2009-12-11Staging: virtual block device driver (ramzswap)Nitin Gupta7-0/+1682
Creates RAM based block devices (/dev/ramzswapX) which can be used (only) as swap disks. Pages swapped to these are compressed and stored in memory itself. The module is called ramzswap.ko. It depends on: - xvmalloc memory allocator (compiled with this driver) - lzo_compress.ko - lzo_decompress.ko See ramzswap.txt for usage details.

2009-12-11Staging: xvmalloc memory allocatorNitin Gupta3-0/+623
* Features: - Low metadata overhead (just 4 bytes per object) - O(1) Alloc/Free - except when we have to call system page allocator to get additional memory. - Very low fragmentation: In all tests, xvmalloc memory usage is within 12% of "Ideal". - Pool based allocator: Each pool can grow and shrink. - It maps pages only when required. So, it does not hog vmalloc area which is very small on 32-bit systems. SLUB allocator could not be used due to fragmentation issues: http://code.google.com/p/compcache/wiki/AllocatorsComparison Data here shows kmalloc using ~43% more memory than TLSF and xvMalloc is showed ~2% more space efficiency than TLSF (due to smaller metadata). Creating various kmem_caches can reduce space efficiency gap but still problem of being limited to low memory exists. Also, it depends on allocating higher order pages to reduce fragmentation - this is not acceptable for ramzswap as it is used under memory crunch (its a swap device!). SLOB allocator could not be used do to reasons mentioned here: http://lkml.org/lkml/2009/3/18/210 * Implementation: It uses two-level bitmap search to find free list containing block of correct size. This idea is taken from TLSF (Two-Level Segregate Fit) allocator and is well explained in its paper (see [Links] below). * Limitations: - Poor scalability: No per-cpu data structures (work in progress).

2009-12-11Staging: comedi: pcl816: update convert_src mask for AI cmdtestIan Abbott1-1/+3
The COMEDI_CMDTEST ioctl needs to clear unsupported bits in the struct comedi_cmd's convert_src and other *_src members. This needs fixing in the pcl816 driver's AI cmdtest. Signed-off-by: Ian Abbott <abbotti@mev.co.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-12-11Staging: comedi: initialize divisor variablesIan Abbott6-9/+10
The i8253_cascade_ns_to_timer_2div() function (and i8253_cascade_ns_to_timer macro) checks the old values *d1 and *d2 for correctness as a heuristic before calculating new values. Don't call the function with uninitialized values in *d1 and *d2. Signed-off-by: Ian Abbott <abbotti@mev.co.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-12-11Staging: comedi: serial2002: decrease stack usageIan Abbott1-2/+2
512 bytes of stack can be saved in serial_2002_open() by modifying 'struct config_t'. A short int suffices for the 'kind' and 'bits' members. (Actually, a char would suffice, but wouldn't save any more stack than a short int.) Signed-off-by: Ian Abbott <abbotti@mev.co.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-12-11Staging: comedi: fix usbdux timeout bugBernd Porr1-8/+9
I've fixed a bug in the USBDUX driver which caused timeouts while sending commands to the boards. This was mainly because of one bulk transfer which had a timeout of 1ms (!). I've now set all timeouts to 1000ms. From: Bernd Porr <BerndPorr@f2s.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
