In - effect, it's identical to PATA hardware reset. Note that - this can be done with the standard SCR Control register. - As such, it's usually easier to implement than software - reset. - - - - - - - - One more thing to consider when resetting devices is that - resetting clears certain configuration parameters and they - need to be set to their previous or newly adjusted values - after reset. - - - - Parameters affected are. - - - - - - - CHS set up with INITIALIZE DEVICE PARAMETERS (seldomly used) - - - - - - Parameters set with SET FEATURES including transfer mode setting - - - - - - Block count set with SET MULTIPLE MODE - - - - - - Other parameters (SET MAX, MEDIA LOCK...) - - - - - - - ATA/ATAPI standard specifies that some parameters must be - maintained across hardware or software reset, but doesn't - strictly specify all of them. Always reconfiguring needed - parameters after reset is required for robustness. Note that - this also applies when resuming from deep sleep (power-off). - - - - Also, ATA/ATAPI standard requires that IDENTIFY DEVICE / - IDENTIFY PACKET DEVICE is issued after any configuration - parameter is updated or a hardware reset and the result used - for further operation. OS driver is required to implement - revalidation mechanism to support this. - - - - - - Reconfigure transport - - - For both PATA and SATA, a lot of corners are cut for cheap - connectors, cables or controllers and it's quite common to see - high transmission error rate.

