doesn't obtain the ports, gain and balance related parameters.
Those generally require reading from the hardware and therefore are much
more expensive to obtain. Modify OSS emulation to use the new ioctl
where possible.
This reduces CPU usage of mplayer during mp3 playback with my Thinkpad
from 20% to < 1% and from 50% to 20% during Xvid playback.
Review and comments from jmcneill@
compat_10_netbsd32_sys_semsys() (where the one parameter is already in
kernel space).
Note that the code in compat_10_netbsd32_sys_semsys() has always been wrong,
since it called compat_14_sys___semctl() - which would read 64bit values!
once the 'address' has been copied into an mbuf.
Add extra flags for 'struct msghdr.msg_flags' to indicate that the address
and control are already in mbufs, and that the uio structure is in userspace
for sending data, rename sendit() to do_sys_sendmsg() to ensure no old code
passes in random flags.
Changes to compat code to use new functions - removing some stackgap use.
Fix a 'use after free' in compat_43_sys_recvmsg.
I ***THINK*** the code that converts 'cmsg' formatted data is borked!
svr4_stream.c ought to be generated from svr4_32_stream.c during the build.
OSIOCGIFADDR -> OOSIOCGIFADDR
OSIOCGIFDSTADDR -> OOSIOCGIFDSTADDR
OSIOCGIFNETMASK -> OOSIOCGIFNETMASK
Also, one instance of needing to include <net/if.h> before
<compat/sys/sockio.h> due to use of IFNAMSIZ in the latter.
Discussed with christos.
compatibility with the older ioctls. This avoids stack smashing and
abuse of "struct sockaddr" when ioctls placed "struct sockaddr_foo's" that
were longer than "struct sockaddr".
XXX: Some of the emulations might be broken; I tried to add code for
them but I did not test them.
- Make linux_sys_rt_sigreturn() return EJUSTRETURN on success.
- Add missing rax to linux_sigcontext structure; and save/restore
its value like other members in linux_sendsig()/linux_sys_rt_sigreturn().
With valuable help from manu.
from doc/BRANCHES:
idle lwp, and some changes depending on it.
1. separate context switching and thread scheduling.
(cf. gmcgarry_ctxsw)
2. implement idle lwp.
3. clean up related MD/MI interfaces.
4. make scheduler(s) modular.
Make the same changes to the svr4 code.
Add some 'missing' simple_unlock(&fp->f_slock) to the svr4_32 version of this
code. These files now compare if feed the svr4_32 copy though:
sed -e 's/4_32/4/g;s/_P32//g'
Note in passing that the code paths that call simple_unlock(&fp->f_slock)
are completely broken.
