| 13:36.00 | g1powermac_PB | hey prpplague |
| 13:36.12 | prpplague | g1powermac_PB: greetings |
| 13:36.22 | g1powermac_PB | how's it going? |
| 13:36.55 | prpplague | it's going |
| 13:37.28 | g1powermac_PB | yup, yup, same here |
| 13:38.39 | prpplague | g1powermac_PB: ask me again in about 25 days |
| 13:38.39 | g1powermac_PB | came awfully close to buying a small farm with house |
| 13:38.57 | g1powermac_PB | till the sellers didn't want to fix the problems with the house or lower the price |
| 13:39.09 | gandhijee | hey, how would you guys interface with an MDIO switch to manage it? my Design Engineer here keeps insisting we can hijack MDIO/MDC lines from an existing nic and use that to manage the switch |
| 13:39.15 | gandhijee | though that doesn't seem right to me |
| 13:42.40 | prpplague | gandhijee: MDIO is just a two wire interface, no reason you couldn't use two gpios or even a i2c controller with some tweaking |
| 13:42.54 | gandhijee | thats what i thought |
| 13:43.16 | gandhijee | two GPIOs? |
| 13:43.38 | gandhijee | wouldn't i need to use 3? 2 GPO's and a GPI? |
| 13:44.03 | gandhijee | unless i have a GPIO line i can toggle i guess from I to O |
| 13:45.07 | prpplague | gandhijee: correct, GPIO implies that the line can operate as Input or Output |
| 13:46.09 | gandhijee | if i just had a superIO that had it in banks, 4 GPO and 4 GPI, could i use a mux i guess to get the GPI and GPO pin on to the MDIO pin? |
| 13:46.12 | prpplague | gandhijee: it is all going to be dependent on alot of the psecs you need |
| 13:46.23 | prpplague | gandhijee: yea |
| 13:47.33 | gandhijee | prpplague: you know of any place i can source this info for my DE before he screws up the management portion of the switch? |
| 13:47.52 | gandhijee | also you guys know of any x86 devices that have a managed switched inside of them? |
| 13:49.17 | prpplague | gandhijee: there are plenty of documents on the internet for doing bitbang i2c, mdio is basically the same interface with a slightly different underlying protocol |
| 13:49.23 | gandhijee | the DE here is a very stubborn guy, does't really like to listen to people when he's wrong |
| 13:49.25 | gandhijee | got ya |
| 13:49.27 | prpplague | gandhijee: just look for "bitbang gpio" |
| 13:49.38 | gandhijee | thats what i used the last time |
| 13:49.38 | prpplague | gandhijee: believe me, i know all too well |
| 13:49.51 | gandhijee | then he came back at me with MDIO is a mutlidrop bus |
| 13:50.29 | gandhijee | we can just hi-jack the MDIO lines of the existing NICs and use that to configure the switch |
| 13:54.21 | prpplague | gandhijee: that is doable, however it makes the software a mess and invites the possibility of timming issues within the software |
| 13:54.46 | gandhijee | prpplague: i figured it'd be more of a mess to implement |
| 13:55.00 | gandhijee | as we'd actually have to mess with the driver source and hence kernel code |
| 13:55.04 | prpplague | gandhijee: yea |
| 13:55.12 | gandhijee | while the other way i believe we can operate in just user space |
| 13:55.21 | prpplague | gandhijee: if you don't want to jack with the driver, best you use dedicate i/o |
| 13:55.31 | gandhijee | and if they guys that want this design with Windows |
| 13:55.50 | gandhijee | and we hijacked MDIO we;d have to create a whole new driver and stuff |
| 13:56.52 | prpplague | gandhijee: exactly |
| 13:58.39 | gandhijee | cool. thanks for helping me out with that |
| 13:58.49 | prpplague | np |
| 13:59.24 | gandhijee | you don't know of any x86 devices that have a manged switch inside do you? |
| 14:00.43 | prpplague | gandhijee: sorry no, we haven't done x86 design in years |
| 14:00.56 | gandhijee | oh no, i didn't mean like that |
| 14:01.06 | gandhijee | i was just wondering if you'd heard of any |
| 14:06.05 | gandhijee | regardless, i really do appreciate your helping me out with the MDIO/MDC thing and making it a little clearer in my head |