All of this is mandated by Intel's -specification for ia64 SAL, error recovery and and unwind, it is not as -if we have a choice here. - -* MCA occurs on one cpu, usually due to a double bit memory error. - This is the monarch cpu. - -* SAL sends an MCA rendezvous interrupt (which is a normal interrupt) - to all the other cpus, the slaves. - -* Slave cpus that receive the MCA interrupt call down into SAL, they - end up spinning disabled while the MCA is being serviced. - -* If any slave cpu was already spinning disabled when the MCA occurred - then it cannot service the MCA interrupt. SAL waits ~20 seconds then - sends an unmaskable INIT event to the slave cpus that have not - already rendezvoused. - -* Because MCA/INIT can be delivered at any time, including when the cpu - is down in PAL in physical mode, the registers at the time of the - event are _completely_ undefined. In particular the MCA/INIT - handlers cannot rely on the thread pointer, PAL physical mode can - (and does) modify TP. It is allowed to do that as long as it resets - TP on return. However MCA/INIT events expose us to these PAL - internal TP changes. Hence curr_task(). - -* If an MCA/INIT event occurs while the kernel was running (not user - space) and the kernel has called PAL then the MCA/INIT handler cannot - assume that the kernel stack is in a fit state to be used. Mainly - because PAL may or may not maintain the stack pointer internally. - Because the MCA/INIT handlers cannot trust the kernel stack, they - have to use their own, per-cpu stacks. The MCA/INIT stacks are - preformatted with just enough task state to let the relevant handlers - do their job. - -* Unlike most other architectures, the ia64 struct task is embedded in - the kernel stack[1]. So switching to a new kernel stack means that - we switch to a new task as well. Because various bits of the kernel - assume that current points into the struct task, switching to a new - stack also means a new value for current. - -* Once all slaves have rendezvoused and are spinning disabled, the - monarch is entered. The monarch now tries to diagnose the problem - and decide if it can recover or not. - -* Part of the monarch's job is to look at the state of all the other - tasks. The only way to do that on ia64 is to call the unwinder, - as mandated by Intel. - -* The starting point for the unwind depends on whether a task is - running or not. That is, whether it is on a cpu or is blocked. The - monarch has to determine whether or not a task is on a cpu before it - knows how to start unwinding it. The tasks that received an MCA or - INIT event are no longer running, they have been converted to blocked - tasks. But (and its a big but), the cpus that received the MCA - rendezvous interrupt are still running on their normal kernel stacks! - -* To distinguish between these two cases, the monarch must know which - tasks are on a cpu and which are not. Hence each slave cpu that - switches to an MCA/INIT stack, registers its new stack using - set_curr_task(), so the monarch can tell that the _original_ task is - no longer running on that cpu. That gives us a decent chance of - getting a valid backtrace of the _original_ task. - -* MCA/INIT can be nested, to a depth of 2 on any cpu. In the case of a - nested error, we want diagnostics on the MCA/INIT handler that - failed, not on the task that was originally running. Again this - requires set_curr_task() so the MCA/INIT handlers can register their - own stack as running on that cpu. Then a recursive error gets a - trace of the failing handler's "task". - -[1] My (Keith Owens) original design called for ia64 to separate its - struct task and the kernel stacks. Then the MCA/INIT data would be - chained stacks like i386 interrupt stacks. But that required - radical surgery on the rest of ia64, plus extra hard wired TLB - entries with its associated performance degradation. David - Mosberger vetoed that approach. Which meant that separate kernel - stacks meant separate "tasks" for the MCA/INIT handlers. - ---- - -INIT is less complicated than MCA. Pressing the nmi button or using -the equivalent command on the management console sends INIT to all -cpus. SAL picks one one of the cpus as the monarch and the rest are -slaves. All the OS INIT handlers are entered at approximately the same -time. The OS monarch prints the state of all tasks and returns, after -which the slaves return and the system resumes. - -At least that is what is supposed to happen. Alas there are broken -versions of SAL out there. Some drive all the cpus as monarchs. Some -drive them all as slaves. Some drive one cpu as monarch, wait for that -cpu to return from the OS then drive the rest as slaves. Some versions -of SAL cannot even cope with returning from the OS, they spin inside -SAL on resume. The OS INIT code has workarounds for some of these -broken SAL symptoms, but some simply cannot be fixed from the OS side. - ---- - -The scheduler hooks used by ia64 (curr_task, set_curr_task) are layer -violations. Unfortunately MCA/INIT start off as massive layer -violations (can occur at _any_ time) and they build from there. - -At least ia64 makes an attempt at recovering from hardware errors, but -it is a difficult problem because of the asynchronous nature of these -errors. When processing an unmaskable interrupt we sometimes need -special code to cope with our inability to take any locks. - ---- - -How is ia64 MCA/INIT different from x86 NMI? - -* x86 NMI typically gets delivered to one cpu. MCA/INIT gets sent to - all cpus. - -* x86 NMI cannot be nested. MCA/INIT can be nested, to a depth of 2 - per cpu. - -* x86 has a separate struct task which points to one of multiple kernel - stacks. ia64 has the struct task embedded in the single kernel - stack, so switching stack means switching task. - -* x86 does not call the BIOS so the NMI handler does not have to worry - about any registers having changed. MCA/INIT can occur while the cpu - is in PAL in physical mode, with undefined registers and an undefined - kernel stack. - -* i386 backtrace is not very sensitive to whether a process is running - or not. ia64 unwind is very, very sensitive to whether a process is - running or not. - ---- - -What happens when MCA/INIT is delivered what a cpu is running user -space code? - -The user mode registers are stored in the RSE area of the MCA/INIT on -entry to the OS and are restored from there on return to SAL, so user -mode registers are preserved across a recoverable MCA/INIT. Since the -OS has no idea what unwind data is available for the user space stack, -MCA/INIT never tries to backtrace user space. Which means that the OS -does not bother making the user space process look like a blocked task, -i.e. the OS does not copy pt_regs and switch_stack to the user space -stack. Also the OS has no idea how big the user space RSE and memory -stacks are, which makes it too risky to copy the saved state to a user -mode stack. - ---- - -How do we get a backtrace on the tasks that were running when MCA/INIT -was delivered? - -mca.c:::ia64_mca_modify_original_stack(). That identifies and -verifies the original kernel stack, copies the dirty registers from -the MCA/INIT stack's RSE to the original stack's RSE, copies the -skeleton struct pt_regs and switch_stack to the original stack, fills -in the skeleton structures from the PAL minstate area and updates the -original stack's thread.ksp. That makes the original stack look -exactly like any other blocked task, i.e. it now appears to be -sleeping. To get a backtrace, just start with thread.ksp for the -original task and unwind like any other sleeping task. - ---- - -How do we identify the tasks that were running when MCA/INIT was -delivered? - -If the previous task has been verified and converted to a blocked -state, then sos->prev_task on the MCA/INIT stack is updated to point to -the previous task. You can look at that field in dumps or debuggers. -To help distinguish between the handler and the original tasks, -handlers have _TIF_MCA_INIT set in thread_info.flags. - -The sos data is always in the MCA/INIT handler stack, at offset -MCA_SOS_OFFSET. You can get that value from mca_asm.h or calculate it -as KERNEL_STACK_SIZE - sizeof(struct pt_regs) - sizeof(struct -ia64_sal_os_state), with 16 byte alignment for all structures. - -Also the comm field of the MCA/INIT task is modified to include the pid -of the original task, for humans to use.

