The difference is as follows: - * - * With AIC7XXX_FAKE_NEGOTIATION_CMDS not set (commented out) - * When the driver is in need of issuing a negotiation command for any - * given device, it will add the negotiation message on to part of a - * regular SCSI command for the device. In the process, if the device - * is configured for and using tagged queueing, then the code will - * also issue that single command as a non-tagged command, attach the - * negotiation message to that one command, and use a temporary - * queue depth of one to keep the untagged and tagged commands from - * overlapping. - * Pros: This doesn't use any extra SCB structures, it's simple, it - * works most of the time (if not all of the time now), and - * since we get the device capability info frmo the INQUIRY data - * now, shouldn't cause any problems. - * Cons: When we need to send a negotiation command to a device, we - * must use a command that is being sent to LUN 0 of the device. - * If we try sending one to high LUN numbers, then some devices - * get noticeably upset. Since we have to wait for a command with - * LUN == 0 to come along, we may not be able to renegotiate when - * we want if the user is actually using say LUN 1 of a CD Changer - * instead of using LUN 0 for an extended period of time. - * - * With AIC7XXX_FAKE_NEGOTIATION_CMDS defined - * When we need to negotiate with a device, instead of attaching our - * negotiation message to an existing command, we insert our own - * fictional Scsi_Cmnd into the chain that has the negotiation message - * attached to it. We send this one command as untagged regardless - * of the device type, and we fiddle with the queue depth the same as - * we would with the option unset to avoid overlapping commands. The - * primary difference between this and the unset option is that the - * negotiation message is no longer attached to a specific command, - * instead it is its own command and is merely triggered by a - * combination of both A) We need to negotiate and B) The mid level - * SCSI code has sent us a command. We still don't do any negotiation - * unless there is a valid SCSI command to be processed. - * Pros: This fixes the problem above in the Cons section. Since we - * issue our own fake command, we can set the LUN to 0 regardless - * of what the LUN is in the real command. It also means that if - * the device get's nasty over negotiation issues, it won't be - * showing up on a regular command, so we won't get any SENSE buffer - * data or STATUS_BYTE returns to the mid level code that are caused - * by snits in the negotiation code. - * Cons: We add more code, and more complexity. This means more ways - * in which things could break. It means a larger driver. It means - * more resource consumption for the fake commands. However, the - * biggest problem is this. Take a system where there is a CD-ROM - * on the SCSI bus. Someone has a CD in the CD-ROM and is using it. - * For some reason the SCSI bus gets reset. We don't touch the - * CD-ROM again for quite a period of time (so we don't renegotiate - * after the reset until we do touch the CD-ROM again). In the - * time while we aren't using the CD-ROM, the current disc is - * removed and a new one put in. When we go to check that disc, we - * will first have to renegotiate. In so doing, we issue our fake - * SCSI command, which happens to be TEST_UNIT_READY. The CD-ROM - * negotiates with us, then responds to our fake command with a - * CHECK_CONDITION status. We REQUEST_SENSE from the CD-ROM, it - * then sends the SENSE data to our fake command to tell it that - * it has been through a disc change. There, now we've cleared out - * the SENSE data along with our negotiation command, and when the - * real command executes, it won't pick up that the CD was changed. - * That's the biggest Con to this approach. In the future, I could - * probably code around this problem though, so this option is still - * viable. - * - * So, which command style should you use? I would appreciate it if people - * could try out both types. I want to know about any cases where one - * method works and the other doesn't. If one method works on significantly - * more systems than another, then it will become the default. If the second - * option turns out to work best, then I'll find a way to work around that - * big con I listed. - * - * -- July 7, 02:33 - * OK...I just added some code that should make the Con listed for the - * fake commands a non issue now.

