Hello there,
I am in a situation where I am mangling RTP data in kernel space. I
have written a netfilter module which is responsible for encryption,
padding and ptime modification. The thing is that, encryption, padding
works just fine. Ptime modification involves two steps. When large
packets
I've been pondering making a very simple IO scheduler
one step above noop, just keeps everything in a big heap sorted by
position and a single cursor bouncing from head to tail shaving off
requests in a loop of ascending and descending sweeps.
Any gotchas I need to be aware of or can I simply

Thank you very much But I still have a minor confusion .
All I ran was this short program

well, before your program is loaded,

Hi there,
I was wondering whether setting DMA attributes like
DMA_ATTR_WRITE_BARRIER will have an effect
if I don't dma_unmap_single_attr() an area but merely
dma_sync_single() it after a transfer from
the device to the host memory. My problem is that I get an interrupt

The ongoing thread reminds me of a simple question I've had since I
first read about linux' mutiple I/O schedulers. Why is the choice of
I/O scheduler global to the whole kernel, rather than per-device or
similar?
Consider a system with both traditional rotating disks and SSDs - not
at all far

Hi Ben,
Please find the below the link to kernel power management related docs.
https://www.kernel.org/doc/Documentation/power/basic-pm-debugging.txt
This will explain about how /sys/power/ can be interactive.
You can refer /sys/power/pm_test file for testing the power
management
