Improved locking (not that we actually use it on a uniprocessor, but one day :)
Removed unneeded splvm's
tweaked pmap_clean_page code to only flush the cache if the page is mapped in the current pmap (based on diff from richard E)
Adopted pv entry allocation mechanism from i386.
Laid framework for returning ptp's when we've finished with them rather than holding onto them till the process exits.
ptp's are now allocated with a uvm object for the pmap, means that we can walk a list to free them off in pmap_release, until they get freed off by pmap_remove.
Also implemented a page zeroing function when the processor is idling. Note that hpcarm may wish to disable this.
I believe this code to be stable, if anyone has any problems please shout up.
and with the comment '4.2BSD TCP/IP bug compat. Not recommended'
Add commented out 'TCP_DEBUG # Record last TCP_NDEBUG packets with SO_DEBUG'
(All hail amiga and atari which make some attempt to automate the
multiplicity of config files...)
option for System V semaphores. It appears that there are no overrides
in the code and each file has the following added.
options SYSVSEM # System V semaphores
+#options SEMMNI=10 # number of semaphore identifiers
+#options SEMMNS=60 # number of semaphores in system
+#options SEMUME=10 # max number of undo entries per process
+#options SEMMNU=30 # number of undo structures in system
options SYSVSHM # System V shared memory
If anyone thinks that this is incorrect for any of these files, please
correct it.
Note - the i386 port was not forgotten. It was done separately.
Move the files from footbridge that are cats specific.
Remove EBSA285 kernel as people should be able to use the generic cats kernel for EBSA285 systems.
them define __HAVE_PCIIDE_MACHDEP_COMPAT_INTR_ESTABLISH
in pci_machdep.h and pciide_map_compat_intr() only calls
pciide_machdep_compat_intr_establish() if that preprocessor
define exists.
Ports that don't need to do this no longer need to supply a
dummy function.
each vm_page structure. Add a VM_MDPAGE_INIT() macro to init this
data when pages are initialized by UVM. These macros are mandatory,
but ports may #define them to nothing if they are not needed/used.
This deprecates struct pmap_physseg. As a transitional measure,
allow a port to #define PMAP_PHYSSEG so that it can continue to
use it until its pmap is converted to use VM_MDPAGE_MEMBERS.
Use all this stuff to eliminate a lot of extra work in the Alpha
pmap module (it's smaller and faster now). Changes to other pmap
modules will follow.
to reserve the first 2MB for the kernel. Use the netwinder specific
files. Add pci_attach_hook for init the pci devices. Add and alternate
id for the PCI ISA bridge.
