Proposal for a new PCI function call

2001-04-12 Thread Steve Modica

Hi All,

We found recently that the acenic driver for the 3com gigabit ethernet card does
not enable 64 bit DMAs.  (this is done by setting the appropriate mask in
pci_dev->dma_mask).

Jes suggested that the appropriate way to fix this would be to create a function
like pci_enable_dma64 and then have the driver call that, rather than directly
setting this value (a small handful of drivers do this now).

I think the function idea would let us do some sanity checking to make sure
drivers weren't setting this to 64bit on non-64 bit busses and stuff.

Anyhow, so long as no one has any heartburn with this, we'll try to put
something together and submit it.  I'm not subscribed to the list *yet* (need to
get procmail setup), so please leave me in the CC line.

Thanks!
Steve

I agree with this line of thinking.  The various academics studying
geology have been warning California about "The Big One" for years now,
and no one seems to care anymore.  

I don't think anyone's being lazy and I certainly don't have the
information to comment on the size of their butts.  So I'd rather just
assume they were working very hard on other things (like getting TPC-H
benchmarks to run!)

Perhaps it's none of my business, but it doesn't seem very sporting to
just turn something on that breaks stuff and say "you had fair
warning".  Why not shut it back off, issue a statement saying it works
now and will be re-enabled on June 10th or something, and everyone must
do thus and so or they will break on that day?

Vague things like "it'll be turned on real soon now" or ASAP really mean
"never" since admins always have things with real deadlines at the top
of their list.
