The code is trying to create an ath11k directory on debugfs
root, but that fails when there is a second radio (and thus
second instance of the driver).
Hi Ben,
IPQ8074 is soc and it does not need second debugfs entry, its on
AHB.
QCA6390 is a pci card and multiple debug entries are needed if
multiple cards are available,
I am planning to post a patch with bus specific abstraction function
which creates single debugfs for soc based radios and multiple
entries for PCI based radios.
AHB:
debugfs/ath11k/IPQ8074/
PCI
debugfs/ath11k/QCA6390_0001:01:00.0/
debugfs/ath11k/QCA6390_0000:01:00.0/
I appreciate your feedback on this!
Why not just stick with the way ath10k does, having the ath11k
debugfs entry be
under the phy debugfs directory?
Maybe there is a high-level design document for the ath11k driver
somewhere that
explains how and why it is architected with the ath11k base object
holding multiple
phy objects?
The initial ath11k driver was supporting IPQ8074, its an SOC and has
3-radios under wifi0,
- few entries in debugfs are common for SOC,all these are under
debugfs/ath11k/IPQ8074/
"simulate_fw_crash"
"soc_dp_stats"
Ok, so one 8074 firmware instance is handling multiple radios, and if
firmware crashes, then
it would take down every radio at once?
- few entries are per radio, these are under
debugfs/ath11k/IPQ8074/mac0/
"ext_tx_stats"
"ext_rx_stats"
"pktlog_filter"
debugfs/ath11k/IPQ8074/mac1
"ext_tx_stats"
"ext_rx_stats"
"pktlog_filter"
debugfs/ath11k/IPQ8074/mac2
"ext_tx_stats"
"ext_rx_stats"
"pktlog_filter"
And, very curious to know if you are able to get multiple QCA6390
NICs
running on the
same system, I'm seeing all sort of problems including NICs not
always
showing up in lspci
and such.
I am not aware of this, like to understand the output of, qrtr-lookup
cmd
Based on my testing with debugs, whatever driver I pulled down from
the ath tree had zero
chance of working due to immediate crash. So, have you been able to
test multiple
6390 radios yet?
I am not working on 6390.
How do I do this qrtr-lookup command?
https://github.com/andersson/qrtr, this has the tools.
Also please share the dmesg | grep ath11k log with both radios.
I understand its crashing, please share the ath11k boot logs.
Thanks
Anil
