Subject: Re: [bigmem-patch] 4GB with Linux on IA32
Date: Mon, 16 Aug 1999 23:29:27 -0700 [thread overview]
Message-ID: <199908170629.XAA23911@pizda.davem.net> (raw)
In-Reply-To: <199908162328.QAA24338@google.engr.sgi.com> (kanoj@google.engr.sgi.com)
For example, on a 2.2.10 kernel:
[kanoj@entity kern]$ gid __va | grep drivers
drivers/char/mem.c:124: if (copy_to_user(buf, __va(p), count))
drivers/char/mem.c:142: return do_write_mem(file, __va(p), p, buf, count, ppos);
Ok, this one could be a problem.
drivers/scsi/sym53c8xx.c:572:#define remap_pci_mem(base, size) ((u_long) __va(base))
Sparc specific ifdef'd code, it doesn't matter for ix86.
drivers/video/creatorfb.c
...
drivers/sbus/char/zs.c
More Sparc specific drivers.
So in essence there are only two spots in mem.c which you might need
to worry about on ix86.
Later,
