[PATCH 1/5] m68k/atari: EtherNAT - change number of Atari interrupts to make room for EtherNAT interrupts
|[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]|
Hi All,The following patch is one in a series of patches in relation to getting interrupt-driven Ethernet and USB drivers supported on the Atari Falcon EtherNAT board. Whoever does have a Falcon with EtherNAT (and CT60, preferably) running Linux please try out this patch series to help testing these drivers. For convenience of testing, build the Ethernet and USB drivers as modules please.
Patches are relative to Geert's v3.3.0 (commit 29c8d8820b6eba2fb6cb2702fd06095a48083595).
Part 1 (this): make room for the EtherNAT interrupts - they appear at vectors 0xc3 (USB ISP1160) and 0xc4 (SMC91C111) Part 2: add platform data for the ISP1160 driver, fix the 91C111 interrupt source number (the 91C111 platform data had been added quite some time ago) Part 3: make sure the platform devices are added only if the EtherNAT card is actually present
Part 4: add usb/isp116x.h header to fix compile errors introduced in 2)Part 5: add Kconfig flag necessary to enable compilation of the ISP1160 driver
Both functions of the EtherNAT are correctly detected with this patch series. Some mysterious hardware fault in my Falcon does prevent the card to function properly, however (though at least the 91C111 part with timer polling did use to work in thee past).
The card interrupts are not being enabled by these patches yet. I need to discuss with Geert the best way of enabling them as close to the module loading time as possible.
