RE: [RFC] Dropping Alpha sparse mapping support from X

I don't use X on EV4 but I do have a 21066 UDB machine that I still run.
I hope that dropping total support for EV4 isn't on the table unless
someone has a better Alpha that they will ship me for the cost of
shipping.

Subject: [RFC] Dropping Alpha sparse mapping support from X

Hi,
I'd like to drop support for non-BWX Alphas (EV4 and original EV5) from
X. These machines can't load/store to single bytes and require special
sparse memory mappings.

The code required to select which functions (sparse, dense) is
convoluted, adds an extra layer of indirection, probably gets close to
zero usage, and even less testing.

Does anyone use X on EV4 or EV5 (not EV56, EV56 has BWX)?

Thanks,
Matt Turner
