* edac: e752x: add dram scrubbing supportPeter Tyser2010-03-131-0/+107
| | | | | | | | | | | | | | | | | | | | | | Add support to scrub DRAM using the e752x integrated memory scrubbing engine. The e7320/7520/e7525 chipsets support scrubbing at one rate while the i3100 chipset supports a normal and fast rate. A similar patch was originally sent back in 2008: http://sourceforge.net/mailarchive/forum.php?thread_name=1204835866.25206.70.camel@localhost.localdomain&forum_name=bluesmoke-devel This version has the following updates: - Use 16-bit PCI config cycles to access MCHSCRB register e7320/7520/e7525 docs say register is 16bits wide, i3100 says 8. I tested 16bits on the i3100 to be safe. - Recalcuate and round actual scrub rates The changes have been tested on an i3100-based board.

* edac: mpc85xx improve SDRAM error reportingPeter Tyser2010-03-131-8/+138
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the ability to detect the specific data line or ECC line which failed when printing out SDRAM single-bit errors. An example of a single-bit SDRAM ECC error is below: EDAC MPC85xx MC1: Err Detect Register: 0x80000004 EDAC MPC85xx MC1: Faulty data bit: 59 EDAC MPC85xx MC1: Expected Data / ECC: 0x7f80d000_409effa0 / 0x6d EDAC MPC85xx MC1: Captured Data / ECC: 0x7780d000_409effa0 / 0x6d EDAC MPC85xx MC1: Err addr: 0x00031ca0 EDAC MPC85xx MC1: PFN: 0x00000031 Knowning which specific data or ECC line caused an error can be useful in tracking down hardware issues such as improperly terminated signals, loose pins, etc. Note that this feature is only currently enabled for 64-bit wide data buses, 32-bit wide bus support should be added. I don't have any 32-bit wide systems to test on. If someone has one and is willing to give this patch a shot with the check for a 64-bit data bus removed it would be much appreciated and I can re-submit with both 32 and 64 bit buses supported.

* edac: mpc85xx mask ecc syndrome correctlyPeter Tyser2010-03-132-1/+14
| | | | | | | | | | | | | | | | | | | | | | | | | With a 64-bit wide data bus only the lowest 8-bits of the ECC syndrome are relevant. With a 32-bit wide data bus only the lowest 16-bits are relevant on most architectures. Without this change, the ECC syndrome displayed can be mildly confusing, eg: EDAC MPC85xx MC1: syndrome: 0x25252525 When in reality the ECC syndrome is 0x25. A variety of Freescale manuals say a variety of different things about how to decode the CAPTURE_ECC (syndrome) register. I don't have a system with a 32-bit bus to test on, but I believe the change is correct. It'd be good to get an ACK from someone at Freescale about this change though.

* broadsheetfb: support storing waveformJaya Kumar2010-03-131-1/+500
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds waveform storing capability to broadsheetfb. It uses the firmware class to retrieve the waveform, and the request to initiate the waveform storing is done via a driver sysfs entry, loadstore_waveform. Broadsheet is a framebuffer device. It is slightly different from a typical framebuffer controller that drives a normal TFT-LCD display. Most E-Ink display panels require a waveform in order to function. That is, in order to drive the state of a pixel to black, gray, or white, a specific waveform is utilized. Basically, that waveform represents the specific E-field wiggling needed to get the pixel to its optimal state given current temperature, and its previous state. TN/IPS-LCDs use a similar concept but the driving waveform is sufficiently simple that it is internalized in the TFT source/gate driver. These E-Ink waveforms are specific to a production batch. That is, a batch of display films are produced, then they get characterized and a waveform is generated for that batch. Broadsheet, typically, is attached to its private SPI flash which is then flashed with this waveform. Users won't be able to see the waveform and typically won't ever need to know about it. If however, the display panel attached to broadsheet is changed out, then they will need to update their waveform. That would typically be done at a factory or repair facility rather than by a user.

* viafb: support color depth 15 and 30Florian Tobias Schandinat2010-03-132-18/+34
| | | | | | | | | | | | | | | | | | | | | Add support for the color depth 15 on IGA1 and 30 on IGA1 and IGA2. To allow the usage of those the driver now refuses color depth that are totally off and otherwise the selection in viafb_check_var is used. Therefore the first call to this for the first framebuffer was delayed a bit. It only enables the new formats if they are requested exactly (viafb_bpp=15|30). As this is a new feature, no regressions are expected. The color depth 15 was successfully tested. Didn't get anything usable for 30 but that might be the programs fault. I would like to get some feedback whether it works as expected or not if somebody knows a program/configuration where it should.

* viafb: rework color settingFlorian Tobias Schandinat2010-03-133-216/+51
| | | | | | | | | | | | | | | | | | | | | This is a rewritten version of viafb_setcolreg. The hardware register writes were split up and moved to hw.c where they belong as this is really low level stuff. It was made dual fb aware. Furthermore viafb_setcmap was removed as the problem with 8bpp originated from a bug in writing multiple color registers at once. The removal of viafb_setcmap might introduce a small performance regression but its certainly better to receive the correct result a bit slower than a garbled picture fast. It should give us a working 8bpp mode and is more extensible than the old hardcoded code. No other regressions are expected but as the hardware might be a bit picky it might cause some regressions in 8bpp mode on some hardware although I doubt that.

It splits the filling of the color information in var to a seperate function and sets some color related values in var that where previously untouched.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is an attempt to make viafb_set_par work correctly with more than one framebuffer. As modesetting is not (yet/easily) possible for each individual IGA it uses the (normally to be avoided) global variables viafbinfo{,1} to ensure that each function is called with the correct values. This patch (finally) allows usable dual framebuffer setups and should not affect non dual fb ones. It works in some (most?) configurations as sometimes the driver still gets device connections wrong. It can be worth to try the devices in reverse order (in viafb_active_dev). The user experience is still not very nice as: - on the second fb you'll normally have a garbled picture as long as no application draws to it goal: auto on/off devices depending on reference counting - as the whole machinery is always done you can see mode changes also in an unaffected framebuffer goal: split modesetting up for each individual IGA Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de> Cc: Scott Fang <ScottFang@viatech.com.cn> Cc: Joseph Chan <JosephChan@via.com.tw> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

For SAMM without dual fb this might break something as I really cannot image what we are supposed to do for different resolutions with a single framebuffer as we can't get data out of nowhere (no, they are not set up in something one would call "expanded"). Previously I got for that funny colored pictures as the second IGA pointed to video memory that was never written to. After the patch it'll work as cloning if the first and second mode are identical (this was working already without SAMM). Finally for dual fb this should push us a step in the right direction.

* viafb: split global index upFlorian Tobias Schandinat2010-03-139-386/+225
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the first step to remove an artificial global index that was used in two ways: 1. As a pseudo index in the mode table. Pseudo as you had to search through the table to find the referenced entry. This was replaced by using a pointer to the entry. 2. As a shortcut to compare a combination of horizontal and vertical resolution at the same time. This was replaced by a "(hres<<16) | vres" which is good enough for now and the near future. If vres or hres become greater than 2^16 this might indeed cause problems but this solution allows to split this indexing mess up without the requirement to do even more code changes. This is a big change that will allow more clean ups. It should be a bit faster but that is probably not relevant for normal operation. No regressions expected but as this is a relatively big step heavy testing is appreciated.
