RE: [Xen-devel] SMBIOS starts at 0xe9000 (out of range)
|
Sorry, the tables are mapped
separately.
You are right
:)
Nope, a straw poll of three boxes shows one of my
boxes with tables in the range 0xe0000-0xf0000, and one with the tables in
high memory just below 4GB! It?s only the header that has to be in the range
0xf0000-0xfffff.

Yes, I see it, robios copies just the entry point (but not the

I think the tables should be copied to >0xf0000 as well.
I encountered an implementation which maps
0xf0000 (and nothing below that...)

I?ll have to double check,
but I think that rombios picks up the smbios tables from 0xe9000 and
copies them into the valid range. We do it that way because only
rombios knows the memory layout 0xf0000-0xfffff.

By the spec
it should be somewhere between 0xF0000 to 1MB,
There is even a
comment in the code:
/* SMBIOS
entry point -- must be written to a 16-bit aligned
address
between 0xf0000 and 0xfffff.
*/
struct smbios_entry_point {
...
Any reason
for that?
Thanks,
Guy.
