* Replace manyinstances of VM_WAIT with blocking page allocation flagsJeff Roberson2017-11-081-0/+4
| | | | | | | | | | | | | | | | | | | similar to the kernel memory allocator. This simplifies NUMA allocation because the domain will be known at wait time and races between failure and sleeping are eliminated. This also reduces boilerplate code and simplifies callers. A wait primitive is supplied for uma zones for similar reasons. This eliminates some non-specific VM_WAIT calls in favor of more explicit sleeps that may be satisfied without new pages.

* Move kernel dump offset tracking into MI code.Mark Johnston2017-10-181-5/+3
| | | | | | | | | | | | | | | | | | | | | | All of the kernel dump implementations keep track of the current offset ("dumplo") within the dump device. However, except for textdumps, they all write the dump sequentially, so we can reduce code duplication by having the MI code keep track of the current offset. The new dump_append() API can be used to write at the current offset. This is needed to implement support for kernel dump compression in the MI kernel dump code. Also simplify dump_encrypted_write() somewhat: use dump_write() instead of duplicating its bounds checks, and get rid of the redundant offset tracking.

* bhnd: Implement bhnd(4) platform device registration.Landon J. Fuller2017-09-274-15/+69
| | | | | | | | | | | | | | | | | | Add bhnd(4) API for explicitly registering BHND platform devices (ChipCommon, PMU, NVRAM, etc) with the bus, rather than walking the newbus hierarchy to discover platform devices. These devices are now also refcounted; attempting to deregister an actively used platform device will return EBUSY. This resolves a lock ordering incompatibility with bwn(4)'s firmware loading threads; previously it was necessary to acquire Giant to protect newbus access when locating and querying the NVRAM device.

| | | | | | | | | | | | | | | | | | A new 'u_long *sv_hwcap' field is added to 'struct sysentvec'. A process ABI can set this field to point to a value holding a mask of architecture-specific CPU feature flags. If an ABI does not wish to supply AT_HWCAP to processes the field can be left as NULL. The support code for AT_EHDRFLAGS was already present on all systems, just the #define was not present. This is a step towards unifying the AT_* constants across platforms.

* Use better hard-coded defaults for the cursor shape, and remove nearbyBruce Evans2017-08-191-3/+0

Hard-code base = 0, height = (approx. 1/8 of the boot-time font height) in all cases, and remove the BIOS/MD support for setting these values. This asks for an underline cursor sized for the boot-time font instead of various less hard-coded but worse values. I used that think that the x86 BIOS always gave the same values as the above hard-coding, but on 1 of my systems it gives the wrong value of base = 1. The remaining BIOS fields are shift_state and bell_pitch. These are now consistently not explicitly reinitialized to 0. All sc_get_bios_value() functions except x86's are now empty, and the only useful thing that x86 returns is shift_state. This really belongs in atkbdc, but heavier use of the BIOS to read the more useful typematic rate has been removed there. fb still makes much heavier use of the BIOS.

The structure takes 88 bytes on 64bit arches which is not negligible. Also, it cannot be easily found by other code, which e.g. caused duplication of some members of the structure to struct thread already. The change removes td_dbg_sc_code and td_dbg_sc_nargs which were directly copied from syscall_args. The structure is put into the copied on fork part of the struct thread to make the syscall arguments information correct in the child after fork. This move will also allow several more uses shortly.
