avail mem is calculated ptoa(uvmexp.free), not ptoa(uvmexp.free - bufpages),

like on other ports. uvmexp.free is already adjusted by the uvm_pagealloc
calls used to get the buffer pages. (reported by mrg)

45faa60d85
Added a new function map_chunk() used during init_arm() when setting up
...
the kernel page tables. map_chunk() replaces running a loop, calling
map_entry() and in addition where possible it will use L1 section mappings
or L2 large page mappings instead of L2 small page mappings in order to
reduce the TLB entried needed for the kernel.

Implement address validation as a separate function db_validate_address().

Use this function to validate the page table entries for all reads and
writes.

Remove the definition of CURRENT_PAGEDIR_HOLE and CURRENT_PAGEDIR_BASE
...
as they are no longer reference.
Move ALT_PAGE_TBLS_BASE from 0xf3c00000 to 0xf0c00000.
Increase the size of the KERNEL_VM_SIZE by 16MB now that 0xf3xxxxxx is free.

Use KERNEL_VM_SIZE to calculate the number of page tables needed for

the kernel data area.
Don't map the proc0 L1 page table into the L2 page tables space.
1998-08-29 03:17:27 +00:00
99bb4b6b6b
Rewritten pmap_pte() not to use the mapping of the L1 page table within
...
the L2 pages tables (CURRENT_PAGEDIR_HOLE).
Don't map the L1 page table into the L2 page table space any more (easy
reference hack) in pmap_allocpagedir().

More reworking in initarm().
...
Further cleanup and simply the allocation and mapping of the kernel
pagetables and static data pages.
Removed the page directory page table as it is no longer necessary.
Changed the allocation of the proc0 L1 page table and L2 page table
that maps the page tables to map these pages into kernel virtual
address space.
Updated for pv_addr_t argument changes to pmap_bootstrap().
1998-08-28 02:58:41 +00:00
133f5c93f0
Updated for pmap_bootstrap() argument change. Modify ofw_configmem()
...
to obtains pv_addr_t structures for the proc0 L1 page table and the proc0
pagetable that maps page tables.
Use the virtual address from the pv_addr_t structure for the proc0 L1 page
table when calling pmap_bootstrap rather than relying on a special mapping
at PAGE_DIRS_BASE.
Modify ofw_construct_proc0_addrspace() for similar changes to
ofw_configmem().
Remove the kernel_pde page table in ofw_construct_proc0_addrspace() as it
it now longer needed.
1998-08-28 02:52:37 +00:00

Modify the arguments to pmap_bootstrap() to take a pv_addr_t structure
...
for the page table to map kernel pagetables (kernel_ptpt). This means
that the pm_vptpt field is now valid for the kernel_pmap.
Use constants from vmparam.h in pmap_allocpagedir().

"COMPAT_11 + COMPAT_12 + COMPAT_13" doesn't work - these are based on

definition, not 1 or 0. Also, since all pre-1.4 releases require

out part of initarm() on various machines.
