There is a sysctl option to change that as a transition period, but it will eventually disappear. - -The RDTIME instruction is another less accurate alternative, however its frequency varies from board to board, and there is currently now way to get its frequency from userland [2]. - -Therefore this patch just removes the code for unscaledcycleclock on RISC-V. Without processor specific implementation, abseil relies on std::chrono::steady_clock::now().time_since_epoch() which is basically a wrapper around clock_gettime (CLOCK_MONOTONIC), which in turns use __vdso_clock_gettime(). On RISC-V this VDSO is just a wrapper around RDTIME correctly scaled to use nanoseconds units. - -This fixes the testsuite on riscv64, tested on a VisionFive 2 board. - -[1] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=cc4c07c89aada16229084eeb93895c95b7eabaa3 -[2] https://github.com/abseil/abseil-cpp/pull/1631 -Merge 43356a2548cfde76e164d446cb69004b488c6a71 into 76f8011beabdaee872b5fde7546e02407b220cb1 - -Merging this change closes #1644 - -COPYBARA_INTEGRATE_REVIEW=https://github.com/abseil/abseil-cpp/pull/1644 from aurel32:rv64-no-unscaledcycleclock 43356a2548cfde76e164d446cb69004b488c6a71 -PiperOrigin-RevId: 618286262 -Change-Id: Ie4120a727e7d0bb185df6e06ea145c780ebe6652 - -Upstream-Status: Backport [https://github.com/abseil/abseil-cpp/commit/7335a36d] -[Adapted to apply on top of meta-oe's patch stack] -Signed-off-by: Scott Murray <scott.murray@konsulko.com> ---- - .../absl/base/internal/unscaledcycleclock.cc | 12 ------------ - .../absl/base/internal/unscaledcycleclock_config.h | 5 ++--- - 2 files changed, 2 insertions(+), 15 deletions(-) - -diff --git a/third_party/abseil-cpp/absl/base/internal/unscaledcycleclock.cc b/third_party/abseil-cpp/absl/base/internal/unscaledcycleclock.cc -index f11fecb..103b4f6 100644 ---- a/third_party/abseil-cpp/absl/base/internal/unscaledcycleclock.cc -+++ b/third_party/abseil-cpp/absl/base/internal/unscaledcycleclock.cc -@@ -121,18 +121,6 @@ double UnscaledCycleClock::Frequency() { - return aarch64_timer_frequency; - } - --#elif defined(__riscv) -- --int64_t UnscaledCycleClock::Now() { -- int64_t virtual_timer_value; -- asm volatile("rdcycle %0" : "=r"(virtual_timer_value)); -- return virtual_timer_value; --} -- --double UnscaledCycleClock::Frequency() { -- return base_internal::NominalCPUFrequency(); --} -- - #elif defined(_M_IX86) || defined(_M_X64) - - #pragma intrinsic(__rdtsc) -diff --git a/third_party/abseil-cpp/absl/base/internal/unscaledcycleclock_config.h b/third_party/abseil-cpp/absl/base/internal/unscaledcycleclock_config.h -index 5e232c1..83552fc 100644 ---- a/third_party/abseil-cpp/absl/base/internal/unscaledcycleclock_config.h -+++ b/third_party/abseil-cpp/absl/base/internal/unscaledcycleclock_config.h -@@ -22,7 +22,6 @@ - // The following platforms have an implementation of a hardware counter. - #if defined(__i386__) || defined(__x86_64__) || defined(__aarch64__) || \ - ((defined(__powerpc__) || defined(__ppc__)) && defined(__GLIBC__)) || \ -- defined(__riscv) || \ - defined(_M_IX86) || (defined(_M_X64) && !defined(_M_ARM64EC)) - #define ABSL_HAVE_UNSCALED_CYCLECLOCK_IMPLEMENTATION 1 - #else -@@ -54,8 +53,8 @@ - #if ABSL_USE_UNSCALED_CYCLECLOCK - // This macro can be used to test if UnscaledCycleClock::Frequency() - // is NominalCPUFrequency() on a particular platform. --#if (defined(__i386__) || defined(__x86_64__) || defined(__riscv) || \ -- defined(_M_IX86) || defined(_M_X64)) -+#if (defined(__i386__) || defined(__x86_64__) || defined(_M_IX86) || \ -+ defined(_M_X64)) - #define ABSL_INTERNAL_UNSCALED_CYCLECLOCK_FREQUENCY_IS_CPU_FREQUENCY - #endif - #endif --- -2.44.0 - |