| 17:35.02 | prpplague | solar: yea, i found the scm pdf for apm |
| 17:35.50 | prpplague | solar: acpi, as i understand it, does really have all the support needed for communicatiom/emulation between drivers for embedded items like a handheld |
| 17:37.06 | prpplague | solar: apm has support for stuff like power events trigger from the input layer, battery apm emulations, and suspend/resume events from machine specific sections |

| 17:57.01 | prpplague | ds2: yes they are |
| 17:57.29 | prpplague | ds2: /proc/apm is mainly used for debugging APM to make sure it is parsing the correct values |
| 17:57.43 | ds2 | then why do you need APM? |

| 18:07.44 | prpplague | ds2: i am sorry i do not understand your question |
| 18:09.30 | prpplague | ds2: APM is handling the managment of a primary battery, backup battery, three chargers, as well as a number of suspend/resume functions |
| 18:16.02 | prpplague | ds2: i.e., /sys/class/power-supply/m8050_battery/time_to_empty_avg might report that you have 132.5 minutes left, but /proc/apm might be grabing the information an presenting it at 13.25 hours left |
| 18:21.10 | ds2 | prpplague: hmm |
| 18:21.31 | ds2 | prpplague: for the other things(besides battery mgmt), APM isn't needed |
| 18:22.15 | prpplague | ds2: for example? |
| 18:23.37 | ds2 | <PROTECTED> |
| 18:25.53 | prpplague | ds2: that is very clunk if you have a "power button" as part of a keyboard matrix |
| 18:27.09 | ds2 | prpplague: true but APM doesn't work everywhere... I don't think you can emulate APM on top of ACPI for instance (correct me if I am wrong) |
| 18:27.30 | prpplague | ds2: correct, hence the reason no acpi |
| 18:28.02 | ds2 | prpplague: I guess I am used to having userland shims to do that stuff |
| 18:28.03 | solar | yeah apm and acpi do not play along. acpi is really what they intended for people to use >2.4 kernels. He must have his reasons |
| 18:29.01 | prpplague | ds2: main reason is ease of usage and the ability to connect different kernel drivers together easily |
| 18:30.37 | ds2 | prpplague: the trend seems to be to put such connections in userland |
| 18:31.49 | prpplague | ds2: yea i can understand if it was a laptop, but generally for the handheld stuff, it makes much more sense to keep in the kernel, imho |
| 18:33.59 | ds2 | prpplague: my concern would they might take out the APM emulation layer |
| 18:35.05 | prpplague | ds2: i don't think that is going to happen anytime soon, and even so, AML rarely upgrades their kernel after they have it workin |
| 18:35.42 | ds2 | prpplague: I deal with different dynamics where it is "fashionable" to get burnt on the bleeding edge :( |
| 18:35.53 | prpplague | indeed |

| 18:36.11 | ds2 | heh |
| 18:36.49 | ds2 | prpplague: do you guys have a sales tax in TX? |
| 18:36.59 | prpplague | ds2: indeed |
| 18:37.11 | ds2 | hm |
| 18:42.31 | prpplague | ds2: why? |
| 18:45.16 | prpplague | ds2: the apm emulation is pretty robust |
| 18:51.02 | ds2 | prpplague: why? looking for a cheaper place to hibernate if things continue in the current trend :( |
| 18:51.24 | ds2 | prpplague: same could be said about some of the useful stuff that got taken out |
| 18:51.46 | prpplague | ds2: indeed, i can't worry myself about that type of thinking |
| 18:52.15 | prpplague | ds2: hiberbate? you mean move to texas? |
| 18:52.26 | ds2 | prpplague: I don't worry about it... I just don't use it ;) |
| 18:52.50 | ds2 | prpplague: not move.. just a state to live in, hobo fashion, for a short period of time til things recover |
| 18:52.50 | prpplague | ds2: hehe, just different goals |
| 18:52.57 | prpplague | ds2: ahh |
| 18:53.10 | ds2 | sales tax is the biggest costs factor that I can change by just going elsewhere |
| 18:53.16 | prpplague | ds2: well we have sales tax, but no state income tax |
| 18:53.35 | ds2 | prplague: ain't going to have an income in that scenario so that don't help |
| 18:53.45 | prpplague | ds2: sales tax is pretty small, most places it's around 8% |
| 18:54.04 | prpplague | ds2: hmm ok |
| 18:54.16 | ds2 | 8% is lower then CA right now but I don't think 1% is going to make a big enough dent |
