It is intended is to augment the +bus-specific drivers for bridges and devices by consolidating a set of data +and operations into globally accessible data structures. + +Current driver models implement some sort of tree-like structure (sometimes +just a list) for the devices they control. But, there is no linkage between +the different bus types. + +A common data structure can provide this linkage with little overhead: when a +bus driver discovers a particular device, it can insert it into the global +tree as well as its local tree. In fact, the local tree becomes just a subset +of the global tree. + +Common data fields can also be moved out of the local bus models into the +global model. Some of the manipulation of these fields can also be +consolidated. Most likely, manipulation functions will become a set +of helper functions, which the bus drivers wrap around to include any +bus-specific items. + +The common device and bridge interface currently reflects the goals of the +modern PC: namely the ability to do seamless Plug and Play, power management, +and hot plug. (The model dictated by Intel and Microsoft (read: ACPI) ensures +us that any device in the system may fit any of these criteria.) + +In reality, not every bus will be able to support such operations. But, most +buses will support a majority of those operations, and all future buses will. +In other words, a bus that doesn't support an operation is the exception, +instead of the other way around. + + +Drivers +~~~~~~~ + +The callbacks for bridges and devices are intended to be singular for a +particular type of bus. For each type of bus that has support compiled in the +kernel, there should be one statically allocated structure with the +appropriate callbacks that each device (or bridge) of that type share. + +Each bus layer should implement the callbacks for these drivers. It then +forwards the calls on to the device-specific callbacks. This means that +device-specific drivers must still implement callbacks for each operation. +But, they are not called from the top level driver layer. + +This does add another layer of indirection for calling one of these functions, +but there are benefits that are believed to outweigh this slowdown. + +First, it prevents device-specific drivers from having to know about the +global device layer. This speeds up integration time incredibly. It also +allows drivers to be more portable across kernel versions. Note that the +former was intentional, the latter is an added bonus. + +Second, this added indirection allows the bus to perform any additional logic +necessary for its child devices. A bus layer may add additional information to +the call, or translate it into something meaningful for its children. + +This could be done in the driver, but if it happens for every object of a +particular type, it is best done at a higher level. + +Recap +~~~~~ + +Instances of devices and bridges are allocated dynamically as the system +discovers their existence. Their fields describe the individual object. +Drivers - in the global sense - are statically allocated and singular for a +particular type of bus. They describe a set of operations that every type of +bus could implement, the implementation following the bus's semantics. + + +Downstream Access +~~~~~~~~~~~~~~~~~ + +Common data fields have been moved out of individual bus layers into a common +data structure. But, these fields must still be accessed by the bus layers, +and sometimes by the device-specific drivers. + +Other bus layers are encouraged to do what has been done for the PCI layer. +struct pci_dev now looks like this: + +struct pci_dev { + ... + + struct device device; +}; + +Note first that it is statically allocated. This means only one allocation on +device discovery. Note also that it is at the _end_ of struct pci_dev. This is +to make people think about what they're doing when switching between the bus +driver and the global driver; and to prevent against mindless casts between +the two. + +The PCI bus layer freely accesses the fields of struct device. It knows about +the structure of struct pci_dev, and it should know the structure of struct +device. PCI devices that have been converted generally do not touch the fields +of struct device. More precisely, device-specific drivers should not touch +fields of struct device unless there is a strong compelling reason to do so. + +This abstraction is prevention of unnecessary pain during transitional phases. +If the name of the field changes or is removed, then every downstream driver +will break. On the other hand, if only the bus layer (and not the device +layer) accesses struct device, it is only those that need to change. + + +User Interface +~~~~~~~~~~~~~~ + +By virtue of having a complete hierarchical view of all the devices in the +system, exporting a complete hierarchical view to userspace becomes relatively +easy. + +Whenever a device is inserted into the tree, a directory is created for it. +This directory may be populated at each layer of discovery - the global layer, +the bus layer, or the device layer. + +The global layer currently creates two files - 'status' and 'power'. The +former only reports the name of the device and its bus ID. The latter reports +the current power state of the device. It also be used to set the current +power state. + +The bus layer may also create files for the devices it finds while probing the +bus. For example, the PCI layer currently creates 'wake' and 'resource' files +for each PCI device. + +A device-specific driver may also export files in its directory to expose +device-specific data or tunable interfaces. + +These features were initially implemented using procfs. However, after one +conversation with Linus, a new filesystem - driverfs - was created to +implement these features. It is an in-memory filesystem, based heavily off of +ramfs, though it uses procfs as inspiration for its callback functionality. + +Each struct device has a 'struct driver_dir_entry' which encapsulates the +device's directory and the files within. + +Device Structures +~~~~~~~~~~~~~~~~~ + +struct device { + struct list_head bus_list; + struct iobus *parent; + struct iobus *subordinate; + + char name[DEVICE_NAME_SIZE]; + char bus_id[BUS_ID_SIZE]; + + struct driver_dir_entry * dir; + + spinlock_t lock; + atomic_t refcount; + + struct device_driver *driver; + void *driver_data; + void *platform_data; + + u32 current_state; + unsigned char *saved_state; +}; + +bus_list: + List of all devices on a particular bus; i.e. the device's siblings + +parent: + The parent bridge for the device. + +subordinate: + If the device is a bridge itself, this points to the struct io_bus that is + created for it. + +name: + Human readable (descriptive) name of device.

