Hi.
It is known that no semaphore synchronization should be
used inside an interrupt handler.
Anyway, I am looking at a freeBSD device driver (written by
a profesionist) and there are semaphores inside an interrupt
handler's subroutine.
Since I should port to linux that driver, I ask you how can

Hello folks,
This video was shared by Alison to me. Here Dave Chinner talks about some
of the recent events which transpired at lkml and kernelnewbies. I think we
all have witness the said event and some of us have participated in this so
called flame war.
Besides all that, this is a very good
Hi list,
I'm writing a net device driver for my final project in college. But the
half-finished device doesn't support interrupt yet(those hardware guys...)
So I'm wondering if there is some way to poll the device for its status
and events.
Google tells me 'NAPI' uses a polling mechanism, but
Hi.
Following LDD3, I am dealing with wait queues, on a 2.6.10.
My loop is like:
while(enough()){
prepare_to_wait(queue_head, queue_entry, TASK_INTERRUPTIBLE);
atomic_set(flag, 0);
if (!atomic_read(flag, 0))
schedule();
finish_wait(queue_head, queue_entry);
}

Please use a modern kernel, 2.6.10 is _very_ old and no one can do
anything about it, and those that could, have long forgotten what was in
it.
good luck,

Hey Kevin,
This is basically because of udevd calling modprobe when the new
VFs are created. The code in the ixgbe driver that causes the VFs to
be created would be the function call pci_enable_sriov(). This
brings about a chain of events resulting in the ixgbevf getting
loaded.
I assume you
Hi, all:
Going through fs/buffer.c, I find that
bh_lru_lock() is a macro which can be local_irq_disable() or
preempt_disable().
#ifdef CONFIG_SMP
#define bh_lru_lock() local_irq_disable()
#define bh_lru_unlock() local_irq_enable()
#else
#define bh_lru_lock() preempt_disable()

Hi,
I have an x86_64 machine (F21) on which ixgbevf is not loaded.
I notices that when running
modprobe ixgbevf max_vfs = 10 (or any other number), this triggers
loading of ixgbevf driver.
I will appreciate if someone can exaplain the implementation
Hi Valdis,
Thanks for your warning. I feel like I believe in my group and those
engineers. In fact, implementing interrupts is part of the plan, but,
yes, the prototype is really buggy However they are trying hard to
fix it, and I should not stand by just to watch, waiting for the
deadline,
Hi phil,
Thanks for your reply! I googled timer, it might be a solution except
that interval granularity is a little bit large. This device is for high
performance network. I'm not sure whether the missmatch will cause problem.
And I just figured another potential solution, to use soft interrupt
