2010-03-12broadsheetfb: support storing waveformJaya Kumar
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.

2010-03-12viafb: support color depth 15 and 30Florian Tobias Schandinat
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.

2010-03-12viafb: rework color settingFlorian Tobias Schandinat
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.

2010-03-12viafb: rework color checkingFlorian Tobias Schandinat
Make color checking a bit more tolerant in what values it allows and more fine grained to later support 15 and 30 bits formats. 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 could be a bug fix but at least I don't know any applications that was fooled by not correctly setting the fields in var. At least no regressions are expected.

2010-03-12viafb: remove dead code due to IGA1_IGA2Florian Tobias Schandinat
Some code depended on IGA1_IGA2 which was never set (at least with the symbolic name). Remove this dead code although it might one day be useful to get a hint on how some things might work. However as this is dead it is likely full of bugs and would prevent a clean structure (as it has some very strange things). Dead code -> no regressions, at least if VIA doesn't do anything very ugly.

2010-03-12viafb: split color mode setting upFlorian Tobias Schandinat
This patch splits color mode setting up in seperate functions. Some hardware initialization that was previously mixed with it is moved to viafb_setmode. As are the calls to the newly created function. This is yet another little step towards controlling each IGA on its own. As this patch really aims too mimic the old behaviour no regressions are expected. However I noticed that 8bpp (or 6bpp?) seems actually a bit broken before and after the patch.

2010-03-12viafb: make viafb_set_par more dual framebuffer compatibleFlorian Tobias Schandinat
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>
2010-03-12viafb: video address setting revisitedFlorian Tobias Schandinat
Set always the correct video address. Especially do panning right on multiple IGAs. This should have no effect on single monitor mode (no SAMM, no dual fb). 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.

This should have no effect on non dual framebuffer mode and do what the user intended (initalization to desired modes) in dual framebuffer mode.

2010-03-12viafb: split global index upFlorian Tobias Schandinat
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.

2010-03-07platform-drivers: move probe to .devinit.text in drivers/videoUwe Kleine-König
A pointer to a probe callback is passed to the core via platform_driver_register and so the function must not disappear when the .init sections are discarded. Otherwise (if also having HOTPLUG=y) unbinding and binding a device to the driver via sysfs will result in an oops as does a device being registered late. An alternative to this patch is using platform_driver_probe instead of platform_driver_register plus removing the pointer to the probe function from the struct platform_driver.

Constify struct sysfs_ops. This is part of the ops structure constification effort started by Arjan van de Ven et al. Benefits of this constification: * prevents modification of data that is shared (referenced) by many other structure instances at runtime * detects/prevents accidental (but not intentional) modification attempts on archs that enforce read-only kernel data at runtime * potentially better optimized code as the compiler can assume that the const data cannot be changed * the compiler/linker move const data into .rodata and therefore exclude them from false sharing Signed-off-by: Emese Revfy <re.emese@gmail.com> Acked-by: David Teigland <teigland@redhat.com> Acked-by: Matt Domsch <Matt_Domsch@dell.com> Acked-by: Maciej Sosnowski <maciej.sosnowski@intel.com> Acked-by: Hans J.

2010-03-06console: limit the range of VGACON_SOFT_SCROLLBACK_SIZEAmerigo Wang
BuraphaLinux reported that we will trigger a mm warning when we CONFIG_VGACON_SOFT_SCROLLBACK_SIZE=65536, this is because mm cann't allocate so many pages. We should limit the range of CONFIG_VGACON_SOFT_SCROLLBACK_SIZE, don't give a user any chance to trigger that.

2010-03-01vga_switcheroo: initial implementation (v15)Dave Airlie
Many new laptops now come with 2 gpus, one to be used for low power modes and one for gaming/on-ac applications. These GPUs are typically wired to the laptop panel and VGA ports via a multiplexer unit which is controlled via ACPI methods. 4 combinations of systems typically exist - with 2 ACPI methods. Intel/ATI - Lenovo W500/T500 - use ATPX ACPI method ATI/ATI - some ASUS - use ATPX ACPI Method Intel/Nvidia - - use _DSM ACPI method Nvidia/Nvidia - - use _DSM ACPI method. TODO: This patch adds support for the ATPX method and initial bits for the _DSM methods that need to written by someone with access to the hardware. Add a proper non-debugfs interface - need to get some proper testing first. v2: add power up/down support for both devices on W500 puts i915/radeon into D3 and cuts power to radeon. v3: redo probing methods, no DMI list, drm devices call to register with switcheroo, it tries to find an ATPX method on any device and once there is two devices + ATPX it inits the switcher. v4: ATPX msg handling using buffers - should work on more machines v5: rearchitect after more mjg59 discussion - move ATPX handling to radeon driver. v6: add file headers + initial nouveau bits (to be filled out). v7: merge delayed switcher code. v8: avoid suspend/resume of gpu that is off v9: rearchitect - mjg59 is always right. - move all ATPX code to radeon, should allow simpler DSM also proper ATRM handling v10: add ATRM support for radeon BIOS, add mutex to lock vgasr_priv v11: fix bug in resuming Intel for 2nd time. v12: start fixing up nvidia code blindly. v13: blindly guess at finishing nvidia code v14: remove radeon audio hacks - fix up intel resume more like upstream v15: clean up printks + remove unnecessary igd/dis pointers mount debugfs /sys/kernel/debug/vgaswitcheroo/switch - should exist if ATPX detected + 2 cards. DIS - immediate change to discrete IGD - immediate change to IGD DDIS - delayed change to discrete DIGD - delayed change to IGD ON - turn on not in use OFF - turn off not in use Tested on W500 (Intel/ATI) and T500 (Intel/ATI) Signed-off-by: Dave Airlie <airlied@redhat.com>
