I want to go to sleep... 00:21:31 prpplague BZFlag: you'd be surprised how simple questions like that can be hard to find docs on 00:22:13 BZFlag erikm: I could mail em to ya to review when you get a chance. 00:23:25 Russ|werk BZFlag: I'll do a quick review if you like 00:24:00 BZFlag Russ|werk: cool. I copy you. 00:24:01 erikm BZFlag: ok, send them by email. I'll have a look at them on sunday 00:24:21 BZFlag email will have some known issues that are being changed in the next rev. 00:24:31 BZFlag I expect a new rev in less than a week. 00:25:15 BZFlag "I copy you" wow. I guess I can't think and type. I meant "I'll copy you" which you probably guessed. 00:25:29 Russ|werk prpplague: sorry, I meant arch-sa1100/irqs.h 00:26:08 BZFlag Russ|werk, erikm: either of you have SD/MMC designs? If so how did you attach them? 00:27:06 prpplague Russ|werk: there is also info there in the SA-1100.h file 00:27:38 BZFlag They are thinking of using the SPI mode on the uart. hmm.. 0 or 1? checking... 00:28:17 BZFlag 1 iirc. 00:28:56 BZFlag nope. I was wrong. it's 0 =( 00:30:03 prpplague Russ|werk: from SA-1100.h - #define IC_GPIO11_270x00000800/* GPIO [11:27] 00:30:29 Russ|werk ah, well, irqs.h is another good source for info anyway 00:30:43 Russ|werk BZFlag: what verbal NDA do you want? 00:30:50 erikm BZFlag: what do you mean with SD design? 00:31:30 BZFlag Russ|werk: you need to say "I won't pass this on to anyone without asking" ;-) 00:31:52 Russ|werk ok, I will not pass this on to anyone without asking 00:31:52 BZFlag sa11xx systems with a SD/MMC slot. 00:32:03 BZFlag Russ|werk: that will do. ;-) 00:32:33 Russ|werk oops, evolution has a vunerability in common with outlook 00:33:04 erikm BZFlag: ah, right. IIRC Steve Wiseman's balloon2 board has that 00:33:14 Russ|werk oh, nm, my asu.edu email servers fixed the email for me 00:34:18 Russ|werk a incorrect fix, but fixed none the less 00:34:20 erikm goes zzz 00:34:22 erikm bye 00:34:28 prpplague bye 00:46:47 prpplague http://www.abcsinc.com/small-linux/gpio-irqs.txt 00:46:55 prpplague BZFlag: check that out 00:47:06 prpplague Russ|werk: you too 00:47:22 prpplague see if there is anything i need to add or is incorrect 00:50:41 prpplague Russ|werk: looks like everything is set on the camion, it should go out monday or tuesday 00:52:35 Russ|werk cool 00:52:45 Russ|werk hmm...something is eating my memory... 00:54:54 prpplague Russ|werk: parana app? 00:55:23 prpplague Russ|werk: you look over the gpio doc? 00:56:59 Russ|werk it was galeon, one sec 00:59:44 Russ|werk you might mention something briefly about GPLR, GPDR, GPSR, GPCR, and GAFR 01:00:06 prpplague will do 01:00:11 Russ|werk and how for each GPIO there is a bit mask, a number, and an IRQ number associated with it 01:01:03 prpplague hmm, your right, i didn't explain that well 01:19:44 Russ|werk also, gives gpio 11-27 an chained irq number 01:19:53 Russ|werk s/ gives/linux gives/ 01:20:03 Russ|werk #defineIRQ_GPIO1132 01:20:03 Russ|werk #defineIRQ_GPIO1233 01:20:03 Russ|werk ... 