Subject: [PATCH] hw/qxl: tracing fixes
|
|
|
|
Add two new trace events:
|
|
qxl_send_events(int qid, uint32_t events) "%d %d"
|
|
qxl_set_guest_bug(int qid) "%d"
|
|
|
|
Change qxl_io_unexpected_vga_mode parameters to be equivalent to those
|
|
of qxl_io_write for easier grouping under a single systemtap probe.
|
|
|
|
Change d to qxl in one place.