The kernel interface returns a pointer directly to the -key, and it's up to the caller to destroy the key. - -The userspace interface links the key to a keyring associated with the process -to prevent the key from going away, and returns the serial number of the key to -the caller. - - -=========== -THE PROCESS -=========== - -A request proceeds in the following manner: - - (1) Process A calls request_key() [the userspace syscall calls the kernel - interface]. - - (2) request_key() searches the process's subscribed keyrings to see if there's - a suitable key there. If there is, it returns the key. If there isn't, and - callout_info is not set, an error is returned. Otherwise the process - proceeds to the next step. - - (3) request_key() sees that A doesn't have the desired key yet, so it creates - two things: - - (a) An uninstantiated key U of requested type and description. - - (b) An authorisation key V that refers to key U and notes that process A - is the context in which key U should be instantiated and secured, and - from which associated key requests may be satisfied. - - (4) request_key() then forks and executes /sbin/request-key with a new session - keyring that contains a link to auth key V. - - (5) /sbin/request-key execs an appropriate program to perform the actual - instantiation. - - (6) The program may want to access another key from A's context (say a - Kerberos TGT key). It just requests the appropriate key, and the keyring - search notes that the session keyring has auth key V in its bottom level. - - This will permit it to then search the keyrings of process A with the - UID, GID, groups and security info of process A as if it was process A, - and come up with key W. - - (7) The program then does what it must to get the data with which to - instantiate key U, using key W as a reference (perhaps it contacts a - Kerberos server using the TGT) and then instantiates key U. - - (8) Upon instantiating key U, auth key V is automatically revoked so that it - may not be used again. - - (9) The program then exits 0 and request_key() deletes key V and returns key - U to the caller. - -This also extends further.

Distance pointers never point before the beginning of the output + stream. + 2. Distance pointers can point back across blocks, up to 32k away. + 3.

(Zero + would be more efficient, but perhaps a little confusing.) If two + codes exist, they are coded using one bit each (0 and 1). + 5. There is no way of sending zero distance codes--a dummy must be + sent if there are none. (History: a pre 2.0 version of PKZIP would + store blocks with no distance codes, but this was discovered to be + too harsh a criterion.) Valid only for 1.93a. 2.04c does allow + zero distance codes, which is sent as one code of zero bits in + length. + 6. There are up to 286 literal/length codes. Code 256 represents the + end-of-block. Note however that the static length tree defines + 288 codes just to fill out the Huffman codes. Codes 286 and 287 + cannot be used though, since there is no length base or extra bits + defined for them. Similarily, there are up to 30 distance codes. + However, static trees define 32 codes (all 5 bits) to fill out the + Huffman codes, but the last two had better not show up in the data. + 7. Unzip can check dynamic Huffman blocks for complete code sets. + The exception is that a single code would not be complete (see #4). + 8. The five bits following the block type is really the number of + literal codes sent minus 257. + 9. Length codes 8,16,16 are interpreted as 13 length codes of 8 bits + (1+6+6). Therefore, to output three times the length, you output + three codes (1+1+1), whereas to output four times the same length, + you only need two codes (1+3). Hmm. + 10. In the tree reconstruction algorithm, Code = Code + Increment + only if BitLength(i) is not zero. (Pretty obvious.) + 11. Correction: 4 Bits: # of Bit Length codes - 4 (4 - 19) + 12. Note: length code 284 can represent 227-258, but length code 285 + really is 258. The last length deserves its own, short code + since it gets used a lot in very redundant files. The length + 258 is special since 258 - 3 (the min match length) is 255. + 13. The literal/length and distance code bit lengths are read as a + single stream of lengths.

The most common codes are necessarily the + shortest codes, so those codes dominate the decoding time, and hence + the speed. The idea is you can have a shorter table that decodes the + shorter, more probable codes, and then point to subsidiary tables for + the longer codes. The time it costs to decode the longer codes is + then traded against the time it takes to make longer tables. + + This results of this trade are in the variables lbits and dbits + below. lbits is the number of bits the first level table for literal/ + length codes can decode in one step, and dbits is the same thing for + the distance codes. Subsequent tables are also less than or equal to + those sizes. These values may be adjusted either when all of the + codes are shorter than that, in which case the longest code length in + bits is used, or when the shortest code is *longer* than the requested + table size, in which case the length of the shortest code in bits is + used. + + There are two different values for the two tables, since they code a + different number of possibilities each. The literal/length table + codes 286 possible values, or in a flat code, a little over eight + bits. The distance table codes 30 possible values, or a little less + than five bits, flat. The optimum values for speed end up being + about one bit more than those, so lbits is 8+1 and dbits is 5+1. + The optimum values may differ though from machine to machine, and + possibly even between compilers.

