[Xen-devel] [Q] why is DIRECT_PCI_STR_LEN 160?

[Akio Takebe <takebe_akio@xxxxxxxxxxxxxx>]

Hi,

Why is DIRECT_PCI_STR_LEN 160?
I'd like to know why the qemu says at the following point
"qemu: too many pci pass-through devices".


  #define DIRECT_PCI_STR_LEN 160
  char direct_pci_str[DIRECT_PCI_STR_LEN];
  void xenstore_parse_domain_config(int hvm_domid)
  {
[... snip ...]
              if ( strlen(dev) + strlen(direct_pci_str) > DIRECT_PCI_STR_LEN ) {
                  fprintf(stderr, "qemu: too many pci pass-through devices\n");
                  memset(direct_pci_str, 0, DIRECT_PCI_STR_LEN);
                  goto out;
              }

Best Regards,

Akio Takebe
