Add a test that validates the residency over a s2idle cycle is within the threshold. v2: skip d3cold disable for igfx (Anshuman) Signed-off-by: Riana Tauro --- tests/xe/xe_pm_residency.c | 56 ++++++++++++++++++++++++++++++++++---- 1 file changed, 51 insertions(+), 5 deletions(-) diff --git a/tests/xe/xe_pm_residency.c b/tests/xe/xe_pm_residency.c index 4936de166..78d820aee 100644 --- a/tests/xe/xe_pm_residency.c +++ b/tests/xe/xe_pm_residency.c @@ -10,8 +10,10 @@ * Functionality: GT C States * Test category: functionality test */ +#include #include "igt.h" +#include "igt_device.h" #include "igt_sysfs.h" #include "xe/xe_query.h" @@ -29,6 +31,11 @@ const double tolerance = 0.1; (tol) * 100.0, (tol) * 100.0, \ (double)(ref)) +enum test_type { + TEST_S2IDLE, + TEST_SLEEP, +}; + /** * SUBTEST: gt-c6-on-idle * Description: Validate GT C6 state on idle @@ -38,9 +45,22 @@ const double tolerance = 0.1; * Description: basic residency test to validate idle residency * measured over a time interval is within the tolerance * Run type: FULL + * + * SUBTEST: gt-c6-freeze + * Description: Validate idle residency measured over suspend(s2idle) + * is within the tolerance + * Run type: FULL */ IGT_TEST_DESCRIPTION("Tests for gtidle properties"); +static unsigned long walltime_ms(void) +{ + struct timespec ts; + + clock_gettime(CLOCK_REALTIME, &ts); + return ts.tv_sec * 1000 + ts.tv_nsec / 1000000; +} + static unsigned int measured_usleep(unsigned int usec) { struct timespec ts = { }; @@ -69,15 +89,25 @@ static unsigned long read_idle_residency(int fd, int gt) return residency; } -static void test_idle_residency(int fd, int gt) +static void test_idle_residency(int fd, int gt, enum test_type flag) { unsigned long elapsed_ms, residency_start, residency_end; igt_assert_f(igt_wait(xe_is_gt_in_c6(fd, gt), 1000, 1), "GT not in C6\n"); - residency_start = read_idle_residency(fd, gt); - elapsed_ms = measured_usleep(SLEEP_DURATION * 1000) / 1000; - residency_end = read_idle_residency(fd, gt); + if (flag == TEST_S2IDLE) { + residency_start = read_idle_residency(fd, gt); + elapsed_ms -= walltime_ms(); + igt_system_suspend_autoresume(SUSPEND_STATE_FREEZE, SUSPEND_TEST_NONE); + elapsed_ms += walltime_ms(); + residency_end = read_idle_residency(fd, gt); + } + + if (flag == TEST_SLEEP) { + residency_start = read_idle_residency(fd, gt); + elapsed_ms = measured_usleep(SLEEP_DURATION * 1000) / 1000; + residency_end = read_idle_residency(fd, gt); + } igt_info("Measured %lums of idle residency in %lums\n", residency_end - residency_start, elapsed_ms); @@ -88,6 +118,8 @@ static void test_idle_residency(int fd, int gt) igt_main { int fd, gt; + char pci_slot_name[NAME_MAX]; + uint32_t d3cold_allowed; igt_fixture { fd = drm_open_driver(DRIVER_XE); @@ -99,10 +131,24 @@ igt_main xe_for_each_gt(fd, gt) igt_assert_f(igt_wait(xe_is_gt_in_c6(fd, gt), 1000, 1), "GT not in C6\n"); + igt_describe("Validate idle residency measured over suspend cycle is within the tolerance"); + igt_subtest("gt-c6-freeze") { + if (xe_has_vram(fd)) { + igt_device_get_pci_slot_name(fd, pci_slot_name); + igt_pm_get_d3cold_allowed(pci_slot_name, &d3cold_allowed); + igt_pm_set_d3cold_allowed(pci_slot_name, 0); + } + xe_for_each_gt(fd, gt) + test_idle_residency(fd, gt, TEST_S2IDLE); + + if (xe_has_vram(fd)) + igt_pm_set_d3cold_allowed(pci_slot_name, d3cold_allowed); + } + igt_describe("Validate idle residency measured over a time interval is within the tolerance"); igt_subtest("idle-residency") xe_for_each_gt(fd, gt) - test_idle_residency(fd, gt); + test_idle_residency(fd, gt, TEST_SLEEP); igt_fixture { close(fd); -- 2.40.0
