14 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~ | 30 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~ |
15 | There exist two kinds of PCI drivers: new-style ones (which leave most of | 31 | PCI drivers "discover" PCI devices in a system via pci_register_driver(). |
16 | probing for devices to the PCI layer and support online insertion and removal | 32 | Actually, it's the other way around. When the PCI generic code discovers |
17 | of devices [thus supporting PCI, hot-pluggable PCI and CardBus in a single | 33 | a new device, the driver with a matching "description" will be notified. |
18 | driver]) and old-style ones which just do all the probing themselves. Unless | 34 | Details on this below. |
19 | you have a very good reason to do so, please don't use the old way of probing | 35 | |
20 | in any new code. After the driver finds the devices it wishes to operate | 36 | pci_register_driver() leaves most of the probing for devices to |
21 | on (either the old or the new way), it needs to perform the following steps: | 37 | the PCI layer and supports online insertion/removal of devices [thus |
38 | supporting hot-pluggable PCI, CardBus, and Express-Card in a single driver]. | ||
39 | pci_register_driver() call requires passing in a table of function | ||
40 | pointers and thus dictates the high level structure of a driver. | ||
41 | |||
42 | Once the driver knows about a PCI device and takes ownership, the | ||
43 | driver generally needs to perform the following initialization: | ||
22 | 44 | ||
23 | Enable the device | 45 | Enable the device |
24 | Access device configuration space | 46 | Request MMIO/IOP resources |
25 | Discover resources (addresses and IRQ numbers) provided by the device | 47 | Set the DMA mask size (for both coherent and streaming DMA) |
26 | Allocate these resources | 48 | Allocate and initialize shared control data (pci_allocate_coherent()) |
27 | Communicate with the device | 49 | Access device configuration space (if needed) |
50 | Register IRQ handler (request_irq()) | ||
51 | Initialize non-PCI (i.e. LAN/SCSI/etc parts of the chip) | ||
52 | Enable DMA/processing engines | ||
53 | |||
54 | When done using the device, and perhaps the module needs to be unloaded, | ||
55 | the driver needs to take the follow steps: | ||
56 | Disable the device from generating IRQs | ||
57 | Release the IRQ (free_irq()) | ||
58 | Stop all DMA activity | ||
59 | Release DMA buffers (both streaming and coherent) | ||
60 | Unregister from other subsystems (e.g. scsi or netdev) | ||
61 | Release MMIO/IOP resources | ||

219 | 2. How to find PCI devices manually | ||
220 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | ||
221 | |||
222 | PCI drivers should have a really good reason for not using the | ||
223 | pci_register_driver() interface to search for PCI devices. | ||
224 | The main reason PCI devices are controlled by multiple drivers | ||
225 | is because one PCI device implements several different HW services. | ||
226 | E.g. combined serial/parallel port/floppy controller. | ||

163 | 252 | ||
164 | 3. Enabling and disabling devices | ||
165 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | ||
166 | Before you do anything with the device you've found, you need to enable | ||
167 | it by calling pci_enable_device() which enables I/O and memory regions of | ||
168 | the device, allocates an IRQ if necessary, assigns missing resources if | ||
169 | needed and wakes up the device if it was in suspended state. Please note | ||
170 | that this function can fail. | ||
171 | 253 | ||
172 | If you want to use the device in bus mastering mode, call pci_set_master() | 254 | 3. Device Initialization Steps |
173 | which enables the bus master bit in PCI_COMMAND register and also fixes | 255 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ |
