Linville, Johannes Berg Cc: Vladimir Kondratiev, linux-wireless, Luis R . Rodriguez Addressed Luis's input: - typos, formatting, names, style etc. - kill all #ifdef's like #if 0 - use dynamic printk and kill more #ifdefs - did "dynamic printk" style variand for hex. dump - moved wil6210 under "atheros cards" in Kconfig. This require some changes around to not depend on ath.ko module I did it in 2 patches for now, to simplify discussion regarding Kconfig changes I kept "driver version", as it was requested by customers; and I see some 600+ drivers in today's kernel use it.

Linville, Johannes Berg Cc: Vladimir Kondratiev, linux-wireless, Luis R . Rodriguez Card wil6210 by Wilocity supports operation on the 60GHz band See http://wireless.kernel.org/en/users/Drivers/wil6210 for more info This development snapshot supports: - STA, PCP (AP-like mode in 60g) and monitor modes - security works for STA mode, not integrated yet for PCP mode - PCP limited to 1 connected STA Using 2 cards in STA and PCP mode, one can assemble fully functional BSS. throughput of 1.2Gbps achieved with iperf In the monitor mode, card is able to capture either control or non-control frames (due to hardware limitation). Wil6210 card have on-board flash memory for the firmware, card comes pre-flushed and no firmware download required on the run time.

Longer explanation: while clear-on-read is good for production mode, it makes debugging much harder - reading ISR registers clears interrupt, and one can no more monitor ISR with debugfs. So, when debugging ISR flows - and they still need some debugging - one have to use W1C mode. That's why it is still present. There are exactly 2 #ifdefs: one in ISR acknowledge routine, and other one in ISR configuration routine. Converting this #ifdef to run-time switch (say, module parameter) is possible, but I am not sure it would be better - changing ISR mode will cause reset; ans code will not more readable. > > The second patch no longer applies as a new driver was merged.

I meant, can you auto detect the preference for this option instead of requiring a Kconfig entry? Ie, can you infer what the desired path should be by poking at the driver? If not can you consider folding the #ifdef juju code into a helper such as #ifdef CONFIG_FOO static void bar() { apples() } #else static void bar() { oranges() } #endif Luis ^ permalink raw reply [flat|nested] 14+ messages in thread

Since I'm CC'ed on your patches (not sure why) I'll offer the opinion that you should add interrupt and IO access tracing rather than reading registers with some debug thing ;) johannes ^ permalink raw reply [flat|nested] 14+ messages in thread

Usually, you start digging into ISR registers when something stalled when it should not. At this point, you want to discover that, for example, some interrupt bit not came up. Then, you may try to manually set it writing into register. If you trace, it will flood dmesg, impacting performance, in normal situation; and will not let you analyze and recover from abnormal one.

Well I wasn't thinking printk, but rather trace events, so you can record it to the buffer and not have the big overhead etc. > I need "manual control" here.

Well its tied pretty heavily to the firmware which BTW is open and GPLv2. Your driver does not need firmware (yet). Why exactly carl9170 would use MODULE_VERSION though... or need it.. is perhaps Christian can clarify on.

Well, to make the api level of the firmware interface which is used by the driver accessible through modinfo without having to load the module. So a script check whenever the api matches by testing modinfo of the driver and fwinfo of the fw. However, this information is also printed out when the firmware is loaded/parsed.
