This commit is not breaking the current status, but adds the ability to build on the host, to simulate and (mainly) to help me hack the networking code in a simpler/faster environment. Missing features: - ptp - build in i386 (currently x86-64 is hardwired) Also, this commit requires a change in ppsi, that I'm not going to commit now: we must get rid of the main function (most of that stuff is done win wrc_ptp.c, which we must replicate in a unix-compatible way). This is the ppsi change --- a/arch-unix/Makefile +++ b/arch-unix/Makefile @@ -4,7 +4,7 @@ A := arch-$(ARCH) CFLAGS += -Itools -OBJ-y += $A/unix-startup.o \ +OBJ-y += \ $A/main-loop.o \ $A/unix-io.o \ $A/unix-conf.o \ Local changes in this commit: - adding CONFIG_HOST_PROCESS and the auto-generated opposites: CONFIG_LM32 and CONFIG_EMBEDDED_NODE (LM32 && NODE) - make some config option depend on !HOST_PROCESS - Makefile: some dependencies on HOST_PROCESS and the opposite - */*.mk: some dev and shell objects depend on CONFIG_EMBEDDED_NODE instead of CONFIG_WR_NODE (i.e.: both a node and an lm32) - new host/ subdir where some placeholders are placed - no sdb support on the host Signed-off-by: Alessandro Rubini <rubini@gnudd.com>

This, again, is preliminary to host builds, and has no effect. Signed-off-by: Alessandro Rubini <rubini@gnudd.com>

These changes have no effect at this point, but are the initial steps introducing host builds. Some changes are minor cleanups, some depend on CONFIG_HOST_PROCESS which is not defined at this point. Signed-off-by: Alessandro Rubini <rubini@gnudd.com>

We have three temperatures, called "roof", "core", "case" (yess rubi like word same lengt, s/he most love four). There is a "faketemp" command that can set one two or all of them. This allows to test negative temperatures in printouts (White Rabbit in Siberia does it, but we southish can't test easily). All temperatures are initialized to invalid. Example: wrc# faketemp -10 -2.5 wrc# faketemp fff60000 fffd8003 80000000 wrc# temp pcb:84.7500 roof:-10.0000 core:-2.4999 case:INVALID Signed-off-by: Alessandro Rubini <rubini@gnudd.com>

This costs anoter 220 bytes in the binary, becuase we now loop among all temperature providers in order to return data to the caller. The providers are clustered using an ELF section. Signed-off-by: Alessandro Rubini <rubini@gnudd.com>

This commit adds data structures, methods and a process to manage temperature. Currently the only temperature being read is the onewire thermometer, so there is no difference with what we had before. The cost is 1.1 kB in binary size. Well, there is a difference: only the stat engine was reading temperature, while now the thermometer is read continuously (every 15 seconds, or another Kconfig-urable interval). This takes quite some CPU time (18.5ms per polling loop, but allows any user to read temperature (using the API we now provide) without re-reading the onewire bus. The real aim of this is monitoring a board-specific set of sensors, as implemented and show in the next commit. Signed-off-by: Alessandro Rubini <rubini@gnudd.com>

Also, this changes how to mac address is retrieved in patching pfilter rules. I'd better use format_mac(get_mac) for the verbose message, so get_mac is also the source for patching the rules. register and get_mac/set_mac are guaranteed to be in-sync.

This allows a node built with CONFIG_VLAN to choose at run-time whether vlans are allowed or not. We build both pfilter rule-sets, and according to the active vlan number we write one or the other. The case "CONFIG_VLAN is not set" is handled by providing default NULL pointers for beginning and end of the vlan rule-set. As a side effect, I renamed the files and the functions in the pfilter-builder. This is how it works for me, with CONFIG_PFILTER_VERBOSE set, so you see different rule-set are used (29 rules vs. 16 rules): wrc# vlan set 0 0 ("0") out of range Command "vlan": error -22 wrc# vlan off fixing MAC adress in rule: use 22:33:44:55:66:77 pfilter rule 00: 4.00000000 pfilter rule 01: 1.e4466013 [...] pfilter rule 28: 8.00000000 current vlan: 0 (0x0) wrc# ip set 10.0.0.2 IP-address: 10.0.0.2 (static assignment) (and I am now reachable by untagged frames) wrc# vlan set 10 fixing MAC adress in rule: use 22:33:44:55:66:77 fixing VLAN number in rule: use 10 pfilter rule 00: 4.00000000 pfilter rule 01: 1.e4466013 [...] pfilter rule 15: 8.00000000 current vlan: 10 (0xa) (and I am now reachable on vlan 10) Signed-off-by: Alessandro Rubini <rubini@gnudd.com> Conflicts: Makefile

