Anyone else testing ClassiCube?Hi Jochem,
Hello Tellie
Is it ok if I upload "xpdf-4.05-qt5-os2.7z " to hobbes with this readme?
Regards
trying it as command line:
mypdffile.pdf present in same working directory (bin) of xpdf.exe and other .exe
xpdf.exe mypdffile.pdf
SYS1804: The system cannot find the file PAPER1.
found no reference on the net about this missing file
Hi Tellie, how did you get cmake to find L:\qt6-2.x\lib\cmake\Qt6 for the IMPORTED_IMPLIB's for the various QT6 DLL's?
When I use dooble it takes minutes to scroll, I only have this with 2 laptops. I don't have this problem on my desktop comp. Even if I have to fill something out, it takes minutes.
Hi Rich,
First all the best for 2024 ....
I have (or had) this problem. Answer these questions to see if we have the same issue:
1) Are these machines able to emit a beep? Not a sound through the soundcard but a tone through the speaker or transducer on the mobo. If yes, it's a different problem.
Yes i hear a beep sometimes. Alto is a sound that i get when f.e running a app that i have compiled but it's gives a trap
2) After scrolling and finding that nothing happens, does moving the mouse around _a lot_ over the window cause the accumulated scroll actions to happen all at once?
Yes
3) Assuming you're running AOS, run 'ACPISTAT | MORE'. At the top is a list or IRQs and the number of times they've been triggered. Is the count for IRQ 0 very low (in hundreds or less) or is IRQ 0 simply missing (either of these may be true)?
The version of ACPI.PSD that is installed is 3.23.17
The system is operating in Symmetric mode (Mode 2)
The kernel is 14.204_SMP
The retail PSD is installed
Number of interrupts available: 60
IRQ 00 count 14
IRQ 01 count 1049
IRQ 08 count 1137885
IRQ 09 count 11
IRQ 16 count 513
IRQ 17 count 27
MSI 55 count 8201
MSI 56 count 77012
MSI 57 count 18757
If the answer to (1) is no but (2) and (3) are yes, then we have the same problem: the clock which feeds the 8254 timer circuit has been gated off.
The 8254 has 3 timers: one is used to make sound while another is used by many apps such as Dooble as a "high-resolution timer". To use it, the app sets a counter to the number of milliseconds required. Each clock pulse then causes it to decrement that counter. When that counter reaches 0, it issues an IRQ 0.
If the clock signal has been turned off, the counter never decrements, the IRQ is never triggered, and Dooble fails to scroll. There is one oddity here: for unknown reasons, significant USB activity (or at least, USB mouse activity) will trigger an IRQ 0. That's why moving the mouse may cause scrolling - it mimics the timer going off.
I spent a huge amount of time identifying the nature of the problem but never came up with a solution, only a work-around. The high-res timer can only be used by one app at a time. If it's busy, the app has to fall back to one of the system's conventional timers. So, I wrote a little util that claims the HRT for as long as possible to force Dooble and other stuff to use an alternate timer. This works fine for scrolling but multimedia performance is terrible - VLC is unusable.
AFAICT, only a firmware update would fix the problem - and that's unlikely because MS stopped using the 8254 in Win 7 or 8. Consequently there's no way to demonstrate to some Tech Support droid running Win 11 that there even is a problem.
