Subject: [PATCH] ath10k: increase BMI timeout
|
||||
|
||||
When testing a 9888 chipset NIC, I notice it often takes
|
||||
almost 2 seconds, and then many times OTP fails, probably due
|
||||
to the two-second timeout.
|
||||
|
||||
[ 2269.841842] ath10k_pci 0000:05:00.0: bmi cmd took: 1984 jiffies (HZ: 1000), rv: 0
|
||||
[ 2273.608185] ath10k_pci 0000:05:00.0: bmi cmd took: 1986 jiffies (HZ: 1000), rv: 0

||||
[ 2277.294732] ath10k_pci 0000:05:00.0: bmi cmd took: 1989 jiffies (HZ: 1000), rv: 0
|
||||
|
||||
So, increase the BMI timeout to 3 seconds.

Subject: [PATCH] ath10k: log when longer bmi cmds happen
|

|
||||
This lets one have a clue that maybe timeouts are happening
|
||||
when we just aren't waiting long enough.

Subject: [PATCH] ath10k: add BMI parameters to fix calibration from
|
||||
DT/pre-cal
|
||||
|
||||
QCA99X0, QCA9888, QCA9984 supports calibration data in
|
||||
either OTP or DT/pre-cal file. Current ath10k supports
|
||||
Calibration data from OTP only.
|
||||
|
||||
If caldata is loaded from DT/pre-cal file, fetching board id
|
||||
and applying calibration parameters like tx power gets failed.
|
||||
|
||||
error log:
|
||||
[ 15.733663] ath10k_pci 0000:01:00.0: failed to fetch board file: -2
|
||||
[ 15.741474] ath10k_pci 0000:01:00.0: could not probe fw (-2)
|
||||
|
||||
This patch adds calibration data support from DT/pre-cal
|
||||
file. Below parameters are used to get board id and
|
||||
applying calibration parameters from cal data.
|
||||
|
||||
EEPROM[OTP] FLASH[DT/pre-cal file]
|
||||
Cal param 0x700 0x10000
|
||||
Board id 0x10 0x8000
|
||||
|
||||
Tested on QCA9888 with pre-cal file.
