2015-06-12MGS-532 [#1630] P13 driver meet "AXI BUS ERROR" on GC2000rel_imx_3.10.17_1.0.3_patchShawn Xiao
When run Antutu benchmark several times continuously, it will show "AXI BUS ERROR". The root cause is When unlock a surface, driver must flush its GPU cache. Otherwise, GPU may write out the cache after GPU address is freed, which will cause MMU Exception or AXI bus error. Even if GPU address isn't freed, data in cache may pollute memory after memory is used by another surface. The solution is Before an event is written to command buffer, driver checks the group of records linked to this event to find out which kinds of cache need to flush. This method doesn't care whether the record is from user side or kernel. And driver generates only one flush for a group of records.

2015-05-15MGS-327 [#ccc] Unexpected exit like Ctrl-C cause Kernel crashShawn Xiao
Issue in MGS-327 happens when Apps exit unexpectedly such as receiving Ctrl-C terminated signal. This is caused by some operations like memory free are done twice. If the exit happens when ioctl back from kernel space, the event queue will have no chance to be freed but the events in the queue have been put to GPU. To prevent memory leak, when Apps exit GPU driver will clean the resource it occupied. So when flush the command buffer, the original event queue will be put to kernel again. This will lead the events in the queue will be redo. To avoid this problem, after the AddList operation in Kernel, clean the iface and copy it to user space. Once the same iface is transfered to kernel again, its key information will be null and it will not pass Addlist parameter check. So it will not be done twice.

mx6dl-sabresd move pmic device node from imx6qdl-sabresd.dtsi to up-level, and add another layer on imx6dl-sabresd to diff pfuze100 or pfuze200. Meanwhile only work in ldo-enable mode if using pfuze200,since 'SW1C' switch regulator is cut for cost-down which means VDDARM_IN and VDDSOC_IN have to share the same switch regulator Signed-off-by: Robin Gong <b38343@freescale.com> (cherry picked from commit 32e4e161b087bfdcea74bd80f0b24c341092c96b)
2014-05-26pfuze100-regulator: Fix of_node_get() parameterFabio Estevam
Since commit d7857c42 (regulator: pfuze100: Use of_get_child_by_name) we get the following probe failure: pfuze100-regulator 1-0008: Full layer: 1, Metal layer: 0 pfuze100-regulator 1-0008: FAB: 0, FIN: 0 pfuze100-regulator 1-0008: regulators node not found pfuze100-regulator: probe of 1-0008 failed with error -22 Now that of_get_child_by_name() is used we should adjust the device_node pointer 'np' to not get the parent node anymore.

2014-04-03ENGR00306875-2 video: mxc_hdmi: Set hdmi cable state a bit earilierNicolin Chen
During hdmi hotplug test, there's a possibility that X-server unblanks the frame buffer while HDMI-audio just gets the signal to start playback. Then audio would get an unblanked state right before the playback and bypassed the DMA enabling code. So this issue is caused by the race between unblank and set_cable_state(). This patch sets the hdmi cable state a bit earilier so as to let audio play first. If unblank happens later, the hdmi core and hdmi audio would be robust enough to handle that case as long as it's not racing with the other parts.

pointer" After change the pointer, ALSA lib would re-copy the initial data to DMA buffer because the pointer is pointing the zero position at the beginning, which results an audiable duplicated playback at the first eight periods. Even though dropping this patch would cause pointer being incorrectly estimated. But to maintain the sanity of basic playback, we revert the previous patch.
