thorpej | Liberally sprinkle static around to get more symbols out of the
global namespace. A small bit of const poisoning in the TC code.

Changes to make MPSAFE interrupts work on Alpha:
- Remove the ipl argument to scb_set() and the associated array of
"mpsafe" booleans initialized based on the ipl. It was bogus
anyway; all IPL_{BIO,NET,TTY}, etc. values are aliases of IPL_VM,
and for all practical purposes, there is really only one device
interrrupt level on Alpha anyway. Intead, we now treat all dispatches
from the SCB vector table as MP-safe, and it is now the handler for
that vector who is responsible for acquiring the KERNEL_LOCK if needed.
- Update the direct interrupt vector handlers in jensenio and TURBOchannel
to acquire the KERNEL_LOCK.
- Introduce a new ALPHA_INTR_MPSAFE flag, and add a flags argument to
alpha_shared_intr_establish(). When it is set, indicate that the
handler is MP-safe. Update alpha_shared_intr_dispatch() to pay
attention and acquire the KERNEL_LOCK (or not) as indicated.
- Re-factor all of the PCI interrupt handling, providing "generic PCI"
"PCI interrupts through ISA IRQs" implementations to significantly
reduce code duplication. Supplement the PCI chipset tag with more
info to facilitate this, and make the PCI interrupt-related routines
take a pci_chipset_tag_t argument rather than a void * argument.
- Because PCI interrupts on KN8AE are dispatched directly from the
SCB, provide a wrapper for non-MPSAFE interrupt handlers that
acquires the KERNEL_LOCK.
- Change the pci_intr_handle_t type to be a struct rather than an
integer type in order to catch any direct use of it as a value.
Add a set of functions to interact with pci_intr_handle_t, including
setting interrupt flags.
- Implement pci_intr_setattr() so that the PCI_INTR_MPSAFE attribute
can be set on a pci_intr_handle_t.
- While I'm here, make all of the MI PCI back-end operations call
through real functions rather than hopping directly through function
pointers in the chipset tag.
This change looks a lot bigger than it really is because of the re-factor
in the plethora of model-specific PCI interrupt back-ends. The KN8AE,
KN300, and T2/T3/T4 (Sable) are largely un-changed.

| 29-Mar-2014 |
christos | make pci_intr_string and eisa_intr_string take a buffer and a length
instead of relying in local static storage.
|
| 1.9 |
| 21-Mar-2014 |
christos | gc sprintf; reduce local static usage of interrupt strings that are only
used once for autoconf printing.

| 1.8 |
| 01-Jul-2011 |
dyoung | branches: 1.8.2; 1.8.12; 1.8.16;
#include <sys/bus.h> instead of <machine/bus.h>.
|
| 1.7 |
| 21-Nov-2009 |
rmind | - Use lwp_getpcb() on Alpha.
- Replace and clean struct user usage, slightly simplify some code parts.
- Include sys/user.h in MD proc.h .

| 28-Apr-2008 |
martin | Remove clause 3 and 4 from TNF licenses
|
| 1.5 |
| 07-Mar-2008 |
cube | branches: 1.5.2; 1.5.4;
Split the softc from the device_t for all lpt(4) variants and attachments
except the ppbus stuff (which doesn't compile) and ulpt(4) which is
unrelated and can be dealt with separately.
As usual, it comes with related cosmetic changes.

| 1.4 |
| 02-Oct-2002 |
thorpej | branches: 1.4.22; 1.4.84; 1.4.104; 1.4.108;
Use CFATTACH_DECL().
|
| 1.3 |
| 27-Sep-2002 |
thorpej | Declare all cfattach structures const.
|
| 1.2 |
| 27-Sep-2002 |
thorpej | Rather than referencing the cfdriver directly in the cfdata entries,
instead use a string naming the driver. The cfdriver is then looked
up in a list which is built at run-time.

| 1.1 |
| 21-Dec-2000 |
thorpej | branches: 1.1.2; 1.1.4; 1.1.6;
Add support for the AlphaServer 2100 (Sable) and the AlphaServer 2100A
(Lynx), written from scratch by me over a year ago, but never committed
to the tree because there was a bug I could never quite find. I have
fixed a few problems in the code, but still don't know if that bug is
quite fixed. Since I don't have access to the hardware directly, I'll
have to call for testers again.
