Looking closer at this I have found that it had been broken almost 2 years ago with commit 2418996e3b100114edb2ae110d5d4acb928909d2, PM fixes for OMAP1. The definite reason for broken omapfb/lcdc behavoiur in PM mode appeared to be ARM_IDLECT1:IDLIF_ARM (bit 6) put into idle regardless of LCD DMA possibly running. The bit were set based on return value of the omap_dma_running() function that did not check for dedicated LCD DMA channel status. The patch below fixes this. Note that the hardcoded register value will be fixed during the next merge cycle to use OMAP_LCDC_ defines. Currently the OMAP_LCDC_ defines are local to drivers/video/omap/lcdc.c, so let's not start moving those right now.

This patch introduces a 'pwrdm_for_each_nolock()' helper which does the same, but without the spinlock locked. This fixes the following lockdep warning: [ 0.000000] WARNING: at kernel/lockdep.c:2460 lockdep_trace_alloc+0xac/0xec() [ 0.000000] Modules linked in: (unwind_backtrace+0x0/0xdc) from [<c0045464>] (warn_slowpath_common+0x48/0x60) (warn_slowpath_common+0x48/0x60) from [<c0067dd4>] (lockdep_trace_alloc+0xac/0xec) (lockdep_trace_alloc+0xac/0xec) from [<c009da14>] (kmem_cache_alloc+0x1c/0xd0) (kmem_cache_alloc+0x1c/0xd0) from [<c00b21d8>] (d_alloc+0x1c/0x1a4) (d_alloc+0x1c/0x1a4) from [<c00a887c>] (__lookup_hash+0xd8/0x118) (__lookup_hash+0xd8/0x118) from [<c00a9f20>] (lookup_one_len+0x84/0x94) (lookup_one_len+0x84/0x94) from [<c010d12c>] (debugfs_create_file+0x8c/0x20c) (debugfs_create_file+0x8c/0x20c) from [<c010d320>] (debugfs_create_dir+0x1c/0x20) (debugfs_create_dir+0x1c/0x20) from [<c000e8cc>] (pwrdms_setup+0x60/0x90) (pwrdms_setup+0x60/0x90) from [<c002e010>] (pwrdm_for_each+0x30/0x80) (pwrdm_for_each+0x30/0x80) from [<c000e79c>] (pm_dbg_init+0x7c/0x14c) (pm_dbg_init+0x7c/0x14c) from [<c00232b4>] (do_one_initcall+0x5c/0x1b8) (do_one_initcall+0x5c/0x1b8) from [<c00083f8>] (kernel_init+0x90/0x10c) (kernel_init+0x90/0x10c) from [<c00242c4>] (kernel_thread_exit+0x0/0x8) Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I was using Coccinelle with the mutex_unlock semantic patch, and it unconvered this problem. It appears to be a valid missing unlock issue. This change should correct it by moving the unlock below the label. This patch is against the mainline kernel.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | the original flush operation is to flush the function address which is copied from. But we do not change the function code and it is not necessary to flush it.
