| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: The AmigaOne platform, encompassing the X5000 and A1222 at this time, is based on the mpc85xx platform, but includes some things not listed in the device tree. Some custom devices, like CPLD, could be added to the device tree with an overlay, or other means. However, some cannot easily be done, such as the power button interrupt. The directory will also become a location to add AmigaOne platform drivers, such as the aforementioned CPLD, and its children.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Linkage is controlled by two make knobs: WANT_COMPAT - Prefer to link against the compat ABI. NEED_COMPAT - Link against the compat ABI or fail to build. Supported values are "32", "soft", and "any". The latter meaning pick the first[0] supported compat ABI. This can be used to provide test binaries for compat ABIs or to link ABI-specific programs. [0] We currently support only one compat ABI at a time, but this may change in the future and some code in this commit is structured to ease that change.

This handler is invoked when devices are added or removed. - When an ACPI_NOTIFY_DEVICE_CHECK event posts, rescan the parent bus device. Note that strictly speaking we only need to rescan the specified device, but BUS_RESCAN is what is available, so we rescan the entire bus. - When an ACPI_NOTIFY_EJECT_REQUEST event posts, detach the device associated with the ACPI handle, invoke the _EJ0 method, and then delete the device. Eventually this might be changed to vector notify events to devd in userspace where devctl can be used instead to permit more complex actions such as graceful unmounting of filesystems.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GCC compilers set __FreeBSD__ statically to a build-time determined targeted version (which in ports always matches the build host's version). This means that when building any version (12 or 13, etc.) of riscv or some other architecture via GCC on a 12.x host, __FreeBSD__ will always be set to 12. As a result, __FreeBSD__ cannot be used to reliably detect the target FreeBSD version being built. Instead, __FreeBSD_version from either <sys/param.h> (in the kernel) or <osreldate.h> (in userland) should be used. This changes the gets() test in libc++ to use __FreeBSD_version from <osreldate.h>.

* | Explicitly initialize the memory buffer to store O_ICMP6TYPE opcode.Andrey V. Elsukov2019-10-151-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By default next_cmd() initializes only first u32 of opcode. O_ICMP6TYPE opcode has array of bit masks to store corresponding ICMPv6 types. An opcode that precedes O_ICMP6TYPE, e.g. O_IP6_DST, can have variable length and during opcode filling it can modify memory that will be used by O_ICMP6TYPE opcode. Without explicit initialization this leads to creation of wrong opcode. Reported by: Boris N. Lytochkin Obtained from: Yandex LLC MFC after: 3 days Notes: svn path=/head/; revision=353545

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Atomics are used for page busy and valid state when the shared busy is held. The details of the locking protocol and valid and dirty synchronization are in the updated vm_page.h comments.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | busy acquires while held. This allows code that would need to acquire and release a very large number of page busy locks to use the old mechanism where busy is only checked and not held. This comes at the cost of false positives but never false negatives which the single consumer, vm_fault_soft_fast(), handles.
