This section is just a reminder that + drivers need to indicate DMA capabilities of the device and is not + an authoritative source for DMA interfaces. ] + +While all drivers should explicitly indicate the DMA capability +(e.g. 32 or 64 bit) of the PCI bus master, devices with more than +32-bit bus master capability for streaming data need the driver +to "register" this capability by calling pci_set_dma_mask() with +appropriate parameters. In general this allows more efficient DMA +on systems where System RAM exists above 4G _physical_ address. + +Drivers for all PCI-X and PCIe compliant devices must call +pci_set_dma_mask() as they are 64-bit DMA devices. + +Similarly, drivers must also "register" this capability if the device +can directly address "consistent memory" in System RAM above 4G physical +address by calling pci_set_consistent_dma_mask(). +Again, this includes drivers for all PCI-X and PCIe compliant devices. +Many 64-bit "PCI" devices (before PCI-X) and some PCI-X devices are +64-bit DMA capable for payload ("streaming") data but not control +("consistent") data. + + +3.4 Setup shared control data +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +Once the DMA masks are set, the driver can allocate "consistent" (a.k.a. shared) +memory. See Documentation/DMA-API.txt for a full description of +the DMA APIs. This section is just a reminder that it needs to be done +before enabling DMA on the device. + + +3.5 Initialize device registers +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +Some drivers will need specific "capability" fields programmed +or other "vendor specific" register initialized or reset. +E.g. clearing pending interrupts. + + +3.6 Register IRQ handler +~~~~~~~~~~~~~~~~~~~~~~~~ +While calling request_irq() is the the last step described here, +this is often just another intermediate step to initialize a device. +This step can often be deferred until the device is opened for use. + +All interrupt handlers for IRQ lines should be registered with IRQF_SHARED +and use the devid to map IRQs to devices (remember that all PCI IRQ lines +can be shared). + +request_irq() will associate an interrupt handler and device handle +with an interrupt number. Historically interrupt numbers represent +IRQ lines which run from the PCI device to the Interrupt controller. +With MSI and MSI-X (more below) the interrupt number is a CPU "vector". + +request_irq() also enables the interrupt. Make sure the device is +quiesced and does not have any interrupts pending before registering +the interrupt handler. + +MSI and MSI-X are PCI capabilities. Both are "Message Signaled Interrupts" +which deliver interrupts to the CPU via a DMA write to a Local APIC. +The fundamental difference between MSI and MSI-X is how multiple +"vectors" get allocated. MSI requires contiguous blocks of vectors +while MSI-X can allocate several individual ones. + +MSI capability can be enabled by calling pci_enable_msi() or +pci_enable_msix() before calling request_irq(). This causes +the PCI support to program CPU vector data into the PCI device +capability registers. + +If your PCI device supports both, try to enable MSI-X first. +Only one can be enabled at a time. Many architectures, chip-sets, +or BIOSes do NOT support MSI or MSI-X and the call to pci_enable_msi/msix +will fail. This is important to note since many drivers have +two (or more) interrupt handlers: one for MSI/MSI-X and another for IRQs. +They choose which handler to register with request_irq() based on the +return value from pci_enable_msi/msix(). + +There are (at least) two really good reasons for using MSI: +1) MSI is an exclusive interrupt vector by definition. + This means the interrupt handler doesn't have to verify + its device caused the interrupt. + +2) MSI avoids DMA/IRQ race conditions. DMA to host memory is guaranteed + to be visible to the host CPU(s) when the MSI is delivered. This + is important for both data coherency and avoiding stale control data. + This guarantee allows the driver to omit MMIO reads to flush + the DMA stream. + +See drivers/infiniband/hw/mthca/ or drivers/net/tg3.c for examples +of MSI/MSI-X usage. + + + +4. PCI device shutdown +~~~~~~~~~~~~~~~~~~~~~~~ + +When a PCI device driver is being unloaded, most of the following +steps need to be performed: + + Disable the device from generating IRQs + Release the IRQ (free_irq()) + Stop all DMA activity + Release DMA buffers (both streaming and consistent) + Unregister from other subsystems (e.g. scsi or netdev) + Disable device from responding to MMIO/IO Port addresses + Release MMIO/IO Port resource(s) + + +4.1 Stop IRQs on the device +~~~~~~~~~~~~~~~~~~~~~~~~~~~ +How to do this is chip/device specific. If it's not done, it opens +the possibility of a "screaming interrupt" if (and only if) +the IRQ is shared