hw.c contains the following code:
static void ath9k_hw_init_interrupt_masks(struct ath_hw *ah,
enum nl80211_iftype opmode)
{
ah->mask_reg = AR_IMR_TXERR |
AR_IMR_TXURN |
AR_IMR_RXERR |
AR_IMR_RXORN |
AR_IMR_BCNMISC;
if (ah->intr_mitigation)
ah->mask_reg |= AR_IMR_RXINTM | AR_IMR_RXMINTR;
else
ah->mask_reg |= AR_IMR_RXOK;
...
}
mac.c contains the following code:
omask = ath9k_hw_set_interrupts(ah, ah->mask_reg & ~ATH9K_INT_GLOBAL);
ATH9K_INT_GLOBAL is 0x80000000 (hw.h)
reg.h contains the following definitions:
#define AR_IMR_TXMINTR 0x00080000
#define AR_IMR_RXMINTR 0x01000000
#define AR_IMR_TXINTM 0x40000000
#define AR_IMR_RXINTM 0x80000000
Is it correct that the call to ath9k_hw_set_interrupts is masking out what
appears to be the flag AR_IMR_RXINTM? I don't know enough about the code
to know what it all means, but at least in the definition of the mask_reg
field in hw.c, AR_IMR_RXINTM seems to be used in a manner that is quite
parallel to AR_IMR_RXMINTR, and AR_IMR_RXINTM seems to be conceptually
similar to AR_IMR_TXINTM, but neither of them is masked out.
thanks,
julia
