This speeds up boot a bit and also decreases binary size.
- Introduce a new CMake define ISAPNP_ENABLE that defined only in x86 platform
when ISA PnP is supported.
Rework the hardware support code to avoid unneeded transitions
between configuration states.
- Only call WaitForKey when needed.
- Each PnP state transition causes the bus to move to WaitForKey state.
Besides, deactivate logical device during processing remove request.
- Fix empty resource descriptors being created.
- Properly support IRQ descriptors.
- Introduce four helpers made to help search descriptors
in the logical device's requirements.
- Implement support for memory descriptors and alternative configurations.
- DMA descriptors are always DMA_8.
- Support all resource descriptors.
- Optimize card identification.
- Detect cards that is no longer present on the bus.
- Deactivate cards after the identification phase; they will be activated
by start device IRP.
- Provide a device description and compatible IDs to the device manager.
- Prevent duplicate IDs across multiple logical devices.
- Suppress warning about the usage of literals in port addresses.
- Implement device removal.
- Finish the Read Port special handling
introduced in 21514e473f.
- Gracefully handle low memory situations.
- Implement IRQ translator.
- Correctly stub power IRP handling.
- Remove unneeded dispatch routines; implement WMI IRP handling.
- Do not handle requests like WRITE_CONFIG.
- Add a signature member to device extensions to make checks clearer.
This PDO is created only once during start of first FDO.
Other buses will remain in an inactive state until
the first FDO receives a remove request.
CORE-17034
- Add SAL2 annotations.
- Use RTL_NUMBER_OF macro in kernel mode.
- Use better function/member names.
- Less hardcoded values.
- Add license information. See commit
d9face83c6 for details.
No functional changes.
Some virtual machines errorneously expose null PCI device function
on PIIX4 chipset where an USB controller should normally reside.
Windows pci.sys driver does not enumerate these devices.
Affected virtual machines:
- Connectix Virtual PC 5.1.370
- Connectix Virtual PC 5.2.418
- Microsoft Virtual PC 2004 SP1 (5.3.582.27)
- Microsoft Virtual PC 2007 SP1 (6.0.156.0)
Non-affected virtual machines:
- Connectix Virtual PC 4.0
- Microsoft Hyper-V
Fixes CORE-17636.
We must not do anything on PDO removal, especially not deleting it.
We are allowed to delete it, only once we successfully completed a IRP_MN_QUERY_DEVICE_RELATIONS without with PDO.
In ACPI resource descriptors, alternatives are marked with
StartDependent tags. Only the last set is terminated with EndDependent.
Therefore, since we only return the first alternative list for now,
ignore the first StartDependent tag and terminate enumeration at the second.
In the future we will need to build the full set of alternative lists here,
which will also make the unit test succeed fully.
This should fix random resource conflicts and make COM ports usable.
