* drivers/md: use time_before, time_before_eq, etcJulia Lawall2008-04-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The functions time_before, time_before_eq, time_after, and time_after_eq are more robust for comparing jiffies against other values.

* raid: remove leading TAB on printk messagesNick Andrew2008-04-28
| | | | | | | | | | | | | | | | MD drivers use one printk() call to print 2 log messages and the second line may be prefixed by a TAB character. It may also output a trailing space before newline. klogd (I think) turns the TAB character into the 2 characters '^I' when logging to a file. This looks ugly. Instead of a leading TAB to indicate continuation, prefix both output lines with 'raid:' or similar. Also remove any trailing space in the vicinity of the affected code and consistently end the sentences with a period.

* md: introduce get_priority_stripe() to improve raid456 write performanceDan Williams2008-04-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Improve write performance by preventing the delayed_list from dumping all its stripes onto the handle_list in one shot. Delayed stripes are now further delayed by being held on the 'hold_list'. The 'hold_list' is bypassed when: * a STRIPE_IO_STARTED stripe is found at the head of 'handle_list' * 'handle_list' is empty and i/o is being done to satisfy full stripe-width write requests * 'bypass_count' is less than 'bypass_threshold'. By default the threshold is 1, i.e. every other stripe handled is a preread stripe provided the top two conditions are false. Benchmark data: System: 2x Xeon 5150, 4x SATA, mem=1GB Baseline: 2.6.24-rc7 Configuration: mdadm --create /dev/md0 /dev/sd[b-e] -n 4 -l 5 --assume-clean Test1: dd if=/dev/zero of=/dev/md0 bs=1024k count=2048 * patched: +33% (stripe_cache_size = 256), +25% (stripe_cache_size = 512) Test2: tiobench --size 2048 --numruns 5 --block 4096 --block 131072 (XFS) * patched: +13% * patched + preread_bypass_threshold = 0: +37% Changes since v1: * reduce bypass_threshold from (chunk_size / sectors_per_chunk) to (1) and make it configurable. This defaults to fairness and modest performance gains out of the box. Changes since v2: * [neilb@suse.de]: kill STRIPE_PRIO_HI and preread_needed as they are not necessary, the important change was clearing STRIPE_DELAYED in add_stripe_bio and this has been moved out to make_request for the hang fix. * [neilb@suse.de]: simplify get_priority_stripe * [dan.j.williams@intel.com]: reset the bypass_count when ->hold_list is sampled empty (+11%) * [dan.j.williams@intel.com]: decrement the bypass_count at the detection of stripes being naturally promoted off of hold_list +2%. Note, resetting bypass_count instead of decrementing on these events yields +4% but that is probably too aggressive. Changes since v3: * cosmetic fixups Tested-by: James W.

| | | | | | | | | | | | | | | | | | | | | 965G/965GM Add support for the 965G and 965GM graphic chipsets to the intelfb driver. I have a notebook with an Intel Mobile GM965/GL960 Integrated Graphics Controller and with the attached patch the framebuffer comes up. I have tested it a bit with DirectFB to make sure it is working stable. I also have an Intel Mobile GM945 and I compared the results, the programming interface of the 9xx series from Intel is mostly the same, so I think the patch should add all the functionality which the 945GM has.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following features are supported: plane 0 works as a regular frame buffer, can be accessed by /dev/fb0 plane 1 has two AOIs (area of interest), can be accessed by /dev/fb1 and /dev/fb2 plane 2 has two AOIs, can be accessed by /dev/fb3 and /dev/fb4 Special ioctls support AOIs All /dev/fb* can be used as regular frame buffer devices, except hardware change can only be made through /dev/fb0. Changing pixel clock has no effect on other fbs. Limitation of usage of AOIs: AOIs on the same plane can not be horizonally overlapped AOIs have horizonal order, i.e. AOI0 should be always on top of AOI1 AOIs can not beyond phisical display area. Application should check AOI geometry before changing physical resolution on /dev/fb0 required command line parameters to preallocate memory for frame buffer diufb. optional command line parameters to set modes and monitor video=fslfb:[resolution][,bpp][,monitor] Syntax: Resolution xres x yres-bpp@refresh_rate, the -bpp and @refresh_rate are optional eg, 1024x768, 1280x1024, 1280x1024-32, 1280x1024@60, 1280x1024-32@60, 1280x480-32@60 Bpp bpp=32, bpp=24, or bpp=16 Monitor monitor=0, monitor=1, monitor=2 0 is DVI 1 is Single link LVDS 2 is Double link LVDS Note: switching monitor is a board feather, not DIU feather. MPC8610HPCD has three monitor ports to swtich to. MPC5121ADS doesn't have additional monitor port. So switching monirot port for MPC5121ADS has no effect. If compiled as a module, it takes pamameters mode, bpp, monitor with the same syntax above.

