Macro Definition Documentation

◆ PH

#define PH (   IDENT)
Value:
u_pp(dg, "\n\t\t%s: %s, view count: %zu", #IDENT, \
xsysd->static_roles.IDENT ? xsysd->static_roles.IDENT->str : "<none>", \
xsysd->static_roles.IDENT ? xsysd->static_roles.IDENT->hmd->view_count : 0u);
u_pp
void u_pp(struct u_pp_delegate dg, const char *fmt,...) XRT_PRINTF_FORMAT(2
Formats a string and sends to the delegate.

Function Documentation

◆ p_can_open()

static bool p_can_open ( struct xrt_prober *  xp,
struct xrt_prober_device *  xpdev 
)
static
Todo:
add more backends

◆ p_create_system()

static xrt_result_t p_create_system ( struct xrt_prober *  xp,
struct xrt_session_event_sink *  broadcast,
struct xrt_system_devices **  out_xsysd,
struct xrt_space_overseer **  out_xso 
)
static
Todo:
Improve estimation selection logic.

◆ p_get_string_descriptor()

static int p_get_string_descriptor ( struct xrt_prober *  xp,
struct xrt_prober_device *  xpdev,
enum xrt_prober_string  which_string,
unsigned char *  buffer,
size_t  length 
)
static
Todo:
add more backends
Todo:
Todo:
make this unicode (utf-16)? utf-8 would be better...

◆ teardown_devices()

static void teardown_devices ( struct prober *  p)
static
Todo:
Free somewhere else
