[Bug 1767146] Re: No ACPI-table found, option -M 1.6 not found either

[Thomas Huth]

The QEMU project is currently considering to move its bug tracking to another 
system. For this we need to know which bugs are still valid and which could be 
closed already. Thus we are setting older bugs to "Incomplete" now.
If you still think this bug report here is valid, then please switch the state 
back to "New" within the next 60 days, otherwise this report will be marked as 
"Expired". Or mark it as "Fix Released" if the problem has been solved with a 
newer version of QEMU already. Thank you and sorry for the inconvenience.

Title:
  No ACPI-table found, option -M 1.6 not found either

Status in QEMU:
  Incomplete

Bug description:
  Currently writing a small kernel, when trying to detect memory blocks
  that contain ACPI information, no such block is found. When ran in
  Oracle Virtualbox, code runs flawlessly.

  Code that is detecting the ACPI-Info (with a bit of debug-output):

  ```
  multiboot_memory_map32_t* map = (multiboot_memory_map32_t*)mmap;
  for (uint32_t i = 0; i < size; i++) {
   Termutils::cout << map[i].type << "type of block  ";
          if (mmap[i].type == MULTIBOOT_MEMORY_ACPI_RECLAIMABLE) {
               Termutils::cout << "WE ARE INSIDE\n";
               fadt = (FADT*)(map[i].base_addr_low);
          }
   if (i % 9 == 0) {
    Termutils::cout << "\n";
   }
  }
  ```

  command qemu is run with:

  qemu-img create build/objects/test 500M
  qemu-system-i386 -hda $(APP_DIR)/clinl.iso -hdb ./build/objects/test

  The iso-image is (zipped) included as attachment.
