Subject: [PATCH] ath10k: fix spectral scan for QCA9984 and QCA9888 chipsets
|
|
|
|
The spectral scan has been always broken on QCA9984 and QCA9888.
|
|
|
|
Introduce a hardware parameter 'spectral_bin_offset' to resolve this issue for
|
|
QCA9984 and QCA9888 chipsets. For other chipsets, the hardware parameter
|
|
'spectral_bin_offset' is zero so that existing behaviour is retained as it is.
|
|
|
|
In QCA9984 and QCA9888 chipsets, hardware param value 'spectral_bin_discard'
|
|
is 12 bytes. This 12 bytes is derived as the sum of segment index (4 bytes),
|
|
extra bins before the actual data (4 bytes) and extra bins after the actual
|
|
data (4 bytes). Always discarding (12 bytes) happens at end of the samples and
|
|
incorrect samples got dumped, so that user can find incorrect arrangement
|
|
samples in spectral scan dump.
|
|
|
|
To fix this issue, we have to discard first 8 bytes and last 4 bytes in every
|
|
samples, so totally 12 bytes are discarded. In every sample we need to consider
|
|
the offset while taking the actual spectral data. For QCA9984, QCA9888 the
|
|
offset is 8 bytes (segment index + extra bins before actual data).
|
|
|
|
Hardware tested: QCA9984 and QCA9888
|
|
Firmware tested: 10.4-3.5.3-00053
