Description Roland Mainz 2004-06-20 19:02:27 UTC 
RFE: The Xserver should have an option to define the page size (on systems which
support multiple page size) and default to 64KB (e.g. anything better than the
"default" 8KB page size).

Prototype patch for 2004-10-09-trunk

The patch adds a new "-pagesize" option on platforms with MPSS API support
(=Solaris) and sets the default to 512k pages.

Sorry about the phenomenal bug spam, guys.  Adding xorg-team@ to the QA contact so bugs don't get lost in future.
Comment 4 Daniel Stone 2007-04-07 14:23:42 UTC 
alan, since it's only available on solaris, your call: is there any point in applying it?
Comment 5 Alan Coopersmith 2007-04-09 13:48:25 UTC 
I don't think we need this on Solaris, since we have the generic ppgsz tool to set
preferred page sizes for processes without having to modify every process to set
it's preferred page sizes.