It is necessary to have a searchable bus id for each device; making it + ASCII allows us to use it for its directory name without translating it. + +dir: + Driver's driverfs directory. + +lock: + Driver specific lock. + +refcount: + Driver's usage count. + When this goes to 0, the device is assumed to be removed. It will be removed + from its parent's list of children. It's remove() callback will be called to + inform the driver to clean up after itself. + +driver: + Pointer to a struct device_driver, the common operations for each device. See + next section. + +driver_data: + Private data for the driver. + Much like the PCI implementation of this field, this allows device-specific + drivers to keep a pointer to a device-specific data. + +platform_data: + Data that the platform (firmware) provides about the device. + For example, the ACPI BIOS or EFI may have additional information about the + device that is not directly mappable to any existing kernel data structure. + It also allows the platform driver (e.g. ACPI) to a driver without the driver + having to have explicit knowledge of (atrocities like) ACPI. + + +current_state: + Current power state of the device. For PCI and other modern devices, this is + 0-3, though it's not necessarily limited to those values. + +saved_state: + Pointer to driver-specific set of saved state. + Having it here allows modules to be unloaded on system suspend and reloaded + on resume and maintain state across transitions. + It also allows generic drivers to maintain state across system state + transitions. + (I've implemented a generic PCI driver for devices that don't have a + device-specific driver. Instead of managing some vector of saved state + for each device the generic driver supports, it can simply store it here.) + + + +struct device_driver { + int (*probe) (struct device *dev); + int (*remove) (struct device *dev); + + int (*suspend) (struct device *dev, u32 state, u32 level); + int (*resume) (struct device *dev, u32 level); +} + +probe: + Check for device existence and associate driver with it. + +remove: + Dissociate driver with device.

Also, if it is a hotplug device (hotplug PCI, Cardbus), an + ejection event could take place here. + +suspend: + Perform one step of the device suspend process. + +resume: + Perform one step of the device resume process. + +The probe() and remove() callbacks are intended to be much simpler than the +current PCI correspondents. + +probe() should do the following only: + +- Check if hardware is present +- Register device interface +- Disable DMA/interrupts, etc, just in case. + +Some device initialisation was done in probe(). This should not be the case +anymore. All initialisation should take place in the open() call for the +device. + +Breaking initialisation code out must also be done for the resume() callback, +as most devices will have to be completely reinitialised when coming back from +a suspend state. + +remove() should simply unregister the device interface. + + +Device power management can be quite complicated, based exactly what is +desired to be done. Four operations sum up most of it: + +- OS directed power management. + The OS takes care of notifying all drivers that a suspend is requested, + saving device state, and powering devices down. +- Firmware controlled power management. + The OS only wants to notify devices that a suspend is requested. +- Device power management. + A user wants to place only one device in a low power state, and maybe save + state. +- System reboot. + The system wants to place devices in a quiescent state before the system is + reset. + +In an attempt to please all of these scenarios, the power management +transition for any device is broken up into several stages - notify, save +state, and power down. The disable stage, which should happen after notify and +before save state has been considered and may be implemented in the future. + +Depending on what the system-wide policy is (usually dictated by the power +management scheme present), each driver's suspend callback may be called +multiple times, each with a different stage. + +On all power management transitions, the stages should be called sequentially +(notify before save state; save state before power down). However, drivers +should not assume that any stage was called before hand. (If a driver gets a +power down call, it shouldn't assume notify or save state was called first.) +This allows the framework to be used seamlessly by all power management +actions. Hopefully. + +Resume transitions happen in a similar manner. They are broken up into two +stages currently (power on and restore state), though a third stage (enable) +may be added later. + +For suspend and resume transitions, the following values are defined to denote +the stage: + +enum{ + SUSPEND_NOTIFY, + SUSPEND_SAVE_STATE, + SUSPEND_POWER_DOWN, +}; + +enum { + RESUME_POWER_ON, + RESUME_RESTORE_STATE, +}; + + +During a system power transition, the device tree must be walked in order, +calling the suspend() or resume() callback for each node. This may happen +several times. + +Initially, this was done in kernel space. However, it has occurred to me that +doing recursion to a non-bounded depth is dangerous, and that there are a lot +of inherent race conditions in such an operation. + +Non-recursive