They can also be used for QoS. for that - * to work, however, QoS information needs to be exposed down to the driver - * level so that subqueues get targetted to particular transmit rings. - * alternatively, the queues can be configured via use of the all-purpose - * ioctl. - * - * RX DATA: the rx completion ring has all the info, but the rx desc - * ring has all of the data. RX can conceivably come in under multiple - * interrupts, but the INT# assignment needs to be set up properly by - * the BIOS and conveyed to the driver. PCI BIOSes don't know how to do - * that. also, the two descriptor rings are designed to distinguish between - * encrypted and non-encrypted packets, but we use them for buffering - * instead. - * - * by default, the selective clear mask is set up to process rx packets. - */ - -#include -#include - -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include - -#include -#include -#include -#include -#include -#include -#include -#include -#include - -#include - -#include -#include -#include -#include -#include - -#define cas_page_map(x) kmap_atomic((x), KM_SKB_DATA_SOFTIRQ) -#define cas_page_unmap(x) kunmap_atomic((x), KM_SKB_DATA_SOFTIRQ) -#define CAS_NCPUS num_online_cpus() - -#if defined(CONFIG_CASSINI_NAPI) && defined(HAVE_NETDEV_POLL) -#define USE_NAPI -#define cas_skb_release(x) netif_receive_skb(x) -#else -#define cas_skb_release(x) netif_rx(x) -#endif - -/* select which firmware to use */ -#define USE_HP_WORKAROUND -#define HP_WORKAROUND_DEFAULT /* select which firmware to use as default */ -#define CAS_HP_ALT_FIRMWARE cas_prog_null /* alternate firmware */ - -#include "cassini.h" - -#define USE_TX_COMPWB /* use completion writeback registers */ -#define USE_CSMA_CD_PROTO /* standard CSMA/CD */ -#define USE_RX_BLANK /* hw interrupt mitigation */ -#undef USE_ENTROPY_DEV /* don't test for entropy device */ - -/* NOTE: these aren't useable unless PCI interrupts can be assigned. - * also, we need to make cp->lock finer-grained. - */ -#undef USE_PCI_INTB -#undef USE_PCI_INTC -#undef USE_PCI_INTD -#undef USE_QOS - -#undef USE_VPD_DEBUG /* debug vpd information if defined */ - -/* rx processing options */ -#define USE_PAGE_ORDER /* specify to allocate large rx pages */ -#define RX_DONT_BATCH 0 /* if 1, don't batch flows */ -#define RX_COPY_ALWAYS 0 /* if 0, use frags */ -#define RX_COPY_MIN 64 /* copy a little to make upper layers happy */ -#undef RX_COUNT_BUFFERS /* define to calculate RX buffer stats */ - -#define DRV_MODULE_NAME "cassini" -#define PFX DRV_MODULE_NAME ": " -#define DRV_MODULE_VERSION "1.4" -#define DRV_MODULE_RELDATE "1 July 2004" - -#define CAS_DEF_MSG_ENABLE \ - (NETIF_MSG_DRV | \ - NETIF_MSG_PROBE | \ - NETIF_MSG_LINK | \ - NETIF_MSG_TIMER | \ - NETIF_MSG_IFDOWN | \ - NETIF_MSG_IFUP | \ - NETIF_MSG_RX_ERR | \ - NETIF_MSG_TX_ERR) - -/* length of time before we decide the hardware is borked, - * and dev->tx_timeout() should be called to fix the problem - */ -#define CAS_TX_TIMEOUT (HZ) -#define CAS_LINK_TIMEOUT (22*HZ/10) -#define CAS_LINK_FAST_TIMEOUT (1) - -/* timeout values for state changing. these specify the number - * of 10us delays to be used before giving up. - */ -#define STOP_TRIES_PHY 1000 -#define STOP_TRIES 5000 - -/* specify a minimum frame size to deal with some fifo issues - * max mtu == 2 * page size - ethernet header - 64 - swivel = - * 2 * page_size - 0x50 - */ -#define CAS_MIN_FRAME 97 -#define CAS_1000MB_MIN_FRAME 255 -#define CAS_MIN_MTU 60 -#define CAS_MAX_MTU min(((cp->page_size << 1) - 0x50), 9000) - -#if 1 -/* - * Eliminate these and use separate atomic counters for each, to - * avoid a race condition. - */ -#else -#define CAS_RESET_MTU 1 -#define CAS_RESET_ALL 2 -#define CAS_RESET_SPARE 3 -#endif - -static char version[] __devinitdata = - DRV_MODULE_NAME ".c:v" DRV_MODULE_VERSION " (" DRV_MODULE_RELDATE ")\n"; - -MODULE_AUTHOR("Adrian Sun (asun@darksunrising.com)"); -MODULE_DESCRIPTION("Sun Cassini(+) ethernet driver"); -MODULE_LICENSE("GPL"); -MODULE_PARM(cassini_debug, "i"); -MODULE_PARM_DESC(cassini_debug, "Cassini bitmapped debugging message enable value"); -MODULE_PARM(link_mode, "i"); -MODULE_PARM_DESC(link_mode, "default link mode"); - -/* - * Work around for a PCS bug in which the link goes down due to the chip - * being confused and never showing a link status of "up." - */ -#define DEFAULT_LINKDOWN_TIMEOUT 5 -/* - * Value in seconds, for user input. - */ -static int linkdown_timeout = DEFAULT_LINKDOWN_TIMEOUT; -MODULE_PARM(linkdown_timeout, "i"); -MODULE_PARM_DESC(linkdown_timeout, -"min reset interval in sec. for PCS linkdown issue; disabled if not positive"); - -/* - * value in 'ticks' (units used by jiffies).

