06:05:31braewoodsdesowin: really? that's more useful than expected.

06:49:16desowinand it is on spi0 (toget with atmega) not on sdio
06:50:34braewoodsdesowin: so what do you plan to do with the wifi?
06:50:48braewoodswe would need a whole IP stack plus a wifi stack just to use it
06:51:48braewoodsthough it would open up some interesting options
06:52:41braewoodsgiven that i expect the main purpose of a driver is to optimize powersavings

07:32:01dbohdanLooks like my Clip+ has finally died
07:32:16dbohdanIt served me well for a decade
07:32:33dbohdanThanks to everyone who has worked on Rockbox for making it so nice to use
07:32:57braewoodsdbohdan: so what can we do for you?
07:33:51dbohdanNothin'
07:34:07dbohdanI just thought I'd show some appreciation for a piece for software I really like
07:35:41dbohdanI may have questions about what to buy to replace the Clip+ once I survey the local old audio player market
07:35:59braewoodsi see.
07:36:24braewoodsi have some HDD units that work well still. repaired and all typically.
07:36:45braewoodsif you live in the US i can sell 'em to you.
07:36:52braewoodslet me know what you find.
07:37:16dbohdanThanks, but unfortunately am cut off from international mail
07:37:26dbohdanThings would be much easier if I wasn't
07:37:35braewoodsah so you live elsewhere
07:37:35dbohdan(I am not in the US.)
07:37:45braewoodsok, some recommendations then
07:38:10braewoodsiRiver H100 series or H300 series are both good ports; old and reliable. main drawbacks are...
07:38:24braewoodsno softwate usb stack, only hardware UMS or MSC
07:38:53braewoodsbut they use standard connector types for power and data
07:39:04braewoodsno special cables needed
07:39:11desowinDoes someone speak Chinese here? GSPI-8686-LINUX26-BULVERDE-7.70.5.p4-26313-all.zip seems to be available on some Chinese websites, but I have no clue how to get it...
07:39:40braewoodsdesowin: unfortunately no. we ran into a similar problem with a datasheet for a mips chip.
07:40:19desowinthere's also a newer one GSPI-8686-LINUX26-BULVERDE-9.70.3.p20-26409.P42.zip
07:40:23braewoodsdbohdan: the iriver H10 is also viable. stick to the fat model though, the 20GB one.
07:40:43dbohdanbraewoods: Noted. I'll check if there are any for sale on the local Craigslist clone.
07:40:52braewoodsdbohdan: those 3 irivers are the best option from iriver we have
07:41:27braewoodsthey have compatibility with the same battery type
07:41:42braewoodsand you can also CF mod them all
07:42:33braewoodsi would avoid any flash based units that lack SD card slots
07:42:45braewoodsthey can't be upgraded
07:43:08braewoodsall the sansa ports now though support multiboot for running entirely off the sd card
07:43:14braewoodsso you can preserve the internal flash
07:43:55braewoodsHDD units can be CF modded in most cases
07:44:06braewoodsSD card to CF card is also a thing
07:44:20braewoodsif real CF cards don't provide enough storage
07:45:09braewoodsoh, right. if you get the H100 or H300, make sure to flash the new bootloader before trying to do a CF mod.
07:45:36braewoodsi released new bootloaders that fixed some old bugs with it
07:45:40braewoodsand the OF doesn't like CF cards
07:45:46braewoodsso don't expect it to work with them
07:49:04dbohdanOkay, I've checked, and there are no iriver H10/H100/H300 players for sale near me
07:49:46dbohdanI think I'll just go through the entire list of supported hardware later and search for each model
07:55:14cockroachdbohdan: where do you live? I own an H140 that has seen better days but might be good enough for a bit of testing
07:56:18cockroachor, I could also test things myself, if you tell me what needs testing
07:58:31dbohdancockroach: I live in the LPR
07:58:53dbohdanhttps://en.wikipedia.org/wiki/Luhansk_People%27s_Republic
08:00
08:00:38cockroachoh wow, that looks like an interesting place
08:01:26dbohdanIt is
08:01:51dbohdanSadly, we can't simply buy things off Amazon or eBay and have them delivered
08:05:14cockroachyeah, I was just wondering about that. international shipping must be a pain.
08:19:23sporkfiio m3k might still be available
08:20:21dbohdancockroach: Yes, it typically involves an intermediary
08:20:54dbohdanWe have one that specializes in AliExpress packages, so that's an option, but I haven't used them
08:23:06dbohdanspork: I can only find local ads for the FiiO X1

