We need an iBrowse replacement for 68k!!!

Great work. I've always wanted NetSurf to work without Ixemul so no FPU amigas with 030´s (ACA) have a chance to use it.

New build up.  This should fix the problem with the previous page appearing behind the current one. (edit: although it might blotch it out in the wrong colour depending on when you downloaded!)

If that works I'll enable P96

No improvement in the visuals. It still looks like this:

It seems a little bit faster but nowhere close to Arti's NetSurf SDL builds yet.

Disappointing.  I've done the P96 updates anyway, so try the one I've just uploaded and see how that works.

I'll have a think about why the page isn't clearing.

I've also had another go on my A1200 and managed to get the main window up.  I think it wasn't working before due to lack of memory, so I might invest in a 32MB SIMM to make it easier for me to test.

Something is messed up with the P96 visuals:

I thought NetSurf was pretty good on memory. I expect it should be usable with 32MB. Maybe you were out of chip mem before. Almost all 2MB of my chip mem is free because I was using RTG. If you were using AGA in a descent resolution and depth with a picture backdrop then you probably ran out of chip memory. You solved the chip mem problem though. NetSurf should easily run on any Amiga with 1 MB of chip mem .

Hmm, that can only be to do with how I'm allocating the off screen bitmap, as everything else is the same (except the bitmap code, which is clearly working).

Does the log show your screen as 32 or 24 bit? (depth= somewhere near the top)

Chip RAM seems fine - 1.8MB free at the point it crashes (I reduced it to a 4 colour hires screen . Only 90K of fast mem though! It plummets from 6 to 1 MB just before the window opens, so unless there's a bug causing it to soak up memory I don't think I can gain enough to make it get any further. That's with simple refresh windows and a small tile size. (edit: hold on, shouldn't it be using chip ram when fast runs out?)

I think the outline fonts are eating a fair bit (as well as being slow), looking at that code it's going to be easier to conditionally compile either for outline or bitmap fonts, rather than trying to support both. I might be able to make it a runtime option. I'll have a play with that when I have more time.

What log? The -v stderror? I have selected 800x600x32 BGRA (little endian) every time it has asked. I tried mask_alpha:0 in Choices with the lastest build but it didn't help. NetSurf does create a new user in Users with my name rather than "user" now.

Yes, chip mem should be used when fast memory runs out. It might keep you going but there is a big hit in speed when using chip mem instead of fast mem. What TCP/IP stack are you using? The selection of stack can make a significant difference in memory usage. If NetSurf would work without a stack online, you could load html from your hard drive for testing saving a significant amout of memory.

I might be able to make it a runtime option. I'll have a play with that when I have more time.

I don't know that the outline fonts are working. My font Choices that you had me configure ended up being changed to:

Code: [Select]


font_cursive:CGTimes


The new user in Users doesn't even have this.

[chris]

What log? The -v stderror? I have selected 800x600x32 BGRA (little endian) every time it has asked.

Yes, the -v log.  I added something to report the screen depth.  I know you're on 32-bit, but I'd like to know if that knows as it could be causing the off-screen bitmap to be set up wrong.

I've put a new build up anyway which might fix it, but if it doesn't I'll need to know what the screen depth is being reported as.

edit: I've just added the bitmap tiler as well, which might solve some other graphical glitches or (more likely) create some new ones.

NetSurf does create a new user in Users with my name rather than "user" now.

Somewhere along the line you've set or changed the USER env-var.

MiamiDx, which is probably not the best at memory conservation, given it uses MUI.

If NetSurf would work without a stack online, you could load html from your hard drive for testing saving a significant amout of memory.

Unfortunately it won't as bsdsocket is loaded by clib2, and there's not much I can do to stop it (and I'm not sure if it would work without it anyway, given there is sockets-related code in the main loop)

That's because I fixed the defaults slightly different to what I'd posted here.  Anything set as default gets removed from the config file.

Using the old build I get "amiga/plotters.c ami_init_layers 102: Screen depth = 24"

Edit: The new version is no better than the version before it.

Somewhere along the line you've set or changed the USER env-var.

It was probably as part of one of my scripts I use before programming, So NetSurf is multi-user on the Amiga .

MiamiDx, which is probably not the best at memory conservation, given it uses MUI.

Miami has a Reaction GUI option (I don't recall MiamDx getting one) which would share many of the Reaction GUI resources such as libraries, gadgets and images saving memory. I use the AmigaOS 3.9 version of Genesis which also uses Reaction. Roadshow may use the least amount of memory having no GUI.

Unfortunately it won't as bsdsocket is loaded by clib2, and there's not much I can do to stop it (and I'm not sure if it would work without it anyway, given there is sockets-related code in the main loop)

Bummer. Being able to work offline is a nice feature,

[chris]

Using the old build I get "amiga/plotters.c ami_init_layers 102: Screen depth = 24"

That *should* have been OK.  I think I'll have to change it so it creates a gfx.lib bitmap, given that seemed to work before.

So NetSurf is multi-user on the Amiga .

Sort of, yes.

Bummer. Being able to work offline is a nice feature,

It will work offline.... provided the TCP/IP stack is running

[chris]

OK, try the new build and see if that fixes the colour issues on P96.  If it doesn't I'll go back to Plan A.

Nope. I can't see any difference from the last build.

Hi Chris

IIRC P96 built in emulated CGX WritePixelArray worked quite nicely performing RGBA to CLUT conversions. As strange as it may sound perhaps you should use CGX functions, because P96 doesn't have public functions to do some stuff available in its CGX emulation. Doing the same with the native P96 functions was trickier.

If you are using a 24bit buffer CGX WritePixelArray will help although If I have read correctly you are using datatypes to convert to the screen format.

Perhaps you could make use of AWeb sources for dithering and scaling, these should be more or less optimized for 68k, maybe also image decoders. Render.library should also include optimized code for that.

You can easily detect if current screenmode is cgx or not.
  if (CyberGfxBase != NULL)
    if (IsCyberModeID(resultadoalloccgx.DisplayID))
      {
      printf("screenmode is CGX\n");
      } else {
      printf("screenmode is something else\n");
      }

IIRC you could also use CGX LockBitMapTags to discover if the screen's bitmap is clut, rgba and to lock it to draw directly with the cpu (remember to write the bytes/words/longwords in the same screenformat).

Only for <= 8-bit screens. Elsewhere I use p96WPA.

I've seen render library mentioned before, I intend to check it out as I'm well aware using datatypes to do the dithering isn't particularly quick.

I really don't want to do that, I'm using graphics.lib's drawing functions extensively. What I'm missing is a way to set the rastport colour directly like you can on OS4 and MOS, ie without using ObtainBestPen.

Sorry to be dumb, but where to you download the latest build and the source code?

Thanks

[chris]

Sorry to be dumb, but where to you download the latest build and the source code?

Build: netsurf_os3.lha (you'll need to use XAD to unarchive it)

Source: NetSurf git repo

I've just put a new build up (hopefully this one will work with p96 modes).
