758c41b8cc - Use a TAILQ instead of parsing the array to find a free dmamap. 
- Inline busdma_alloc_dmamap, busdma_free_dmamap and bus_dmamap_sync_buf.

a56da6d0d2 Don't pass the kernel_pmap to pmap_fault_fixup() if the fault comes from 
kernel mode, always use the curthread pmap instead. There are valid cases
were we can fault on a user address from the kernel without pcb_onfault
being set.

8f47151b3b Remove the last use of pmap_initialized. 2005-06-10 13:31:30 +00:00
Alan Cox
1c245ae7d1 Introduce a procedure, pmap_page_init(), that initializes the 
vm_page's machine-dependent fields.  Use this function in
vm_pageq_add_new_page() so that the vm_page's machine-dependent and
machine-independent fields are initialized at the same time.

Remove code from pmap_init() for initializing the vm_page's
machine-dependent fields.

Remove stale comments from pmap_init().

Eliminate the Boolean variable pmap_initialized from the alpha, amd64,
i386, and ia64 pmap implementations.  Its use is no longer required
because of the above changes and earlier changes that result in physical
memory that is being mapped at initialization time being mapped without
pv entries.

f263522a45 MFP4: 
- Implement sampling modes and logging support in hwpmc(4).

- Separate MI and MD parts of hwpmc(4) and allow sharing of
  PMC implementations across different architectures.
  Add support for P4 (EMT64) style PMCs to the amd64 code.

- New pmcstat(8) options: -E (exit time counts) -W (counts
  every context switch), -R (print log file).

- pmc(3) API changes, improve our ability to keep ABI compatibility
  in the future.  Add more 'alias' names for commonly used events.

- bug fixes & documentation.

56e472e2b5 Add a new arm-specific option, ARM_USE_SMALL_ALLOC. If defined, it provides 
an implementation of uma_small_alloc() which tries to preallocate memory
1MB per 1MB, and maps it into a section mapping.

15ba408fd7 - Try to avoid calling malloc() in bus_dmamap_create() and bus_dmamem_alloc()

bus_dmamap_sync(), it's not needed anymore.

f1f49518d4 Write back affected pages in pmap_qremove() as well. This removes the need 
to change the DACR when switching to a kernel thread, thus making
userland thread => kernel thread => same userland thread switch cheaper by
totally avoiding data cache and TLB invalidation.

21fc316430 Change cpu_set_kse_upcall to more generic style, so we can reuse it 
in other codes. Add cpu_set_user_tls, use it to tweak user register
and setup user TLS. I ever wanted to merge it into cpu_set_kse_upcall,
but since cpu_set_kse_upcall is also used by M:N threads which may
not need this feature, so I wrote a separated cpu_set_user_tls.

06db52b609 Break out the definition of bus_space_{tag,handle}_t and a few other types 
into _bus.h to help with name space polution from including all of bus.h.
In a few days, I'll commit changes to the MI code to take advantage of thse
sepration (after I've made sure that these changes don't break anything in
the main tree, I've tested in my trees, but you never know...).
