| * TILER: Cleaned up SiTA container manager algorithm codeLajos Molnar2012-08-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Removed unnecessary true/false identical macro values Changed tcm_area.type field to is2d Shortened variable names Renamed functions based on what they do Simplified some of the logic Removed most of the debug messages and unused/duplicate variables Removed duplicate parameter checks and made fuctions that always succeed void. Moved tcm_dbg.h macros into tcm_utils.h Tested using memmgr_1.0 tests. Signed-off-by: Lajos Molnar <molnar@ti.com> Signed-off-by: David Sin <davidsin@ti.com>
| * TILER: Added support for auto-packing of tiler blocks.Lajos Molnar2012-08-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Changed the way tiler blocks are maintained. 1D blocks are maintained similarly as before, but 2D blocks now reside on "reserved areas" that are maintained in area_info structs. Note, that even though auto-packing is supported, there is no open API to specify alignment other than kernel page size. Therefore, there is no expected allocation efficiency gain. Reference counts are also introduced although they are not yet used. Tested using memmgr_1.0 test as well as select allocation/freeing kernel calls to verify logic of maintaining blocks in the reserved area.

| * TILER: New APIs to optimize the freeing of used DMM pagesDavid Sin2012-08-17
| | | | | | | | | | | | | | | | | | | | | | | | | | We introduce two new dmm APIs --dmm_get_pages/dmm_free_pages -- to the tiler driver, which allocate and free a set of dmm pages. Previously, we allocated/freed single pages using dmm_get_page()/dmm_free_page. we observed that moving single pages from the used page stack to the free page stack caused excessive delays because of linear/unsorted searches.

| * OMAP: DSS2: DISPC: Fix minimum PCD valueTomi Valkeinen2012-08-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current driver had a hardcoded minimum value of 2 for pixel clock divisor (PCD). This doesn't seem to be right. OMAP4 TRM says that PCD can be 1 when not downscaling, and inverted pixel clock (IPC) is off. OMAP3 TRM says the same, but also in the register descriptions that PCD value 1 is invalid. OMAP2 TRM says PCD 2 is the minimum. OMAP2 is still untested, but for both OMAP3 and OMAP4 PCD of 1 seems to work fine. This patch adds a new DSS feature, FEAT_PARAM_DSS_PCD, which is used to find the minimum and maximum PCD. The minimum is set to 2 for OMAP2, and 1 for OMAP3/4. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
| * OMAP: DSS2: HDMI: change regn definitionTomi Valkeinen2012-08-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | regn divider is currently programmed to the registers without change, but when calculating clock frequencies it is used as regn+1. To make this similar to how DSI handles the dividers this patch changes the regn value to be used as such for calculations, but the value programmed to registers is regn-1. This simplifies the clock frequency calculations, makes it similar to DSI, and also allows us to use regn value 0 as undefined. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
| * OMAP: DSS2: HDMI: use default dividersTomi Valkeinen2012-08-17

| * drm/omap: add common scaled modesRicardo Salveti de Araujo2012-08-17
| | | | | | | | | | | | | | | | | | | | | | | | The idea behind it is just to add more modes, and add them with reduced blanking, so we have more choices while probing the EDID. It tries to identify what would be the native mode for the monitor, and add the scaler modes that would be compatible with it, but with reduced blanking. With that it can get more compatible modes with OMAP pixel clock. Signed-off-by: Ricardo Salveti de Araujo <ricardo.salveti@canonical.com>

| * Add omap drm display driverRob Clark2012-08-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A DSS based DRM display driver, which provides a plugin interface for 3d/2d accelerators to register. The core driver handles construction of CRTC/encoder/connectors to represent the hardware, and support KMS. This driver replaces omapfb. The omap drm driver allocates framebuffer memory and implements (with the help of drm_fb_helper) the legacy fbdev interface. The driver maps CRTCs to overlays, encoders to overlay-managers, and connectors to dssdev's.

| * gem: RFC: add support for private objectsAlan Cox2012-08-17
| | | | | | | | | | | | | | | | | | | | | | | | | | These small changes should allow GEM to be used with non shmem objects as well as shmem objects. In the GMA500 case it allows the base framebuffer to appear as a GEM object and thus acquire a handle and work with KMS. For i915 it ought to be trivial to get back the wasted memory but putting the system fb back into stolen RAM and in general I can imagine it allowing the use of GEM and thus KMS with all the older cards that have their framebuffer firmly placed in video RAM.

| * OMAP: DSS: HDMI: tame hdmi driverRob Clark2012-08-17
| | | | | | | | | | | | | | Main change is to avoid automatically picking timings. Now the driver defaults to a safe 640x480, and leaves it to the upper layer (drm driver) to pick the desired resolution based on what the user selects and the drm infrastucture's parsing of the EDID.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixs one performance bug on ARM Cortex A9 dual core platform, which has been reported on quite a few ARM machines(OMAP4, Tegra 2, snowball...), see details from link of https://bugs.launchpad.net/bugs/709245. In fact, one mb() on ARM is enough to flush L2 cache, but 'dummy->hw_token = token;' after mb() is added just for obeying correct mb() usage. The patch has been tested ok on OMAP4 panda A1 board, the performance of 'dd' over usb mass storage can be increased from 4~5MB/sec to 14~16MB/sec after applying this patch.
