ufshci: Add functions for UTP Task Management
This commit adds UTP Task Management Request functions and revisits the
UTR/UTRM construction logic.
It also introduces ufshci_ctrlr_cmd_send_task_mgmt_request(), which
will be used for timeout handling in a follow-up commit.
Test: I temporarily added the code below to the ufshci_ctrlr_start()
function to test it on a Galaxy Book S.
static void
ufshci_ctrlr_start(struct ufshci_controller *ctrlr)
{
...
/* Test: Task Mangement Request */
ufshci_printf(ctrlr,
"Test: Task Mangement Request\n");
struct ufshci_completion_poll_status status;
status.done = 0;
ufshci_ctrlr_cmd_send_task_mgmt_request(ctrlr,
ufshci_completion_poll_cb, &status,
UFSHCI_TASK_MGMT_FUNCTION_QUERY_TASK, 0, 0, 0);
ufshci_completion_poll(&status);
if (status.error) {
ufshci_printf(ctrlr,
"ufshci_ctrlr_cmd_send_task_mgmt_request failed!\n");
return;
}
uint32_t service_response;
service_response =
status.cpl.response_upiu.task_mgmt_response_upiu.output_param1;
ufshci_printf(ctrlr, "Task Management Service Response = 0x%x\n",
service_response);
