2019-05-22i386/amd64 apm(4): Ignore APM_UPDATE_TIME events.cheloha
The APM spec defines an APM_UPDATE_TIME event that is meant to cause the driver to rebase the system's wallclock against the RTC. The event itself is apparently caused by occasional blackout periods where interrupts cannot be delivered, which might cause the system to miss a tick. The problem is that on systems where these events are frequent this constantly erodes the system wallclock. The RTC is not the greatest clock in the world so these systems are always playing catch-up. ntpd(8) is a far better clock corrector than rebasing against the RTC, so it should be safe to simply ignore the event. We continue to record the event for userspace listeners, but we do not call inittodr(9) on receipt of the event. Linux has ignored the event since v2.6.21: https://github.com/torvalds/linux/commit/c1d370e167d66b10bca3b602d3740405469383de#diff-d85b9a44da8e5dfb2fb1bcbd304c2a6c Discovered by jcs@. Discussed a bit with jcs@, tedu@, deraadt@. Fix tested by jcs@. "I think we should ignore the event" deraadt@
2019-05-22Allow loading of bigger ucode. This implementation uses the UEFI memoryMark Kettenis

2019-05-17Mitigate Intel's Microarchitectural Data Sampling vulnerability.Philip Guenther
If the CPU has the new VERW behavior than that is used, otherwise use the proper sequence from Intel's "Deep Dive" doc is used in the return-to-userspace and enter-VMM-guest paths. The enter-C3-idle path is not mitigated because it's only a problem when SMT/HT is enabled: mitigating everything when that's enabled would be a _huge_ set of changes that we see no point in doing. Update vmm(4) to pass through the MSR bits so that guests can apply the optimal mitigation.

2019-05-15Add support to the BIOS bootloader for random kernel base VAMike Larkin
This diff adds support to be able to load a randomly linked kernel VA (subject to some range restrictions). This change has been in snaps for a few days without any fallout. ok deraadt@

invalidation is done by mips64 pmap when the branch emulation page is made executable. Originally, the pmap_proc_iflush() call was necessary. The instruction cache invalidation was added in pmap_protect() after the FPU emulation was introduced. OK miod@

Add a first cut of x86 page table walker to vmd(8) and vmm(4). This function is not used right now but is a building block for future features like HPET, OUTSB and INSB emulation, nested virtualisation support, etc. With help from Mike Larkin ok mlarkin@
2019-05-12Between the broken GIC-500 on the RK3399 and differences in the secure modeMark Kettenis
configuration done by TF-A between boards we have to shift the priorities that we use for both the architected ICC_PMR_EL1 register and the memory mapped priority registers on the GIC in different ways. Make this explicit in the code and try to handle all the cases we care about. This includes QEMU and RK3399 boards that still use the TF-A version provided by Rockchip. Seems to make the rockpro64 run stable with a GENERIC kernel. ok drahn@, patrick@

2019-05-11Add fusbtc(4) to support the Fairchild FUSB302 USB Type-C controller.Patrick Wildt
A Type-C controller has multiple tasks. Even though the orientation of the plug doesn't matter for the user, it matters for the hardware. To be able to know how to route the SuperSpeed pins you need to know which way the plug is connected. Also you need to know if you're a sink/source or device/host. To get the first connection, you toggle between the modes until you find a connection. In case you see that a sink is connected, you can turn on USB Vbus to power the sink. This driver explicitly does not implement USB's Type-C state machine, but if we get more and more of these controllers it might be worth doing. Also there's no support for Power Delivery messages yet. ok kettenis@

a part of the free memory list, terminating it prematurely.
2019-05-06Enforce store/load order when setting or clearing AST flag on mips64Visa Hankala
Make sure that any preceding stores become visible to other CPUs before setting the AST flag in need_resched() and signotify(). This should prevent a very unlikely case with inter-CPU ASTs where the receiving CPU uses stale state. When clearing the AST flag in ast(), ensure that the clearing store is performed before any other memory accesses in the AST handler. Otherwise, there is a slight risk of losing an AST request that gets posted while the handler is running. OK guenther@
2019-05-06Issue write-write barrier before sending IPI on mips64Visa Hankala
The barrier ensures that any lockless state changes become visible to other CPUs before the IPI is sent. Otherwise, a receiving CPU might still observe an old state when it processes the interrupt. OK guenther@
2019-05-06Fix unintentional delay of ASTs on MP mips64Visa Hankala
Make the interrupt and trap return paths check for ASTs with interrupts disabled. If there is no pending request, interrupts are kept disabled until return to userspace. This fixes delayed processing of an AST request that arrives from another CPU after the AST flag has been checked but before the CPU has finished the return path. The IPI that follows the setting of the AST flag forces kernel re-entry and recheck of AST. Noticed by guenther@

region is properly allocated by the firmware. Move the .bss clearing to locore.S because the section has to be ready when the stack is taken into use. This additionally makes the C environment more consistent at the start of mips_init().
