2022-07-15Implement support for framebuffers that don't start on a page boundary.Mark Kettenis
This happens on the new 14" and 16" Macbook Pro where we deliberately use a framebuffer that skips the first few lines to avoid "the notch". The offset of the first pixel is added to struct wsdisplay_fbinfo. The stride is added as well, mirroring the value returned by the WSDISPLAYIO_LINEBYTES ioctl, such that we can retire that one in the future. A compat ioctl is implemented to help the transition. The compat code will be removed after OpenBSD 7.3 has been released. ok miod@

2021-02-23timecounting: use C99-style initialization for all timecounter structscheloha
The timecounter struct is large and I think it may change in the future. Changing it later will be easier if we use C99-style initialization for all timecounter structs. It also makes reading the code a bit easier. For reasons I cannot explain, switching to C99-style initialization sometimes changes the hash of the resulting object file, even though the resulting struct should be the same. So there is a binary change here, but only sometimes. No behavior should change in either case. I can't compile-test this everywhere but I have been staring at the diff for days now and I'm relatively confident this will not break compilation. Fingers crossed. ok gnezdo@

2020-07-14Extend the interrupt API on arm64 and armv7 to be able to pass aroundPatrick Wildt
a struct cpu_info *. From a driver point of view the fdt_intr_establish_* API now also exist same functions with a *_cpu suffix. Internally the "old" functions now call their *_cpu counterparts, passing NULL as ci. NULL will be interpreted as primary CPU in the interrupt controller code. The internal framework for interrupt controllers has been changed so that the establish methods provided by an interrupt controller function always takes a struct cpu_info *. Some drivers, like imxgpio(4) and rkgpio(4), only have a single interrupt line for multiple pins. On those we simply disallow trying to establish an interrupt on a non-primary CPU, returning NULL. Since we do not have MP yet on armv7, all armv7 interrupt controllers do return NULL if an attempt is made to establish an interrupt on a different CPU. That said, so far there's no way this can happen. If we ever gain MP support, this is a reminder that the interrupt controller drivers have to be adjusted. Prompted by dlg@ ok kettenis@

2020-07-06Add support for timeconting in userland.Paul Irofti
This diff exposes parts of clock_gettime(2) and gettimeofday(2) to userland via libc eliberating processes from the need for a context switch everytime they want to count the passage of time. If a timecounter clock can be exposed to userland than it needs to set its tc_user member to a non-zero value. Tested with one or multiple counters per architecture. The timing data is shared through a pointer found in the new ELF auxiliary vector AUX_openbsd_timekeep containing timehands information that is frequently updated by the kernel. Timing differences between the last kernel update and the current time are adjusted in userland by the tc_get_timecount() function inside the MD usertc.c file. This permits a much more responsive environment, quite visible in browsers, office programs and gaming (apparently one is are able to fly in Minecraft now). Tested by robert@, sthen@, naddy@, kmos@, phessler@, and many others! OK from at least kettenis@, cheloha@, naddy@, sthen@

2020-05-25change wsdisplay attribute type from long to uint32_tJonathan Gray
miod explained it was initially a long as it was thought drivers may need to allocate storage but in practice they don't need more than 32 bits for an attribute. suggested and reviewed by miod@
2020-05-25rename wsdisplay alloc_attr() to pack_attr()Jonathan Gray
Suggested by John Carmack. miod agrees a rename would make sense and explained it was initially thought drivers may need to allocate storage but in practice they don't need more than 32 bits for an attribute. ok mpi@

Previously the device tree only described one but now it describes both. Do not attempt to set the global variable that points to a softc or register a watchdog if this has already been done. Fixes rebooting on the OMAP4 based PandaBoard-ES with a device tree from linux 4.15-rc1.
