Subject: [PATCH] hw/qxl: tracing fixes
Hans de Goede 93b7e3
Hans de Goede 93b7e3
Add two new trace events:
Hans de Goede 93b7e3
qxl_send_events(int qid, uint32_t events) "%d %d"
Hans de Goede 93b7e3
qxl_set_guest_bug(int qid) "%d"
Hans de Goede 93b7e3
Hans de Goede 93b7e3
Change qxl_io_unexpected_vga_mode parameters to be equivalent to those
Hans de Goede 93b7e3
of qxl_io_write for easier grouping under a single systemtap probe.
Hans de Goede 93b7e3
Hans de Goede 93b7e3
Change d to qxl in one place.
