Modified name of two attributes in scsi_host_template. 6 On Wed, 2005-02-02 at 10:56 -0500, Ju, Seokmann wrote: 7 > + .sdev_attrs = megaraid_device_attrs, 8 > + .shost_attrs = megaraid_class_device_attrs, 9 10 These are, perhaps, slightly confusing names. 11 The terms device and class_device have well defined meanings in the 12 generic device model, neither of which is what you mean here. 13 Why not simply megaraid_sdev_attrs and megaraid_shost_attrs? 14 15 Other than this, it looks fine to me too. 16 17Release Date : Thu Jan 27 00:01:03 EST 2005 - Atul Mukker <atulm@lsil.com> 18Current Version : 2.20.4.4 (scsi module), 2.20.2.5 (cmm module) 19Older Version : 2.20.4.3 (scsi module), 2.20.2.4 (cmm module) 20 211. Bump up the version of scsi module due to its conflict. 22 23Release Date : Thu Jan 21 00:01:03 EST 2005 - Atul Mukker <atulm@lsil.com> 24Current Version : 2.20.4.3 (scsi module), 2.20.2.5 (cmm module) 25Older Version : 2.20.4.2 (scsi module), 2.20.2.4 (cmm module) 26 271. Remove driver ioctl for logical drive to scsi address translation and 28 replace with the sysfs attribute. To remove drives and change 29 capacity, application shall now use the device attribute to get the 30 logical drive number for a scsi device. For adding newly created 31 logical drives, class device attribute would be required to uniquely 32 identify each controller. 33 - Atul Mukker <atulm@lsil.com> 34 35 "James, I've been thinking about this a little more, and you may be on 36 to something here. Let each driver add files as such:" 37 38 - Matt Domsch <Matt_Domsch@dell.com>, 12.15.2004 39 linux-scsi mailing list 40 41 42 "Then, if you simply publish your LD number as an extra parameter of 43 the device, you can look through /sys to find it." 44 45 - James Bottomley <James.Bottomley@SteelEye.com>, 01.03.2005 46 linux-scsi mailing list 47 48 49 "I don't see why not ... it's your driver, you can publish whatever 50 extra information you need as scsi_device attributes; that was one of 51 the designs of the extensible attribute system." 52 53 - James Bottomley <James.Bottomley@SteelEye.com>, 01.06.2005 54 linux-scsi mailing list 55 562. Add AMI megaraid support - Brian King <brking@charter.net> 57 PCI_VENDOR_ID_AMI, PCI_DEVICE_ID_AMI_MEGARAID3, 58 PCI_VENDOR_ID_AMI, PCI_SUBSYS_ID_PERC3_DC, 59 603.

Fixed Tape drive issue : For any Direct CDB command to physical device 74 including tape, timeout value set by driver was 10 minutes. With this 75 value, most of command will return within timeout. However, for those 76 command like ERASE or FORMAT, it takes more than an hour depends on 77 capacity of the device and the command could be terminated before it 78 completes. 79 To address this issue, the 'timeout' field in the DCDB command will 80 have NO TIMEOUT (i.e., 4) value as its timeout on DCDB command. 81 82 83 84Release Date : Thu Dec 9 19:10:23 EST 2004 85 - Sreenivas Bagalkote <sreenib@lsil.com> 86 87Current Version : 2.20.4.2 (scsi module), 2.20.2.4 (cmm module) 88Older Version : 2.20.4.1 (scsi module), 2.20.2.3 (cmm module) 89 90i. Introduced driver ioctl that returns scsi address for a given ld. 91 92 "Why can't the existing sysfs interfaces be used to do this?" 93 - Brian King (brking@us.ibm.com) 94 95 "I've looked into solving this another way, but I cannot see how 96 to get this driver-private mapping of logical drive number-> HCTL 97 without putting code something like this into the driver." 98 99 "...and by providing a mapping a function to userspace, the driver 100 is free to change its mapping algorithm in the future if necessary .." 101 - Matt Domsch (Matt_Domsch@dell.com) 102 103Release Date : Thu Dec 9 19:02:14 EST 2004 - Sreenivas Bagalkote <sreenib@lsil.com> 104 105Current Version : 2.20.4.1 (scsi module), 2.20.2.3 (cmm module) 106Older Version : 2.20.4.1 (scsi module), 2.20.2.2 (cmm module) 107 108i.

