+This corresponds to the NT syscall NtCreateSemaphore().
+
+Semaphores are one of three types of object to be implemented in this driver,
+the others being mutexes and events.
+
+An NT semaphore contains a 32-bit counter, and is signaled and can be acquired
+when the counter is nonzero. The counter has a maximum value which is specified
+at creation time. The initial value of the semaphore is also specified at
+creation time. There are no restrictions on the maximum and initial value.
+
+Each object is exposed as an file, to which any number of fds may be opened.
+When all fds are closed, the object is deleted.
+
+Objects hold a pointer to the ntsync_device that created them. The device's
+reference count is driven by struct file.

linux-clang/linux6.8-zen/linux6.7-zen/patches/0003-[PATCH_v2_4_31]_ntsync:_Introduce_NTSYNC_IOC_WAIT_ANY..patch

@@ -0,0 +1,360 @@
+This corresponds to part of the functionality of the NT syscall
+NtWaitForMultipleObjects(). Specifically, it implements the behaviour where
+the third argument (wait_any) is TRUE, and it does not handle alertable waits.
+Those features have been split out into separate patches to ease review.
+
+NTSYNC_IOC_WAIT_ANY is a vectored wait function similar to poll(). Unlike
+poll(), it "consumes" objects when they are signaled. For semaphores, this means
+decreasing one from the internal counter. At most one object can be consumed by
+this function.
+
+Up to 64 objects can be waited on at once. As soon as one is signaled, the
+object with the lowest index is consumed, and that index is returned via the
+"index" field.
+
+A timeout is supported. The timeout is passed as a u64 nanosecond value, which
+represents absolute time measured against the MONOTONIC clock. If U64_MAX is
+passed, the ioctl waits indefinitely.
+
+This ioctl validates that all objects belong to the relevant device. This is not
+necessary for any technical reason related to NTSYNC_IOC_WAIT_ANY, but will be
+necessary for NTSYNC_IOC_WAIT_ALL introduced in the following patch.
+
+Wait ioctls need to take a temporary reference to each object being waited on.
+As with the device, the reference count of struct file is used for ntsync_obj.

+This corresponds to the NT syscall NtCreateMutant().
+
+An NT mutex is recursive, with a 32-bit recursion counter. When acquired via
+NtWaitForMultipleObjects(), the recursion counter is incremented by one.
+
+The OS records the thread which acquired it. However, in order to keep this
+driver self-contained, the owning thread ID is managed by user-space, and passed
+as a parameter to all relevant ioctls.
+
+The initial owner and recursion count, if any, are specified when the mutex is
+created.

+This does not correspond to any NT syscall. Rather, when a thread dies, it
+should be called by the NT emulator for each mutex.
+
+NT mutexes are robust (in the pthread sense). When an NT thread dies, any
+mutexes it owned are immediately released. Acquisition of those mutexes by other
+threads will return a special value indicating that the mutex was abandoned,
+like EOWNERDEAD returned from pthread_mutex_lock(), and EOWNERDEAD is indeed
+used here for that purpose.

+An NT event holds a single bit of state denoting whether it is signaled or

+
+There are two types of events: manual-reset and automatic-reset. When an
+automatic-reset event is acquired via a wait function, its state is reset to
+unsignaled. Manual-reset events are not affected by wait functions.
+
+Whether the event is manual-reset, and its initial state, are specified at

+NT waits can optionally be made "alertable". This is a special channel for
+thread wakeup that is mildly similar to SIGIO. A thread has an internal single
+bit of "alerted" state, and if a thread is made alerted while an alertable wait,
+the wait will return a special value, consume the "alerted" state, and will not
+consume any of its objects.
+
+Alerts are implemented using events; the user-space NT emulator is expected to
+create an internal ntsync event for each thread and pass that event to wait
+functions.

