kernel will panic if an USB keyboard is plugged later.
Of course there will be a problem on a desktop machine with an USB attached
keyboard, but that cannot be fixed without access to such a machine..
* Restore the signal mask with sigprocmask() instead of _UC_SIGMASK,
* since libpthread may want to interpose on signal handling.
Fixes regress/lib/libpthread/siglongjmp1.
CSR separately (and now from the correctly sized __fpregset_t). The
FP CSR is copied separately to avoid endianness/alignment issues.
Part of fix for PR port-mips/25942. Thanks to Christos Zoulas and
Klaus Klein for help with debugging this.
This areas is called the comm pages. It is used to provide fast access to
several data and functions.
The comm pages are mapped starting at 0xffff800 (address chosed so that
absolute branch can be used, so it can be accessed even when dynamic linking
is not ready). NetBSD has the user stack here, so we need to provide a
Darwin-specific stack setup routine which sets the top of the stack at
0xbfff0000.
This implementation is not complete but it does enough to get MacOS X.3
starting again (static binaries run, dynamic binaries still have an issue).
in the comm pages functions, we only implement bcopy, pthread_self and
memcpy.
TODO:
- clean up the powerpc specific code from MD parts
- for now we map only one page to avoid a crash, we want two pages.
- write all the comm functions.
Not reading the mii media status if the interface isn't up doesn't hurt,
as the real media status isn't reported if the interface isn't up anyway
(checked on i386).
On my alpha500, I tracked down the machine check to the GO_WINDOW(4) at
line 1858 of elinkxl.c. It's possible that the problem which was fixed in
rev 1.72 was also the GO_WINDOW(4) used in the non-mii case. tr from ddb
and a single-step show different results, and I trust the single-step
one :)
It is a layer to make it possible to have loadable PCI device drivers.
First you load (with symbols) the pcilkm module, then you can load PCI
drivers that have been compiled to work with pcilkm.
Two examples are provided. 'pcienum', the first one, is a simple
demonstration of how to use pcilkm: it is the basic skeleton of a PCI
driver, and will attach at load time to all PCI devices known to the
system.
The second example 'auich' demonstrates how simple it is to use an
existing driver as a LKM. It simply includes the code for auich(4) and
then adds the necessary pcilkm logic. However there are some drawbacks
that are described in the README file.
