00:10:32gartraland i cant get a sim build too work
00:11:31Bagdergartral: what happens?
00:12:51gartralthe sim wont even load
00:13:10Bagdercan you be more specific?
00:13:24Bagderthat dev environment do you use?
00:13:26Bagderwhat
00:14:03gartrali built a sim build, and i ziped the simdisk dir, and transfered to my comp and unzipped into the local simdisk, replacing what was there, and now the sim is busted
00:14:26saratogatry make install instead of make zip
00:14:35saratogato rule out other problems
00:14:36gartrali use the build enviroment that JdGordon has, as its his system i build from

00:14:59saratogayou'll probably need to run it on his system then?
00:15:06Bagdergartral: well, without more specific details it sounds as if your two systems are similar enough then
00:15:22Bagderare not
00:15:27Bagderdarnit I should go to bed instead
00:15:30gartralwhat do you mean?
00:15:53Bagdersomething prevents it from running on your system
00:16:09Bagderpossibly because your system differs from jdgordon's somehow
00:16:19gartrali figured that
00:16:48gartralbut why would it be different if all im changing is the .rockbox directory?
00:16:59Bagderyou tell us!
00:17:17BagderI'd use strace or gdb to find out on a linux box
00:17:21gartrali dont understand what you mean
00:17:52saratogatheres probably some difference between your systems like OS versions, bitness, etc
00:18:05gartralwell, my system is windows, his is linux, i know i cant make the executable work, but why would the base files fail?
00:18:23saratogabacause they're compiled for linux and you're not running linux
00:18:43 Quit BHSPitLappy (Remote closed the connection)
00:19:12saratogaif you want to run the sim on windows you'll need to compile it for windows, unless Jdgordon already did that for you
00:19:40amiconnAnd you'll obviously need sdl.dll as well

00:21:12gartralhow do i cross compile for windows
00:22:28saratogai think the easiest way is to setup the dev environment on windows and run it in there
00:22:37amiconnhttp://www.rockbox.org/twiki/bin/view/Main/UiSimulator#Building_Windows_sim_in_Linux
00:23:01gartrali just dont understand why the applications and such need compiling for windows if there for rockbox...
00:23:06linuxstbgartral: Or you could just download a binary for Windows - the same UiSimulator wiki page has links.
00:23:27Bagderor just build and run it on linux...
00:23:32linuxstbgevaerts: That wiki page also has a useful description of what the sim is...
00:23:42linuxstb(sorry, I meant gartral)
00:23:45gevaertslinuxstb: thanks :)
00:23:52saratogawindows can't run linux programs
00:24:01saratogathis is the answer to your question

01:26:13UnhelpfuljhMikeS: not frustrations, so much as wondering which wrappers we can remove. i guess the cache function ones seem to be more about allowing direct calls to inline versions on some targets, and using the API on others, than about hiding the API in general?
01:27:56Unhelpfulamiconn: is there a separate 32x32->32 multiply on arm? if that's just umull + discard bottom half, i'd like to keep the present code on arm, since it has 7 bits more precision and no actual shifts
01:28:19amiconnOf course. Just 'mul'

01:32:03Unhelpfulif we use mul, there would be a shift though, right? the shift comes for free with umull, since the output is in two registers.

01:33:17amiconnThe shift might also be for free, depending on how the mul result is processed further
01:33:42Unhelpfulit would be >>24 after the mul
01:34:18amiconnYeah, it depends on the instruction that processes the 'mul' result
01:34:32saratogamany arm instructions can shift their inputs, so the shift is probably free
01:35:01amiconnThey can shift one of their inputs

04:30:43*Unhelpful didn't know about the ability of arm to apply shifts to arguments of other operations, either
04:31:08Unhelpfulso i'll be testing if the >>24 version without the 32x32->64 multiply is faster on arm as well
04:31:37saratogaif it saves a multiply i would expect it to be
04:32:21saratogathats pretty much what all codec optimization on arm is, trying to figure out how to not multiply numbers
04:33:01Unhelpfulthere's still a multiply. amiconn said 32x32->64 costs a cycle more than 32x32->32, so the real question is whether we end up losing that cycle with the need to shift the value in the shift24 version
04:33:18saratogai wouldn't worry too much about saving one clock
04:33:25saratogaunless you're going to do that multiply a whole lot
04:33:48Unhelpfulper output pixel in the scaler.
04:34:00saratogathats nothing
04:34:09saratogayou'll never have even a million output pixels
04:34:46Unhelpfulheh, true
04:34:56saratogaat that point you're probably better off unrolling the loop in ARM asm to save all clocks wasted on the branch and lw instructions

04:36:37 Part tseymour
04:37:14Unhelpfulwould unrolling the loop in asm really be much more worthwhile than unrolling it in C?
04:37:25saratogadepends how much faith you put in gcc
04:37:46saratogai've beaten it by a lot, and also found times where i could do no better

