From: Xi Ruoyao Date: Wed, 1 Apr 2026 13:53:12 +0000 (+0800) Subject: ACPI: tables: Enable FPDT on LoongArch X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=1b7cbe343349ec5aec6f3140820180c5bc00b14f;p=thirdparty%2Fkernel%2Flinux.git ACPI: tables: Enable FPDT on LoongArch FPDT provides system- and application-readable performance statistics, useful for profiling and analyzing boot-time performance. FPDT table support is now available as a pending patch at the EDK II upstream [1] and has been tested on real hardware such as Loongson XA61200_V1.1 and XB612B0_V1.2 with patched firmware. We have also cross checked systemd-analyze(1) against a stop watch and the `dp' command in EFI Shell to see that the timing information are correct. Now that the functionality of FPDT is verified on LoongArch hardware, list LOONGARCH as a possible dependency, allowing it to be enabled.
