2011-12-02OMAPDSS: APPLY: cleanup dss_mgr_start_updateTomi Valkeinen
dss_mgr_start_update() has a loop, of which sole purpose is to find the manager used for this update. The whole loop is extra, as we already know the manager. Remove the loop. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2011-12-02OMAPDSS: APPLY: skip isr register and config for disabled displaysTomi Valkeinen
There's no need to register the vsync ISR and configure the hardware if the overlay manager is disabled, so this patch adds a check for disabled managers to the omap_dss_mgr_apply() function. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2011-12-02OMAPDSS: APPLY: skip isr register and config for manual update displaysTomi Valkeinen
The mechanism to cache manager and overlay settings and configure them into the HW registers in VSYNC is meant only for auto-update displays, as it doesn't make sense (and doesn't work) for manual-update displays. This patchs adds a check so that we skip the above for manual update displays. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2011-12-02OMAPDSS: APPLY: track whether a manager is enabledTomi Valkeinen
Add "enabled" field to struct omap_overlay_manager, which tells if the output is enabled or not. This will be used in apply.c in the following patches. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2011-12-02OMAPDSS: hide manager's enable/disable()Tomi Valkeinen
omap_overlay_manager struct contains enable() and disable() functions. However, these are only meant to be used from inside omapdss, and thus it's bad to expose the functions. This patch adds dss_mgr_enable() and dss_mgr_disable() functions to apply.c, which handle enabling and disabling the output. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2011-12-02OMAPDSS: create apply.cTomi Valkeinen
Create a new file, apply.c, and move code about handling the apply-mechanism and configuration of the managers and overlays from manager.c to apply.c. Not all related code is moved in this patch, but only the core apply/configure functions. The later patches move rest of the code from overlay.c and manager.c, adding necessary locking at the same time. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2011-12-02OMAPDSS: apply affects only one overlay managerTomi Valkeinen
omap_dss_mgr_apply currently applies settings to all overlays and overlay managers. The reason for this was to support cases where configuration changes affecting multiple managers are made. However, the current code doesn't support changing such configurations, so the functionality is not needed. Change the apply to affect only the manager given as an argument, and the overlays attached to that manager. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2011-12-02OMAPDSS: split omap_dss_mgr_apply() to smaller funcsTomi Valkeinen
Split omap_dss_mgr_apply() into smaller functions for clarity. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2011-12-02OMAPDSS: add ovl/mgr_manual_update() helpersTomi Valkeinen
Add helper functions ovl_manual_update() and mgr_manual_update() which return whether the overlay or manager is used with a manual update display. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2011-12-02OMAPDSS: remove unneeded dss_ovl_wait_for_go()Tomi Valkeinen
There's an unnecessary wrapper function, dss_ovl_wait_for_go(), which does nothing else than call dss_mgr_wait_for_go_ovl(). The dss_ovl_wait_for_go() function can be removed. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2011-12-02OMAPDSS: DISPC: remove unused functionsTomi Valkeinen
Remove unused functions: dispc_mgr_get_default_color dispc_mgr_get_trans_key dispc_mgr_trans_key_enabled dispc_mgr_alpha_fixed_zorder_enabled Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2011-12-02OMAPDSS: setup manager with dispc_mgr_setup()Tomi Valkeinen
Change manager configuration to be similar to overlay configuration by creating dispc_mgr_setup() which takes omap_overlay_manager_info as parameter. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2011-12-02OMAPDSS: separate overlay channel from ovl_setupTomi Valkeinen
Overlay channel is configured with ovl_setup, with all the other overlay attriutes. This patch separates overlay channel setup so that we can later configure the channel only when needed. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2011-12-02OMAPDSS: separate FIFO threshold setup from ovl_setupTomi Valkeinen
Overlay FIFO thresholds are configured with ovl_setup, with all the other overlay attributes. This patch separates FIFO threshold setup so that we can later configure FIFO thresholds only when needed. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2011-12-02OMAPDSS: handle ilace/replication when configuring overlayTomi Valkeinen
Move the configuration of interlace and replication from omap_dss_mgr_apply() to configure_overlay(). This removes the need to store the values into the cache data. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2011-12-02OMAPDSS: DISPC: handle 0 out_width/out_height in ovl_setup()Tomi Valkeinen
Overlay out_width/height are set to 0 when scaling is not used by the users of omapdss. Currently ovl_setup() expects the caller of ovl_setup() to convert those zero values to width or height. This patch makes ovl_setup() accept zero values for out_width/height, making calling ovl_setup() a bit simpler as the overlay_info can be just passed to this function without modifications. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2011-12-02OMAPDSS: pass ovl manager to dss_start_updateTomi Valkeinen
dss_start_update() takes currently the dss device as a parameter. Change the parameter to ovl manager, as that is what the dss_start_update() actually needs. Change the name of the function to dss_mgr_start_update() to reflect the change. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2011-12-02OMAPDSS: remove partial update from panel-taalTomi Valkeinen
Partial update for manual update displays has never worked quite well: * The HW has limitations on the update area, and the x and width need to be even. * Showing a part of a scaled overlay causes artifacts. * Makes the management of dispc very complex Considering the above points and the fact that partial update is not used anywhere, this and the following patches remove the partial update support. This will greatly simplify the following re-write of the apply mechanism to get proper locking and additional features like fifo-merge. This patch removes the partial update from the panel-taal.c.

