If xe_gt_clock_init() failed to recognise the crystal clock,     gt->info.timestamp_base is 0, which makes idledly_units_ps also 0.     The subsequent DIV_ROUND_CLOSEST(..., idledly_units_ps) is then a     divide-by-zero and panics the kernel.\n  2. The tick-to-ns conversions are done in u32:        idledly * idledly_units_ps, (maxcnt - 1) * 1000     Both overflow u32 before DIV_ROUND_CLOSEST() sees them.\n  3. If IDLE_WAIT_TIME reads back as 0, maxcnt evaluates to 0 and     the maxcnt - 1 clamp wraps to 0xFFFFFFFF in u32.\n  4. The register only stores whole ticks, so the clamped ns value has     to be converted to ticks and back. DIV_ROUND_CLOSEST() can round     that conversion up past maxcnt:\n       maxcnt = 640 ns, one tick = 666664 ps\n       clamp:        maxcnt - 1        = 639 ns       ns -> ticks:  639000 / 666664   = 0.958 -> rounds to 1 tick       tick -> ns:    1 * 666664 / 1000 = 667 ns\n     667 ns is programmed into RING_IDLEDLY, but 667 >= maxcnt (640),     so xe_gt_WARN_ON() fires again on every subsequent init.\nReturn early if timestamp_base is 0 (the unknown-crystal path).Do the conversions in u64 via the *_ULL() helpers so they cannot wrap.Clamp with a floor (DIV_ROUND_DOWN_ULL) so the programmed delay staysstrictly below maxcnt, and guard the maxcnt == 0 case with a zero delaywhile still writing RING_IDLEDLY so INHIBIT_SWITCH_UNTIL_PREEMPTED iscleared.\nv2: Drop the redundant warn on the timestamp_base == 0 path;    xe_gt_clock_init() already warns on an unrecognised crystal clock.    Keep the early return to avoid the divide-by-zero. - Vinay\nv3: Field-mask the RING_IDLEDLY write with REG_FIELD_PREP(IDLE_DELAY, ...)    instead of writing the raw tick count, which could clobber    INHIBIT_SWITCH_UNTIL_PREEMPTED and reserved bits. Split the    inhibit-switch clear from the maxcnt clamp so a set inhibit bit no    longer forces a needless delay overwrite when the delay itself is    already valid. Use gt_to_xe(gt) instead of gt_to_xe(hwe->gt).\n(cherry picked from commit
