* syscalls.master: Add a new syscall type: RESERVEDBrooks Davis2021-01-261-8/+15

* Switch to the new device-tree vendor treeEmmanuel Vadot2021-01-152-6/+4
| | | | | | | | | | | | | The old vendor tree was never fully merged and doing partial merge isn't supported with git subtree merge so a new one was created. Switch the build to use the new DTS from sys/contrib/device-tree This also bump the DTS used to be in sync with Linux 5.9 While here change the way to get the linux version, simply hardcode the value in sys/dts/freebsd-compatible.dts and use awk to get that to put it in the CFLAGS. As a bonus we now have the bindings docs available in sys/contrib/device-tree/Bindings/ so no need to link to the Linux repo or to the vendor tree.
* sys/tools: Add a tool for generating arm and arm64 kernel images.Michal Meloun2020-12-301-0/+190
| | | | | | | | This tool can generate kernel images without changing the offsets in the final executable. It replaces the ELF header by properly sized zeroed block then emits a relative jump to _start(for 'v7jump' or 'v8jump' option) or the booti header (for 'v8booti' option) to the beginning of the converted file.

* Use a template assembly file for firmware object files.John Baldwin2020-12-171-2/+2
| | | | | | | | | | | | | | | | | | | | | Similar to r366897, this uses the .incbin directive to pull in a firmware file's contents into a .fwo file. The same scheme for computing symbol names from the filename is used as before to maximize compatiblity and not require rebuilding existing .fwo files for NO_CLEAN builds. Using ld -o binary requires extra hacks in linkers to either specify ABI options (e.g. soft- vs hard-float) or to ignore ABI incompatiblities when linking certain objects (e.g. object files with only data). Using the compiler driver avoids the need for these hacks as the compiler driver is able to set all the appropriate ABI options.

* Add NetBSD compatible bus_space_peek_N() and bus_space_poke_N() functions.Michal Meloun2020-09-191-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | One problem with the bus_space_read_N() and bus_space_write_N() family of functions is that they provide no protection against exceptions which can occur when no physical hardware or device responds to the read or write cycles. In such a situation, the system typically would panic due to a kernel-mode bus error. The bus_space_peek_N() and bus_space_poke_N() family of functions provide a mechanism to handle these exceptions gracefully without the risk of crashing the system. Typical example is access to PCI(e) configuration space in bus enumeration function on badly implemented PCI(e) root complexes (RK3399 or Neoverse N1 N1SDP and/or access to PCI(e) register when device is in deep sleep state. This commit adds a real implementation for arm64 only. The remaining architectures have bus_space_peek()/bus_space_poke() emulated by using bus_space_read()/bus_space_write() (without exception handling).

* makesyscalls.lua: improve syscall ordering validationKyle Evans2020-08-041-6/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There were two separate issues here: 1.) #if/#else wasn't taken into account at all for maxsyscall figures, but 2.) We didn't validate contiguous syscall numbers anyways... This kind of inconsistency is bad as we don't currently ensure explicit indexing of, e.g., the sysent array if one syscall is unimplemented/missing. This could be fixed and might be more robust, but it's also good to have the "documentation" that comes from being explicit as to what the missing syscalls are. The new version looks much like the awk version; stash off the current 'last highest syscall seen' if we hit an #if, restore to that if we hit an #else, and make sure that we're explicitly always defining the next syscall. The logic at the tail end of process_syscall_def that moves maxsyscall has been 'cleaned up' a little since we're now ensuring that it's monotonically increasing earlier in the function. At the moment I think it's unlikely we'd see range-definitions that are not UNIMPL, but there's no reason to specifically handle that case for bumping maxsyscall there. This change was provoked by reading the commit message for r363832 and realizing that this validation hadn't been included in the initial rewrite to lua.

| | | | | | | | | | | | | | | | | | | | | This currently requires a suitable lua + luafilesystem + luaposix from the ports tree to build. Discussion is underway in D21893 to add a suitable lua to the base system, cleverly disguised and out of the way of normal consumers. makesyscalls.sh is a good target for rewrite into lua as it's currently a sh+sed+awk script that can be difficult to add on to, at times. For instance, adding a new COMPAT* option (that mimicks the behaivor of most other COMPAT* options) requires a fairly substantial amount of copy/paste; see r352693 for instance. Attempts to generate part of the awk script for COMPAT* handling was (very kindly) rejected with a desire to just rewrite the script in a single language that can handle all of it.
