The gvp11_setup() function was probably a relic from the times before module parameters. Since gvp11_xfer_mask appears to be required for some Amiga systems to set the DMA mask, I'd best send a patch to add such a module parameter ... Do you know any details around the use of DMA masks for Amiga WD33C93 drivers, Geert? Cheers, Michael >

Doh, it's been a while, and I never had an affected system. Probably it's needed on A2000 with an accelerator card and GVP II SCSI, to prevent DMA to RAM banks that do not support fast DMA cycles.

Thanks, that's good enough for me. Linux 2.0 had this comment: |/* * DMA transfer mask for GVP Series II SCSI controller. * Some versions can only DMA into the 24 bit address space * (0->16M). Others can DMA into the full 32 bit address * space. The default is to only allow DMA into the 24 bit * address space. The "gvp11=0xFFFFFFFE" setup parameter can * be supplied to force an alternate (32 bit) mask. */ | |We now handle that (since 2.6.35) through masks defined in gvp11_zorro_tbl[] (though I note these don't account for unaligned addresses such as implied by the example in the comment. Are unaligned DMA buffers still possible today?). Would that cover the 'A2000 with accelerator' case? | || I'm happy to send a patch if an override to the device default DMA mask is still necessary. (Incidentally - did you ever publish the m68k full history tree anywhere in git?) Cheers, Michael > > Gr{oetje,eeting}s, > > Geert >

From: Arnd Bergmann <arnd@arndb.de> Most of the patches I sent so far for the -Wmissing-prototype warnings have made it into linux-next now. There are a few that I'm resending now as nobody has picked them up, and then a number of fixes that I found while test-building across all architectures rather than just the ones I usually test. The first 15 patches in this series should be uncontroversial, so I expect that either a subsystem maintainer or Andrew Morton can apply these directly. For the last two patches, these might still need some debate about how to handle them. I added a Kconfig option to turn off most of the missing prototype warnings in the architectures that nobody has fixed yet, see patch 16 for those. The last patch does cause some known warnings and likely unknown ones for architectures other than x86 and arm, so applying it now will bring new problems, but not applying it also means that new warnings creep in, so I think this is mainly a question of what the best timing is for having this in linux-next.
