Hey, just an update.
I did find minimal time to play with 6.2 kernel and basic device tree earlier this year, but it would not boot for me.
It seems I may need to debug the platform code on 6.1 first, to get it to boot, before using 6.2+ as some code already was dropped that may have impact on the Zaurus series.
While I had not the time to dig much deeper yet, I came across these :
https://www.phoronix.com/news/Linux-6.4-PCMCIA-Char-Droppinghttps://www.phoronix.com/news/Linux-6.4-CardBus-USB-DroppingLooking further, it does impact Zaurus:
https://lore.kernel.org/all/Y07d7rMvd5++85BJ@owl.dominikbrodowski.net/While the PXA PCMCIA driver is not yet to be purged and marked as + (eg may stay) it still an indicator of whats to come:
+ PCMCIA_PXA2XX - pxa2xx_base.c pxa2xx_base.h pxa2xx_mainstone.c pxa2xx_sharpsl.c : bugfix in 2016
Wireless CF cards typically used by Zaurus already have a [-] (eg get removed if no maintainers found):
[-] drivers/net/wireless/intersil/hostap/hostap_cs.c no specific activity since tree reorganization 2015
[-] drivers/net/wireless/intersil/orinoco/orinoco_cs.c no specific activity since tree reorganization 2015
[-] drivers/net/wireless/intersil/orinoco/spectrum_cs.c no specific activity since tree reorganization 2015
[-] drivers/net/wireless/marvell/libertas/if_cs.c no specific activity since tree reorganization 2015
Long story short, while it looks like there is not much userbase anymore and I am on my own to keep this platform alive, I have not yet caved in, but with the extra pressure mounting to support / maintain extra stuff to keep it usuable (eg PCMCIA and cards), its getting beyond not only my very limited spare time to dedicate to this, but also my skill set as well.
So anyone keen to keep this stuff in the kernel, may pitch it to the kernel mailing list
I still have some laptops with CardBus and PCMCIA and I expect others have too, but it will be seen if kernel support is to remain on the long run..
Good News is 6.1 is a LTS and if we get it to boot on Zaurus we should be good for some time to come, but the writing is clearly on the wall....
Cheers,
Greg
