bool "Enable full debugging output in IPW2200 module."
depends on IPW2200
---help---
- This option will enable debug tracing output for the IPW2200.
+ This option will enable low level debug tracing output for IPW2200.
- This will result in the kernel module being ~100k larger. You can
- control which debug output is sent to the kernel log by setting the
- value in
-
- /sys/bus/pci/drivers/ipw2200/debug_level
-
- This entry will only exist if this option is enabled.
+ Note, normal debug code is already compiled in. This low level
+ debug option enables debug on hot paths (e.g Tx, Rx, ISR) and
+ will result in the kernel module being ~70 larger. Most users
+ will typically not need this high verbosity debug information.
- To set a value, simply echo an 8-byte hex value to the same file:
-
- % echo 0x00000FFO > /sys/bus/pci/drivers/ipw2200/debug_level
-
- You can find the list of debug mask values in
- drivers/net/wireless/ipw2200.h
-
- If you are not trying to debug or develop the IPW2200 driver, you
- most likely want to say N here.
+ If you are not sure, say N here.

-/* *** THEORY OF LOCKING ***
- *
- * We have two different locks in the bcm43xx driver.
- * => bcm->mutex: General sleeping mutex. Protects struct bcm43xx_private
- * and the device registers.
- * => bcm->irq_lock: IRQ spinlock. Protects against IRQ handler concurrency.
- *
- * We have three types of helper function pairs to utilize these locks.
- * (Always use the helper functions.)
- * 1) bcm43xx_{un}lock_noirq():
- * Takes bcm->mutex. Does _not_ protect against IRQ concurrency,
- * so it is almost always unsafe, if device IRQs are enabled.
- * So only use this, if device IRQs are masked.
- * Locking may sleep.
- * You can sleep within the critical section.
- * 2) bcm43xx_{un}lock_irqonly():
- * Takes bcm->irq_lock. Does _not_ protect against
- * bcm43xx_lock_noirq() critical sections.
- * Does only protect against the IRQ handler path and other
- * irqonly() critical sections.
- * Locking does not sleep.
- * You must not sleep within the critical section.
- * 3) bcm43xx_{un}lock_irqsafe():
- * This is the cummulative lock and takes both, mutex and irq_lock.
- * Protects against noirq() and irqonly() critical sections (and
- * the IRQ handler path).
- * Locking may sleep.
- * You must not sleep within the critical section.
