SVN rev 224217 on 2011-07-19 13:00:30Z by attilio Bump MAXCPU for amd64, ia64 and XLP mips appropriately. From now on, default values for FreeBSD will be 64 maxiumum supported CPUs on amd64 and ia64 and 128 for XLP. All the other architectures seem already capped appropriately (with the exception of sparc64 which needs further support on jalapeno flavour). Bump __FreeBSD_version in order to reflect KBI/KPI brekage introduced during the infrastructure cleanup for supporting MAXCPU > 32. This covers cpumask_t retiral too. The switch is considered completed at the present time, so for whatever bug you may experience that is reconducible to that area, please report immediately.

SVN rev 200200 on 2009-12-07 00:54:02Z by marcel Allocate the VHPT for each CPU in cpu_mp_start(), rather than allocating MAXCPU VHPTs up-front. This allows us to max-out MAXCPU without memory waste -- MAXCPU is now 32 for SMP kernels. This change also eliminates the VHPT scaling based in the total memory in the system. It's the workload that determines the best size of the VHPT. The workload can be affected by the amount of memory, but not necessarily. For example, there's no performance difference between VHPT sizes of 256KB, 512KB and 1MB when building the LINT kernel. This was observed with a system that has 8GB of memory. By default the kernel will allocate a 1MB VHPT. The user can tune the system with the "machdep.vhpt.log2size" tunable.

SVN rev 199719 on 2009-11-23 21:09:23Z by marcel Revert previous commit. The problem was not related to overrunning the kernel stack at all. The new USB stack simply caused a change in timing that triggered a firmware bug more often. The addition of PRINTF_BUFR_SIZE apparently triggered the same firmware bug even more reliably. But even with KSTACK_PAGES=5, one instance of the firmware bug remained: booting with a CD inserted. This problem was run into by accident after installing Debian and having to boot FreeBSD to fixup the GPT partitioning (Thanks... not). After bumping KSTACK_PAGES to 5, it was pretty unbelievable that the stack was still being too small. After updating the firmware we could boot with a CD inserted and KSTACK_PAGES could be lowered back to 4 pages without problems. Note: It is believed to be a timing related firmware bug, because the machine check information showed access to the serial console on one CPU and access to the EHCI HCD on the other CPU. Since both are devices on the management unit and thus virtualized in some way, any execution trace that does not include concurrent access to the BMC from both CPUs is fine. Note also that it's not understood exactly how increasing the kernel stack avoided hitting the firmware bug. A change in page faults does change timing, but it's not known if that's what's happening here. In any case: the problem is being monitored. Reverting back to 4 pages for the kernel stack is preferred, because it makes it easier to switch to 16K pages (double the page size) without wasting too much memory by not being able to half the number of pages...

SVN rev 198451 on 2009-10-24 20:28:42Z by marcel A 32KB kernel stack is not quite enough. The new USB stack is a bit more stack hungry as compared to the old one that my RX2660 gets a machine check and spontaneously reboots at the time the USB DVD drive is found and attached to CAM as a mass storage device. This doesn't happen always, but definitely varies per kernel build. Likewise when using a 128-byte printf buffer. The additional 128 bytes that printf needs seems to be enough to have the memory stack and register stack collide and causing a machine check. Thus: Bump KSTACK_PAGES from 4 to 5.

Reduce the default MAXCPU from 16 to 4. This is in preparation of allocating a VHPT per CPU. Since we don't yet know how many CPUs are actually in the system at the time we need to allocate the VHPTs, we allocate for MAXCPU processors. This can result in a lot of wasted space for 2-way machines. So, for now, limit MAXCPU to something smaller until we have something more dynamic.

Migrate the thread stack management functions from the machine-dependent to the machine-independent parts of the VM. At the same time, this introduces vm object locking for the non-i386 platforms. Two details: 1. KSTACK_GUARD has been removed in favor of KSTACK_GUARD_PAGES. The different machine-dependent implementations used various combinations of KSTACK_GUARD and KSTACK_GUARD_PAGES. To disable guard page, set KSTACK_GUARD_PAGES to 0. 2. Remove the (unnecessary) clearing of PG_ZERO in vm_thread_new. In 5.x, (but not 4.x,) PG_ZERO can only be set if VM_ALLOC_ZERO is passed to vm_page_alloc() or vm_page_grab().

Initiate deorbit burn for the i386-only a.out related support. Moves are under way to move the remnants of the a.out toolchain to ports. As the comment in src/Makefile said, this stuff is deprecated and one should not expect this to remain beyond 4.0-REL. It has already lasted WAY beyond that. Notable exceptions: gcc - I have not touched the a.out generation stuff there. ldd/ldconfig - still have some code to interface with a.out rtld. old as/ld/etc - I have not removed these yet, pending their move to ports. some includes - necessary for ldd/ldconfig for now. Tested on: i386 (extensively), alpha

KSE Milestone 2 Note ALL MODULES MUST BE RECOMPILED make the kernel aware that there are smaller units of scheduling than the process. (but only allow one thread per process at this time). This is functionally equivalent to teh previousl -current except that there is a thread associated with each process. Sorry john! (your next MFC will be a doosie!)

This is the first snapshot of the FreeBSD/ia64 kernel. This kernel will not work on any real hardware (or fully work on any simulator). Much more needs to happen before this is actually functional but its nice to see the FreeBSD copyright message appear in the ia64 simulator.
