2020-11-12use RWLOCK_INITIALIZER() in DEFINE_MUTEX()Jonathan Gray
Gives rwlocks defined this way a non-NULL rwl_name. Move ttm_pool_shrink_scan() DEFINE_MUTEX use out of function scope to fix build with WITNESS after this change and expand macro to have a better name than "lock". Found by and ok semarie@
2020-11-09use a single preinitialised mutex for atomic64 fallback pathJonathan Gray
Previously we would initialise a variable specific mutex in ATOMIC64_INIT() or atomic64_set() but the drm code in multiple places zeroes memory and later accesses it without calling these resulting in a mutex with IPL_NONE instead of IPL_HIGH. Fixes a 'locking against myself' panic reported by Anthony Richardby on macppc with PowerBook5,6 and RV350. ok kettenis@

2020-11-07change from rwlock(9) to mutex(9) for linux rwlocksJonathan Gray
Linux rwlocks are read/write spin locks which don't sleep. Fixes a panic claudio@ reported with a WITNESS kernel on inteldrm(4) 'panic: acquiring blockable sleep lock with spinlock or critical section held (rwlock) drmvma' Patch from kettenis@ with a small tweak from me. ok kettenis@

- Reverse byte order on big-endian architectures (except on sparc64) - Add memory barriers Note that sparc64 is special as we use a little-endian mapping for PCI bus space, so we shouldn't reverse the byte order there. ok jsg@

2020-08-18Our usleep_range(min, max) implementation today is only taking accountMarcus Glocker
of the min value to delay. On the iMac11,2 this was too short, causing a timeout in the DP AUX transaction retry loop, leaving the eDP dark after the KMS initialization attempt. Affected code line for reference: sys/dev/pci/drm/drm_dp_helper.c:771, revision 1.11 Therefore we change the behavior of usleep_range(min, max) to delay the average value of min and max instead, which finally fixes the KMS initialization on the iMac11,2.

2020-07-07drm: use hi-res time to implement ktime_get(), ktime_get_real()cheloha
There seems to have been some confusion about the granularity of certain time interfaces in the Linux kernel when our DRM compatibility layer was written. To be clear: the Linux ktime_get() and ktime_get_real() interfaces are *high resolution* clocks. We should to implement them with high resolution interfaces from our own kernel. Thus, use microuptime(9) to implement ktime_get() and microtime(9) to implement ktime_get_real(). While here, ktime_get_raw_ns() should use ktime_get_raw(), not ktime_get(). Discussed with kettenis@ and jsg@. ok jsg@

2020-06-24kernel: use gettime(9)/getuptime(9) in lieu of time_second(9)/time_uptime(9)cheloha
time_second(9) and time_uptime(9) are widely used in the kernel to quickly get the system UTC or system uptime as a time_t. However, time_t is 64-bit everywhere, so it is not generally safe to use them on 32-bit platforms: you have a split-read problem if your hardware cannot perform atomic 64-bit reads. This patch replaces time_second(9) with gettime(9), a safer successor interface, throughout the kernel. Similarly, time_uptime(9) is replaced with getuptime(9). There is a performance cost on 32-bit platforms in exchange for eliminating the split-read problem: instead of two register reads you now have a lockless read loop to pull the values from the timehands. This is really not *too* bad in the grand scheme of things, but compared to what we were doing before it is several times slower. There is no performance cost on 64-bit (__LP64__) platforms. With input from visa@, dlg@, and tedu@. Several bugs squashed by visa@. ok kettenis@
