New Xen boot infrastructure proposal
...me changes proposal.
It is linked with EFI development but not only.
Since the beginning Xen image and other needed stuff
could be loaded into memory according to multiboot
protocol. (e.g. implemented by GRUB). It means that
current implementation of Xen takes info about current
system config from multiboot_info_t structure (it is
copied from original place in assembly files and then
passed as an argument to __start_xen()) and some other
BIOS sources if needed (e.g. VGA config, EDD data).
Later when EFI come into the scene there was no significant
change in that. multiboot_info_t structure and others
are ini...

x86_64 platform : addresses type
...as in
typedef struct {
u32 flags;
u32 mem_lower;
u32 mem_upper;
u32 boot_device;
u32 cmdline;
u32 mods_count;
u32 mods_addr;

aout_symbol_table_t aout_sym;

} u;
u32 mmap_length;
u32 mmap_addr;
} multiboot_info_t
However, on x86_64 using gcc, addresses as well as unsigned long are 64
bits long.
It seems that luckily mmap_addr is below 2*32-1, making the u32 type
acceptable
so far (for instance in function __start_xen, where the memory map is
turned into
another structure) but what would it cost to cha...

[PATCH] Increasing E820MAX
We found machines with >32 E820 memory map entries, where Xen fails to
boot (but Linux does boot fine). The native Linux (both x86 and x86_86)
already has:
#define E820MAX 128 /* number of entries in E820MAP */

[V6 PATCH 0/7]: PVH dom0....
Hi,
V6: The only change from V5 is in patch #6:
- changed comment to reflect autoxlate
- removed a redundant ASSERT
- reworked logic a bit so that get_page_from_gfn() is called with NULL
for p2m type as before. arm has ASSERT wanting it to be NULL.
Tim: patch 4 needs your approval.
Daniel: patch 5 needs your approval.
These patches implement PVH dom0.
Patches 1 and 2