All is not lost if application writers - then back off the amount they are requesting. The value returned by - the SG_GET_RESERVED_SIZE ioctl is guaranteed to be available (one - per fd). This driver does the following: - - attempts to reserve a SG_SCATTER_SZ sized buffer on open(). The - actual amount reserved is given by the SG_GET_RESERVED_SIZE ioctl(). - - each write() needs to reserve a DMA buffer of the size of the - data buffer indicated (excluding sg_header and command overhead). - This buffer, depending on its size, adapter type (ISA or not) and - the amount of memory available will be obtained from the kernel - directly (get_free_pages or kmalloc) or the from the scsi mid-level - dma pool (taking care not to exhaust it). - If the buffer requested is > SG_SCATTER_SZ or memory is tight then - scatter-gather will be used if supported by the adapter. - - write() will also attempt to use the buffer reserved on open() - if it is large enough. - The above strategy ensures that a write() can always depend on a buffer - of the size indicated by the SG_GET_RESERVED_SIZE ioctl() (which could be - 0, but at least the app knows things are tight in advance). - Hence application writers can adopt quite aggressive strategies (e.g. - requesting 512KB) and scale them back in the face of ENOMEM errors. - N.B. Queuing up commands also ties up kernel memory. + This device currently uses "indirect IO" in the sense that data is + DMAed into kernel buffers from the hardware and afterwards is + transferred into the user space (or vice versa if you are writing). + Transfer speeds or up to 20 to 30MBytes/sec have been measured using + indirect IO. For faster throughputs "direct IO" which cuts out the + double handling of data is required. This will also need a new interface. + + Grabbing memory for those kernel buffers used in this driver for DMA may + cause the dreaded ENOMEM error. This error seems to be more prevalent + under early 2.2.x kernels than under the 2.0.x kernel series. For a given + (large) transfer the memory obtained by this driver must be contiguous or + scatter-gather must be used (if supported by the adapter). [Furthermore, + ISA SCSI adapters can only use memory below the 16MB level on a i386.] + + When a "sg" device is open()ed O_RDWR then this driver will attempt to + reserve a buffer of SG_DEF_RESERVED_SIZE that will be used by subsequent + write()s on this file descriptor as long as: + - it is not already in use (eg when command queuing is in use) + - the write() does not call for a buffer size larger than the + reserved size. + In these cases the write() will attempt to find the memory it needs for + DMA buffers dynamically and in the worst case will fail with ENOMEM. + The amount of memory actually reserved depends on various dynamic factors + and can be checked with the SG_GET_RESERVED_SIZE ioctl(). [In a very + tight memory situation it may yield 0!] The size of the reserved buffer + can be changed with the SG_SET_RESERVED_SIZE ioctl(). It should be + followed with a call to the SG_GET_RESERVED_SIZE ioctl() to find out how + much was actually reserved. - More documentation can be found at www.torque.net/sg + More documentation plus test and utility programs can be found at + http://www.torque.net/sg */ #define SG_MAX_SENSE 16 /* too little, unlikely to change in 2.2.x */ @@ -129,7 +124,7 @@ int pack_len; /* [o] reply_len (ie useless), ignored as input */ int reply_len; /* [i] max length of expected reply (inc. sg_header) */ int pack_id; /* [io] id number of packet (use ints >= 0) */ - int result; /* [o] 0==ok, else (+ve) Unix errno code (e.g. EIO) */ + int result; /* [o] 0==ok, else (+ve) Unix errno (best ignored) */ unsigned int twelve_byte:1; /* [i] Force 12 byte command length for group 6 & 7 commands */ unsigned int target_status:5; /* [o] scsi status from target */ @@ -154,9 +149,9 @@ int unused3; } Sg_scsi_id; -/* ioctls ( _GET_s yield result via 'int *' 3rd argument unless - otherwise indicated */ -#define SG_SET_TIMEOUT 0x2201 /* unit: jiffies, 10ms on i386 */ +/* IOCTLs: ( _GET_s yield result via 'int *' 3rd argument unless + otherwise indicated) */ +#define SG_SET_TIMEOUT 0x2201 /* unit: jiffies (10ms on i386) */ #define SG_GET_TIMEOUT 0x2202 /* yield timeout as _return_ value */ #define SG_EMULATED_HOST 0x2203 /* true for emulated host adapter (ATAPI) */ @@ -165,23 +160,21 @@ #define SG_SET_TRANSFORM 0x2204 #define SG_GET_TRANSFORM 0x2205 -#define SG_SET_RESERVED_SIZE 0x2275 /* currently ignored, future addition */ -/* Following yields buffer reserved by open(): 0 <= x <= SG_SCATTER_SZ */ -#define SG_GET_RESERVED_SIZE 0x2272 +#define SG_SET_RESERVED_SIZE 0x2275 /* request a new reserved buffer size */ +#define SG_GET_RESERVED_SIZE 0x2272 /* actual size of reserved buffer */ /* The following ioctl takes a 'Sg_scsi_id *' object as its 3rd argument. */ -#define SG_GET_SCSI_ID 0x2276 /* Yields fd's bus,chan,dev,lun+type */ +#define SG_GET_SCSI_ID 0x2276 /* Yields fd's bus, chan, dev, lun + type */ /* SCSI id information can also be obtained from SCSI_IOCTL_GET_IDLUN */ -/* Override adapter setting and always DMA using low memory ( <16MB on i386). - Default is 0 (off - use adapter setting) */ +/* Override host setting and always DMA using low memory ( <16MB on i386) */ #define SG_SET_FORCE_LOW_DMA 0x2279 /* 0-> use adapter setting, 1-> force */ #define SG_GET_LOW_DMA 0x227a /* 0-> use all ram for dma; 1-> low dma ram */ /* When SG_SET_FORCE_PACK_ID set to 1, pack_id is input to read() which will attempt to read that pack_id or block (or return EAGAIN).
