e9c65942 - examples: detect default build directory

Wed, 27 Mar 2019 13:58:05 +0000

examples: detect default build directoryMost examples have in their makefiles a default RTE_TARGET directory to beused in case RTE_TARGET is not set. Rather than just using a hard-codeddefault, we can instead detect what the build directory is relative toRTE_SDK directory.This fixes a potential issue for anyone who continues to build using"make install T=x86_64-native-linuxapp-gcc" and skips setting RTE_TARGETexplicitly, instead relying on the fact that they were building in adirectory which corresponded to the example default path - which waschanged to "x86_64-native-linux-gcc" by commit 218c4e68c1d9 ("mk: uselinux and freebsd in config names").Signed-off-by: Bruce Richardson Acked-by: Ferruh Yigit List of files: /dpdk/examples/vm_power_manager/Makefile

218c4e68 - mk: use linux and freebsd in config names

Wed, 06 Mar 2019 16:22:42 +0000

mk: use linux and freebsd in config namesRather than using linuxapp and bsdapp everywhere, we can change things touse the, more readable, terms "linux" and "freebsd" in our build configs.Rather than renaming the configs we can just duplicate the existing oneswith the new names using symlinks, and use the new names exclusivelyinternally. ["make showconfigs" also only shows the new names to keep thelist short] The result is that backward compatibility is kept fully but anynew builds or development can be done using the newer names, i.e. both"make config T=x86_64-native-linuxapp-gcc" and "T=x86_64-native-linux-gcc"work.Signed-off-by: Bruce Richardson List of files: /dpdk/examples/vm_power_manager/Makefile

a63504a9 - examples/power: add JSON string handling

Wed, 17 Oct 2018 13:05:31 +0000

examples/power: add JSON string handlingAdd JSON string handling to vm_power_manager for JSON strings receivedthrough the fifo. The format of the JSON strings are detailed in thenext patch, the vm_power_manager user guide documentation updates.This patch introduces a new dependency on Jansson, a C library forencoding, decoding and manipulating JSON data. To compile the sample appyou now need to have installed libjansson4 and libjansson-dev (these maybe named slightly differently depending on your Operating System)Signed-off-by: David Hunt Acked-by: Anatoly Burakov List of files: /dpdk/examples/vm_power_manager/Makefile

4b1a631b - examples/vm_power: add oob monitoring functions

Fri, 13 Jul 2018 14:22:56 +0000

examples/vm_power: add oob monitoring functionsThis patch introduces the out-of-band (oob) core monitoringfunctions.The functions are similar to the channel manager functions.There are function to add and remove cores from thelist of cores being monitored. There is a function to initialisethe monitor setup, run the monitor thread, and exit the monitor.The monitor thread runs in it's own lcore, and is separatefunctionality to the channel monitor which is epoll based.THis thread is timer based. It loops through all monitored cores,calculates the branch ratio, scales up or down the core, thensleeps for an interval (~250 uS).The method it uses to read the branch counters is a pread on the/dev/cpu/x/msr file, so the 'msr' kernel module needs to be loaded.Also, since the msr.h file has been made unavailable in recentkernels, we have #defines for the relevant MSRs included in thecode.The makefile has a switch for x86 and non-x86 platforms,and compiles stub function for non-x86 platforms.Signed-off-by: David Hunt Acked-by: Radu Nicolau List of files: /dpdk/examples/vm_power_manager/Makefile

99a968fa - examples/vm_power: add core list parameter

Fri, 13 Jul 2018 14:22:55 +0000

examples/vm_power: add core list parameterAdd in the '-l' command line parameter (also --core-list)So the user can now pass --corelist=4,6,8-10 and it willexpand out to 4,6,8,9,10 using the parse function providedin parse.c (parse_set).This list of cores is then used to enable out-of-band monitoringto scale up and down these cores based on the ratio of branchhits versus branch misses. The ratio will be low when a pollloop is spinning with no packets being received, so the frequencywill be scaled down.Also , as part of this change, we introduce a core_info structwhich keeps information on each core in the system, and whetherwe're doing out of band monitoring on them.Signed-off-by: David Hunt Acked-by: Radu Nicolau List of files: /dpdk/examples/vm_power_manager/Makefile

fa47405c - ethdev: remove experimental flag of ports enumeration

Tue, 24 Apr 2018 02:15:11 +0000

ethdev: remove experimental flag of ports enumerationThe basic operations for ports enumeration should not beconsidered as experimental in DPDK 18.05.The iterator RTE_ETH_FOREACH_DEV was introduced in DPDK 17.05.It uses the function the rte_eth_find_next_owned_by() to getonly ownerless ports. Its API can be considered stable.So the flag experimental is removed from rte_eth_find_next_owned_by().The flag experimental is removed from rte_eth_dev_count_avail()which is the new name of the old function rte_eth_dev_count().The flag experimental is set to rte_eth_dev_count_total()in the .c file for consistency with the declaration in the .h file.A lot of internal applications are fixed to not allow experimental API.Fixes: 8728ccf37615 ("fix ethdev ports enumeration")Fixes: d9a42a69febf ("ethdev: deprecate port count function")Fixes: e70e26861eaf ("net/mvpp2: fix build")Signed-off-by: Thomas Monjalon Tested-by: David Marchand List of files: /dpdk/examples/vm_power_manager/Makefile

8728ccf3 - fix ethdev ports enumeration

Thu, 05 Apr 2018 15:33:20 +0000

fix ethdev ports enumerationSome DPDK applications wrongly assume these requirements: - no hotplug, i.e. ports are never detached - all allocated ports are available to the applicationSuch application iterates over ports by its own mean.The most common pattern is to request the port count andassume ports with index in the range [0..count[ can be used.There are three consequences when using such wrong design: - new ports having an index higher than the port count won't be seen - old ports being detached (RTE_ETH_DEV_UNUSED) can be seen as ghosts - failsafe sub-devices (RTE_ETH_DEV_DEFERRED) will be seen by the applicationSuch mistake will be less common with growing hotplug awareness.All applications and examples inside this repository - except testpmd -must be fixed to use the iterator RTE_ETH_FOREACH_DEV.Signed-off-by: Thomas Monjalon List of files: /dpdk/examples/vm_power_manager/Makefile
