pub const PRESENT_MIN_TICKS: u64 = 1;Expand description
Minimum scheduler ticks between two throttled presents, shared by the VGA console writer and the video driver.
TIMER_HZ is 100 (one tick = 10 ms): allow one present per tick so
pending console work is eligible within 10 ms. Paths that pace themselves
(the userspace compositor, Framebuffer::swap_buffers) bypass this gate.
