| | * OMAPDSS: HDMI: PHY burnout fixTomi Valkeinen2012-01-263-4/+71
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A hardware bug in the OMAP4 HDMI PHY causes physical damage to the board if the HDMI PHY is kept powered on when the cable is not connected. This patch solves the problem by adding hot-plug-detection into the HDMI IP driver. This is not a real HPD support in the sense that nobody else than the IP driver gets to know about the HPD events, but is only meant to fix the HW bug. The strategy is simple: If the display device is turned off by the user, the PHY power is set to OFF. When the display device is turned on by the user, the PHY power is set either to LDOON or TXON, depending on whether the HDMI cable is connected. The reason to avoid PHY OFF when the display device is on, but the cable is disconnected, is that when the PHY is turned OFF, the HDMI IP is not "ticking" and thus the DISPC does not receive pixel clock from the HDMI IP. This would, for example, prevent any VSYNCs from happening, and would thus affect the users of omapdss. By using LDOON when the cable is disconnected we'll avoid the HW bug, but keep the HDMI working as usual from the user's point of view. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
| | * OMAPDSS: use sync versions of pm_runtime_putTomi Valkeinen2012-01-266-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | omapdss doesn't work properly on system suspend. The problem seems to be the fact that omapdss uses pm_runtime_put() functions when turning off the hardware, and when system suspend is in process only sync versions are allowed. Using non-sync versions normally and sync versions when suspending would need rather ugly hacks to convey the information of suspending/not-suspending to different functions. Optimally the driver wouldn't even need to care about this, and the PM layer would handle syncing when suspend is in process. This patch changes all omapdss's pm_runtime_put calls to pm_runtime_put_sync. This fixes the suspend problem, and probably the performance penalty of always using sync versions is negligible.

It can arbitrarily map between pixel formats and internal representation and also between internal representation and the physical connection to the display. The driver used to change the mapping between internal representation and display connection depending on the user selected bpp which is wrong. Instead, the mapping is specified by the hardware, so an additional field in platform data is added to describe the connection between i.MX and the display. The default for this field is RGB666 which seems to be the only configuration which works without this patch, so I assumed that all in Kernel boards are connected this way. This patch has been tested on a RGB666 connected display and a RGB888 connected display in both 16bpp and 32bpp modes.

In OMAP2 and OMAP3 the required clock rate is a function of pixel clock, vertical downscale ratio and horizontal downscale ratio whereas in OMAP4 it is a function of pixel clock and horizontal downscale ratio only. Selection of 3-tap vs 5-tap coefficients depends on clock rate line buffer width in OMAP3 whereas in OMAP4 it is independent of clock rate and line buffer width. In OMAP2 3-tap for vertical and 5-tap for horizontal scaling is used. In OMAP4 5-tap is used both for horizontal and vertical scaling for better performance. Also, the number and width of line buffers differs in OMAP3 and OMAP4. So, clock functions have been fined tuned for OMAP3 and support has been added added for OMAP4. This code has been tested on OMAP2, OMAP3 and OMAP4, and scaling issues due to clock errors have been resolved.

M is the inverse of low pass cut off frequency of the sampling filter. For vertical scaling 3 tap or 5 tap tables are used based on the clock rate and width of the line buffer whereas in OMAP2 3 tap is always used. For horizontal scaling however 5 tap tables are always used. New coefficients and the corresponding logic have been tested on OMAP2, OMAP3 and OMAP4. Horizontal and vertical scaling worked fine except for some 3 tap vs 5 tap issue during vertical upscaling and clock failing issues which is acknowledged in the next patch. Vertical upscaling was found to perform better under 5 taps. The 24 coefficient tables have been moved to another file dispc_coefs.c for proper maintainance. This code is written based on code written by Lajos Molnar <lajos@ti.com> in Android Kernel for scaling. Lajos Molnar <lajos@ti.com> had fine tuned the FIR coefficient selection process and reduced outliness and blockiness around images when upscaling more than 2 times.

| | * | | | OMAPDSS: fix potential NULL pointer ref in OCP_ERR handling pathRob Clark2012-01-021-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The dispc's error handler tries to disable all outputs when OCP_ERR happens. However, the code doesn't check if there actually is a display on each particular output, nor if there's a driver for the display. This may lead to NULL pointer reference.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current code will always write fifo threshold values to the register, even if they are the same as previously.

However, when a fifo size configuration is added, we need to always configure the thresholds for all overlays. This patch prepares for that by changing the fifo threshold configuration to always handle all overlays. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

Current code handled this in a hacky way, setting op->enabled to true temporarily when calling functions that need to consider the state when the overlay is enabled. This patch makes this a bit cleaner, adding "enabling" field, which is set when the overlay is not yet enabled but should be considered in the checks and calculations.

This is a bit misleading, as one does not presume "write registers" function to also set the GO bit. Thus this patch splits the setting of GO bits into a separate function, dss_set_go_bits, which is used after writing the registers. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
| | * | | | OMAPDSS: APPLY: clear shadow dirty flags only if GO had been setTomi Valkeinen2011-12-021-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the apply irq handler the code currently clears the shadow dirty flags whenever the manager in question is not busy (i.e. GO bit is down). However, this is not quite right, as the GO bit may have never been set. While not done in the current code, the above would cause bug in scenario where the registers are written, and thus shadow_dirty flag is set, but the GO bit will be set only later. In this case the shadow_dirty flags would be cleared, even if the HW is not using the new configurations. This patch fixes the issue by clearing the shadow flags only when the GO bit is clear, and the GO bit had been set. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

However, need_isr() is missing some cases where we need the irq handler. This patch adds checks for shadow dirty flags, so that the irq handler is started/kept running while shadow dirty flags are set. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

This doesn't work, as the enable status of an overlay is in the extra_info group, and thus extra_info_update_ongoing() reports false when we are disabling an overlay. This causes wait_pending_extra_info_updates() to not wait for the ongoing overlay disable. This patch changes extra_info_update_ongoing() to check the state of overlays marked as disabled.

Only attributes that can be checked independently, without knowing the display being used, is done here (thus "simple"). We can use this function in dss_mgr_set_info().
