Subject: [9fans] shared memory
Date: Mon, 29 Jul 2002 13:13:37 +0200 [thread overview]
Message-ID: <15685.9057.72875.389455@nanonic.hilbert.space> (raw)
I am writing (or trying to :-)) the driver for the sis630 vga card. It
uses shared memory, i.e. the video memory comes from the normal ram of
the computer. At first it seemed to me I had to reserve memory for it
like a dma buffer, but after looking more closely to the linux driver,
it seems to me that something hardware is going on and that the memory
is reserved some way by the bios works as normal video memory. Does
anybody know how this should be treated?. Any pointers to info?.
