- On 32bit arch and type argument is int32_t, orig[m] * tomix[m] is
calculated first with int32 (possibility of overflow here) and then
cast to int64_t for assignment.
- bigger_type is sufficient for product and result.
- This makes sc_audiochan a list of only open audio chan.
- "SIMPLEQ_FIRST(&sc->sc_audiochan)->vc" is now "sc->hwvc".
No functional changes (except one debug message).
device is known to be quirky.)
Some of the most-widely-compatible methods of implementing USB Keyboard
NKRO depend on this Request to function as designed.
Issuing this Request is recommended by the HID 1.11 spec (7.2.6):
... "the host should not make any assumptions about the device's state
and should set the desired protocol whenever initializing a device."
The previous code asssumed reports would closely match the Bootstrap
Keyboard Protocol. This is no longer always the case, particularly
with higher-end keyboards.
with pending work items panics or accessing freed resources from the work
item will crash. The timeout needs to be handled gracefully by the driver
that implements the discard operation.
Fixes parts of PR 50725.
Now sc_audiochan contains opened audio chan (and first special
element) only.
First I splitted sc_audiochan into sc_audiochan which has
audio chan (and first special element) and sc_mixerchan
which has mixer chan only. However nobody else refers this
sc_mixerchan except additions to list and deletions from
list. So mixer chan's list is not necessary.
in having kernel support for this: the instruction set of the CPU is small,
and it can easily be emulated in userland entirely. There are also several
assumptions in the code that are not respected, and the slightest confusion
in the trap frame can lead to ring0 exploits.
vm86 has received zero maintenance. As far as I can tell, it was added
20 years ago in order to make doscmd work. But doscmd has not been
maintained either, and was removed from pkgsrc in 2011. dosbox can be used
instead: it does not require kernel support, and will produce better
results than our flimsy implementation.
Pass 1. (many pieces still in the tree)