This makes - things easier for some drivers. - - (04/10/2002) gkh - added serial_read_proc function which creates a - /proc/tty/driver/usb-serial file. - - (03/27/2002) gkh - Got USB serial console code working properly and merged into the main - version of the tree. Thanks to Randy Dunlap for the initial version - of this code, and for pushing me to finish it up. - The USB serial console works with any usb serial driver device. - - (03/21/2002) gkh - Moved all manipulation of port->open_count into the core. Now the - individual driver's open and close functions are called only when the - first open() and last close() is called. Making the drivers a bit - smaller and simpler. - Fixed a bug if a driver didn't have the owner field set. - - (02/26/2002) gkh - Moved all locking into the main serial_* functions, instead of having - the individual drivers have to grab the port semaphore. This should - reduce races. - Reworked the MOD_INC logic a bit to always increment and decrement, even - if the generic driver is being used. - - (10/10/2001) gkh - usb_serial_disconnect() now sets the serial->dev pointer is to NULL to - help prevent child drivers from accessing the device since it is now - gone. - - (09/13/2001) gkh - Moved generic driver initialize after we have registered with the USB - core. Thanks to Randy Dunlap for pointing this problem out. - - (07/03/2001) gkh - Fixed module paramater size.

This allows people who only want the Visor - support to not pay the memory size price of the WhiteHEAT. - Fixed bug where the generic driver (idVendor=0000 and idProduct=0000) - grabbed the root hub. Not good. - - version 0.4.0 (01/10/2000) gkh - Added whiteheat.h containing the firmware for the ConnectTech WhiteHEAT - device.

We're legal now! - - version 0.2.1 (12/14/99) gkh - Fixed bug that happens when device node is opened when there isn't a - device attached to it. Thanks to marek@webdesign.no for noticing this. - - version 0.2.0 (11/10/99) gkh - Split up internals to make it easier to add different types of serial - converters to the code. - Added a "generic" driver that gets it's vendor and product id - from when the module is loaded. Thanks to David E. Nelson (dnelson@jump.net) - for the idea and sample code (from the usb scanner driver.) - Cleared up any licensing questions by releasing it under the GNU GPL. - - version 0.1.2 (10/25/99) gkh - Fixed bug in detecting device. - - version 0.1.1 (10/05/99) gkh - Changed the major number to not conflict with anything else. - - version 0.1 (09/28/99) gkh - Can recognize the two different devices and start up a read from - device when asked to. Writes also work. No control signals yet, this - all is vendor specific data (i.e. no spec), also no control for - different baud rates or other bit settings. - Currently we are using the same devid as the acm driver. This needs - to change. - ------------------------------------------------------------------------ -visor.c Change Log comments: - - (06/03/2003) Judd Montgomery - Added support for module parameter options for untested/unknown - devices. - - (03/09/2003) gkh - Added support for the Sony Clie NZ90V device.
