2014-09-20On i386, agp_map_subregion might sleep, which is not allowed in some ofMark Kettenis
the inteldrm code. Fix this by adding new interfaces that can map a single page without sleeping and use that in the execbuffer fast path that needs this "atomic" behaviour. Should fix the panic I've seen under memory pressure on i386.

so remove the former and include the latter instead of pulling it in <dev/pci/agpvar.h>. This header already requires various other types anyway. While here remove unneeded headers.

2013-12-06Add a DVACT_WAKEUP op to the *_activate() API. This is called after theTheo de Raadt
kernel resumes normal (non-cold, able to run processes, etc) operation. Previously we were relying on specific DVACT_RESUME op's in drivers creating callback/threads themselves, but that has become too common, indicating the need for a built-in mechanism. ok dlg kettenis, tested by a sufficient amount of people

2013-11-06Add support for Power Resources for Dx states and the necessary hookMartin Pieuchot
for PCI devices. This hook should be called twice, before and after changing the power state of a PCI device. Before setting the device to the new state, the ACPI layer will notify every power resources linked to the device for that state and make sure they are turned "_ON". After changing the state of the device, it will decrement the reference of every power resources linked to that device for the old state and turn them "_OFF" if they are no longer referenced. This fixes the no-USB after resume problem seen on various ThinkPad, problem initialy diagnosed with Alexander Polakov. ok kettenis@, deraadt@

2013-07-10To prevent lock ordering problems with the kernel lock, we need to make sureMark Kettenis
we block all interrupts that can grab the kernel lock. The simplest way to achieve this is to make sure mutexes always raise the ipl to the highest level that has interrupts that grab the kernel lock. This will allow us to have "mpsafe" interrupt handlers at lower priority levels. No change for non-MULTIPROCESSOR kernels. ok matthew@
2013-05-30If ACPI is not compiled in, pci_min_powerstate() has no facts to supportTheo de Raadt
is should return D3. It should return the current power state. ok kettenis mlarkin
2013-05-30Enforce ca_activate tree-walks over the entire heirarchy for all events,Theo de Raadt
cleaning up some shutdown-hook related code on the way. (A few drivers related to sparc are still skipped at kettenis' request) ok kettenis mlarkin, tested by many others too
2013-05-16Implement a mechanism to establish interrupt handlers that don't grab theMark Kettenis
kernel lock upon entry through a new IPL_MPSAFE flag/level.
2013-03-17Add an interface to rebind AGP DMA mappings. To be used by the upcoming KMSMark Kettenis
support to reload bindings after suspend/resume and to update cachability flags in the address translation table entries.

2012-10-17Swap arguments to wdog_register() since it is nicer, and prepareTheo de Raadt
wdog_shutdown() for external usage.
2012-10-08Revamp the sequences for suspend/hibernate -> resume so that the codeTheo de Raadt
paths are reflexive. It is now possible to fail part-way through a suspend sequence, and recover along the resume code path. Split DVACT_SUSPEND by adding a new DVACT_POWERDOWN method is used after hibernate (and suspend too) to finish the job. Some drivers must be converted at the same time to use this instead of shutdown hooks (the others will follow at a later time) ok kettenis mlarkin

2011-10-13I'm sick and tired of people doing misalgned reads and writes to PCI configMark Kettenis
space and not noticing because they only test on amd64. So enforce alignment there as well, at least for a little while such that we find those bugs and force people to fix them.
2011-10-10Introduce pci_probe_device_hook(pci_chipset_tag_t, struct pci_attach_args *).Miod Vallat
This mandatory function will get invoked in pci_probe_device(), and allows a pci host driver to alter the pci_attach_args passed to a device when attaching. This function will also, if returning non-zero, cause the device to be skipped completely during all the phases of the PCI device discovery (i.e. ressource enumeration, ressource assignment, and actual attachment). This particular feature is experimental and might be reverted in the future (or the scope narrowed to device attachment only). A dummy #define pci_probe_device_hook() 0 is added to all platforms except sgi, where real functions (currently only returning 0) are added; real meat will be added shortly. Discussed at s2k11, no objection from the usual suspects.

2011-05-30Enable MSI on selected hardware. For now this means:Mark Kettenis
- Intel chipset supporting Pentium 4 or later. - Any AMD chipset made in this century. - Any NVIDIA chipset that has PCIe. Explicitly disable MSI on chipsets that connect to the CPU over HyperTransport. Enabling MSI on those systems is handled by the HyperTransport support code in our PCI subsystem.

2011-05-21First stab at supporting Message Signaled Interrupts on i386. Still work inMark Kettenis
progress. The code is effectively disabled as long as PCI_FLAGS_MSI_ENABLED doesn't get set for the root PCI bus.
2011-04-22Stop printing the PCI interrupt line programmed by the BIOS for APICMark Kettenis