174 | the latency timer value if it's set to something bogus by the BIOS. | 256 | |
257 | As noted in the introduction, most PCI drivers need the following steps | ||
258 | for device initialization: | ||
175 | 259 | ||
176 | If you want to use the PCI Memory-Write-Invalidate transaction, | 260 | Enable the device |
261 | Request MMIO/IOP resources | ||
262 | Set the DMA mask size (for both coherent and streaming DMA) | ||
263 | Allocate and initialize shared control data (pci_allocate_coherent()) | ||
264 | Access device configuration space (if needed) | ||
265 | Register IRQ handler (request_irq()) | ||
266 | Initialize non-PCI (i.e. LAN/SCSI/etc parts of the chip) | ||
267 | Enable DMA/processing engines. | ||
268 | |||
269 | The driver can access PCI config space registers at any time. | ||
270 | (Well, almost. When running BIST, config space can go away...but | ||
271 | that will just result in a PCI Bus Master Abort and config reads | ||
272 | will return garbage). | ||
273 | |||
274 | |||
275 | 3.1 Enable the PCI device | ||
276 | ~~~~~~~~~~~~~~~~~~~~~~~~~ | ||
277 | Before touching any device registers, the driver needs to enable | ||
278 | the PCI device by calling pci_enable_device(). This will: | ||
279 | o wake up the device if it was in suspended state, | ||
280 | o allocate I/O and memory regions of the device (if BIOS did not), | ||
281 | o allocate an IRQ (if BIOS did not). | ||
282 | |||
283 | NOTE: pci_enable_device() can fail! Check the return value. | ||
284 | NOTE2: Also see pci_enable_device_bars() below. Drivers can | ||
285 | attempt to enable only a subset of BARs they need. | ||
286 | |||
287 | [ OS BUG: we don't check resource allocations before enabling those | ||
288 | resources. The sequence would make more sense if we called | ||
289 | pci_request_resources() before calling pci_enable_device(). | ||
290 | Currently, the device drivers can't detect the bug when when two | ||
291 | devices have been allocated the same range. This is not a common | ||
292 | problem and unlikely to get fixed soon. | ||
293 | |||
294 | This has been discussed before but not changed as of 2.6.19: | ||
295 | http://lkml.org/lkml/2006/3/2/194 | ||

297 | |||
298 | pci_set_master() will enable DMA by setting the bus master bit | ||
299 | in the PCI_COMMAND register. It also fixes the latency timer value if | ||
300 | it's set to something bogus by the BIOS. | ||

177 | call pci_set_mwi(). This enables the PCI_COMMAND bit for Mem-Wr-Inval | 303 | call pci_set_mwi(). This enables the PCI_COMMAND bit for Mem-Wr-Inval |

180 | may support Memory-Write-Invalidate. | 306 | or chip-sets may support Memory-Write-Invalidate. |
307 | |||
308 | |||
309 | 3.2 Request MMIO/IOP resources | ||
310 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | ||
311 | Memory (MMIO), and I/O port addresses should NOT be read directly | ||
312 | from the PCI device config space. Use the values in the pci_dev structure | ||
313 | as the PCI "bus address" might have been remapped to a "host physical" | ||
314 | address by the arch/chip-set specific kernel support. | ||
181 | 315 | ||
182 | If your driver decides to stop using the device (e.g., there was an | 316 | See Documentation/IO-mapping.txt for how to access device registers |
183 | error while setting it up or the driver module is being unloaded), it | 317 | or device memory. |
184 | should call pci_disable_device() to deallocate any IRQ resources, disable | 318 | |
185 | PCI bus-mastering, etc. You should not do anything with the device after | 319 | The device driver needs to call pci_request_region() to verify |
320 | no other device is already using the same address resource. | ||
321 | Conversely, drivers should call pci_release_region() AFTER | ||
186 | calling pci_disable_device(). | 322 | calling pci_disable_device(). |
323 | The idea is to prevent two devices colliding on the same address range. | ||
