acorn26. This bumps the KVA reservation from 4MB to 16MB and avoids
long hangs on my Cubietruck under IO. acorn26 is kept as it does have a
ridiculous low 32MB KVA limit.
As Masao Uebayashi pointed to me, UFS_EXTATTR_AUTOSTART, LFS_EXTATTR_AUTOSTART
and UFS_EXTATTR_AUTOCREATE are not used anywhere in the code. Remove them
as they have been obsolete for a long time:
UFS_EXTATTR_AUTOSTART was replaced by mount -o extattr
LFS_EXTATTR_AUTOSTART was created to match obsolete UFS_EXTATTR_AUTOSTART
UFS_EXTATTR_AUTOCREATE was replaced by sysctl vfs.ffs.extattr_autocreate
This change just brings UFS1 extended attribute *support* in the kernel,
extended attributes are not enabled unless three conditions are met:
1) filesystem is UFS1 (newfs -O1)
2) .attribute/system and .attribute/user directories are created at fs root
3) filesystem is mounted with -o extattr
Some GENERIC kernels are obviously memory constrained, the extended
attributes options were not enabled for them, but just added commented out.
(kernel were considered memory constrained if QUOTA option was disabled)
There are quite a few configs that are missing some COMPAT_NN options
in ways that don't make sense; this should probably get cleaned up
too, but for the time being I've not added or removed anything.
replaced by the make option COPY_SYMTAB set to any value. The copy of
the symbol table is no longer put into a buffer in kern_ksyms.o, but a
small helper object. This object is build first with a dummy size, then
the kernel is linked to compute the real dimension of the symbol table
buffer. After that, the helper object is rebuild and the kernel linked
again.
but add a second argument to it to indicate whether the TLB/caches need to be
flushed. Default cortex to pmap_needs_fixup = 1. But check the MMFR3 field
to see if the fixed can be skipped.
Use a cf_flag bit 0 to indicate whether the A9 L2 cache should disable (bit 0 = 1)
or enabeld (bit = 0).
With these changes, the A9 MMU can use traverse caches to do MMU tablewalks
Also, make sure all memory has the shareable bit for the A9.
WSDISPLAY_COMPAT_USL using the following rules:
- If WSEMUL_ is commented out, add commented out out WSDISPLAY_COMPAT_USL
- If INSTALL or obviously memory constrained, add WSDISPLAY_DEFAULTSCREENS=1
and commented out WSDISPLAY_COMPAT_USL
- Otherwise add WSDISPLAY_COMPAT_USL
Some of the INSTALL configs for larger memory machines are probably suitable
for adding WSDISPLAY_COMPAT_USL.
Now wsconscfg(8) should be able to switch VTs when expected.
Implemented after no objection from tech-kern to the following:

Move the extern for cpu_reset_address to the same file.
Add cpu_reset_address_paddr.
Kill cpu_reset_v4_MMU_disable.
if cpu_reset_address is NULL, then the MMU will be disabled.
unwanted sideeffects in the RB_ASKNAME case. This fixes PR/46732.
No longer wrap MD cpu_rootconf(), as hp300 port stores reboot information
as a side effect. Instead call MI rootconf() from MD code which makes
rootconf() now a wrapper to setroot().
Adjust several MD routines to set the global booted_device,booted_partition
variables instead of passing partial information to setroot().
Make cpu_rootconf(9) describe the calling order.
source file as the entropy-pool code itself. Move it to std. This
will be cleaned up more when I split the sources up as they should be.
This fixes build breaks on several ports. Thanks to Havard Eidnes for
pointing them out.
