[alsa-devel] [PATCH 2/4] ARM: dove: prepare new Dove DT Kconfig variable
by Sebastian Hesselbarth 04 Mar '14

04 Mar '14

DT-enabled Dove will move over from ARCH_DOVE in mach-dove to MACH_DOVE in mach-mvebu. As non-DT ARCH_DOVE will stay to rot for a while, add a new DT-only MACH_DOVE to mmc, thermal, wdt, and asoc Kconfigs.

[alsa-devel] [PATCH] ASoC: da732x: Replace hw_read usage with snd_soc_read()
by Mark Brown 04 Mar '14

04 Mar '14

From: Mark Brown <broonie(a)linaro.org> Pre-merge code was using direct hw_read() calls as an out of framework way of doing volatile register I/O when not using regmap. This has never functioned correctly in mainline due to the regmap conversion, the hw_read() implementation still does caching. In order to facilitate removal of the subsystem level I/O code convert to use snd_soc_read(), there should be no functional impact.

[alsa-devel] [PATCH] ASoC: cache: Do the codec->reg_cache zero pionter check
by Xiubo Li 04 Mar '14

04 Mar '14

For the snd_soc_cache_init(), the reg_size maybe zero and then the value of codec->reg_cache, which is alloced via kzalloc, maybe equal to ZERO_SIZE_PTR. If the reg parameter of snd_soc_cache_write() is large enough, the cache[idx] = val maybe cause the kernel crash... So this patch fix this via doing the zero pionter check of it.

Since 3.14-rc1 only DT boot has been supported on N810, so this file fails to init. Make a minimal fix to retain functionality. This file should be properly converted to DT in longer term. There seems to be still other unresolved issues with N810 audio support, but this patch is needed at minimum as otherwise the machine driver probing would completely fail.

[alsa-devel] change kmalloc into vmalloc for large memory allocations
by Wang, Yalin 04 Mar '14

04 Mar '14

Hi I find there is some drivers use kmalloc to allocate large Memorys during module_init, some can be changed to use vmalloc To save some low mem, I add log in kernel to track , And list them here: https://git.kernel.org/cgit/linux/kernel/git/will/linux.git/tree/drivers/us… https://git.kernel.org/cgit/linux/kernel/git/will/linux.git/tree/sound/soc/… https://git.kernel.org/cgit/linux/kernel/git/will/linux.git/tree/net/netfil… https://git.kernel.org/cgit/linux/kernel/git/will/linux.git/tree/net/netfil… https://git.kernel.org/cgit/linux/kernel/git/will/linux.git/tree/net/netfil… https://git.kernel.org/cgit/linux/kernel/git/will/linux.git/tree/net/netfil… https://git.kernel.org/cgit/linux/kernel/git/will/linux.git/tree/drivers/in… they allocate large memory from 10k~64K , this will use lots of low mem, instead if we use vmalloc for these drivers , it will be good for some devices like smart phone, we often encounter some errors like kmalloc failed because there is not enough low mem , especially when the device has physical memory less than 1GB . could this module change the memory allocation into vmalloc ? I was thinking that if we can introduce a helper function in kmalloc.h like this : Kmalloc(size, flags) { If (size > PAGE_SIZE && flags&CAN_USE_VMALLOC_FLAG) return vmalloc(size); Else return real_kmalloc(size); } Kfree(ptr) { If (is_vmalloc_addr(ptr)) Vfree(ptr); Else Kfree(ptr); } But we need add some flags to ensure always use kmalloc for Some special use (dma etc..) How do you think of it ? Thanks
