pass memory for vmem structs into the initialization function and
do away with the static pool of vmem structs.
remove special bootstrapping of the quantum cache pools of the kmem_va_arena
as memory for pool_caches is allocated via pool_allocator_meta which is
fully operational at this point.

78b0e18345 Report vmem(9) errors out-of-band so that we can use vmem(9) to manage 
ranges that include the least and the greatest vmem_addr_t.  Update
vmem(9) uses throughout the kernel.  Slightly expand on the tests in
subr_vmem.c, which still pass.  I've been running a kernel with this
patch without any trouble.

64311e1f9d Introduce a couple of new constants, VMEM_ADDR_MIN (the least possible 
address in a vmem(9) arena, 0) and VMEM_ADDR_MAX (the maximum possible
address, currently 0xFFFFFFFF).  Modify several boundary conditions so
that a vmem(9) arena can allocate ranges including VMEM_ADDR_MAX.
Update documentation and tests.

These changes pass the tests in sys/kern/subr_vmem.c.  To compile the
and run the test program, run "cd sys/kern/ && gcc -DVMEM_SANITY -o
subr_vmem ./subr_vmem.c && ./subr_vmem".

f4fa6bbef9 bump VMEM_HASHSIZE_MAX from 8192 to 65536. 2009-01-25 13:08:56 +00:00
pooka
8b32829eeb Change VMEM_HASHSIZE_INIT from 1 to 128. This mainly benefits 
quick-running or non-threaded rump jobs, where the rehash algorithm
does not have a chance to run.  For other cases it doesn't make
much difference, since the size will grow or decrease when the
rehash algorithm runs for the first time (t=10*hz currently).

2aa8aa0f8f Spans may never overlap. Overlapping spans mean memory corruption 
when used by kmem(9), for example.
Do sanity checks to detect such spans on DEBUG kernels.
