add support for edp, dp and hdmi on haswell and haswell ult.
vga, dvi and specific configurations like ulx are unimplemented.
remaining issue: edp link training always fails (time out).
the problem is that segio doesnt check segment attributes
and it can't really in case of SG_FAULT which can be
inherited from pseg and toggle at any time.
so instead of returning -1 from fault into the fault$cputype
handler which then panics when fault happend kernel mode,
we jump into segio's waserror() block just like in the
demand load i/o error case (faulterror()).
make sure the loop terminates and doesnt get stuck at
name == aname. avoid memrchr() as it conflicts with
libc on unix (drawterm). declare namelenerror() as
static.
calculate alloc flag before waserror(), as compilers like
gcc will not notice the value changing later because
setjump() restores the old value due to callee-saves.
change is applies here to make it easier to merge with
drawterm.
thanks to aiju for debugging this; used to cause drawterm
memory leak until compiled with gcc -O0.
turns out on real hardware, the front falls off if we write
the completion queue doorbell registers without consuming
an entry. so only write the register when we have processed
something.
timerdel() did not make sure that the timer function
is not active (on another cpu). just acquiering the
Timer lock in the timer function only blocks the caller
of timerdel()/timeradd() but not the other way arround
(on a multiprocessor).
this changes the timer code to track activity of
the timer function, having timerdel() wait until
the timer has finished executing.
basic NVMe controller driver, reads and writes work.
"namespaces" show up as logical units.
uses pin/msi interrupts (no msi-x support yet).
one submission queue per cpu, shared completion queue.
no recovery from fatal controller errors.
only tested in qemu (no hardware available).
commiting this so it can be found by someone who has
hardware.
on thinkpad x1v4, the PCMP structure resides in upper reserved memory
pa=0xd7f49000 - while system memory ends at 0x0ffff000; so we have to
vmap() it instead of KADDR().
the RSD structure for ACPI might reside in low memory, so we sould
KADDR() in that case.
devmouse controls the screen blanking timeout, so move the
code there avoiding cross calls between modules. the only
function that needs to be provided is blankscreen(), which
gets called with drawlock locked.
the blank timeout is set thru /dev/mousectl now, so kernels
without devvga can set it.
blanking now only happens while /dev/mouse is read. so this
avoids accidentally blanking the screen on cpu servers that
do not have a mouse to unblank it.
- add some milisecond timestamps to the status change debug printing
- flush the packets in the queue on deassoc to avoid processing old pae
packets on next association.
- make roaming timeout shorter (60 -> 20 seconds)
- automatically timeout and restart wpa/pae blocked state
- fix printing race when essid gets changed underneath seprint
from openbsd driver, it seems the Centrino Advanced-N 6030 and 6235
cards share the same device revision as the 6205 (Type6005). Also
changing the device revision field from 4 to 5 bits.
- drivers enable short preamble and sort timeslot depending
on the ap beacon capinfo field (bss->cap)
- wifi sets short preamble bit in capinfo on association request
- wifi sets short timeslot bit when ap advertized it in beacon
