Thank you for your comments.
It's good idea.
Because acpi_table_print() show 6byte oem_id,
how about XenIPF?
78 void acpi_table_print(struct acpi_table_header *header, unsigned long
phys_addr)
79 {
[snip...]
98 printk(KERN_DEBUG PREFIX
99 "%.4s (v%3.3d %6.6s %8.8s 0x%08x %.4s 0x%08x) @ 0x%p\n",
name,
100 header->revision, header->oem_id, header->oem_table_id,
101 header->oem_revision, header->asl_compiler_id,
102 header->asl_compiler_revision, (void *)phys_addr);
103 }
For example, how about the following sample?
ACPI: RSDP (v002 FUJITS ) @ 0x000000007f924000
ACPI: XSDT (v001 FUJITS PQ 0x00000003 FJ 0x00000001) @
