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.
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().
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().
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.
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().
Simplified serveral parts of the initarm() to make the code clearer and
modified parts of initarm() as part of an on-going effort to abstract
out part of initarm() on various machines.
place (some moved from param.h)
Define several constants such as page table addresses in terms of other
constants.
Increase some of the limits :
MAXTSIZ 8MB -> 16MB
DFLDSIZ 16MB -> 128MB
MAXDSIZ 256MB -> 512MB
DFLSSIZ 512KB -> 2MB
This is necessary as the memory addresses being used for the cache clean
(if the CPU is a SA110) may have been remapped by the setttb() call and
thus the cache could loose sync with memory.
* Improve the midisyn layer a little.
* Add a driver for the Yamaha OPL[23] FM synths.
The opl driver is not finished yet; it sounds pretty awful.
For some strange reason I cannot get any FM sound from my SB64 cards,
but a regular SB16 works fine.
Instead use a flag to indicate that all user space access are blocked
during the cache op to ensure that user space virtual addresses correctly
expunged from the cache.