324 | |||
325 | [ See OS BUG comment above. Currently (2.6.19), The driver can only | ||
326 | determine MMIO and IO Port resource availability _after_ calling | ||
327 | pci_enable_device(). ] | ||
328 | |||
329 | Generic flavors of pci_request_region() are request_mem_region() | ||
330 | (for MMIO ranges) and request_region() (for IO Port ranges). | ||
331 | Use these for address resources that are not described by "normal" PCI | ||
332 | BARs. | ||
333 | |||
334 | Also see pci_request_selected_regions() below. | ||
335 | |||
336 | |||
337 | 3.3 Set the DMA mask size | ||
338 | ~~~~~~~~~~~~~~~~~~~~~~~~~ | ||
339 | [ If anything below doesn't make sense, please refer to | ||
340 | Documentation/DMA-API.txt. This section is just a reminder that | ||
341 | drivers need to indicate DMA capabilities of the device and is not | ||
342 | an authoritative source for DMA interfaces. ] | ||
343 | |||
344 | While all drivers should explicitly indicate the DMA capability | ||
345 | (e.g. 32 or 64 bit) of the PCI bus master, devices with more than | ||
346 | 32-bit bus master capability for streaming data need the driver | ||
347 | to "register" this capability by calling pci_set_dma_mask() with | ||
348 | appropriate parameters. In general this allows more efficient DMA | ||
349 | on systems where System RAM exists above 4G _physical_ address. | ||
350 | |||
351 | Drivers for all PCI-X and PCIe compliant devices must call | ||
352 | pci_set_dma_mask() as they are 64-bit DMA devices. | ||
353 | |||
354 | Similarly, drivers must also "register" this capability if the device | ||
355 | can directly address "consistent memory" in System RAM above 4G physical | ||
356 | address by calling pci_set_consistent_dma_mask(). | ||
357 | Again, this includes drivers for all PCI-X and PCIe compliant devices. | ||
358 | Many 64-bit "PCI" devices (before PCI-X) and some PCI-X devices are | ||
359 | 64-bit DMA capable for payload ("streaming") data but not control | ||
360 | ("consistent") data. | ||
361 | |||
362 | |||
363 | 3.4 Setup shared control data | ||
364 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | ||
365 | Once the DMA masks are set, the driver can allocate "consistent" (a.k.a. shared) | ||
366 | memory. See Documentation/DMA-API.txt for a full description of | ||
367 | the DMA APIs. This section is just a reminder that it needs to be done | ||
368 | before enabling DMA on the device. | ||
369 | |||
370 | |||
371 | 3.5 Initialize device registers | ||
372 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | ||
373 | Some drivers will need specific "capability" fields programmed | ||
374 | or other "vendor specific" register initialized or reset. | ||
375 | E.g. clearing pending interrupts. | ||
376 | |||
377 | |||
378 | 3.6 Register IRQ handler | ||
379 | ~~~~~~~~~~~~~~~~~~~~~~~~ | ||
380 | While calling request_irq() is the the last step described here, | ||
381 | this is often just another intermediate step to initialize a device. | ||
382 | This step can often be deferred until the device is opened for use. | ||
383 | |||
384 | All interrupt handlers for IRQ lines should be registered with IRQF_SHARED | ||
385 | and use the devid to map IRQs to devices (remember that all PCI IRQ lines | ||
386 | can be shared). | ||
387 | |||
388 | request_irq() will associate an interrupt handler and device handle | ||
389 | with an interrupt number. Historically interrupt numbers represent | ||
390 | IRQ lines which run from the PCI device to the Interrupt controller. | ||
391 | With MSI and MSI-X (more below) the interrupt number is a CPU "vector". | ||
392 | |||
393 | request_irq() also enables the interrupt. Make sure the device is | ||
394 | quiesced and does not have any interrupts pending before registering | ||
395 | the interrupt handler. | ||
396 | |||
397 | MSI and MSI-X are PCI capabilities. Both are "Message Signaled Interrupts" | ||
