| | | | | | | | | | | | | | | | | | lock level is 0. Thus far, the threads implementation doesn't use mutexes or condition variables so the lock level should be 0. Save the return value when trying to schedule a new thread and use this to return an error from pthread_create(). Change the max sleep time for an idle KSE to 1 minute from 2 minutes. Maintain a count of the number of KSEs within a KSEG. With these changes scope system threads seem to work, but heavy use of them crash the kernel (supposedly VM bugs).

| | | | | | | | | | | | | | | An incorrectly-sized allocation was being made due to an incorrect argument to the `sizeof' operator. Obvious, because it violated the `foo = malloc(sizeof(*foo))' idiom. Hard-to-see, because it was a missing `*' (`*p' versus `**p').

* Add an i386-specifc hack to always set %gs. There still seemsDaniel Eischen2003-04-2114-366/+580
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | to be instances where the kernel doesn't properly save and/or restore it. Use noupcall and nocompleted flags in the KSE mailbox. These require kernel changes to work which will be committed sometime later. Things still work without the changes. Remove the general kse entry function and use two different functions -- one for scope system threads and one for scope process threads. The scope system function is not yet enabled and we use the same function for all threads at the moment. Keep a copy of the KSE stack for the case that a KSE runs a scope system thread and uses the same stack as the thread (no upcalls are generated, so a separate stack isn't needed). This isn't enabled yet. Use a separate field for the KSE waiting flag. It isn't correct to use the mailbox flags field. The following fixes were provided by David Xu: o Initialize condition variable locks with thread versions of the low-level locking functions instead of the kse versions. o Enable threading before creating the first thread instead of after. o Don't enter critical regions when trying to malloc/free or call functions that malloc/free. o Take the scheduling lock when inheriting thread attributes. o Check the attribute's stack pointer instead of the attributes stack size for null when allocating a thread's stack. o Add a kseg reinit function so we don't have to destroy and then recreate the same lock. o Check the return value of kse_create() and return an appropriate error if it fails. o Don't forget to destroy a thread's locks when freeing it. o Examine the correct flags word for checking to see if a thread is in a synchronization queue. Things should now work on an SMP kernel. Notes: svn path=/head/; revision=113786

* Add support for ia64.Marcel Moolenaar2003-04-202-0/+64
| | | | | | | | | | | | | | Note that the tp register (r13) is reserved as the TLS pointer in the same way that that gp register (r1) is reserved as the global pointer. This implementation uses the tp register to point to the thread structure used by the threads implementation. This is not in violation with the runtime specification provided the TLS is a fixed distance from the thread structure. This is only an issue when code used the __thread keyword to create TLS. This is not supported at the moment. Notes: svn path=/head/; revision=113735

The ability to create more than 1 KSE via pthread_setconcurrency() is in the works as well as support for PTHREAD_SCOPE_SYSTEM threads. Those should come shortly. There are still some known issues which davidxu and I are working on, but it'll make it easier for us by committing what we have. This library now passes all of the ACE tests that libc_r passes with the exception of one. It also seems to work OK with KDE including konqueror, kwrite, etc. I haven't been able to get mozilla to run due to lack of java plugin, so I'd be interested to see how it works with that.
