| Version 4.2.2 |
| 22 July 2011 |
| -add progress message for one more errno value (EAGAIN) in response to failed |
| mlock; BSDs use this to indicate the lock failed due to being over a system |
| or process limit, much like ENOMEM. |
| |
| Version 4.2.1 |
| 3 October 2010 |
| -fix offsets/addresses were not being reported correctly in test failure |
| messages. Thanks: Anton Sergeev. |
| |
| Version 4.2.0 |
| 30 July 2010 |
| -define _FILE_OFFSET_BITS to 64 by default in conf-cc, which causes some |
| 32-bit systems with larger-than-32-bit address spaces to have a 64-bit off_t, |
| allowing testing of larger chunks of memory. Thanks to Steven A. Falco for |
| the suggestion. Let me know if this definition causes problems for anyone. |
| -add tests of 8-bit-wide and 16-bit-wide random writes, to enable verifying |
| the correct operation of hardware. Thanks: Dick Hollenbeck. If these tests |
| trigger unaligned access problems on your platform, you can eliminate these |
| tests by removing the -DTEST_NARROW_WRITES definition from the conf-cc file. |
| |
| Version 4.1.3 |
| 28 February 2010 |
| -fix 64-bit data patterns with some versions of gcc. Thanks: Tony Battersby. |
| -clarify `make install` in readme. Thanks: Marc Lobelle. |
| |
| Version 4.1.2 |
| 28 July 2009 |
| -fix portability issue with MAP_LOCKED flag. Thanks: Scott Haneda. |
| -remove debugging output accidentally left in v.4.1.0. |
| -cleanups |
| |
| Version 4.1.1 |
| 24 July 2009 |
| |
| -memtester.h was missing from the 4.1.0 tarball; release update to fix that. |
| Thanks: Owen Leonard. |
| |
| Version 4.1.0 |
| 23 July 2009 |
| |
| -added the ability to test a specific physical region of memory (by mmap'ing |
| /dev/mem) with the new -p option, which takes a hex starting address as a |
| value. This is mostly of use to developers trying to verify memory or I/O |
| mapped devices (on an embedded system, for instance). Thanks: Allon Stern. |
| -re-add the ability to set a suffix on the memory to allocate: "3G", "128K", etc, |
| mostly for use with the above new feature, where the "memory" to be tested is |
| less than a megabyte, but also useful for users wanting to test many gigabytes; |
| you no longer have to do the conversion-to-megs in your head. |
| -documentation updates and clarifications. |
| |
| Version 4.0.8 |
| 21 November 2007 |
| |
| -add a startup check for amount of memory being greater than the possible |
| address space; prevents user confusion on 32-bit systems that use addressing |
| tricks to have >4GB total system memory. Thanks: Michael Kelly. |
| -documentation updates |
| |
| Version 4.0.7 |
| 13 May 2007 |
| |
| -fix a bug in the align-to-page logic which may have prevented memtester |
| from mlock()ing the memory it was trying to test on some systems. |
| Thanks: Baif Chen. |
| |
| Version 4.0.6 |
| 15 November 2006 |
| |
| -test algorithm improvement: the walking 0 bits test was only walking |
| the 0 bit in one direction, instead of walking it up and back down |
| the line the way it was intended to. Thanks: Tim Rule. |
| -formatting cleanups. |
| |
| Version 4.0.5 |
| 10 March 2005 |
| |
| -change to the method of allocating and locking memory; if we get EPERM |
| when trying to mlock(), reset the amount of memory desired to the original |
| amount and try again without mlock(). The reason for this is that on many |
| systems, mlock() won't return EPERM until after having returned ENOMEM for |
| a larger amount. The new behaviour allows processes without mlock privileges |
| to still test the fully-specified amount or as much memory as can be |
| allocated. Thanks for the suggestion and testing to Dan Bradley. |
| |
| Version 4.0.4 |
| 26 August 2004 |
| |
| -make memtester's exit code meaningful. See the manpage for its meaning. |
| Thanks to Wurzel Parsons-Keir, who sent a patch for the code, so I only had |
| to document it. |
| |
| Version 4.0.3 |
| 10 August 2004 |
| |
| -small changes to enable building with dietlibc and a few other environments |
| that don't even attempt to provide the various Posix definitions. |
| -cosmetic fixes to output. |
| -restore the reduce-and-retry loop of memory locking from version 2. |
| |
| Version 4.0.2 |
| 9 August 2004 |
| |
| -add manpage |
| |
| Version 4.0.1 |
| 8 August 2004 |
| |
| -fix cosmetic bugs in output |
| |
| Version 4.0.0 |
| 7 August 2004 |
| |
| -rewrite to clean up the code (previously an ugly hack), for 64-bit |
| cleanliness |
| -change build system to build on (hopefully) any platform. Previous |
| versions required hackery on some systems. |
| |
| Version 3 not publicly released. |
