[RFC PATCH v3 1/2] ntdll/tests: Test updating TickCount in user_shared_data.
by Rémi Bernon April 28, 2020

April 28, 2020

Original patch from: Andrew Wesie <awesie(a)gmail.com> Signed-off-by: Rémi Bernon <rbernon(a)codeweavers.com> --- v3: Server-side implementation of USD timestamp updates. The system time check still has some large diffs compared to native after patch #2, probably because of some different clock granularity between server and client. I didn't include an InterruptTime test because depending on the Windows versions, RtlQueryUnbiasedInterruptTime sometimes doesn't match the USD clock. I'm sending it as RFC as it's still a little bit rough on the edges, and I only tested on Linux so far. dlls/ntdll/tests/time.c | 52 +++++++++++++++++++++++++++++++++++++++++ 1 file changed, 52 insertions(+) diff --git a/dlls/ntdll/tests/time.c b/dlls/ntdll/tests/time.c index 5382a952d8d8..cc6e9f226e63 100644 --- a/dlls/ntdll/tests/time.c +++ b/dlls/ntdll/tests/time.c @@ -18,7 +18,9 @@ * Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301, USA */ +#define NONAMELESSUNION #include "ntdll_test.h" +#include "ddk/wdm.h" #define TICKSPERSEC 10000000 #define TICKSPERMSEC 10000 @@ -29,6 +31,7 @@ static VOID (WINAPI *pRtlTimeFieldsToTime)( PTIME_FIELDS TimeFields, PLARGE_IN static NTSTATUS (WINAPI *pNtQueryPerformanceCounter)( LARGE_INTEGER *counter, LARGE_INTEGER *frequency ); static NTSTATUS (WINAPI *pRtlQueryTimeZoneInformation)( RTL_TIME_ZONE_INFORMATION *); static NTSTATUS (WINAPI *pRtlQueryDynamicTimeZoneInformation)( RTL_DYNAMIC_TIME_ZONE_INFORMATION *); +static ULONG (WINAPI *pNtGetTickCount)(void); static const int MonthLengths[2][12] = { @@ -153,12 +156,60 @@ static void test_RtlQueryTimeZoneInformation(void) wine_dbgstr_w(tzinfo.DaylightName)); } +static ULONG64 read_ksystem_time(volatile KSYSTEM_TIME *time) +{ + ULONG64 high, low; + + do + { + high = time->High1Time; + low = time->LowPart; + } + while (high != time->High2Time); + + return high << 32 | low; +} + +static void test_NtGetTickCount(void) +{ + KSHARED_USER_DATA *user_shared_data = (void *)0x7ffe0000; + ULONG64 usd_time; + ULONG diff; + int i; + + for (i = 0; i < 5; ++i) + { + LARGE_INTEGER system_time; + + if (user_shared_data->NtMajorVersion <= 5 && user_shared_data->NtMinorVersion <= 1) + usd_time = ((ULONG64)user_shared_data->TickCountLowDeprecated * user_shared_data->TickCountMultiplier) >> 24; + else + usd_time = (read_ksystem_time(&user_shared_data->u.TickCount) * user_shared_data->TickCountMultiplier) >> 24; + + if (!pNtGetTickCount) + diff = GetTickCount() - usd_time; + else + diff = pNtGetTickCount() - usd_time; + todo_wine + ok(diff < 100, "NtGetTickCount - USD->TickCount too high, expected < 100 got %d\n", diff); + + usd_time = read_ksystem_time(&user_shared_data->SystemTime); + NtQuerySystemTime(&system_time); + diff = system_time.QuadPart - usd_time; + todo_wine + ok(diff < 100, "NtQuerySystemTime - USD->SystemTime too high, expected < 100 got %d\n", diff); + + Sleep(50); + } +} + START_TEST(time) { HMODULE mod = GetModuleHandleA("ntdll.dll"); pRtlTimeToTimeFields = (void *)GetProcAddress(mod,"RtlTimeToTimeFields"); pRtlTimeFieldsToTime = (void *)GetProcAddress(mod,"RtlTimeFieldsToTime"); pNtQueryPerformanceCounter = (void *)GetProcAddress(mod, "NtQueryPerformanceCounter"); + pNtGetTickCount = (void *)GetProcAddress(mod,"NtGetTickCount"); pRtlQueryTimeZoneInformation = (void *)GetProcAddress(mod, "RtlQueryTimeZoneInformation"); pRtlQueryDynamicTimeZoneInformation = @@ -169,5 +220,6 @@ START_TEST(time) else win_skip("Required time conversion functions are not available\n"); test_NtQueryPerformanceCounter(); + test_NtGetTickCount(); test_RtlQueryTimeZoneInformation(); } -- 2.26.1
