- add option SDL which pulls in thunk_sdl code and links the kernel to libSDL
- add an experimental framebuffer driver based on thunk_sdl, enable with:
options SDL
genfb* at mainbus?
wsdisplay* at genfb?
options WS_KERNEL_FG=WSCOL_GREEN
options WSEMUL_VT100
- reserve a major # for wsdisplay
- add thunk_getenv()

prematurely in case they do, to avoid looping "endlessly" (or at least
a very long time) at IPL_BIO while trying to handle requests.
This should not happen in a nominal scenario, but the ring can get
corrupted for whatever reason (memory errors, domU failures or
exploitation).
available in the devs array. Change the type of the devs array from
char to uint8_t. Treat the return value of pci_bus_devorder() as the
number of slots that it filled.
Don't use the __PCI_BUS_DEVORDER #definition to configure the kernel
but let the linker do it. Make pci_bus_devorder() available on all
architectures by adding a default implementation that will DTRT on
all architectures but hpcmips, the only architecture to #define
__PCI_BUS_DEVORDER. On hpcmips, adapt the implementation to the new
calling convention.
XXX I can compile an hpcmips GENERIC kernel, but I don't have a
XXX hpcmips box to test it on.
table can address can be larger than the amount of address space the CPU
implementation supports. This change limits the amount address space to what
the CPU implementation provides.
to VM_MAXUSER_ADDRESS and KVM is above that.
Note that the userspace is surrounded by a configurable amount of
non-accessible barrier space to prevent accidental out-of-boundaries access
even when reading.
address in a vmem(9) arena, 0) and VMEM_ADDR_MAX (the maximum possible
address, currently 0xFFFFFFFF). Modify several boundary conditions so
that a vmem(9) arena can allocate ranges including VMEM_ADDR_MAX.
Update documentation and tests.
These changes pass the tests in sys/kern/subr_vmem.c. To compile the
and run the test program, run "cd sys/kern/ && gcc -DVMEM_SANITY -o
subr_vmem ./subr_vmem.c && ./subr_vmem".