* OLPC: gxfb/lxfb: add DCON panel modes to framebuffer driversAndres Salomon2008-04-28
| | | | | | | | | | | | | | | | | Since there's no way to autodetect panel modes, we're forced to hardcode them in the driver and add a big fat #ifdef. The OLPC DCON needs a specific mode line (at 1200x900). This adds it to both gxfb and lxfb. (Jordan said: We could probably detect the panel mode, but there isn't any reason to since the panel timings are well known and won't change. While OFW detection would be good computer science fu, it would be a wasted effort since its so easy to hard code them into the table.)

* atmel_lcdfb: wiring BGR to RGB color modeNicolas Ferre2008-04-28
| | | | | | | | | | | | | | | | | | | | | | Adds different wiring mode for the LCD screen. The legacy atmel LCDC IP uses a non standard color mode, "BGR-555.1" instead "RGB-565". The major part of graphic stacks for embedded systems uses only "RGB-565". It is possible to swap LCD IOs instead of doing this bit swapping by software (See application note AT91SAM9 LCD Controller http://www.atmel.com/dyn/resources/prod_documents/doc6300.pdf) This wire swapping is done on the at91sam9rl-ek board (board code using this patch will come later).

* atmel_lcdfb: suspend/resume supportDavid Brownell2008-04-28
| | | | | | | | | | | | | | | | | | Teach atmel_lcdfb driver how to suspend/resume. Note that the backlight control should probably do more of the same stuff: turning off display power (more than just the backlight) and stopping the clocks (and dma to drive the no-longer-seen display). No point in wasting power to generate images that can't be observed, after all...

* atmel_lcdfb: don't initialize a pre-allocated framebufferHaavard Skinnemoen2008-04-28
| | | | | | | | | | | | | | | | | | | | | | If the user specified a fixed framebuffer address on the command line, it may have been initialized already with a splash image or something, so we shouldn't clear it. Therefore, we should only initialize the framebuffer if we allocated it ourselves. This patch also updates the AVR32 setup code to clear the framebuffer if it allocated it itself, i.e. the user didn't provide a fixed address or the reservation failed. I've updated the at91 platform code as well so that it initializes the framebuffer if it is located in SRAM, but I haven't tested that it actually works.

| | | | | | | | | | | | There is no reason to drive the savagefb I2C bus at such a low speed, so bump it from 12.5 kbps to 50 kbps. The Intel (i810) and Matrox framebuffer drivers already run their I2C bus at this speed, and so are the legacy i2c-savage4 and i2c-prosavage drivers.

* uvesafb: don't treat valid modes returned byfb_find_mode() as errorsMichal Januszewski2008-04-28
| | | | | | | | | | | | | | | Don't treat valid modes returned by fb_find_mode() (best-fit modes, default modes or the first valid mode) as errors. Currently, when fb_find_mode() finds a valid mode belonging to one of the above-mentioned classes, uvesafb will ignore it and will try to set a 640x480 video mode. The expected behaviour (introduced by this patch) would be to use the valid mode returned by fb_find_mode() instead. Signed-off-by: Michal Januszewski <spock@gentoo.org> Cc: "Antonino A.