This allows a run-time change of the active vlan, if CONFIG_VLAN is active at build time. The pfilter rules are being rewritten every time the vlan is changed (and we have one VLAN only for the CPU). wrc# vlan set 0 0 ("0") out of range Command "vlan": error -22 wrc# vlan set pippo 0 ("pippo") out of range Command "vlan": error -22 wrc# vlan current vlan: 10 (0xa) wrc# vlan set 20 current vlan: 20 (0x14) wrc# ip set 192.168.20.2 IP-address: 192.168.20.2 (static assignment) (and the node now replies to ping on vlan 20) wrc# vlan set 10 current vlan: 10 (0xa) wrc# ip set 192.168.10.2 IP-address: 192.168.10.2 (static assignment) (and the node now replies to ping on vlan 10) Signed-off-by: Alessandro Rubini <rubini@gnudd.com>

This includes a wrs fix by Maciej and a change that prevents warning when bulding with CONFIG_HOST_PROCESS (which is not there yet). I prefer to merge this now, so the next commit picks only its own little change into the ppsi submodule. Signed-off-by: Alessandro Rubini <rubini@gnudd.com>

This commit adds the possibility to build an init command in the binary. It can be useful to install a number of nodes with a special configuration, without the need to reach the shell and/or eeprom of each one. This is useful, for example, to pass syslog configuration or the (yet to be implemented) definition of multiple vlans for etherbone and the wr fabric (frame classes 7 and 6 f the packet filter). Moreover, I personally love to load a master or slave node for testing without interacting with the node (or changing the flash over and over). This commit also makes reading of commands from storage an optional feature, but only in the advanced/developer options. Thus, you can build a wrpc that uses the build-time init commands, or the flash-stored init commands, both or none of them. Size effects: * no effect if you keep the defaults (no build-time init, flash init) * +248 bytes (+ the command itself) if you enable build-time init * -1696 bytes if you remove flash-based init (discouraged) Signed-off-by: Alessandro Rubini <rubini@gnudd.com>

WARNING: wr_switch_defconfig doesn't build, this is fixed in next commit Unfortunately this commit makes the internal communication between minic and lan asymmetric: on receive the tag is discarded (and the longer header falls into the payload) while on transmit it must be provided by lan.c. The reason is that on receive we can trim 4 bytes from the payload, but on send we can't add 4 bytes without a memmove. The functions receive pointers to two different header structures, so hopefully user errors will be signalled by the compiler. Still, users interact with net.c, which hides vlan completely from them.

We used to have "struct ethhdr" local in net.c, passing "void *hdr" to minic. We exports the structure to an header so to use it in communicating with the minic. Unfortunaltey, ethhdr is defined elsewhere too, so we'd better rename to wr_ethhdr. This is a step towards the introduction of vlans, but has no technical effect by itself.

This commit turns individual calls to polling functions into an array of tasks. On this basis we can add profiling and periodic execution (instead of continuous polling). Signed-off-by: Alessandro Rubini <rubini@gnudd.com>

The compiler is smart enough to turn this into a multiplication by 8: cf54: 3d c1 00 03 sli r1,r14,3 cf58: 59 a1 00 00 sw (r13+0),r1 and any real division by ll would be trapped by ./check-error.c . Still, I'd better simplify the code. Signed-off-by: Alessandro Rubini <rubini@gnudd.com>

All "tasks" must have the same prototype, so we'd better get void in all of them at the time being (so we only change the nerwork function). Meanwhile, use value "0" for "link down", so it can work as a simple enable flag for the IP polling code. (note: we query the link status in wrc_ptp_update() too, and we should rather refer to the global variable) Signed-off-by: Alessandro Rubini <rubini@gnudd.com>

This solves http://www.ohwr.org/issues/1218 We used to have a "needIP" variable, but we need three states: if the address was set by bootp, we run bootp again when the link goes up, but if it was a static assignment we do not (and keep the static one). So I renamend needIP to a 3-valued ip_status. The rename ensured the compiler found all users. Also, the messages are now 3-headed, so the user know whether the address is static or it comes from bootp. Signed-off-by: Alessandro Rubini <rubini@gnudd.com>