2011-12-02OMAPDSS: Remove old fifomerge hacksTomi Valkeinen
Once in a time omapdss had basic support for fifomerge. Fifomerge was removed as the implementation didn't work properly, and a proper implementation is a complex problem. However, some unused fifo-merge related code was left behind. This patch removes those. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

2011-12-02OMAPDSS: DSI: disable DDR_CLK_ALWAYS_ON when entering ULPSTomi Valkeinen
ULPS cannot be entered if the DDR clk is enabled. Thus disable the DDR clk before entering ULPS. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2011-12-02OMAPDSS: DSI: improve wait_for_bit_changeTomi Valkeinen
We sometimes get timeout when disabling the DSI interface with video mode. It looks like the disable will stall until the current frame has been finished, and this can take multiple milliseconds. wait_for_bit_change() currently uses a busyloop to wait for a bit to change. This is used in multiple places. The problem is, we don't have clear understanding how long particular operations can take, so the function needs to support longer waits. Improve wait_for_bit_change() to first busy loop for 100 times to see if the bit changes almost right away. If the bit hasn't changed, move to a loop with a sleep of 1ms, and poll for 500ms. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2011-12-02OMAPDSS: DSI: fix lane handling when entering ULPSTomi Valkeinen
The current code always enters ULPS for 3 lanes. This is not right, as there could be only 2 lanes used, and on OMAP4 we have 5 lanes. Fix the code to put all used lanes into ULPS. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2011-12-02OMAPDSS: DSI: remove dsi_get_num_lanes_usedTomi Valkeinen
There's no longer need for the dsi_get_num_lanes_used function, so it can be removed. The lane check in dsi_init_display() can be removed as the validity of the config will be verified when parsing it. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2011-12-02OMAPDSS: DSI: use lane config in dsi_cio_enable_lane_overrideTomi Valkeinen

2011-12-02OMAPDSS: DSI: count with number of lanesTomi Valkeinen
DSI driver currently counts used lanes and number of supported lanes by using the number of data lanes (i.e. excluding clock lane). This patch changes this to use the number of all lanes so that the following lane config patches are cleaner. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2011-12-02OMAPDSS: DISPC: Flush posted writes when enabling outputsTomi Valkeinen
Flush posted write in _enable_lcd_out() and _enable_digit_out(). This ensures the the lcd/digit bit is written before the code starts waiting for interrupts about enabling/disabling the output. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2011-12-02OMAPDSS: DSI: flush posted write in send_btaTomi Valkeinen
Flush posted write after setting the bit to send the BTA to ensure the BTA is sent right away, as the code in dsi_vc_send_bta_sync() waits for an interrupt caused indirectly by sending the BTA. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

2011-12-01ocfs2: avoid unaligned access to dqc_bitmapAkinobu Mita
The dqc_bitmap field of struct ocfs2_local_disk_chunk is 32-bit aligned, but not 64-bit aligned. The dqc_bitmap is accessed by ocfs2_set_bit(), ocfs2_clear_bit(), ocfs2_test_bit(), or ocfs2_find_next_zero_bit(). These are wrapper macros for ext2_*_bit() which need to take an unsigned long aligned address (though some architectures are able to handle unaligned address correctly) So some 64bit architectures may not be able to access the dqc_bitmap correctly. This avoids such unaligned access by using another wrapper functions for ext2_*_bit(). The code is taken from fs/ext4/mballoc.c which also need to handle unaligned bitmap access.

2011-12-01Btrfs: fix meta data raid-repair merge problemJan Schmidt
Commit 4a54c8c16 introduced raid-repair, killing the individual readpage_io_failed_hook entries from inode.c and disk-io.c. Commit 4bb31e92 introduced new readahead code, adding a readpage_io_failed_hook to disk-io.c. The raid-repair commit had logic to disable raid-repair, if readpage_io_failed_hook is set. Thus, the readahead commit effectively disabled raid-repair for meta data. This commit changes the logic to always attempt raid-repair when needed and call the readpage_io_failed_hook in case raid-repair fails. This is much more straight forward and should have been like that from the beginning.