08:28:32speachysince you're the resident gui expert. :)
08:29:20braewoodsdbohdan: ask here first though. some models are less desirable for various reasons.
08:30:02sporkdbohdan: local is always hard, m3k might be on aliexpress still if that is an option
08:32:33Bilgusspeachy thats an oldie but a goodie I think
08:33:17BilgusIIRC I had to do special ordering with viewports to work around that bug
08:33:43Bilgus(in themes)
08:34:59dbohdanbraewoods: I definitely will!
08:36:32dbohdanspork: I agree about local. I still want to try local first, though, because it is faster and you don't have to worry about a package getting lost.
08:38:37speachyBilgus: One has to wonder how many more of these longstanding "features" are still lurking, eh?
08:39:02BilgusIDK how many features do we have?
08:39:18speachydunno, all of them?
08:39:18Bilgusmultiply by 100 and you might be close
08:40:51Bilgusthat theme engine is an unforgiving SOB too
08:43:45speachyjust for giggles, a first pass with sloccount says we have a bit under 1.5M lines of code
08:44:25speachy~1.4M C, 57K C++, 31K asm, 8K perl, 7K sh, and some miscellaney.
08:49:18BilgusI'm thinking scroll_stop should be called unconditionally
08:49:58speachyI've seen plenty of places where scrolling ends up drawing over a fade, for example
08:54:24Bilgushttps://github.com/Rockbox/rockbox/blob/master/apps/gui/bitmap/list-skinned.c#L184
08:54:56Bilgusno clue why github couldn't bring me to this in search
08:55:23Bilgusits like their search function is worse than ever
09:00
09:01:08BilgusWe couldn’t find any code matching 'scroll_stop' in Rockbox/rockbox ?
09:01:27speachyha!
09:01:42BilgusWe couldn’t find any code matching 'printf' in Rockbox/rockbox