398 | which deliver interrupts to the CPU via a DMA write to a Local APIC. | ||
399 | The fundamental difference between MSI and MSI-X is how multiple | ||
400 | "vectors" get allocated. MSI requires contiguous blocks of vectors | ||
401 | while MSI-X can allocate several individual ones. | ||
402 | |||
403 | MSI capability can be enabled by calling pci_enable_msi() or | ||
404 | pci_enable_msix() before calling request_irq(). This causes | ||
405 | the PCI support to program CPU vector data into the PCI device | ||
406 | capability registers. | ||
407 | |||
408 | If your PCI device supports both, try to enable MSI-X first. | ||
409 | Only one can be enabled at a time. Many architectures, chip-sets, | ||
410 | or BIOSes do NOT support MSI or MSI-X and the call to pci_enable_msi/msix | ||
411 | will fail. This is important to note since many drivers have | ||
412 | two (or more) interrupt handlers: one for MSI/MSI-X and another for IRQs. | ||
413 | They choose which handler to register with request_irq() based on the | ||
414 | return value from pci_enable_msi/msix(). | ||
415 | |||
416 | There are (at least) two really good reasons for using MSI: | ||
417 | 1) MSI is an exclusive interrupt vector by definition. | ||
418 | This means the interrupt handler doesn't have to verify | ||
419 | its device caused the interrupt. | ||
420 | |||
421 | 2) MSI avoids DMA/IRQ race conditions. DMA to host memory is guaranteed | ||
422 | to be visible to the host CPU(s) when the MSI is delivered. This | ||
423 | is important for both data coherency and avoiding stale control data. | ||
424 | This guarantee allows the driver to omit MMIO reads to flush | ||
425 | the DMA stream. | ||
426 | |||
427 | See drivers/infiniband/hw/mthca/ or drivers/net/tg3.c for examples | ||
428 | of MSI/MSI-X usage. | ||
429 | |||
430 | |||
431 | |||
432 | 4. PCI device shutdown | ||
433 | ~~~~~~~~~~~~~~~~~~~~~~~ | ||
434 | |||
435 | When a PCI device driver is being unloaded, most of the following | ||
436 | steps need to be performed: | ||
437 | |||
438 | Disable the device from generating IRQs | ||
439 | Release the IRQ (free_irq()) | ||
440 | Stop all DMA activity | ||
441 | Release DMA buffers (both streaming and consistent) | ||
442 | Unregister from other subsystems (e.g. scsi or netdev) | ||
443 | Disable device from responding to MMIO/IO Port addresses | ||
444 | Release MMIO/IO Port resource(s) | ||
445 | |||
446 | |||
447 | 4.1 Stop IRQs on the device | ||
448 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~ | ||
449 | How to do this is chip/device specific. If it's not done, it opens | ||
450 | the possibility of a "screaming interrupt" if (and only if) | ||
451 | the IRQ is shared with another device. | ||
452 | |||
453 | When the shared IRQ handler is "unhooked", the remaining devices | ||
454 | using the same IRQ line will still need the IRQ enabled. Thus if the | ||
455 | "unhooked" device asserts IRQ line, the system will respond assuming | ||
456 | it was one of the remaining devices asserted the IRQ line. Since none | ||
457 | of the other devices will handle the IRQ, the system will "hang" until | ||
458 | it decides the IRQ isn't going to get handled and masks the IRQ (100,000 | ||
459 | iterations later). Once the shared IRQ is masked, the remaining devices | ||
460 | will stop functioning properly. Not a nice situation. | ||
461 | |||
462 | This is another reason to use MSI or MSI-X if it's available. | ||
463 | MSI and MSI-X are defined to be exclusive interrupts and thus | ||
464 | are not susceptible to the "screaming interrupt" problem. | ||
465 | |||
466 | |||
467 | 4.2 Release the IRQ | ||
468 | ~~~~~~~~~~~~~~~~~~~ | ||
469 | Once the device is quiesced (no more IRQs), one can call free_irq(). | ||
470 | This function will return control once any pending IRQs are handled, | ||