@@ -0,0 +1,79 @@
+NtWaitForMultipleObjects() can receive a timeout in two forms, relative or
+absolute. Relative timeouts are unaffected by changes to the system time and do
+not count down while the system suspends; for absolute timeouts the opposite is
+true.
+
+In order to make the interface and implementation simpler, the ntsync driver
+only deals in absolute timeouts. However, we need to be able to emulate both
+behaviours apropos suspension and time adjustment, which is achieved by allowing
+either the MONOTONIC or REALTIME clock to be used.

+Test a more realistic usage pattern, and one with heavy contention, in order to

+This test has several threads in a tight loop acquiring a mutex, modifying some
+shared data, and then releasing the mutex. At the end we check if the data is
+consistent.

+This corresponds to the NT syscall NtCreateSemaphore().
+
+Semaphores are one of three types of object to be implemented in this driver,
+the others being mutexes and events.
+
+An NT semaphore contains a 32-bit counter, and is signaled and can be acquired
+when the counter is nonzero. The counter has a maximum value which is specified
+at creation time. The initial value of the semaphore is also specified at
+creation time. There are no restrictions on the maximum and initial value.
+
+Each object is exposed as an file, to which any number of fds may be opened.
+When all fds are closed, the object is deleted.
+
+Objects hold a pointer to the ntsync_device that created them. The device's
+reference count is driven by struct file.

@@ -0,0 +1,360 @@
+This corresponds to part of the functionality of the NT syscall
+NtWaitForMultipleObjects(). Specifically, it implements the behaviour where
+the third argument (wait_any) is TRUE, and it does not handle alertable waits.
+Those features have been split out into separate patches to ease review.
+
+NTSYNC_IOC_WAIT_ANY is a vectored wait function similar to poll(). Unlike
+poll(), it "consumes" objects when they are signaled. For semaphores, this means
+decreasing one from the internal counter. At most one object can be consumed by
+this function.
+
+Up to 64 objects can be waited on at once. As soon as one is signaled, the
+object with the lowest index is consumed, and that index is returned via the
+"index" field.
+
+A timeout is supported. The timeout is passed as a u64 nanosecond value, which
+represents absolute time measured against the MONOTONIC clock. If U64_MAX is
+passed, the ioctl waits indefinitely.
+
+This ioctl validates that all objects belong to the relevant device. This is not
+necessary for any technical reason related to NTSYNC_IOC_WAIT_ANY, but will be
+necessary for NTSYNC_IOC_WAIT_ALL introduced in the following patch.
+
+Wait ioctls need to take a temporary reference to each object being waited on.
+As with the device, the reference count of struct file is used for ntsync_obj.

+This corresponds to the NT syscall NtCreateMutant().
+
+An NT mutex is recursive, with a 32-bit recursion counter. When acquired via
+NtWaitForMultipleObjects(), the recursion counter is incremented by one.
+
+The OS records the thread which acquired it. However, in order to keep this
+driver self-contained, the owning thread ID is managed by user-space, and passed
+as a parameter to all relevant ioctls.
+
+The initial owner and recursion count, if any, are specified when the mutex is
+created.

+This does not correspond to any NT syscall. Rather, when a thread dies, it
+should be called by the NT emulator for each mutex.
+
+NT mutexes are robust (in the pthread sense). When an NT thread dies, any
+mutexes it owned are immediately released. Acquisition of those mutexes by other
+threads will return a special value indicating that the mutex was abandoned,
+like EOWNERDEAD returned from pthread_mutex_lock(), and EOWNERDEAD is indeed

+NT waits can optionally be made "alertable". This is a special channel for
+thread wakeup that is mildly similar to SIGIO. A thread has an internal single
+bit of "alerted" state, and if a thread is made alerted while an alertable wait,
+the wait will return a special value, consume the "alerted" state, and will not
+consume any of its objects.
+
+Alerts are implemented using events; the user-space NT emulator is expected to
+create an internal ntsync event for each thread and pass that event to wait
+functions.