09:18:17speachyie we stop for the current viewport but leave the rest scrollnig?
09:18:28mendel_munkisBilgus: I stopped using github code search years ago due to lack of results
09:18:46Bilgussame but it seems even worse
09:19:01BilgusI'm not on my machine either so no local source
09:19:11mendel_munkiswell all the people who want good results stopped using it...
09:19:17mendel_munkisoh ouch
09:19:42Bilgusspeacht clear_viewport is supposed to keep track of all intersecting viewports
09:20:31mendel_munkisprintf site:https://github.com/Rockbox/rockbox ?
09:20:31Bilgushttps://github.com/Rockbox/rockbox/blob/master/firmware/drivers/lcd-scroll.c#L59
09:20:39mendel_munkison google
09:21:13Bilgusyeah thats how i did it lol
09:23:12Bilgussorry that was condensed a bit too far clear_viewport uis supposed to call scroll_stop_rect which should pick tup the colliding viewports and stop them
09:26:26Bilgusif (s->vp == vp
09:26:46Bilgusthat seems suspicious
09:27:46speachyso that can only ever stop the current vp
09:28:24speachyeven if it's in the rectangle
09:28:31Bilgusyeah
09:28:33speachyyeah, that does seem wrong
09:29:27Bilgushttps://github.com/Rockbox/rockbox/commit/50eb528bc1f9d2f7b7260eff8b85a5ed5b96e679#diff-0534850a6fe26d32cf6a1c48c7e2baafa4b6688459f33f3cf240882cd9188969L57
09:30:58desowinvitt13: sent you link in private message
09:31:32speachyso... if you take away the vp check there, that'll effectively make the call into scroll_stop_rect()
09:31:58***No seen item changed, no save performed.
09:32:30speachyand scroll_stop_viewport becomes effectively the same as a global scroll stop
09:32:37Bilgusgood point
09:33:05Bilgusso perhaps its more nuanced than that though
09:33:56speachyI mean, there's probably a clear need for a non-vp-specfic scroll_stop_rect() but the question is if we actually need non-bounded vp-specific scroll stop
09:35:08Bilguswell I can see the need to only stop foreground elements versus bg but we currently have no notion of priority
09:35:55speachyso maybe instead of if (s->vp == vp) it could be (!vp || vp == s->vp) && ,,,
09:36:23speachyand we can implement a global scroll_stop_rect() that way. if it's actually useful, anyway
09:36:54speachythere aren't many places where scroll_stop (or its variants) are called anyway
09:37:47BilgusI think that will work without breaking anything
09:38:54Bilgusyou don't really want to stop everything just stuff that will overwrite your vp
09:38:57speachybut as you said the problem might ultimately be that there's no priority. stop_scroll_viewport_rect() stops the entire scroll line, not just the portion that's within the bounding box
09:39:39speachycould that result in scollers that never resume?
09:40:27BilgusI hate to say it but really what should be done is to keep track in the scroll engine and have it implement priority
09:40:38speachyyeah
09:40:55Bilgusyou place a new vp in the scroll area it wont scroll into it till it is removed
09:42:59speachyhow does it end end back up in the scroll list after the vp is removed? won't it have to be re-added?
09:43:42BilgusI was just debating that
09:44:25Bilguscurently we just let you make viewports as you see fit we would need to keep a list
09:45:05Bilgusif we turn vp into an opaque container and give a generator and destructor
09:46:20Bilgusthen we leave them in the list and they won;'t redraw if there is something blocking them
09:47:02speachyyeah
09:48:27Bilgusthat also fits well with the vp rewrite
09:48:52speachyhmm. or maybe.. just add a "scroll inhibit" flag to the scroller, and make the vps themselves check/clear the scroll list upon creation/destruction time?
09:49:10speachycheck/clear the inhibit in the scroll list I mean
09:50:00Bilguscouldn't you make it automatic though just check the scroller on vp creation
09:50:12speachythat's what I meant
09:50:55speachyI mean, the "Correct" solution is proper vp prioritization so scrollers can do whatever they want
09:51:13 Join petur [0] (~petur@78-21-55-218.access.telenet.be)
09:51:35Bilguswe don't have a real idea when a vp is destroyed though do we?
09:51:52Bilguslike how would we un-inhibit?
09:53:25speachyhow do vps get registered with the display code?
09:53:32speachysurely there is a de-register too?
09:53:45BilgusI guess on vp change you would clear the flag
09:54:00Bilgusno you just select the next one no deregister
09:54:28Bilgusclear the flag and check again for intersections
09:54:36speachyI mean, if the vp isn't "active" then who cares? :D
09:54:37Bilgusit'd still be glitchy
09:54:42Bilgusbut better
09:55:04Bilgusat least the active one would be clear
09:55:06speachyhmm. would this just be another layered hack
09:55:26Bilgusit all is thats why I said 'I hate to say this'
09:55:36Bilgus:P
09:55:37speachythat we (meaning you) would have to undo when inevitably implement priorities?
09:56:20Bilgusbut its gonna take me 6 months to get to it
09:57:35speachybut going back to scroll_stop_viewport_rect() for a moment, you changed the semantics of that fucntion, dropping the "all lines if y < 0" clause
09:57:48speachyare any callers still expecting the old semantics?
09:58:03speachyoh wait nm.
09:58:06speachyline -> rect
09:58:21Bilgusyeah not my commit
10:00
10:01:07Bilgusultimately they could just prioritize their viewports as I did to work around the bug originally but what if we let them specify priotities in the theme engine
10:01:15Bilgusprobably a bigger can of worms
10:04:22speachywe'd need it independently of themes though?
10:04:51speachyand, heh, I doubt most themes are going to ever get updated.

14:47:32desowinapparently, the wifi module uses sif0 (15 MHz) while AVR uses sif1 (200 kHz)
14:48:22desowinand well, this wifi is like the perfect use case for ROCKCOM I mentioned earlier...
14:49:52desowinanother use case on Sansa Connect would be e.g. sending raw commands to AVR

15:08:59desowinbraewoods: Marvell firmware supports WPA2, so there's like nothing to be done on the host side, except from providing the password
15:09:41desowinbasically to get network going the Marvell driver has to be ported, hopefully the source code is GPL licensed so no problem here
15:10:06desowincombine that with lwip and you have networking, add mbedtls and you have tls
15:10:49desowinhowever, I might go only for the driver at most, leaving the rest for someone else :-)
15:11:53desowinthe firmware permits binary redistribution so that's probably ok for Rockbox (I guess that's first thing that would need binary blob)
15:13:36desowinthat's just three files in .rockbox directory (LICENCE.Marvell, gspi8686_v9.bin, gspi8686_v9_helper.bin)
15:16:14desowinofcourse that needs a ton of work on the user interface, which obviously need volunteer
