Problem booting using latest linaro-linux-tracking (3.16.0-rc5)/mainline kernel (3.16.0-rc4) on Samsung Arndale Baord

by Mohammad Merajul Islam Molla

Hello, I am having problem booting from latest linaro-linux-tracking (3.16.0-rc5) on Samsung Arndale Board (with two cpus). The same thing happens with mainline kernel (3.16.0-rc4). Here is what happens - 1. During build I got the error message - LD sound/built-in.o MK_FW firmware/edid-1920x1080.fw.gen.S make[1]: *** No rule to make target `firmware/edid-1920x1080.fw', needed by `firmware/edid-1920x1080.fw.gen.o'. Stop. make: *** [firmware] Error 2 I set CONFIG_EXTRA_FIRMWARE="" and could proceed with build. 2. At the end of build I got the below error message - Kernel: arch/arm/boot/zImage is ready multiple (or no) load addresses: This is incompatible with uImages Specify LOADADDR on the commandline to build an uImage make[1]: *** [arch/arm/boot/uImage] Error 1 make: *** [uImage] Error 2 I passed loadaddr as parameter - make uImage LOADADDR=0x40008000 (this address I got from build output of linux-linaro-tracking 3.14.0). With this build was successful and uImage generated. 3. After that I got the following log during boot - [ 1.125626] Trying to unpack rootfs image as initramfs...

Is there something I am doing wrong or is it problem with recent kernel? -- Thanks, -Meraj

[PATCH V2] cpufreq: move policy kobj to policy->cpu at resume

by Viresh Kumar

This is only relevant to implementations with multiple clusters, where clusters have separate clock lines but all CPUs within a cluster share it. Consider a dual cluster platform with 2 cores per cluster. During suspend we start offlining CPUs from 1 to 3. When CPU2 is remove, policy->kobj would be moved to CPU3 and when CPU3 goes down we wouldn't free policy or its kobj. Now on resume, we will get CPU2 before CPU3 and will call __cpufreq_add_dev(). We will recover the old policy and update policy->cpu from 3 to 2 from update_policy_cpu(). But the kobj is still tied to CPU3 and wasn't moved to CPU2. We wouldn't create a link for CPU2, but would try that while bringing CPU3 online. Which will report errors as CPU3 already has kobj assigned to it. This bug got introduced with commit 42f921a, which overlooked this scenario. To fix this, lets move kobj to the new policy->cpu while bringing first CPU of a cluster back. We already have update_policy_cpu() routine which can be updated with this change. That would get rid of the cpufreq_nominate_new_policy_cpu() as update_policy_cpu() is also called on CPU removal. To achieve that we add another parameter to update_policy_cpu() as cpu_dev is present with both the callers. Fixes: ("42f921a cpufreq: remove sysfs files for CPUs which failed to come back after resume") Cc: Stable <stable(a)vger.kernel.org> # 3.13+ Reported-by: Bu Yitian <ybu(a)qti.qualcomm.com> Reported-by: Saravana Kannan <skannan(a)codeaurora.org> Signed-off-by: Viresh Kumar <viresh.kumar(a)linaro.org> --- V1->V2: Move kobject_move() call to update_policy_cpu(), which makes cpufreq_nominate_new_policy_cpu() almost empty.

[PATCH] tty: kgdb_nmi: Convert kgdb_nmi_tty_enabled into a module parameter

by Daniel Thompson

At present it is not possible to boot with the ttyNMI0 console treating character input normally. To use the console requires that kdb be entered and the nmi_console command be used to enable the console (or if only kgdb is present then gdb must directly manipulate the value of kgdb_nmi_tty_enabled). Introducing a module parameter makes the console much more usable.

[PATCH] arm: ks8695: Migrate debug_ll macros to shared directory

by Daniel Thompson

As part of the migration a couple of uart definitions have been copied from of the platform specific header files. Note that, in order to keep oldconfig working nicely we must defer the removal of arch/arm/mach-ks8695/include/mach/debug-macro.S until DEBUG_LL_UART_NONE has been removed.