@@ -0,0 +1,79 @@
+NtWaitForMultipleObjects() can receive a timeout in two forms, relative or
+absolute. Relative timeouts are unaffected by changes to the system time and do
+not count down while the system suspends; for absolute timeouts the opposite is
+true.
+
+In order to make the interface and implementation simpler, the ntsync driver
+only deals in absolute timeouts. However, we need to be able to emulate both
+behaviours apropos suspension and time adjustment, which is achieved by allowing
+either the MONOTONIC or REALTIME clock to be used.

+Test a more realistic usage pattern, and one with heavy contention, in order to

+This test has several threads in a tight loop acquiring a mutex, modifying some

+consistent.

+This corresponds to the NT syscall NtCreateSemaphore().
+
+Semaphores are one of three types of object to be implemented in this driver,
+the others being mutexes and events.
+
+An NT semaphore contains a 32-bit counter, and is signaled and can be acquired
+when the counter is nonzero. The counter has a maximum value which is specified
+at creation time. The initial value of the semaphore is also specified at
+creation time. There are no restrictions on the maximum and initial value.
+
+Each object is exposed as an file, to which any number of fds may be opened.
+When all fds are closed, the object is deleted.
+
+Objects hold a pointer to the ntsync_device that created them. The device's
+reference count is driven by struct file.

@@ -0,0 +1,360 @@
+This corresponds to part of the functionality of the NT syscall
+NtWaitForMultipleObjects(). Specifically, it implements the behaviour where
+the third argument (wait_any) is TRUE, and it does not handle alertable waits.
+Those features have been split out into separate patches to ease review.
+
+NTSYNC_IOC_WAIT_ANY is a vectored wait function similar to poll(). Unlike
+poll(), it "consumes" objects when they are signaled. For semaphores, this means
+decreasing one from the internal counter. At most one object can be consumed by
+this function.
+
+Up to 64 objects can be waited on at once. As soon as one is signaled, the
+object with the lowest index is consumed, and that index is returned via the
+"index" field.
+
+A timeout is supported. The timeout is passed as a u64 nanosecond value, which
+represents absolute time measured against the MONOTONIC clock. If U64_MAX is
+passed, the ioctl waits indefinitely.
+
+This ioctl validates that all objects belong to the relevant device. This is not
+necessary for any technical reason related to NTSYNC_IOC_WAIT_ANY, but will be
+necessary for NTSYNC_IOC_WAIT_ALL introduced in the following patch.
+
+Wait ioctls need to take a temporary reference to each object being waited on.
+As with the device, the reference count of struct file is used for ntsync_obj.

+This corresponds to the NT syscall NtCreateMutant().
+
+An NT mutex is recursive, with a 32-bit recursion counter. When acquired via
+NtWaitForMultipleObjects(), the recursion counter is incremented by one.
+
+The OS records the thread which acquired it. However, in order to keep this
+driver self-contained, the owning thread ID is managed by user-space, and passed
+as a parameter to all relevant ioctls.
+
+The initial owner and recursion count, if any, are specified when the mutex is
+created.

+NT mutexes are robust (in the pthread sense). When an NT thread dies, any
+mutexes it owned are immediately released. Acquisition of those mutexes by other
+threads will return a special value indicating that the mutex was abandoned,
+like EOWNERDEAD returned from pthread_mutex_lock(), and EOWNERDEAD is indeed

+bit of "alerted" state, and if a thread is made alerted while an alertable wait,
+the wait will return a special value, consume the "alerted" state, and will not
+consume any of its objects.
+
+Alerts are implemented using events; the user-space NT emulator is expected to
+create an internal ntsync event for each thread and pass that event to wait
+functions.

@@ -0,0 +1,79 @@
+NtWaitForMultipleObjects() can receive a timeout in two forms, relative or
+absolute. Relative timeouts are unaffected by changes to the system time and do
+not count down while the system suspends; for absolute timeouts the opposite is
+true.
+
+In order to make the interface and implementation simpler, the ntsync driver
+only deals in absolute timeouts. However, we need to be able to emulate both
+behaviours apropos suspension and time adjustment, which is achieved by allowing
+either the MONOTONIC or REALTIME clock to be used.
