2014-09-26video: tegra: nvmap: fix use-after-free race conditionManeet Singh
Incremented nvmap_handle ref count in utility function nvmap_get_id_from_dmabuf_fd() before the function release reference to dma buffer. This is required to avoid race conditions in nvmap code where nvmap_handle returned by this function could be freed concurrently while the caller is still using it. As a side effect of above change, every caller of this utility function must decrement nvmap_handle ref count after using the returned nvmap_handle.

2014-08-26cpufreq: ondemand: Change the calculation of target frequencyStratos Karafotis
The ondemand governor calculates load in terms of frequency and increases it only if load_freq is greater than up_threshold multiplied by the current or average frequency. This appears to produce oscillations of frequency between min and max because, for example, a relatively small load can easily saturate minimum frequency and lead the CPU to the max. Then, it will decrease back to the min due to small load_freq. Change the calculation method of load and target frequency on the basis of the following two observations: - Load computation should not depend on the current or average measured frequency. For example, absolute load of 80% at 100MHz is not necessarily equivalent to 8% at 1000MHz in the next sampling interval. - It should be possible to increase the target frequency to any value present in the frequency table proportional to the absolute load, rather than to the max only, so that: Target frequency = C * load where we take C = policy->cpuinfo.max_freq / 100. Tested on Intel i7-3770 CPU @ 3.40GHz and on Quad core 1500MHz Krait. Phoronix benchmark of Linux Kernel Compilation 3.1 test shows an increase ~1.5% in performance. cpufreq_stats (time_in_state) shows that middle frequencies are used more, with this patch. Highest and lowest frequencies were used less by ~9%. [rjw: We have run multiple other tests on kernels with this change applied and in the vast majority of cases it turns out that the resulting performance improvement also leads to reduced consumption of energy. The change is additionally justified by the overall simplification of the code in question.] Bug 1359622 Change-Id: Ibcbee5afef154c47e3ae45e133f3a0435d2a4fec Signed-off-by: Stratos Karafotis <stratosk@semaphore.gr> Acked-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Rafael J.

Since the user space code may works in either 32 or 64 bit mode, attentions should be taken while passing pointers from user space to the kernel. In this case, the p_value of struct nvc_param and power_on/power_off of struct virtual_device received from the user space should be handled properly. The solution is to create a set of 32 bit version of structures nvc_param and virtual_device along with some dedicated 32 bit mode ioctl commands, then in the ioctl functions, the 32 bit user mode access will be handled separately. bug 1518359 Change-Id: I4cbbeeaef446ab962aaa1f92251ce1fd9d5723aa Signed-off-by: Charlie Huang <chahuang@nvidia.com> Reviewed-on: http://git-master/r/437390 (cherry picked from commit 3fdbc210fc9f33d0f89af079a89bdb1f41e73ecb) Reviewed-on: http://git-master/r/482230 Reviewed-by: Automatic_Commit_Validation_User GVS: Gerrit_Virtual_Submit Reviewed-by: Thomas Cherry <tcherry@nvidia.com>
