| | | | | | | | | | | | | | far more convenient for libkvm to work with because of the page table block at the beginning. As a result, the MD code is smaller. libkvm will automatically detect old vs mini dumps on i386 and amd64. libkvm will handle i386 PAE and non-PAE modes. There is a PAE flag in the i386 minidump header to signal the width of the entries in the page table block. Other convenient values are also present, such as kernbase and the direct map addresses on amd64.

| | | | | | | | | | | | | | | | | | | | | returned an lseek offset in a "u_long *" value, which can't express >4GB offsets on 32 bit machines (eg: PAE). Change to "off_t *" for all. Support ELF crashdumps on i386 and amd64. Support PAE crashdumps on i386. This is done by auto-detecting the presence of the IdlePDPT which means that PAE is active. I used Marcel's _kvm_pa2off strategy and ELF header reader for ELF support on amd64. Paul Saab ported the amd64 changes to i386 and we implemented the PAE support from there. Note that gdb6 in the src tree uses whatever libkvm supports. If you want to debug an old crash dump, you might want to keep an old libkvm.so handy and use LD_PRELOAD or the like. This does not detect the old raw dump format. Approved by: re

* Refactor a bunch of scheduler code to give basically the same behaviourjulian2004-09-051-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | but with slightly cleaned up interfaces. The KSE structure has become the same as the "per thread scheduler private data" structure. In order to not make the diffs too great one is #defined as the other at this time. The KSE (or td_sched) structure is now allocated per thread and has no allocation code of its own. Concurrency for a KSEGRP is now kept track of via a simple pair of counters rather than using KSE structures as tokens. Since the KSE structure is different in each scheduler, kern_switch.c is now included at the end of each scheduler. Nothing outside the scheduler knows the contents of the KSE (aka td_sched) structure. The fields in the ksegrp structure that are to do with the scheduler's queueing mechanisms are now moved to the kg_sched structure. (per ksegrp scheduler private data structure). In other words how the scheduler queues and keeps track of threads is no-one's business except the scheduler's. This should allow people to write experimental schedulers with completely different internal structuring. A scheduler call sched_set_concurrency(kg, N) has been added that notifies teh scheduler that no more than N threads from that ksegrp should be allowed to be on concurrently scheduled. This is also used to enforce 'fainess' at this time so that a ksegrp with 10000 threads can not swamp a the run queue and force out a process with 1 thread, since the current code will not set the concurrency above NCPU, and both schedulers will not allow more than that many onto the system run queue at a time. Each scheduler should eventualy develop their own methods to do this now that they are effectively separated. Rejig libthr's kernel interface to follow the same code paths as linkse for scope system threads. This has slightly hurt libthr's performance but I will work to recover as much of it as I can. Thread exit code has been cleaned up greatly. exit and exec code now transitions a process back to 'standard non-threaded mode' before taking the next step.