Handle IOCTL cmd timeouts more properly. 116 117ii. pci_dma_sync_{sg,single}_for_cpu was introduced into megaraid_mbox 118 incorrectly (instead of _for_device). Changed to appropriate 119 pci_dma_sync_{sg,single}_for_device. 120 121Release Date : Wed Oct 06 11:15:29 EDT 2004 - Sreenivas Bagalkote <sreenib@lsil.com> 122Current Version : 2.20.4.0 (scsi module), 2.20.2.1 (cmm module) 123Older Version : 2.20.4.0 (scsi module), 2.20.2.0 (cmm module) 124 125i. Remove CONFIG_COMPAT around register_ioctl32_conversion 126 127Release Date : Mon Sep 27 22:15:07 EDT 2004 - Atul Mukker <atulm@lsil.com> 128Current Version : 2.20.4.0 (scsi module), 2.20.2.0 (cmm module) 129Older Version : 2.20.3.1 (scsi module), 2.20.2.0 (cmm module) 130 131i. Fix data corruption. Because of a typo in the driver, the IO packets 132 were wrongly shared by the ioctl path. This causes a whole IO command 133 to be replaced by an incoming ioctl command. 134 135Release Date : Tue Aug 24 09:43:35 EDT 2004 - Atul Mukker <atulm@lsil.com> 136Current Version : 2.20.3.1 (scsi module), 2.20.2.0 (cmm module) 137Older Version : 2.20.3.0 (scsi module), 2.20.2.0 (cmm module) 138 139i. Function reordering so that inline functions are defined before they 140 are actually used. It is now mandatory for GCC 3.4.1 (current stable) 141 142 Declare some heavy-weight functions to be non-inlined, 143 megaraid_mbox_build_cmd, megaraid_mbox_runpendq, 144 megaraid_mbox_prepare_pthru, megaraid_mbox_prepare_epthru, 145 megaraid_busywait_mbox 146 147 - Andrew Morton <akpm@osdl.org>, 08.19.2004 148 linux-scsi mailing list 149 150 "Something else to clean up after inclusion: every instance of an 151 inline function is actually rendered as a full function call, because 152 the function is always used before it is defined. Atul, please 153 re-arrange the code to eliminate the need for most (all) of the 154 function prototypes at the top of each file, and define (not just 155 declare with a prototype) each inline function before its first use" 156 157 - Matt Domsch <Matt_Domsch@dell.com>, 07.27.2004 158 linux-scsi mailing list 159 160 161ii. Display elapsed time (countdown) while waiting for FW to boot. 162 163iii. Module compilation reorder in Makefile so that unresolved symbols do 164 not occur when driver is compiled non-modular. 165 166 Patrick J. LoPresti <patl@users.sourceforge.net>, 8.22.2004 167 linux-scsi mailing list 168 169 170Release Date : Thu Aug 19 09:58:33 EDT 2004 - Atul Mukker <atulm@lsil.com> 171Current Version : 2.20.3.0 (scsi module), 2.20.2.0 (cmm module) 172Older Version : 2.20.2.0 (scsi module), 2.20.1.0 (cmm module) 173 174i. When copying the mailbox packets, copy only first 14 bytes (for 32-bit 175 mailboxes) and only first 22 bytes (for 64-bit mailboxes). This is to 176 avoid getting the stale values for busy bit. We want to set the busy 177 bit just before issuing command to the FW. 178 179ii. In the reset handling, if the reseted command is not owned by the 180 driver, do not (wrongly) print information for the "attached" driver 181 packet. 182 183iii. Have extended wait when issuing command in synchronous mode. This is 184 required for the cases where the option ROM is disabled and there is 185 no BIOS to start the controller. The FW starts to boot after receiving 186 the first command from the driver. The current driver has 1 second 187 timeout for the synchronous commands, which is far less than what is 188 actually required. We now wait up to MBOX_RESET_TIME (180 seconds) for 189 FW boot process. 190 191iv. In megaraid_mbox_product_info, clear the mailbox contents completely 192 before preparing the command for inquiry3. This is to ensure that the 193 FW does not get junk values in the command. 194 195v. Do away with the redundant LSI_CONFIG_COMPAT redefinition for 196 CONFIG_COMPAT. Replace <asm/ioctl32.h> with <linux/ioctl32.h> 197 198 - James Bottomley <James.Bottomley@SteelEye.com>, 08.17.2004 199 linux-scsi mailing list 200 201vi. Add support for 64-bit applications. Current drivers assume only 202 32-bit applications, even on 64-bit platforms. Use the "data" and 203 "buffer" fields of the mimd_t structure, instead of embedded 32-bit 204 addresses in application mailbox and passthru structures. 205 206vii. Move the function declarations for the management module from 207 megaraid_mm.h to megaraid_mm.c 208 209 - Andrew Morton <akpm@osdl.org>, 08.19.2004 210 linux-scsi mailing list 211 212viii. Change default values for MEGARAID_NEWGEN, MEGARAID_MM, and 213 MEGARAID_MAILBOX to 'n' in Kconfig.megaraid 214 215 - Andrew Morton <akpm@osdl.org>, 08.19.2004 216 linux-scsi mailing list 217 218ix. replace udelay with msleep 219 220x. Typos corrected in comments and whitespace adjustments, explicit 221 grouping of expressions. 