walking of the device tree is possible. However, this makes for +convoluted code. + +No matter what, if the transition happens in kernel space, it is difficult to +gracefully recover from errors or to implement a policy that prevents one from +shutting down the device(s) you want to save state to. + +Instead, the walking of the device tree has been moved to userspace. When a +user requests the system to suspend, it will walk the device tree, as exported +via driverfs, and tell each device to go to sleep. It will do this multiple +times based on what the system policy is. + +Device resume should happen in the same manner when the system awakens. + +Each suspend stage is described below: + +SUSPEND_NOTIFY: + +This level to notify the driver that it is going to sleep. If it knows that it +cannot resume the hardware from the requested level, or it feels that it is +too important to be put to sleep, it should return an error from this function. + +It does not have to stop I/O requests or actually save state at this point. + +SUSPEND_DISABLE: + +The driver should stop taking I/O requests at this stage. Because the save +state stage happens afterwards, the driver may not want to physically disable +the device; only mark itself unavailable if possible. + +SUSPEND_SAVE_STATE: + +The driver should allocate memory and save any device state that is relevant +for the state it is going to enter. + +SUSPEND_POWER_DOWN: + +The driver should place the device in the power state requested. + + +For resume, the stages are defined as follows: + +RESUME_POWER_ON: + +Devices should be powered on and reinitialised to some known working state. + +RESUME_RESTORE_STATE: + +The driver should restore device state to its pre-suspend state and free any +memory allocated for its saved state. + +RESUME_ENABLE: + +The device should start taking I/O requests again. + + +Each driver does not have to implement each stage. But, it if it does +implemente a stage, it should do what is described above.

For example, PCI and USB both export +device information via procfs or usbdevfs. + +In these cases, the files or directories are in nearly random places +in /proc. One benefit of driverfs is that it can consolidate all of +these interfaces to one standard location. + + +Why it's better than procfs: +~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +This of course can't happen without changing every single driver that +exports a procfs interface, and having some coordination between all +of them as to what the proper place for their files is. Or can it? + + +driverfs was developed in conjunction with the new driver model for +the 2.5 kernel. In that model, the system has one unified tree of all +the devices that are present in the system. It follows naturally that +this tree can be exported to userspace in the same order. + +So, every bus and every device gets a directory in the filesystem. +This directory is created when the device is registered in the tree; +before the driver actually gets a initialised. The dentry for this +directory is stored in the struct device for this driver, so the +driver has access to it. + +Now, every driver has one standard place to export its files. + +Granted, the location of the file is not as intuitive as it may have +been under procfs. But, I argue that with the exception of +/proc/bus/pci, none of the files had intuitive locations. I also argue +that the development of userspace tools can help cope with these +changes and inconsistencies in locations. + + +Why we're not just using procfs: +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +When developing the new driver model, it was initially implemented +with a procfs tree. In explaining the concept to Linus, he said "Don't +use proc." + +I was a little shocked (especially considering I had already +implemented it using procfs). "What do you mean 'don't use proc'?" + +His argument was that too many things use proc that shouldn't. And +even more things misuse proc that shouldn't. On top of that, procfs +was written before the VFS layer was written, so it doesn't use the +dcache. It reimplements many of the same features that the dcache +does, and is in general, crufty. + +So, he told me to write my own. Soon after, he pointed me at ramfs, +the simplest filesystem known to man. + +Consequently, we have a virtual fileystem based heavily on ramfs, and +borrowing some conceptual functionality from procfs. + +It may suck, but it does what it was designed to. At least so far. + + +How it works: +~~~~~~~~~~~~~ + +Directories are encapsulated like this: + +struct driver_dir_entry { + char * name; + struct dentry * dentry; + mode_t mode; + struct list_head files; +}; + +name: + Name of the directory. +dentry: + Dentry for the directory. +mode: + Permissions of the directory. +files: + Linked list of driver_file_entry's that are in the directory. + + +To create a directory, one first calls + +struct driver_dir_entry * +driverfs_create_dir_entry(const char * name, mode_t mode); + +which allocates and initialises a struct driver_dir_entry. Then to actually +create the directory: + +int driverfs_create_dir(struct driver_dir_entry *, struct driver_dir_entry *); + +To remove a directory: + +void driverfs_remove_dir(struct driver_dir_entry * entry); + + +Files are encapsulated like