| | * | | | | | | | | | | | x86: reserve EFI memory map with reserve_earlyHuang, Ying2008-06-05

Because EFI memory map is allocated by bootloader, if it is not reserved by reserved_early(), it may be overwritten through address returned by find_e820_area().

This patch changes that type to an 'int', to allow this sanitize routine to also be used on larger maps (larger than the 256 count that fits in a char). The legacy BIOS E820 interface of course does not change; that remains at 8 bits for this count, holding up to E820MAX == 128 entries. But the kernel internals can handle more when those additional memory map entries are passed from the BIOS via EFI interfaces.

The EFI interface, if present, is capable of passing memory map entries for these larger node counts. This patch requires an earlier patch that rewrote code depending on these array sizes from using E820MAX explicitly to size loops, to instead using ARRAY_SIZE() of the applicable array. Another patch following this one will provide the code to pick up additional memory entries passed via the EFI interface from the BIOS and insert them in the following, now enlarged, arrays.

The legacy interface is limited to E820MAX == 128 memory entries, and that "E820MAX" manifest constant was used as the size for several arrays and loops over those arrays. The primary change in this patch is to change code loop sizes over those arrays from using the constant E820MAX, to using the ARRAY_SIZE() macro evaluated for the array being looped. That way, a subsequent patch can change the size of some of these arrays, without breaking this code. This patch also adds a parameter to the sanitize_e820_map() routine, which had an implicit size for the array passed it of E820MAX entries. This new parameter explicitly passes the size of said array. Once again, this will allow a subsequent patch to change that array size for some calls to sanitize_e820_map() without breaking the code. As part of enhancing the sanitize_e820_map() interface this way, I further combined the unnecessarily distinct x86_32 and x86_64 declarations for this routine into a single, commonly used, declaration. This patch in itself should make no difference to the resulting kernel binary. [ mingo@elte.hu: merged to -tip ] Signed-off-by: Paul Jackson <pj@sgi.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

Of course, for non-x86, you kind of have to expect drivers to be well-behaved, so non-x86 can probably avoid this simply because there are less relevant drivers involved. Here's a UNTESTED patch for x86 that may or may not compile and work, and which serializes (on a compiler level) the IO accesses against regular memory accesses. __read[bwlq]()/__write[bwlq]() are not serialized with a :"memory" barrier, although since they still use "asm volatile" I suspect that i practice they are probably serial too. Did not look very closely at any generated code (only did a trivial test to see that the code looks *roughly* correct). Signed-off-by: Ingo Molnar <mingo@elte.hu>
