MFC r1.20:

2005-10-17T00:20:47Z

Add a default value for VM_BCACHE_SIZE_MAX of 400MB. This is copied from amd64, and is a factor of 3 less than the value previously auto-sized on a 12GB machine, which would cause an overflow in calculations involving the maxbcache int, causing bufinit() to loop forever at boot.

2004-11-20 02:29:50 UTC Remove UAREA_PAGES.

Make PAGE_SIZE and related quantities signed on sparc64. (They are signed

quantities on every other architecture.) This change is required in order to move pmap_prefault() out of the pmap and into the machine-independent layer.

Deal with 'options KSTACK_PAGES' being a global option.

Migrate the thread stack management functions from the machine-dependent

2003-06-14T23:23:55Z

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().

Get rid of the TODO macro in the few places that still need work; either

comment it out or change to explicit panics. It conflicts with things like #if TODO in drivers.

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

Move MI stuff out of MD param.h files.

It can all still be overridden in the MD files should need suddenly arise.

Move the CTASSERT macro from MD code to systm.h alongside KASSERT so other

2002-04-01T21:55:00Z

code can use it. This takes a single constant argument and fails to compile if it is 0 (false). The main application of this is to make assertions about structure sizes at compile time, in order to validate assumptions made in other code. Examples: CTASSERT(sizeof(struct foo) == FOO_SIZEOF); CTASSERT(sizeof(struct foo) == (1 << FOO_SHIFT)); Requested by: jhb, phk
