This does not meet the requirement from servers as the sampling time of turbostat is usually very long on servers. So maintain a set of MSR buffer, and update them periodically before the 32bit MSR register is wrapped round, so as to avoid the overflow. The idea is similar to the implementation of ktime_get(): Periodical MSR timer: total_rapl_sum += (current_rapl_msr - last_rapl_msr); Using get_msr_sum() to get the accumulated RAPL: return (current_rapl_msr - last_rapl_msr) + total_rapl_sum; The accumulated RAPL mechanism will be turned on in next patch.

The problem is that the CX_ACPI% is eight characters long which does not work with tab formatting. One simple solution is to remove the underbar from the state name such that C1_ACPI will be displayed as C1ACPI.

I created the following patch which is intended to give a more user-friendly message. It's based on a patch for turbostat from Prarit Bhargava that was posted some time ago. The patch is "[v2] turbostat: Running on virtual machine is not supported" [1]. Given my limited knowledge of the topic, I can't say with confidence that this is the right solution, though (that's why this is not an official patch submission). Also, I'm not sure what the convention with exit codes is in this tool. Also, instead of the error message, perhaps the tool should just not print anything in this case, which is how it behaves in a "regular" VM?

This patch defines additional ethernet aliases in Espressobin DTS files, so bootloader can fill correct MAC address for DSA switch ports if more MAC addresses were specified. DT alias ethernet1 is used for wan port, DT aliases ethernet2 and ethernet3 are used for lan ports for both Espressobin revisions (V5 and V7).

However, what the code actually does is take the virtual address of the coherency_base symbol, and compare it with 0x0, which are never equal, and so the branch is never taken. In fact, with the MMU off, dereferencing the VA of coherency_base is not possible to begin with, nor can its value be relied upon with the MMU off since it is not cleaned to the Dcache as is done with coherency_phys_base in armada_370_coherency_init(). Instead, the value of coherency_phys_base is returned, which results in the correct behavior since it will be 0x0 as well if the coherency fabric is not mapped, and it is accessible with the MMU off. So just drop the comparison and the branch.

This is caused by the IP tunnel handlers with a higher priority in xfrm interface processing incoming packets by xfrm_input(), which would drop the packets and return 0 instead when anything wrong happens. Rather than changing xfrm_input(), this patch is to adjust the priority for the IP tunnel handlers in xfrm interface, so that the packets would go to xfrmi's later than the others', as the others' would not drop the packets when the handlers couldn't process them. Note that IPCOMP also defines its own IPIP tunnel handler and it calls xfrm_input() as well, so we must make its priority lower than xfrmi's, which means having xfrmi loaded would still break IPCOMP. We may seek another way to fix it in xfrm_input() in the future.

In such cases, we don't release the buffers and reuse them for consecutive transmits. However, currently we don't reset the Rx size which will be set as per the response for the last transmit. This may result in incorrect response size being interpretted as the firmware may repond with size greater than the one set but we read only upto the size set by previous response. Let us reset the receive buffer size to max possible in such cases as we don't know the exact size of the response.