471 | "unhook" the drivers IRQ handler from that IRQ, and finally release | ||
472 | the IRQ if no one else is using it. | ||
473 | |||
474 | |||
475 | 4.3 Stop all DMA activity | ||
476 | ~~~~~~~~~~~~~~~~~~~~~~~~~ | ||
477 | It's extremely important to stop all DMA operations BEFORE attempting | ||
478 | to deallocate DMA control data. Failure to do so can result in memory | ||
479 | corruption, hangs, and on some chip-sets a hard crash. | ||
187 | 480 | ||
188 | 4. How to access PCI config space | 481 | Stopping DMA after stopping the IRQs can avoid races where the |
482 | IRQ handler might restart DMA engines. | ||
483 | |||
484 | While this step sounds obvious and trivial, several "mature" drivers | ||
485 | didn't get this step right in the past. | ||
486 | |||
487 | |||
488 | 4.4 Release DMA buffers | ||
489 | ~~~~~~~~~~~~~~~~~~~~~~~ | ||
490 | Once DMA is stopped, clean up streaming DMA first. | ||
491 | I.e. unmap data buffers and return buffers to "upstream" | ||
492 | owners if there is one. | ||
493 | |||
494 | Then clean up "consistent" buffers which contain the control data. | ||
495 | |||
496 | See Documentation/DMA-API.txt for details on unmapping interfaces. | ||
497 | |||
498 | |||
499 | 4.5 Unregister from other subsystems | ||
500 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | ||
501 | Most low level PCI device drivers support some other subsystem | ||
502 | like USB, ALSA, SCSI, NetDev, Infiniband, etc. Make sure your | ||
503 | driver isn't losing resources from that other subsystem. | ||
504 | If this happens, typically the symptom is an Oops (panic) when | ||
505 | the subsystem attempts to call into a driver that has been unloaded. | ||
506 | |||
507 | |||
508 | 4.6 Disable Device from responding to MMIO/IO Port addresses | ||
509 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | ||
510 | io_unmap() MMIO or IO Port resources and then call pci_disable_device(). | ||
511 | This is the symmetric opposite of pci_enable_device(). | ||
512 | Do not access device registers after calling pci_disable_device(). | ||
513 | |||
514 | |||
515 | 4.7 Release MMIO/IO Port Resource(s) | ||
516 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | ||
517 | Call pci_release_region() to mark the MMIO or IO Port range as available. | ||
518 | Failure to do so usually results in the inability to reload the driver. | ||
519 | |||
520 | |||

206 | 541 | ||
207 | 542 | ||
208 | 5. Addresses and interrupts | ||
209 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~ | ||
210 | Memory and port addresses and interrupt numbers should NOT be read from the | ||
211 | config space. You should use the values in the pci_dev structure as they might | ||
212 | have been remapped by the kernel. | ||
213 | |||
214 | See Documentation/IO-mapping.txt for how to access device memory. | ||
215 | |||
216 | The device driver needs to call pci_request_region() to make sure | ||
217 | no other device is already using the same resource. The driver is expected | ||
218 | to determine MMIO and IO Port resource availability _before_ calling | ||
219 | pci_enable_device(). Conversely, drivers should call pci_release_region() | ||
220 | _after_ calling pci_disable_device(). The idea is to prevent two devices | ||
221 | colliding on the same address range. | ||
222 | |||
223 | Generic flavors of pci_request_region() are request_mem_region() | ||
224 | (for MMIO ranges) and request_region() (for IO Port ranges). | ||
225 | Use these for address resources that are not described by "normal" PCI | ||
226 | interfaces (e.g. BAR). | ||
227 | |||
228 | All interrupt handlers should be registered with IRQF_SHARED and use the devid | ||
229 | to map IRQs to devices (remember that all PCI interrupts are shared). | ||

611 | |||
612 | |||
613 | |||
614 | 10. pci_enable_device_bars() and Legacy I/O Port space | ||
