Subject: framebuffer mmap
Date: Thu, 09 Oct 2003 10:58:22 +0200	[thread overview]
Message-ID: <3F85232E.6090604@gazeta.pl> (raw)

hello mm-everybody	

i'm just writing my own framebuffer driver for device acessed only via 
parallel port (there is no way to direct read/write it's memory)

i just want to use memory allocated in kernel module, and acess it 
application with mmmap (and of course flush this memory to device 
peridicaly)

q1: where is documentation of writing own mmap  functions
q2: what fields need to be set in  mmap function implementation
q3: what kind of memory allocation i should use inside driver
      (kmalloc, vmalloc, with GFP_KERNEL or FGP_USER?)
q4: how to remap (or not?) in mmap function

q5: is there any simply way to build acess for non-direct memory ?
     i mean for each byte read/write to this
     memory need to be called my own function

please answer to my priv (mailto:krom@gazeta.pl) too
thx