04:38:07Unhelpful...i've had it produce broken code when hand-unrolling a loop in C :/
04:38:08saratogafor very tight loops its often worth trying since the effort is small and saving even a few clocks on unrolling can make a big difference
04:39:01saratogabasically look for anytime you do a lot of "load, mult, store" loops, as those can often beat GCC by unrolling 2 or 4x, then replacing the lw with load multiple ops
04:39:43saratogaparticularly for PP, since load multiples are almost twice as fast as load singles
04:39:52 Join jhulst [0] (n=jhulst@unaffiliated/jhulst)
04:40:26*Unhelpful would think that gcc would know how to do that itself...
04:42:15Unhelpfuli guess everything ARM has decent memory, as well, ie, nobody will kill me if a loop unroll adds a few bytes...
04:47:35saratogaunrolling is tough for compilers, since it wastes a lot of space and its not always clear if its worth it at compile time
04:47:44saratogaand gcc for arm is not the smartest compiler
04:48:12Unhelpfuli'm guessing that gcc is not able to turn that into a shift+<otherop>, and is adding an explicit shift, because the shift24 version is slower than the shift32 version with its free shift
04:48:34Unhelpfulon e200 - PP 80MHz, right?

04:50:11Unhelpfulwell, in any case, i seem to have a working scaler that never needs 32x32->64 mul, and i'd like to use that version wherever we don't have that operation in hardware... sounds like everything besides arm>4?
04:50:32saratogaUnhelpful: its pretty easy to objdump your own code and see what gcc is doing
04:51:15saratogajust add whatever that compiler switch that leaves in the debug info to your makefile, and then arm-elf-objdump it
04:51:17Unhelpfulyes, but i don't know much at all about arm asm... so it was also pretty easy to count ticks, then make my e200 load a huge image while nothing else is happening
04:51:43saratogai don't really know anything about it either, but if you're just mutliplying, adding, shifting, loading and storing you ddon't need to know much

07:33:14amiconnUnhelpful: Iirc a 32 bit division on SH1 would be faster than any multiplication involving 64 bits on it (using the libgcc routines)
07:35:00amiconnThis is because the division is done in asm, using SH1's division support instructions. This takes 64 cycles + some pre/postadjustment + function call overhead. The 64 bit multiplication stuff is plain C.
07:35:07Unhelpful amiconn: the SC_SHIFT = 24 case has enough overhead that one can expect the values not to overflow when multiplying by 63... so using /255 there is fine
07:35:25amiconnThe worst is divisions involving 64 bit, of course

07:38:32amiconnSo basically you need 32*32->upper32 multiplication?
07:39:43Unhelpfulas it's written now, yes. the >>24 version gets by without. i can't say precisely where it the reduced precision starts to be noticeable, but white is still white up to at least 250K pixels input in the downscaling case
07:42:37Unhelpfulthe kind of graphics work i've done in the past was mostly with mmx... which is generally beastly, but has some vector NxN->topN instructions that are just too conveniently abused for fixed-point stuff

10:44:54Casainhohello :-)
10:45:45Casainhodoes anyone knows if there is some target player that uses SPI SD Card communication? - I am looking for SPI drivers for SD card... and not SD BUS card drivers...
10:47:11 Quit rocko_ ("Leaving")
10:47:14lucentCasainho: not related to rockbox but there's openwrt.org drivers which do this off an LED light signal
10:47:23advcomp2019Zagor, i might go and pick up another to see if i get lucky again in getting a v2 fuze so i can try some code out
10:48:20Casainholucent: thanks - I will then look for that drivers. I saw a lot of drivers for 8 bit MCU as AVR, etc... however I am having problems doing software reset to the card :-(
10:51:27amiconnCasainho: Ondio does SPI for MMC
10:51:39Casainholucent: :-) −− there is a lot of pages talking about that SPI drivers ;-)

14:38:47kadobanwhich kind of defeats the purpose
14:40:16kadobanthe only thing that i can guess is that it's because the simulator never exits on its own so i have to kill it. does the prevent the final bit of information being output to the file or something? (is there a way to make the simulator exit more cleanly?)

17:25:50ajbGodEater_: well more of a cross project. Afterall the emulation of the device would have to be very driven by what Rockbox knows about them. But I take your point

18:08:51saratogais it possible to recover a T you think?
18:08:59toffe82from what I saw when I open it
18:09:10toffe82check the picture on the wiki
18:09:20saratogathe hardware is the same but that doesn't mean all the GPIO pins are wired the same
18:09:37saratogaevery single chip on the fuze and clip is the same, but the wiring is a bit different for instance
18:09:44jhMikeSI'd do some investigating and disable alot of stuff before assuming that. It could do nasty things if some key things differ.
18:10:14saratogais it possible to unbrick the T?

