part of x_mutable_command_id_exp_desc_t is x_mutable_command_list_exp_flags_t - does it mean we can specify in advance when getting CommandID which part of next append are going to mutate?

[MichalMrozek]

yes, that's the goal

[zzdanowicz]

ok, thanks

@zzdanowicz The mutable command id descriptor does not currently contain the command list flags, only the command flags. The command list properties reports out both command list and command flags.

Is it a requirement that the command list flags be built into the command id descriptor? The command flags should be sufficient.

[zzdanowicz]

Yes, command flags. I just added (embargo) definitions, for the development purposes before official header arrives.
Treat them as temporary and only for sake of development - did I got it right?

typedef uint32_t ze_mutable_command_exp_flags_t;
typedef enum _ze_mutable_command_exp_flag_t {
    ZE_MUTABLE_COMMAND_EXP_FLAG_KERNEL_ARGUMENTS = ZE_BIT(0),
    ZE_MUTABLE_COMMAND_EXP_FLAG_GROUP_COUNT = ZE_BIT(1),
    ZE_MUTABLE_COMMAND_EXP_FLAG_GROUP_SIZE = ZE_BIT(2),
    ZE_MUTABLE_COMMAND_EXP_FLAG_GLOBAL_OFFSET = ZE_BIT(3),
    ZE_MUTABLE_COMMAND_EXP_FLAG_SIGNAL_EVENT = ZE_BIT(4),
    ZE_MUTABLE_COMMAND_EXP_FLAG_WAIT_EVENTS = ZE_BIT(5),
    ZE_MUTABLE_COMMAND_EXP_FLAG_FORCE_UINT32 = 0x7fffffff
} ze_mutable_command_exp_flag_t;

#define ZE_STRUCTURE_TYPE_MUTABLE_COMMAND_ID_EXP_DESC (ze_structure_type_t)0x00040001

typedef struct _ze_mutable_command_id_exp_desc_t {
    ze_structure_type_t stype;
    const void *pNext;
    ze_mutable_command_exp_flags_t flags;
} ze_mutable_command_id_exp_desc_t;
