| | * [ARM] pxafb: avoid the racing condition in pxafb_smart_threadEric Miao2008-12-171-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | fbi->state change shall really be protected by fbi->ctrlr_lock, where the change is sheltered. There is a possibility that pxafb_smart_thread will start update the LCD panel when fbi->state == C_ENABLE, while all other initialization isn't done. Signed-off-by: Eric Miao <eric.miao@marvell.com>
| | * [ARM] pxafb: allow insertion of delay to the smart panel command sequenceEric Miao2008-12-171-3/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some smart panel requires a delay between command sequences, while PXA LCD controller didn't provide such one, let's emulate this by software. A software delay marker can be inserted into the command sequence, once pxafb_smart_queue() detects this, it flushes the previous commands and delay for a specified number of milliseconds.

| | * [ARM] pxafb: allow better platform configurable smart panel timingEric Miao2008-12-171-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For smart panels (LCD panel with internal framebuffer), the following LCCR3 register bits have different meanings than the parallel one: LCCR3_PCP - controls the L_PCLK_WR polarity LCCR3_HSP - controls the L_LCLK_A0 polarity LCCR3_VSP - controls the L_FCLK_RD polarity To keep minimum change to the original parallel timing, the .lcd_conn flags and 'pxafb_mode_info.sync' are re-used to reflect this: LCD_PCLK_EDGE_{RISE,FALL} - configures LCCR3_PCP sync & FB_SYNC_{HOR,VERT}_HIGH_ACT - configures LCCR3_{HSP,VSP} Signed-off-by: Eric Miao <eric.miao@marvell.com>

This is a fairly big chunk of work that allows DRM drivers to provide full output control and configuration capabilities to userspace. It was motivated by several factors: - the fb layer's APIs aren't suited for anything but simple configurations - coordination between the fb layer, DRM layer, and various userspace drivers is poor to non-existent (radeonfb excepted) - user level mode setting drivers makes displaying panic & oops messages more difficult - suspend/resume of graphics state is possible in many more configurations with kernel level support This commit just adds the core DRM part of the mode setting APIs. Driver specific commits using these new structure and APIs will follow.

We also manipulate _PAGE_NO_CACHE and _PAGE_GUARDED by hand in all sorts of places. This changes the logic so that instead, the PTE now contains _PAGE_COHERENT for all normal RAM pages thay have I = 0 on platforms that need it. The hash code clears it if the feature bit is not set. It also adds some clean accessors to setup various valid combinations of access flags and change various bits of code to use them instead. This should help having the PTE actually containing the bit combinations that we really want. I also removed _PAGE_GUARDED from _PAGE_BASE on 44x and instead set it explicitely from the TLB miss. I will ultimately remove it completely as it appears that it might not be needed after all but in the meantime, having it in the TLB miss makes things a lot easier.

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.

The sh_mobile_lcdcfb hardware does not support scatter gather so we need physically contiguous memory to back our frame buffer.

Fix that. This is needed for sh_mobile_lcdcfb since we always enable deferred io at compile time but we may disable deferred io for some types of hardware configurations.