01:20:27 prpplague yes i saw that, but i'm not sure how that is used 01:20:34 Russ|werk when you register it 01:20:46 Russ|werk there are a lot of steps you go though 01:21:12 Russ|werk GFAR, GPDR, set the edge, register the IRQ (I think thats right) 01:21:58 prpplague GFER and GPDR, ok 01:22:00 Russ|werk GFAR and GPDR take the mask, setting the edge might take the gpio or the irq, I forget which, and registering it takes the irq number 01:22:36 prpplague ok i'm with ya 01:23:19 Russ|werk request_irq and set_GPIO_IRQ_edge 01:23:57 Russ|werk (see arch/arm/mach-sa1100/irq.c) 01:28:04 prpplague Russ|werk: oh i see now, each GPIO has its own irq defined however, irq_gpio11 through irq_gpio27 only triger irq_gpio11_27 01:28:48 Russ|werk right, but it gets propogated to the right irq handler 01:29:13 prpplague Russ|werk: gotcha 01:29:34 Russ|werk sa1100_GPIO11_27_demux() 01:33:04 prpplague so after resceiving a irq_gpio11_27 the demux() polls each of the 11-27 gpios? 01:40:48 prpplague wb 01:40:58 prpplague did you get my last question? 01:44:19 Russ|werk take a quick look at arch/arm/mach-sa1100/irq.c 01:45:04 prpplague Russ|werk: ya thats where i'm looking 01:46:08 prpplague for (i = 11; i <= 27; ++i) { 01:46:08 prpplague if (irq & (1<<i)) { 01:46:08 prpplague do_IRQ(IRQ_GPIO11 + i - 11, regs); 01:46:08 prpplague } 01:46:08 prpplague } 01:52:17 russ_ just goes through, and sees what irq's need servicing 01:53:08 prpplague thats what i thought 02:02:23 Test Failed! 02:02:23 BZFlag ibot test 02:02:26 Test Successful! 02:02:26 BZFlag ibot test 02:02:29 BZFlag heh 02:03:27 Russ|werk: excuse me? 02:03:27 Russ|werk ibot: go test yourself 02:03:40 Russ|werk brb 02:06:11 prpplague Russ|werk: http://www.abcsinc.com/small-linux/gpio-irqs.txt 02:06:30 prpplague Russ|werk: i'll work on the control registers info a little more tomorrow 02:06:48 prpplague Russ|werk: but i think i got things strait 02:07:12 prpplague BZFlag: you welcome to add any additional info too 02:09:22 prpplague russ_: having problems? 02:11:52 russ_ testing stuff 02:11:59 prpplague ohh 02:12:24 prpplague russ_: well thanks for the 101 clas 02:12:27 prpplague clas 02:12:29 russ_ brb again 02:12:48 prpplague BZFlag: and thanks for the question 02:15:22 prpplague russ__: holy cow its russ, long time no see 02:17:45 russ_ last time 02:18:43 prpplague round n round he goes, where he'll no body knows 02:18:57 prpplague argh too much coffee 02:20:47 russ_ or not...going to just disconnect for a bit to avoid bugging people 02:21:12 prpplague ohh well 02:23:06 prpplague BZFlag: i'm out of here, thanks again, i know a guru like you don't need them much, but i've start collecting notes here - http://www.abcsinc.com/small-linux/notes.htm 02:26:32 BZFlag nice, I'll browse sometime. 02:31:29 prpplague later 06:23:32 Russ BZFlag: can you put that pdf up again? 06:37:33 Russ er, nm 06:45:01 prpplague Russ: should you be out at some college party or something? 07:14:32 Russ watching movie with girl 07:15:29 prpplague cat attention > /dev/gf 07:36:28 prpplague wb BZFlag Generated by irclog2html.pl by Jeff Waugh - find it at freshmeat.net!

`00:08:36`	`prpplague`	`Russ\|werk: i don't have a SA-1110.h in my kernel, is that part of a patch?`
`00:09:11`	`Russ\|werk`	`er, try SA-1100.h`
`00:09:21`	`prpplague`	`ohh`
`00:09:50`	`Russ\|werk`	`writing an email filter is fun`
`00:10:06`	`Russ\|werk`	`"there's a CR in the header field, outlook express chokes, mother it"`
`00:10:41`	`Russ\|werk`	`also, if a \r\n..\r\n crosses packet boundries between the .'s, outlook express will think the pop server signaled end of email`
`00:10:50`	`Russ\|werk`	`and then you can't get your email`
`00:11:20`	`Russ\|werk`	`both, along with dozens of other DoS and buffer overflow exploits are out there with no fix`
`00:11:23`	`prpplague`	`doh`
`00:15:47`	`prpplague`	`Russ\|werk: can you explain something about the SA-1100.h , the only gpio's associated with irq's listed there are 0-10, but erikm said 11-27`