this: + +struct driver_file_entry { + struct driver_dir_entry * parent; + struct list_head node; + char * name; + mode_t mode; + struct dentry * dentry; + void * data; + struct driverfs_operations * ops; +}; + +struct driverfs_operations { + ssize_t (*read) (char *, size_t, loff_t, void *); + ssize_t (*write)(const char *, size_t, loff_t, void*); +}; + +node: + Node in its parent directory's list of files. + +name: + The name of the file. + +dentry: + The dentry for the file. + +data: + Caller specific data that is passed to the callbacks when they + are called. + +ops: + Operations for the file. Currently, this only contains read() and write() + callbacks for the file. + +To create a file, one first calls + +struct driver_file_entry * +driverfs_create_entry (const char * name, mode_t mode, + struct driverfs_operations * ops, void * data); + +That allocates and initialises a struct driver_file_entry. Then, to actually +create a file, one calls + +int driverfs_create_file(struct driver_file_entry * entry, + struct driver_dir_entry * parent); + + +To remove a file, one calls + +void driverfs_remove_file(struct driver_dir_entry *, const char * name); + + +The callback functionality is similar to the way procfs works. When a +user performs a read(2) or write(2) on the file, it first calls a +driverfs function. This function then checks for a non-NULL pointer in +the file->private_data field, which it assumes to be a pointer to a +struct driver_file_entry. + +It then checks for the appropriate callback and calls it. + + +What driverfs is not: +~~~~~~~~~~~~~~~~~~~~~ +It is not a replacement for either devfs or procfs. + +It does not handle device nodes, like devfs is intended to do. I think +this functionality is possible, but indeed think that integration of +the device nodes and control files should be done. Whether driverfs or +devfs, or something else, is the place to do it, I don't know. + +It is not intended to be a replacement for all of the procfs +functionality. I think that many of the driver files should be moved +out of /proc (and maybe a few other things as well ;). + + + +Limitations: +~~~~~~~~~~~~ +The driverfs functions assume that at most a page is being either read +or written each time. + + +Possible bugs: +~~~~~~~~~~~~~~ +It may not deal with offsets and/or seeks very well, especially if +they cross a page boundary. + +There may be locking issues when dynamically adding/removing files and +directories rapidly (like if you have a hot plug device). + +There are some people that believe that filesystems which add +files/directories dynamically based on the presence of devices are +inherently flawed.

This version of the driver allocates skbuffs -for the Rx ring buffers at open() time and passes the skb->data field to the -Tulip as receive data buffers.

When the incoming frame is larger, the skbuff is -passed directly up the protocol stack and replaced by a newly allocated -skbuff. - -The RX_COPYBREAK value is chosen to trade-off the memory wasted by -using a full-sized skbuff for small frames vs. the copying costs of larger -frames. For small frames the copying cost is negligible (esp. considering -that we are pre-loading the cache with immediately useful header -information). For large frames the copying cost is non-trivial, and the -larger copy might flush the cache of useful data. A subtle aspect of this -choice is that the Tulip only receives into longword aligned buffers, thus -the IP header at offset 14 isn't longword aligned for further processing. -Copied frames are put into the new skbuff at an offset of "+2", thus copying -has the beneficial effect of aligning the IP header and preloading the -cache. - -Synchronization ---------------- -The driver runs as two independent, single-threaded flows of control. One -is the send-packet routine, which enforces single-threaded use by the -dev->tbusy flag. The other thread is the interrupt handler, which is single -threaded by the hardware and other software. - -The send packet thread has partial control over the Tx ring and 'dev->tbusy' -flag. It sets the tbusy flag whenever it's queuing a Tx packet. If the next -queue slot is empty, it clears the tbusy flag when finished otherwise it sets -the 'tp->tx_full' flag. - -The interrupt handler has exclusive control over the Rx ring and records stats -from the Tx ring. (The Tx-done interrupt can't be selectively turned off, so -we can't avoid the interrupt overhead by having the Tx routine reap the Tx -stats.) After reaping the stats, it marks the queue entry as empty by setting -the 'base' to zero. Iff the 'tp->tx_full' flag is set, it clears both the -tx_full and tbusy flags. - -Notes -===== - -Thanks to Duke Kamstra of SMC for long ago providing an EtherPower board. -Greg LaPolla at Linksys provided PNIC and other Linksys boards. -Znyx provided a four-port card for testing. - -References -========== - -http://cesdis.gsfc.nasa.gov/linux/misc/NWay.html -http://www.digital.com (search for current 21*4* datasheets and "21X4 SROM") -http://www.national.com/pf/DP/DP83840A.html -http://www.asix.com.tw/pmac.htm -http://www.admtek.com.tw/ - -Errata -====== - -The old DEC databooks were light on details. -The 21040 databook claims that CSR13, CSR14, and CSR15 should each be the last -register of the set CSR12-15 written.
