* video: sh_mobile_lcdcfb deferred io supportMagnus Damm2008-12-22
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds sh_mobile_lcdcfb deferred io support for SYS panels. The LCDC hardware block managed by the sh_mobile_lcdcfb driver supports RGB or SYS panel configurations. SYS panels come with an external display controller that is resposible for refreshing the actual LCD panel. RGB panels are controlled directly by the LCDC and they need to be refreshed by the LCDC hardware. In the case of SYS panels we can save some power by configuring the LCDC hardware block in one-shot mode. In this one-shot mode panel refresh is managed by software. This works well together with deferred io since it allows us to stop clocks for most of the time and only enable clocks when we actually want to trigger an update. When there is no fbdev activity the clocks are kept stopped which allows us to deep sleep. The refresh rate in deferred io mode is set using platform data. The same platform data can also be used to disable deferred io mode. As with other deferred io frame buffers user space code should use fsync() on the frame buffer device to trigger an update.

| * radeonfb: accelerate imageblit and other improvementsBenjamin Herrenschmidt2008-10-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement support for HW color expansion of 1bpp images, along with some improvements to the FIFO handling and other accel operations. The offset fixup code is now unnecessary as the fbcon core will call our set_par upon switch back from KD_GRAPHICS before anything else happens. I removed it as it would slow down accel operations. The fifo wait has been improved to avoid hitting the HW register as often, and the various accel ops are now performing better caching of register values. Overall, this improve accel performances. The imageblit acceleration does result in a small overall regression in performances on some machines (on the order of 5% on some x86), probably becaus the SW path provides a better bus utilisation, but I decided to ingnore that as the performances is still very good, and on the other hand, some machines such as some sparc64 get a 3 fold performance improvement.

* radeonfb: fix accel engine hangsDavid Miller2008-08-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some chips appear to have the 2D engine hang during screen redraw, typically in a sequence of copyarea operations. This appear to be solved by adding a flush of the engine destination pixel cache and waiting for the engine to be idle before issuing the accel operation. The performance impact seems to be fairly small. Here is a trace on an RV370 (PCI device ID 0x5b64), it records the RBBM_STATUS register, then the source x/y, destination x/y, and width/height used for the copy: ---------------------------------------- radeonfb_prim_copyarea: STATUS[00000140] src[210:70] dst[210:60] wh[a0:10] radeonfb_prim_copyarea: STATUS[00000140] src[2b8:70] dst[2b8:60] wh[88:10] radeonfb_prim_copyarea: STATUS[00000140] src[348:70] dst[348:60] wh[40:10] radeonfb_prim_copyarea: STATUS[80020140] src[390:70] dst[390:60] wh[88:10] radeonfb_prim_copyarea: STATUS[8002613f] src[40:80] dst[40:70] wh[28:10] radeonfb_prim_copyarea: STATUS[80026139] src[a8:80] dst[a8:70] wh[38:10] radeonfb_prim_copyarea: STATUS[80026133] src[e8:80] dst[e8:70] wh[80:10] radeonfb_prim_copyarea: STATUS[8002612d] src[170:80] dst[170:70] wh[30:10] radeonfb_prim_copyarea: STATUS[80026127] src[1a8:80] dst[1a8:70] wh[8:10] radeonfb_prim_copyarea: STATUS[80026121] src[1b8:80] dst[1b8:70] wh[88:10] radeonfb_prim_copyarea: STATUS[8002611b] src[248:80] dst[248:70] wh[68:10] ---------------------------------------- When things are going fine the copies complete before the next ROP is even issued, but all of a sudden the 2D unit becomes active (bit 17 in RBBM_STATUS) and the FIFO retry (bit 13) and FIFO pipeline busy (bit 14) are set as well. The FIFO begins to backup until it becomes full. What happens next is the radeon_fifo_wait() times out, and we access the chip illegally leading to a bus error which usually wedges the box. None of this makes it to the console screen, of course :-) radeon_fifo_wait() should be modified to reset the accelerator when this timeout happens instead of programming the chip anyways. ---------------------------------------- radeonfb: FIFO Timeout !

This will only happen if you 1) VC switch or 2) run "consolechars" or 3) unblank the screen. This seems to happen because until a redraw_screen() the screen scrolling method used by fbcon is not finalized yet. I've seen this with other fb drivers too. So if all you do is boot straight into X you will never see this bug on the relevant chips. Signed-off-by: David S.

* radeon: misc correctionsDavid Miller2008-08-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I have a new PCI-E radeon RV380 series card (PCI device ID 5b64) that hangs in my sparc64 boxes when the init scripts set the font. The problem goes away if I disable acceleration. I haven't figured out that bug yet, but along the way I found some corrections to make based upon some auditing. 1) The RB2D_DC_FLUSH_ALL value used by the kernel fb driver and the XORG video driver differ. I've made the kernel match what XORG is using. 2) In radeonfb_engine_reset() we have top-level code structure that roughly looks like: if (family is 300, 350, or V350) do this; else do that; ... if (family is NOT 300, OR family is NOT 350, OR family is NOT V350) do another thing; this last conditional makes no sense, is always true, and obviously was likely meant to be "family is NOT 300, 350, or V350". So I've made the code match the intent. Signed-off-by: David S.

* 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: backlight controlDavid Brownell2008-02-06
| | | | | | | | | | | | | | | | | | | | | | | | On the sam9 EK boards, the LCD backlight is hooked up to a PWM output from the LCD controller. It's controlled by "contrast" registers though. This patch lets boards declare that they have that kind of backlight control. The driver can then export this control, letting screenblank and other operations actually take effect ... reducing the typically substantial power drain from the backlight. Note that it's not fully cooked - doesn't force backlight off during system suspend - the "power" and "blank" events may not be done right This should be easily added in the future.

* Make asm-x86/bootparam.h includable from userspace.Rusty Russell2007-10-23
| | | | | | | | | | | To actually write a bootloader (or, say, the lguest launcher) currently requires duplication of these structures. Making them includable from userspace is much nicer. We merge the common userspace-required definitions of e820_32/64.h into e820.h for export. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
