/+/81968 Reviewed-by: Julius Werner Tested-by: build bot (Jenkins) --- payloads/libpayload/libc/Makefile.mk | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'payloads/libpayload/libc/Makefile.mk') diff --git a/payloads/libpayload/libc/Makefile.mk b/payloads/libpayload/libc/Makefile.mk index 2840476619..c9fc17a7b5 100644 --- a/payloads/libpayload/libc/Makefile.mk +++ b/payloads/libpayload/libc/Makefile.mk @@ -29,7 +29,7 @@ libc-$(CONFIG_LP_LIBC) += malloc.c printf.c console.c string.c libc-$(CONFIG_LP_LIBC) += memory.c ctype.c lib.c libgcc.c -libc-$(CONFIG_LP_LIBC) += rand.c time.c exec.c +libc-$(CONFIG_LP_LIBC) += rand.c time.c libc-$(CONFIG_LP_LIBC) += readline.c getopt_long.c sysinfo.c libc-$(CONFIG_LP_LIBC) += args.c libc-$(CONFIG_LP_LIBC) += strlcpy.c -- cgit v1.2.3
