2020-04-28Use the same inittodr()/resettodr() implementation as on arm64/armv7/sparc64Mark Kettenis
and move it to the end of machdep.c. Rework the actual implementation for te MC14818 compatible RTC into something that can be used as a todr_handle. ok mpi@

2020-04-26Sanitize inittodr()/resettodr() implementation.Mark Kettenis
- move implementations next to eachother in the same file - remove pointless call to resettodr() in inittodr() - use OpenBSD define to get a minimum plausible time - if RTC time is before minimum plausible time, reject it - don't print "clock gained N days" on ramdisk Hopefully this implementation can serve as a model for unification into an MI implementation. ok mpi@

This is really just an I2C controller. ok patrick@

2020-04-22Knock out a few more well-known nodes that we don't intend to attach aMark Kettenis
driver to as well as nodes that start with a double underscore. ok patrick@
2020-04-22Add bcmsdhost(4), a driver for the Broadcom "sdhost" SD controllerMark Kettenis
found on the Raspberry Pi. The driver was ported from NetBSD by Neil Ashford and tobhe@. ok patrick@, tobhe@

present. Make sure bus_dmamap_alloc(9) allocates memory that meets that constraint. ok patrick@
2020-04-21Add an openbsd,dma-constraint property to the /chosen node and set itMark Kettenis

the Raspberry Pi 4. ok deraadt@
2020-04-19Initialize vmx_get_guest_faulttype() 'prot' to 0 instead of usingKenneth R Westerback
random stack garbage. CID 1492655 ok pd@
2020-04-19Add bcmpcie(4), a driver for the PCIe controller found on the Raspberry Pi 4.Mark Kettenis
In its current state the driver relies on the firmware for initializing the controller. Therefore it only really works when using the EDK2-based UEFI firmware. ok jsg@

2020-04-18Sync existing stacktrace_save() implementationsVisa Hankala
Upgrade stacktrace_save() to stacktrace_save_at() on architectures where the latter is missing. Define stacktrace_save() as an inline function in header <sys/stacktrace.h> to reduce duplication of code. OK mpi@

2020-04-15Switch powerpc to MI mplock implementation.Martin Pieuchot
Reduce differences with others architectures and make it possible to use WITNESS on it. Rename & keep the current recursive lock implementation as it is used by the pmap. Tested by Peter J. Philipp, otto@ and cwen@. ok kettenis@

2020-04-14Fix some of the more esoteric bus_space functions. TheMark Kettenis
bus_space_read_region_n, bus_space_write_region_n and bus_space_set_region_n functions were all broken. Same fix as arm64; Thanks to patrick@ for noting that mips64 had the same code. ok visa@

bus_space_read_region_n, bus_space_write_region_n and bus_space_set_region_n functions were all broken. Fixes mvneta(4) on arm64. ok patrick@
2020-04-12Add support for the _CCA method. This method indicates whether DMA isMark Kettenis
cache-coherent or not. To implement this, acpi(4) gets two bus_dma tags and passes the appropriate one when attaching devices based on _CCA. On i386/amd64, where for all practical purpose DMA is always cache-coherent, the two tags are the same. But on arm64 they are distinct. ok patrick@
2020-04-10Add omcm(4), omclock(4) and omsysc(4) drivers that support the new busMark Kettenis
structure that is used in current mainline Linux device trees. ok jsg@

2020-04-08vmm(4): add IOCTL handler to sets the access protections of the eptpd
This exposes VMM_IOC_MPROTECT_EPT which can be used by vmd to lock in physical pages. Currently, vmd just terminates the vm in case it gets a protection fault in the future. This feature is used by solo5 which uses vmm(4) as a backend hypervisor. ok mpi@ Patch from Adam Steen <adam@adamsteen.com.au>
2020-04-08vmm(4): handle cr0 writes more correctly for vmxpd
* Switch to using vcpu->vc_vmx_cr0_fixed[1|0] to check must be 0|1 bits, rather than the cpu capabilities. * Add the checks on the new values as per the SDM 2.5 CONTROL REGISTERS. 2.1 Bits 63:32 of CR0 and CR4 are reserved and must be written with zeros. Writing a nonzero value to any of the upper 32 bits results in a general-protection exception, #GP(0). 2.2 setting the PG flag when the PE flag is clear causes a general-protection exception (#GP). 11.5.1 Cache Control Registers and Bits, Table 11-5. Cache Operating Modes 2.3 CD: 0, NW: 1, Invalid setting. Generates a general-protection exception (#GP) with an error code of 0. *. Don't alway assume, if the guest is not disabling paging, they are enabling it, check the guest is actually enabling paging. also only read cr4 when we actually need it, not right at the start. ok mpi@ Patch from Adam Steen <adam@adamsteen.com.au>
