- Add PCI Extended Configuration Space support into x86.
- Check register offset of pci_conf_read() in MD part. It returns (pcireg_t)-1
if it isn't accessible.
- Decode Extended Capability in PCI Extended Configuration Space.
Currently the following extended capabilities are decoded:
- Advanced Error Reporting
- Virtual Channel
- Device Serial Number
- Power Budgeting
- Root Complex Link Declaration
- Root Complex Event Collector Association
- Access Control Services
- Alternative Routing-ID Interpretation
- Address Translation Services
- Single Root IO Virtualization
- Page Request
- TPH Requester
- Latency Tolerance Reporting
- Secondary PCI Express
- Process Address Space ID
- LN Requester
- L1 PM Substates
The following extended capabilities are not decoded yet:
- Root Complex Internal Link Control
- Multi-Function Virtual Channel
- RCRB Header
- Vendor Unique
- Configuration Access Correction
- Multiple Root IO Virtualization
- Multicast
- Resizable BAR
- Dynamic Power Allocation
- Protocol Multiplexing
- Downstream Port Containment
- Precision Time Management
- M-PCIe
- Function Reading Status Queueing
- Readiness Time Reporting
- Designated Vendor-Specific
avoid calling the "_DIS" method during acpi interrupt link setup,
which hangs various nforce4 based motherboards.
when the problem is properly fixed, remove this hack. for now,
it allows someone (me) to have a valid kernel config that doesn't
require a source hack every new tree.
ok chs@
On one of my machines, there's no _GPE method, so
acpiec_parse_gpe_package fails, and the only function acpiec(4)
serves is to inhibit suspend/resume.
XXX We should really put the power handlers in the cfattach so that
it's not necessary to register a null power handler in every error
branch of every device's attach routine...
The four modules are apple_smc for the core functions, apple_smc_acpi
for attachment at acpi, and apple_smc_fan & apple_smc_temp for stuff
on the SMC.
Seems like there's a lot more bookkeeping necessary to maintain
children of an applesmc device implemented by loadable modules.
Maybe there's a better way I just haven't figured out yet.
Device interface derived by reading the Linux driver source code and
<http:///www.parhelia.ch/blog/statics/k3_keys.html> as of 2012-12-05.
Includes support for attaching fan and temperature sensors to sysmon.
No accelerometer yet.
Compile-tested only, based on some run-testing of experiments from
userland. Module attachment is not quite finished, so it won't work
yet.
this fixes PCI interrupts on some systems (eg. HP XW9400) and we suspect that
the problems which led to the original change were caused by buggy early
implementations of ACPI, which are now ignored by date.
