* Support 2GB of memory on Malta systems with FreeBSD/mips.John Baldwin2018-06-281-0/+9
| | | | | | | | | | | | | | | When 2GB of memory is enabled for QEMU's Malta emulation, the physical memory ends at an address of 2^32 - 1. This causes an integer overflow to zero when computing the upper bound of the second phys_avail[] range. As a result, FreeBSD/mips kernels were only using the first 256MB of RAM and ignoring the remaining 1.75GB. To work around this, truncate the extended memory size to 2GB minus one page for 32-bit mips kernels.

* sys/mips: further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-2714-1/+29
| | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Notes: svn path=/head/; revision=326259

* Fix dump_avail[] for MALTA platforms to include the kernel.John Baldwin2016-12-221-1/+1
| | | | | | | | | | | | | | | | | | | | | | | dump_avail[] is supposed to be a superset of phys_avail[] that describes all of the memory ranges that should be included in a full dump. minidumps don't consider pages described by dump_avail[] to be valid and thus they are excluded via the is_dumpable() function. Most MIPS platforms (including MALTA) set dump_avail[] to be identical to phys_avail[]. In particular, phys_avail[] doesn't include the kernel itself, so pages for the kernel and it's global variables are not considered dumpable and not included in the dump. Fix this by setting dump_avail[0] to the first memory address (0) rather than the end of the kernel. Several other MIPS platforms have the same bug, though I am only able to test malta in qemu. The correct fix is to set dump_avail[] to describe RAM and in particular to not set dump_avail[0] to the end of the kernel (kernel_kseg0_end).

* Convert rman to use rman_res_t instead of u_longJustin Hibbits2016-01-273-4/+4
| | | | | | | | | | | | | | | | | | | | | | | Summary: Migrate to using the semi-opaque type rman_res_t to specify rman resources. For now, this is still compatible with u_long. This is step one in migrating rman to use uintmax_t for resources instead of u_long. Going forward, this could feasibly be used to specify architecture-specific definitions of resource ranges, rather than baking a specific integer type into the API. This change has been broken out to facilitate MFC'ing drivers back to 10 without breaking ABI.

| | | | | | | | | | | | | | | | | | | | | | | Extended memory here is "physical memory above 256MB". "memsize" in the environment only grows to 256MB; "ememsize" is the entire memory range.
