* Replace all calls to minor() with dev2unit().Ed Schouten2008-09-271-2/+2
| | | | | | | | | | | | | | | | | | After I removed all the unit2minor()/minor2unit() calls from the kernel yesterday, I realised calling minor() everywhere is quite confusing. Character devices now only have the ability to store a unit number, not a minor number. Remove the confusion by using dev2unit() everywhere. This commit could also be considered as a bug fix. A lot of drivers call minor(), while they should actually be calling dev2unit(). In -CURRENT this isn't a problem, but it turns out we never had any problem reports related to that issue in the past. I suspect not many people connect more than 256 pieces of the same hardware. Reviewed by: kib Notes: svn path=/head/; revision=183397

RIght now, no drivers are MPSAFE, though a few will be changed in the coming week as this work settles down. The driver API has changed, so all CAM drivers will need to be recompiled. The userland API has not changed, so tools like camcontrol do not need to be recompiled. Notes: svn path=/head/; revision=168752

| | | | | | | | | | | | | | | | | | | | | | | | the CAM_NEW_TRAN_CODE that has been in the tree for some years now. This first step consists solely of adding to or correcting CAM_NEW_TRAN_CODE pieces in the kernel source tree such that a both a GENERIC (at least on i386) and a LINT build with CAM_NEW_TRAN_CODE as an option will compile correctly and run (at least with some the h/w I have). After a short settle time, the other pieces (making CAM_NEW_TRAN_CODE the default and updating libcam and camcontrol) will be brought in. This will be an incompatible change in that the size of structures related to XPT_PATH_INQ and XPT_{GET,SET}_TRAN_SETTINGS change in both size and content. However, basic system operation and basic system utilities work well enough with this change. Reviewed by: freebsd-scsi and specific stakeholders Notes: svn path=/head/; revision=163816

* Normalize a significant number of kernel malloc type names:Robert Watson2005-10-311-1/+1
| | | | | | | | | | | | | | | | | | | | | | - Prefer '_' to ' ', as it results in more easily parsed results in memory monitoring tools such as vmstat. - Remove punctuation that is incompatible with using memory type names as file names, such as '/' characters. - Disambiguate some collisions by adding subsystem prefixes to some memory types. - Generally prefer lower case to upper case. - If the same type is defined in multiple architecture directories, attempt to use the same name in additional cases. Not all instances were caught in this change, so more work is required to finish this conversion. Similar changes are required for UMA zone names. Notes: svn path=/head/; revision=151897

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 3ware's 9xxx series controllers. This corresponds to the 9.2 release (for FreeBSD 5.2.1) on the 3ware website. Highlights of this release are: 1. The driver has been re-architected to use a "Common Layer" (all tw_cl* files), which is a consolidation of all OS-independent parts of the driver. The FreeBSD OS specific portions of the driver go into an "OS Layer" (all tw_osl* files). This re-architecture is to achieve better maintainability, consistency of behavior across OS's, and better portability to new OS's (drivers for new OS's can be written by just adding an OS Layer that's specific to the OS, by complying to a "Common Layer Programming Interface" API. 2. The driver takes advantage of multiple processors. 3. The driver has a new firmware image bundled, the new features of which include Online Capacity Expansion and multi-lun support, among others. More details about 3ware's 9.2 release can be found here: http://www.3ware.com/download/Escalade9000Series/9.2/9.2_Release_Notes_Web.pdf Since the Common Layer is used across OS's, the FreeBSD specific include path for header files (/sys/dev/twa) is not part of the #include pre-processor directive in any of the source files. For being able to integrate twa into the kernel despite this, Makefile.<arch> has been changed to add the include path to CFLAGS. Reviewed by: scottl Notes: svn path=/head/; revision=144966
