I need to obtain a uefi variable so I went looking at the API in
include/linux/efi.h. I found the following definition:
/*
* The maximum size of VariableName + Data = 1024
* Therefore, it's reasonable to save that much
* space in each part of the structure,
* and we use a page for reading/writing.
*/
struct efi_variable {
efi_char16_t VariableName[1024/sizeof(efi_char16_t)];
efi_guid_t VendorGuid;
unsigned long DataSize;
__u8 Data[1024];
efi_status_t Status;
__u32 Attributes;
} __attribute__((packed));
But according to the specs the variable I need to obtain is 2k bytes.
Should I expect trouble :-p
Regards,
Arend
