* - Overhaul the software interrupt code to use interrupt threads for eachjhb2000-10-251-11/+15
| | | | | | | | | | | | | | | | | | | type of software interrupt. Roughly, what used to be a bit in spending now maps to a swi thread. Each thread can have multiple handlers, just like a hardware interrupt thread. - Instead of using a bitmask of pending interrupts, we schedule the specific software interrupt thread to run, so spending, NSWI, and the shandlers array are no longer needed. We can now have an arbitrary number of software interrupt threads. When you register a software interrupt thread via sinthand_add(), you get back a struct intrhand that you pass to sched_swi() when you wish to schedule your swi thread to run. - Convert the name of 'struct intrec' to 'struct intrhand' as it is a bit more intuitive. Also, prefix all the members of struct intrhand with 'ih_'. - Make swi_net() a MI function since there is now no point in it being MD. Submitted by: cp

| | | | | | | | | | | - Make softinterrupts (SWI's) almost completely MI, and divorce them completely from the x86 hardware interrupt code. - The ihandlers array is now gone. Instead, there is a MI shandlers array that just contains SWI handlers. - Most of the former machine/ipl.h files have moved to a new sys/ipl.h. - Stub out all the spl*() functions on all architectures.

* Fix crashes on card eject for pccard modems. We check for NULL whenimp2000-03-111-12/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | we get the com address. If so, we go ahead and return. Bruce thinks there's a bug in the pccard layer that it terminates devices with extreme prejustice rather than letting them deside for themselves when to terminate (and he's likely right). This fix doesn't change that, but instead works around it by checking for NULL pointers at more places than before. The detach routine still calls functions at interrupt level that aren't reentrant. In theory this could cause a problem, but none showed up in practice. Future versions should correct this problem, likely by making the detach process a thread/process at the pccard level. NEWCARD will do this, and the current pccard layer should likely be modified to that as well, should it live long enough. A few style nits of the same form that were in my original patch sent off to bde were also fixed as part of this process. Mostly use of !ptr and return ENOPARENS. This should prevent a crash on suspend with an active ppp link as well, but that wasn't tested. Reviewed by: bde Approved by: jkh

* Fixed regressions in rev.1.274:bde2000-02-151-11/+15
| | | | | | | | | | | | | | | | 1) Non-AST4 multiport cards were broken by bypassing the code that changes `idev' to the multiport master device. 2) AST4 multiport cards apparently were broken by inverting the test for the master device having an irq. 3) Error handling for nonexistent master devices was broken by removing a check for a null pointer. 4) `int' error codes returned by bus_get_resource() were assigned directly to the boolean variable com->no_irq. Probably harmless, since the boolean is implemented as a u_char. Submitted by: part 1) by Chris Radek <cradek@in221.inetnebr.com> part 2) by yokota Approved by: jkh

In this incarnation of the pccard things, we map the disable the slot action to detach the driver, which removes the driver from the device tree. When that is done, a panic would soon follow as the ifconfig tried to down the device. Didn't fix: o Should cache the pccard dev child's pointer in struct slot o remove now unused parts of struct slot o Any driver using softc after detach has been called. sio's softc used to be statically allocated, so you could check sc->gone, but that is now gone. o Didn't remove gone from softc of drivers that use the old pccard method.
