I am using gcc version 2.8.1. I must admit that this
is a bit old, but it was sufficient until now to build
parisc-linux kernels (and SOM executables for HP-UX).

[parisc-linux] make Image currently fails here too.

[Brian S. Julin]

My unsatisfied symbols are different, though:

ld: Unsatisfied symbols:
   fcacheline (code)
   pcacheline (code)

That code doesn't get much maintenance these days.  The usual cause of
failures is that code using headers from the palinux tree which define
macros which call functions which aren't part of that boot loader.

I ran into this yesterday, and in poking around with Bonsai, I believe
that this is because sammy's net/drivers/lasi_82596.c code includes
calls to these macros to do the cacheline flushes and purges, but prumpf
removed their definitions from include/asm-parisc/cache.h.

That's the (buggy IMHO) Lasi ethernet driver that uses strange custom
macros to flush the cache rather than the standard ones.  Basically

#define fcacheline(x) dma_cache_wback(&x, 32)
#define pcacheline(x) dma_cache_inv(&x, 32)

_might_ make it compile again.


It alse uses phys_to_virt/virt_to_phys rather than bus_to_virt/virt_to_bus
and generally needs to be fixed for the new DMA API soon.  If you're
happy just using a ramdisk, don't compile it in.