222 223 224Release Date : Fri Jul 23 15:22:07 EDT 2004 - Atul Mukker <atulm@lsil.com> 225Current Version : 2.20.2.0 (scsi module), 2.20.1.0 (cmm module) 226Older Version : 2.20.1.0 (scsi module), 2.20.0.0 (cmm module) 227 228i. Add PCI ids for Acer ROMB 2E solution 229 230ii. Add PCI ids for I4 231 232iii. Typo corrected for subsys id for megaraid sata 300-4x 233 234iv. Remove yield() while mailbox handshake in synchronous commands 235 236 237 "My other main gripe is things like this: 238 239 + // wait for maximum 1 second for status to post 240 + for (i = 0; i < 40000; i++) { 241 + if (mbox->numstatus != 0xFF) break; 242 + udelay(25); yield(); 243 + } 244 245 which litter the driver. Use of yield() in drivers is deprecated." 246 247 - James Bottomley <James.Bottomley@SteelEye.com>, 07.14.2004 248 linux-scsi mailing list 249 250v. Remove redundant __megaraid_busywait_mbox routine 251 252vi. Fix bug in the managment module, which causes a system lockup when the 253 IO module is loaded and then unloaded, followed by executing any 254 management utility. The current version of management module does not 255 handle the adapter unregister properly. 256 257 Specifically, it still keeps a reference to the unregistered 258 controllers. To avoid this, the static array adapters has been 259 replaced by a dynamic list, which gets updated every time an adapter 260 is added or removed. 261 262 Also, during unregistration of the IO module, the resources are 263 now released in the exact reverse order of the allocation time 264 sequence. 265 266 267Release Date : Fri Jun 25 18:58:43 EDT 2004 - Atul Mukker <atulm@lsil.com> 268Current Version : 2.20.1.0 269Older Version : megaraid 2.20.0.1 270 271i. Stale list pointer in adapter causes kernel panic when module 272 megaraid_mbox is unloaded 273 274 275Release Date : Thu Jun 24 20:37:11 EDT 2004 - Atul Mukker <atulm@lsil.com> 276Current Version : 2.20.0.1 277Older Version : megaraid 2.20.0.00 278 279i. Modules are not 'y' by default, but depend on current definition of 280 SCSI & PCI. 281 282ii. Redundant structure mraid_driver_t removed. 283 284iii. Miscellaneous indentation and goto/label fixes. 285 - Christoph Hellwig <hch@infradead.org>, 06.24.2004 linux-scsi 286 287iv. scsi_host_put(), do just before completing HBA shutdown. 288 289 290 291Release Date : Mon Jun 21 19:53:54 EDT 2004 - Atul Mukker <atulm@lsil.com> 292Current Version : 2.20.0.0 293Older Version : megaraid 2.20.0.rc2 and 2.00.3 294 295i. Independent module to interact with userland applications and 296 multiplex command to low level RAID module(s). 297 298 "Shared code in a third module, a "library module", is an acceptable 299 solution. modprobe automatically loads dependent modules, so users 300 running "modprobe driver1" or "modprobe driver2" would automatically 301 load the shared library module." 302 303 - Jeff Garzik <jgarzik@pobox.com> 02.25.2004 LKML 304 305 "As Jeff hinted, if your userspace<->driver API is consistent between 306 your new MPT-based RAID controllers and your existing megaraid driver, 307 then perhaps you need a single small helper module (lsiioctl or some 308 better name), loaded by both mptraid and megaraid automatically, which 309 handles registering the /dev/megaraid node dynamically. In this case, 310 both mptraid and megaraid would register with lsiioctl for each 311 adapter discovered, and lsiioctl would essentially be a switch, 312 redirecting userspace tool ioctls to the appropriate driver." 313 314 - Matt Domsch <Matt_Domsch@dell.com> 02.25.2004 LKML 315 316ii. Remove C99 initializations from pci_device id. 317 318 "pci_id_table_g would be much more readable when not using C99 319 initializers. 320 PCI table doesn't change, there's lots of users that prefer the more 321 readable variant. And it's really far less and much easier to grok 322 lines without C99 initializers." 323 324 - Christoph Hellwig <hch@infradead.org>, 05.28.2004 linux-scsi 325 326iii. Many fixes as suggested by Christoph Hellwig <hch@infradead.org> on 327 linux-scsi, 05.28.2004 328 329iv. We now support up to 32 parallel ioctl commands instead of current 1. 330 There is a conscious effort to let memory allocation not fail for ioctl 331 commands. 332 333v. Do away with internal memory management. Use pci_pool_(create|alloc) 334 instead. 335 336vi. Kill tasklet when unloading the driver. 337 338vii. Do not use "host_lock', driver has fine-grain locks now to protect all 339 data structures. 340 341viii. Optimize the build scatter-gather list routine. The callers already 342 know the data transfer address and length. 343 344ix. Better implementation of error handling and recovery. Driver now 345 performs extended errors recovery for instances like scsi cable pull. 346 347x. Disassociate the management commands with an overlaid scsi command. 348 Driver now treats the management packets as special packets and has a 349 dedicated callback routine. 350
