According to the syntax defined in C99, each struct/union field must have an
identifier. This patch adds names to the previously unnamed fields for C99
compatibility.
Here is a summary of the names (marked with a pair of *stars*) added.
struct trusty_mem:
union {
struct {
struct key_info key_info;
struct trusty_startup_param startup_param;
} *data*;
uint8_t page[CPU_PAGE_SIZE];
} first_page;
struct ptdev_remapping_info:
union {
struct ptdev_msi_info msi;
struct ptdev_intx_info intx;
} *ptdev_intr_info*;
union code_segment_descriptor:
uint64_t value;
struct {
union {
...
} low32;
union {
...
} high32;
} *fields*;
similar changes are made to the following structures.
* union data_segment_descriptor,
* union system_segment_descriptor,
* union tss_64_descriptor, and
* union idt_64_descriptor
struct trace_entry:
union {
struct {
uint32_t a, b, c, d;
} *fields_32*;
struct {
uint8_t a1, a2, a3, a4;
uint8_t b1, b2, b3, b4;
uint8_t c1, c2, c3, c4;
uint8_t d1, d2, d3, d4;
} *fields_8*;
struct {
uint64_t e;
uint64_t f;
} *fields_64*;
char str[16];
} *payload*;

currently, pass-thru devices are managed by per-vm's remapping entries
which is virtual based:
- MSI entry is identified by virt_bdf+msix_index
- INTx entry is identified by virt_pin+vpin_src
it works but it's not a good design for physical resource management, for
example a physical IOAPIC pin could belong to different vm's INTx entries,
the Device Model then must make sure there is no resource conflict from
application's level.
This patch change the design from virtual to physical based:
- MSI entry is identified by phys_bdf+msix_index
- INTx entry is identified by phys_pin
The physical resource is directly managed in hypervisor, a miss adding
entry will be found by hypervisor and return error message with failure.