21:34:35philipsgevaerts: hmm, OK
21:34:46Learsaratoga: You can't rely on the other tables being small though. I've seen some pretty large chunk-related tables (hundreds or maybe even thousands of entries).
21:35:38saratogaLear: the chunk table can never be more then 2x the size of the samples table, and typically its much smaller so I'm not sure it matters

23:15:01amiconnIf you don't have the necessary hardware to test an asm optimisation on, someone else should probably do that optimisation
23:15:26amiconnThe emac scale factor can only do >>1 or <<1, and only in integer mode
23:15:42Mode"#rockbox -o Zagor " by Zagor (n=bjst@rockbox/developer/Zagor)
23:15:53Unhelpfulisn't integer mode what i want, for unsigned?
23:16:21amiconnIf we want to "misuse" the emac for an unsigned 32*32->high 32, we need some clever tricks.
23:16:52amiconnemac can be used signed or unsigned in integer mode, but only signed in fractional mode (which you need to get to the high bits)
23:17:10Unhelpfulahhh.. that's problematic. but maybe not. :)
23:18:13Unhelpfulthe scale factor only has 31 bits of precision, to avoid needing a 64-bit division to calculate it
23:19:13amiconnWell, if we can shift both factors right by 1, it becomes fairly simple
23:20:57Unhelpfulwe can already shift ctx->divisor right by one, it's calculated as (0x80000000/div) << 1 to avoid a 64-bit divide
23:21:25 Nick JdGordon|zzz is now known as JdGordon (n=jonno@rockbox/developer/JdGordon)
23:22:26Unhelpfulthe other factor, we may not need to... it is, at maximum, equal to 255*w*h, where w and h are the larger of the source or target dimension in that direction.
23:23:14 Join MethoS [0] (n=lem@dyndsl-085-016-165-048.ewe-ip-backbone.de)
23:24:16amiconnHmm, if the other factor is guaranteed to stay <2^31, it'd be even better.
23:24:17Unhelpfulso, it will be 31 bits or less all the way up to 2901x2901
23:25:19amiconnemac in fractional mode actually gives you bit 31..62 in the accumulator, so if one factor is shifted right by 1 and the other is guaranteed to stay positive, the result won't need shifting at all
23:25:23Unhelpfulwell, we can remove the left shift when calculating the divisor, and the other factor is guaranteed to be <2^31 if the source bitmap has less than about 8.4 million pixels
23:25:44amiconnThe question is whether we can drop the calculation of the low bits. We'd loose a bit of precision
23:26:10Unhelpfulnot sure what you mean by "drop the calculation of the low bits"?
23:27:04amiconnFor a true 32*32->64, we'd need a mulu.l (producing the low bits)and a mac.l (producing the high bits, with emac in fractional mode)
23:27:40Unhelpfulthe low bits are discarded entirely, though...
23:27:41amiconnSince we only need the upper 32, all the low bits would contribute would be a bit of rounding
23:28:04amiconnIf we drop them, we don't even need to perform the mulu.l
23:28:56Unhelpfulthey're already dropped entirely on arm. unless you're saying that the top 32 will lose some precision if we don't have a mulu.l to produce the bottom 32?
23:29:29amiconnBtw, there's a trick for reconstructing bit 63 without accessing the accumulator extension register. We won't need that here though
23:30:02amiconnNo, just that you always round towards zero if you don't calculate the bottom 32 bit

23:30:38Unhelpfulwell, we actually add a rounding value before the multiply, at least on arm
23:31:10Unhelpfuland just discard the bottom 32 entirely
23:31:22 Quit domonoky (Read error: 104 (Connection reset by peer))
23:33:39Unhelpfulctx->round is half of the divisor (from before the reciprocal is calculated), so the (val + round) * recip >> 32 is (val + div/2) / div
23:35:11 Quit nibbler (Read error: 110 (Connection timed out))
23:36:24Unhelpfulctx->divisor is only truly the divisor until the top of scale_v_*, at which point it's replaced with (2^31 / divisor) << 1
23:37:33Unhelpfulso, it sounds as if, if we remove the <<1, mac.l and extracting the high bits gets us exactly the same result we have on arm... provided the image is never large enough for the pixel value to exceed 2^30

23:50:32Zagoramiconn: how did you measure the coldfire PLL locking time? it just struck me maybe we get equally fast clock switches with PLL bypass if we just don't change the VCO.
23:52:39Unhelpfulamiconn: if i'm reading the programmer's reference correctly, for the normal scaling case, i can actually use unsigned integer mode, with the desired result being in the lower extension byte
23:53:21 Quit tessarakt ("Client exiting")
23:53:38Unhelpfulfor the parcticular case that is being used in pictureflow, of rescaling the existing scale factors by 31/255 and 63/255, it's a little more complicated, because i want a 32-bit value back
23:53:42amiconnZagor: Hmm, did I say I measured it? I can't remember atm. Didn't Linus do that?
23:54:12Zagoroh. I'm not sure.
23:54:43Unhelpfulperhaps the right thing to do is to give a custom output plugin a function that can be called once, at the start of the image, to calculate its own scaling factors, or whatever else it might need.
23:54:54amiconnI think it could be measured using the user timer, but you need to accept a bit of uncertainty
23:55:11ZagorI'll see if a simple loop counter shows any difference
