- replace rtk_type member in rtk_softc which has chip types
with new rtk_quirk that represents quirks on each chip:
- RTKQ_8129 doesn't have internal MII (used in rtk(4))
- RTKQ_8139CPLUS has different register layout (for re(4))
- RTKQ_8169NONS (original 8169) requires some settings on init
- RTKQ_PCIE requires different settings in setmulti
so that we don't have to check each hwrev values or types everywhere
and newer variants will also work without changes if they don't
have other quirks
(sc_rev is unchenged for now for reference to the Realtek's driver)
- don't check hwrev register in re_pci_match() but check
only PCI_VENDER(), PCI_PRODUCT() and PCI_REVISION()
so that we no longer have to map pci space there
- add a new HWREV value for another 8168 variant
- try to map PCI mem space more properly
- remove (probably unneeded) ifp->if_baudrate initialization
Tested on a newer 8168 variant by Dennis den Brok on tech-kern,
and also tested on 8139 and 8169C on macppc, and 8139C+ on landisk
by me.
associated with this, 0, the nvram device, and now 1, the residual
device. The devices allow the user to directly read the contents of the
kernel copy of the nvram, and the residual data respectively. There is
no provision for write.
increase ifi_noproto. If the GRE header contains routing options,
increase the input-error count, ifi_ierrors.
While I am here, make some cosmetic changes: remove unnecessary
'proto' argument from gre_input3(). Shorten some staircases.
actually contains entries. It is apparently possible to get a non-null,
but empty dictionary back. This seems to happen if you inject a ppb-card
on pci0 when you also have a prep pci1 at a later device function. With
this, my fxp card works in any slot on my 7043-140.
the mutex that the waiters are using to synchronise, then transfer them
to the mutex's waiters list so that the wakeup is deferred until release
of the mutex. Improves the timings for CV sleep/wakeup by between 30-100%
in tests conducted locally on a UP system. There can be a penalty for MP
systems when only one thread is being awoken, but in practice I think it
won't be be an issue.
- pthread_signal: search for a thread that does not have a pending wakeup.
Threads can have a pending wakeup and still be on the waiters list if we
clash with an earlier pthread_cond_broadcast().
be used only as as a hint. Clear the pointer when releasing the mutex.
- When releasing a mutex, wake all waiters. Makes it possible to tranfer
waiters from another object to a mutex.
- Don't bother sorting the sleep queues, since user space controls the
order of removal.
- Change setrunnable(t) to lwp_unsleep(t). No functional change from the
perspective of user applications.
- Minor cosmetic changes.
Modulation.
This works by changing the duty cycle of the clock modulation,
and saves power and helps to not increase the temperature by
software.
Adapted from OpenBSD/FreeBSD's p4tcc.
To enable it one must use "options INTEL_ONDEMAND_CLOCKMOD".
Tested by me in UP and SMP, ok'ed by Matthew R. Green.
in all CPUs available in the system. This adds another member
to struct cpu_info, ci_msr_rvalue; it will contain the value of the MSR
in a previous operation.
Tested with clockmod in UP and SMP by me, tested with est in SMP
by Daniel Carosone and Michael Van Elst.

Minor modifications by me:
-use an mi device major number
-(coarsly) divided into pci card specific and less specific parts, moved
the latter to dev/drm
-renamed autoconf attributes to reflect this
Todo:
-adapt all card frontends but i915 to drm include file location
-review the mtrr change
-make the change to agp_i810.c coexist with the fix for buggy VESA
BIOSes which is commented out temporarily
-RCS IDs etc style stuff
-LKM support (rescan support for vga)
-test
