e7c0cc5d9a Add NVMe command passthrough support. 2016-06-04 16:11:50 +00:00
bouyer
bdf10c852a The UART in the allwiner SoCs is not full-compatible with the 16550, and 
it's not a 16750 either. Like the 16750 it has the IIR_BUSY interrupt,
which is triggered when writing to LCR while the chip
can't accept it. But unlike the 16750, it has a specific register,
HALT, to allow writing to the LCR and divisor registers, and then
commit the changes.
Tested on an A20 SoC, changing the baud rate while keeping the
tty device open and incoming data.

5407bb6145 - change major number limit for MI devices from 255 to 511, 
because twe is already using 332
- clarify that new MI devices should go to this file
  instead of majors.{ws,usb,std,tty,storage}
- fix major number conflict about hdmicec vs tty

OKed by matt@
the expression "previously not MI" is suggested by matt@ too.

62976e3600 Move linux_work.c and workqueue.h from sys/external/bsd/drm2 to 
sys/external/common so that they can be used by others.

LGTM from riastradh@

These should really live outside sys/external, but that can be decided
later

8089a0f85d PR/50483: David A. Holland: fix building of assym.d: 
1. use += to add to DEPS
	2. move inclusion of rules mk. files before the rules are defined
	   so that variables are set.

Now we get on amd64:

	mkdep: ignoring acpi_wakeup_low.d: No such file or directory
	mkdep: ignoring amd64func.d: No such file or directory
	mkdep: ignoring busfunc.d: No such file or directory
	mkdep: ignoring copy.d: No such file or directory
	mkdep: ignoring cpu_in_cksum.d: No such file or directory
	mkdep: ignoring cpufunc.d: No such file or directory

because there are no rules to generate those, but it is harmless.

78da7b9d09 Always include the "vfs" attribute (module). Although all of the 
ufs/xxx file systems depend on the vfs attribute, it is not required
that any file system actually be built-in to the kernel.  (At least
on some architectures, file system modules can be loaded at boot
time.)

7c02a5abd6 Whether or not the semaphore code is loaded as a module or built-in, its 
sysctl data belongs with the module code.  Move it from kern/init_sysctl.c
to kern/uipc_sem.c

While here, add a new sysctl variable kern.posix.semcnt (current count of
semaphores) to complement the existing kern.posix.semmax (maximum number
of semaphores).

ce0411ffa7 A makeoptions `DEFWARNINGS', forcibly disabling all ${CC} warnings, is only 
used by hpcmips's NULLCONF, which doesn't even build for other causes.

If some source doen't build and needs a workaround, that should be deal with
by modifying per-file ${CC} options (e.g. COPTS.foo.c+=-fno-xxx).  Let's not
use DEFWARNINGS any longer.

eee4f24ac6 According to nxr.netbsd.org, nothing uses MEMORY_DISK_IMAGE. Retire it. 
Premature design and its build rule bloats Makefile.kern.inc.  There are

(When kernel will be built as relocatable, embedding binary data will be much
easier, and md(4), splash(4), and ksyms(4) will all benefit.)
