The et(4) driver supports PCI Express Ethernet adapters based on
the Agere/LSI ET1310/ET1301 integrated MAC/PHY.
The et(4) driver was written by Sepherosa Ziehau for DragonFlyBSD,
ported to OpenBSD by Jonathan Gray and subsequently ported to NetBSD
by Kaspar Brand.
vm_page *) "reverse" lookup code from uvm_page.h to uvm_page.c, to
help migration to not do that.
Likewise move per-page metadata (struct vm_page *) -> physical
address "forward" conversion code into *.c too. This is called
only low-layer VM and MD code.
lookup code from uvm_page.h to uvm_page.c.
This code is used by some pmaps to lookup per-page state (PV) from
per-segment metadata (struct vm_physseg). This is not needed if
UVM looks up physical segment once in fault handler, then directly
passes it to pmap. This change helps transition to that model.
The only users of vm_physseg_find() are pmap_motorola.c and
powerpc/ibm4xx/pmap.c.
Tested By: Compiling and running powerpc/ibm4xx/pmap.c
(evbppc/conf/OPENBLOCKS266)
in UVM external API, uvm_extern.h. Because most users care only
virtual memory.
Device drivers use bus_dma(9) to manage physical memory. Device
drivers pull in bus_dma(9) API, bus_dma.h. bus_dma(9) implementations
pull in UVM internal API, uvm.h.
Tested By: Compiling i386 ALL kernel
plaintext into into an encrypted image and back into plaintext by
doing rump I/O on /dev/cgd. There is one test to check that giving
the same password for both encryption and decryption produces the
same plaintext and another to check that giving a different passwords
does not produce the same plaintext.
This could be fairly easily extended to test all feature of cgd
(hint hint). For example, now cgd.conf is included in cvs, but
the only reason for that is that without further hacking cgdconfig
uses /dev/random quality random to generate the salt for a
pkcsetcetc_kdf2 cgconfig -g, and making an automated test block on
the entropy pool is just not good form. Details are everything.