`00:17:03`	`BZFlag`	`erikm: yep. thanx. /me feels like a hardware designer.`
`00:18:04`	`prpplague`	`BZFlag: mind if i ask what spawned you question?`
`00:18:09`	`BZFlag`	`11-27 all share one irq bit.`
`00:18:29`	`BZFlag`	`vercel http://www.vercel.com/ hardware folk asking me questions.`
`00:18:46`	`BZFlag`	`right now they have power buttons mapped to gpio26. this is not a good idea.`
`00:19:00`	`erikm`	`BZFlag: definatively not`
`00:19:07`	`BZFlag`	`power button(s) should map to some non-shared irq.`
`00:19:32`	`BZFlag`	`so I told em so. ;-)`
`00:19:42`	`prpplague`	`BZFlag: else events on the other gpios could be interepted as a power down?`
`00:19:52`	`BZFlag`	`erikm: want to review the schematics under a verbal NDA for me?`
`00:20:01`	`BZFlag`	`prpplague: exactly.`
`00:20:22`	`BZFlag`	`prpplague: well... actually it's the power up I'm worried about.`
`00:20:30`	`prpplague`	`BZFlag: mind if i write up a note on that?`
`00:20:43`	`BZFlag`	`knock yourself out.`

`00:46:55`	`prpplague`	`BZFlag: check that out`
`00:47:06`	`prpplague`	`Russ\|werk: you too`
`00:47:22`	`prpplague`	`see if there is anything i need to add or is incorrect`

`00:54:54`	`prpplague`	`Russ\|werk: parana app?`
`00:55:23`	`prpplague`	`Russ\|werk: you look over the gpio doc?`
`00:56:59`	`Russ\|werk`	`it was galeon, one sec`
`00:59:44`	`Russ\|werk`	`you might mention something briefly about GPLR, GPDR, GPSR, GPCR, and GAFR`
`01:00:06`	`prpplague`	`will do`
`01:00:11`	`Russ\|werk`	`and how for each GPIO there is a bit mask, a number, and an IRQ number associated with it`
`01:01:03`	`prpplague`	`hmm, your right, i didn't explain that well`
`01:19:44`	`Russ\|werk`	`also, gives gpio 11-27 an chained irq number`
`01:19:53`	`Russ\|werk`	`s/ gives/linux gives/`
`01:20:03`	`Russ\|werk`	`#defineIRQ_GPIO1132`
`01:20:03`	`Russ\|werk`	`#defineIRQ_GPIO1233`
`01:20:03`	`Russ\|werk`	`...`
`01:20:27`	`prpplague`	`yes i saw that, but i'm not sure how that is used`
`01:20:34`	`Russ\|werk`	`when you register it`
`01:20:46`	`Russ\|werk`	`there are a lot of steps you go though`
`01:21:12`	`Russ\|werk`	`GFAR, GPDR, set the edge, register the IRQ (I think thats right)`
`01:21:58`	`prpplague`	`GFER and GPDR, ok`
`01:22:00`	`Russ\|werk`	`GFAR and GPDR take the mask, setting the edge might take the gpio or the irq, I forget which, and registering it takes the irq number`
`01:22:36`	`prpplague`	`ok i'm with ya`
`01:23:19`	`Russ\|werk`	`request_irq and set_GPIO_IRQ_edge`
`01:23:57`	`Russ\|werk`	`(see arch/arm/mach-sa1100/irq.c)`
`01:28:04`	`prpplague`	`Russ\|werk: oh i see now, each GPIO has its own irq defined however, irq_gpio11 through irq_gpio27 only triger irq_gpio11_27`
`01:28:48`	`Russ\|werk`	`right, but it gets propogated to the right irq handler`
`01:29:13`	`prpplague`	`Russ\|werk: gotcha`
`01:29:34`	`Russ\|werk`	`sa1100_GPIO11_27_demux()`
`01:33:04`	`prpplague`	`so after resceiving a irq_gpio11_27 the demux() polls each of the 11-27 gpios?`
`01:40:48`	`prpplague`	`wb`
`01:40:58`	`prpplague`	`did you get my last question?`
`01:44:19`	`Russ\|werk`	`take a quick look at arch/arm/mach-sa1100/irq.c`
`01:45:04`	`prpplague`	`Russ\|werk: ya thats where i'm looking`
`01:46:08`	`prpplague`	`for (i = 11; i <= 27; ++i) {`
`01:46:08`	`prpplague`	`if (irq & (1<<i)) {`
`01:46:08`	`prpplague`	`do_IRQ(IRQ_GPIO11 + i - 11, regs);`
`01:46:08`	`prpplague`	`}`
`01:46:08`	`prpplague`	`}`
`01:52:17`	`russ_`	`just goes through, and sees what irq's need servicing`
`01:53:08`	`prpplague`	`thats what i thought`
