Hi everybody,
I worked with the QoS parameters trying to understand why, checking
them within the firmware, they don't seems to have the correct values
even if they were set correctly by the driver.
I think that there could be an error in the b43.h file:
/* SHM offsets to the QOS data structures for the 4 different queues. */
#define B43_QOS_PARAMS(queue) (B43_SHM_SH_EDCFQ + \
(B43_NR_QOSPARAMS * sizeof(u16) *
(queue)))
#define B43_QOS_BACKGROUND B43_QOS_PARAMS(0)
#define B43_QOS_BESTEFFORT B43_QOS_PARAMS(1)
#define B43_QOS_VIDEO B43_QOS_PARAMS(2)
#define B43_QOS_VOICE B43_QOS_PARAMS(3)
/* QOS parameter hardware data structure offsets. */
#define B43_NR_QOSPARAMS 22
Each EDCF parameters set take up 32 byte (in the firmware the offset
between 2 EDCFQ is 0x010 that is equivalent to 0x020 if the offset was
expressed in byte). This means that the B43_NR_QOSPARAMS must be set
to 16.
With the value equal to 16 I can access correctly the aifs, cwcur,
cwmax, etc within the firmware.
What do you think about that?
regards.
Lorenzo.