615 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | ||
616 | |||
617 | Large servers may not be able to provide I/O port resources to all PCI | ||
618 | devices. I/O Port space is only 64KB on Intel Architecture[1] and is | ||
619 | likely also fragmented since the I/O base register of PCI-to-PCI | ||
620 | bridge will usually be aligned to a 4KB boundary[2]. On such systems, | ||
621 | pci_enable_device() and pci_request_region() will fail when | ||
622 | attempting to enable I/O Port regions that don't have I/O Port | ||
623 | resources assigned. | ||
624 | |||
625 | Fortunately, many PCI devices which request I/O Port resources also | ||
626 | provide access to the same registers via MMIO BARs. These devices can | ||
627 | be handled without using I/O port space and the drivers typically | ||
628 | offer a CONFIG_ option to only use MMIO regions | ||
629 | (e.g. CONFIG_TULIP_MMIO). PCI devices typically provide I/O port | ||
630 | interface for legacy OSes and will work when I/O port resources are not | ||
631 | assigned. The "PCI Local Bus Specification Revision 3.0" discusses | ||
632 | this on p.44, "IMPLEMENTATION NOTE". | ||
633 | |||
634 | If your PCI device driver doesn't need I/O port resources assigned to | ||
635 | I/O Port BARs, you should use pci_enable_device_bars() instead of | ||
636 | pci_enable_device() in order not to enable I/O port regions for the | ||
637 | corresponding devices. In addition, you should use | ||
638 | pci_request_selected_regions() and pci_release_selected_regions() | ||
639 | instead of pci_request_regions()/pci_release_regions() in order not to | ||
640 | request/release I/O port regions for the corresponding devices. | ||
641 | |||
642 | [1] Some systems support 64KB I/O port space per PCI segment. | ||
643 | [2] Some PCI-to-PCI bridges support optional 1KB aligned I/O base. | ||
644 | |||
645 | |||
646 | |||
647 | 11. MMIO Space and "Write Posting" | ||
648 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | ||
649 | |||
650 | Converting a driver from using I/O Port space to using MMIO space | ||
651 | often requires some additional changes. Specifically, "write posting" | ||
652 | needs to be handled. Many drivers (e.g. tg3, acenic, sym53c8xx_2) | ||
653 | already do this. I/O Port space guarantees write transactions reach the PCI | ||
654 | device before the CPU can continue. Writes to MMIO space allow the CPU | ||
655 | to continue before the transaction reaches the PCI device. HW weenies | ||
656 | call this "Write Posting" because the write completion is "posted" to | ||
657 | the CPU before the transaction has reached its destination. | ||
658 | |||
659 | Thus, timing sensitive code should add readl() where the CPU is | ||
660 | expected to wait before doing other work. The classic "bit banging" | ||
661 | sequence works fine for I/O Port space: | ||
662 | |||
663 | for (i = 8; --i; val >>= 1) { | ||
664 | outb(val & 1, ioport_reg); /* write bit */ | ||
665 | udelay(10); | ||
666 | } | ||
667 | |||
668 | The same sequence for MMIO space should be: | ||
669 | |||
670 | for (i = 8; --i; val >>= 1) { | ||
671 | writeb(val & 1, mmio_reg); /* write bit */ | ||
672 | readb(safe_mmio_reg); /* flush posted write */ | ||
673 | udelay(10); | ||
674 | } | ||
675 | |||
676 | It is important that "safe_mmio_reg" not have any side effects that | ||
677 | interferes with the correct operation of the device. | ||
678 | |||
679 | Another case to watch out for is when resetting a PCI device. Use PCI | ||
680 | Configuration space reads to flush the writel(). This will gracefully | ||
681 | handle the PCI master abort on all platforms if the PCI device is | ||
682 | expected to not respond to a readl(). Most x86 platforms will allow | ||
683 | MMIO reads to master abort (a.k.a. "Soft Fail") and return garbage | ||
684 | (e.g. ~0). But many RISC platforms will crash (a.k.a."Hard Fail"). | ||