with another device. + +When the shared IRQ handler is "unhooked", the remaining devices +using the same IRQ line will still need the IRQ enabled. Thus if the +"unhooked" device asserts IRQ line, the system will respond assuming +it was one of the remaining devices asserted the IRQ line. Since none +of the other devices will handle the IRQ, the system will "hang" until +it decides the IRQ isn't going to get handled and masks the IRQ (100,000 +iterations later). Once the shared IRQ is masked, the remaining devices +will stop functioning properly. Not a nice situation. + +This is another reason to use MSI or MSI-X if it's available. +MSI and MSI-X are defined to be exclusive interrupts and thus +are not susceptible to the "screaming interrupt" problem. + + +4.2 Release the IRQ +~~~~~~~~~~~~~~~~~~~ +Once the device is quiesced (no more IRQs), one can call free_irq(). +This function will return control once any pending IRQs are handled, +"unhook" the drivers IRQ handler from that IRQ, and finally release +the IRQ if no one else is using it. + + +4.3 Stop all DMA activity +~~~~~~~~~~~~~~~~~~~~~~~~~ +It's extremely important to stop all DMA operations BEFORE attempting +to deallocate DMA control data. Failure to do so can result in memory +corruption, hangs, and on some chip-sets a hard crash. -4. How to access PCI config space +Stopping DMA after stopping the IRQs can avoid races where the +IRQ handler might restart DMA engines. + +While this step sounds obvious and trivial, several "mature" drivers +didn't get this step right in the past. + + +4.4 Release DMA buffers +~~~~~~~~~~~~~~~~~~~~~~~ +Once DMA is stopped, clean up streaming DMA first. +I.e. unmap data buffers and return buffers to "upstream" +owners if there is one. + +Then clean up "consistent" buffers which contain the control data. + +See Documentation/DMA-API.txt for details on unmapping interfaces. + + +4.5 Unregister from other subsystems +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +Most low level PCI device drivers support some other subsystem +like USB, ALSA, SCSI, NetDev, Infiniband, etc. Make sure your +driver isn't losing resources from that other subsystem. +If this happens, typically the symptom is an Oops (panic) when +the subsystem attempts to call into a driver that has been unloaded. + + +4.6 Disable Device from responding to MMIO/IO Port addresses +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +io_unmap() MMIO or IO Port resources and then call pci_disable_device(). +This is the symmetric opposite of pci_enable_device(). +Do not access device registers after calling pci_disable_device(). + + +4.7 Release MMIO/IO Port Resource(s) +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +Call pci_release_region() to mark the MMIO or IO Port range as available. +Failure to do so usually results in the inability to reload the driver. + + + +5.

I/O Port space is only 64KB on Intel Architecture[1] and is +likely also fragmented since the I/O base register of PCI-to-PCI +bridge will usually be aligned to a 4KB boundary[2]. On such systems, +pci_enable_device() and pci_request_region() will fail when +attempting to enable I/O Port regions that don't have I/O Port +resources assigned. + +Fortunately, many PCI devices which request I/O Port resources also +provide access to the same registers via MMIO BARs. These devices can +be handled without using I/O port space and the drivers typically +offer a CONFIG_ option to only use MMIO regions +(e.g. CONFIG_TULIP_MMIO). PCI devices typically provide I/O port +interface for legacy OSes and will work when I/O port resources are not +assigned. The "PCI Local Bus Specification Revision 3.0" discusses +this on p.44, "IMPLEMENTATION NOTE". + +If your PCI device driver doesn't need I/O port resources assigned to +I/O Port BARs, you should use pci_enable_device_bars() instead of +pci_enable_device() in order not to enable I/O port regions for the +corresponding devices. In addition, you should use +pci_request_selected_regions() and pci_release_selected_regions() +instead of pci_request_regions()/pci_release_regions() in order not to +request/release I/O port regions for the corresponding devices. + +[1] Some systems support 64KB I/O port space per PCI segment. +[2] Some PCI-to-PCI bridges support optional 1KB aligned I/O base. + + + +11. MMIO Space and "Write Posting" +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Converting a driver from using I/O Port space to using MMIO space +often requires some additional changes. Specifically, "write posting" +needs to be handled. Many drivers (e.g. tg3, acenic, sym53c8xx_2) +already do this. I/O Port space guarantees write transactions reach the PCI +device before the CPU can continue. Writes to MMIO space allow the CPU +to continue before the transaction reaches the PCI device.
