- Fixed missing bx_gui->flush() call after non-VGA update().
- Fixed a BX_DEBUG message in the Voodoo code.
- Re-define LOG_THIS for messages in the "Voodoo VGA" code.
currently only implements an ISA standard VGA adapter with the selected Voodoo
model as it's extension. The methods of the "Voodoo VGA" device only call the
required methods of the Voodoo or VGA core.
TODO: Start implementing the Voodoo Banshee chipset based on this code.
- Treat VGA extension name other than "none", "vbe" or "cirrus" as a VGA
compatible device plugin and try to load it.
- Added new plugin type PLUGTYPE_VGA for such a plugins (interally handled like
a core plugin).
- Added panic in devices init for the case no VGA compatible plugin is present.
- Added new method vga_redraw_area() that handles the non-VGA and null size
case. The specific method redraw_area() is called otherwise.
- Moved init_systemtimer() call from extension code to init_standard_vga().
- TODO: Implement VGA subsystem in the Voodoo code to test the new feature.
Voodoo Banshee 2D accelerator code needs to be written to make this really
useful.
- Added support for setting memory write handler to NULL (ROM case).
- Added new PCI device method after_restore_pci_state(). It currently handles
the PCI ROM case only (could be extended).
- Moved VGA timer handler to the VGA core and handle the non-VGA case there.
It calls the specific update() code and finally bx_gui->flush().
- Moved the VGA update frequency parameter handler and the refresh_disply()
method to the VGA core.
- Store the VGA extension parameter in the VGA core.
- Voodoo: Fixed graphics snapshot.
- Fixed probing the CMDFIFO with Voodoo output disabled (send FIFO wakeup
directly, otherwise driven by vertical retrace).
- Use the CMDFIFO member 'enabled' instead of reading the fbiInit7 register bit.
- TODO: The Voodoo2 freeze when testing a Voodoo1 demo is still not fixed.
- voodoo_init() must be called after initializing FIFO mutex.
- The 'op_pending' counter must be reset after resetting FIFOs.
- Fixed an MSVC warning and removed obsolete comment.
- FIXME: There are still some conditions that can freeze the Voodoo display.
it's 64 entries is still not present, since it makes the emulation a few
percent slower due to the overhead of the FIFO code. The memory FIFO has 64k
entries and makes a speedup of around 75 % possible.
- usb_msd.cc: The Device Qualifier is valid for high speed devices only.
- uhci_core.cc: Don't report BX_DEBUG message if the current TD belongs to an
async operation that is still not complete.
Here is his original comment:
I have made several improvements in the debugger.
I have fixed several issues with proper handling of 64-bit addresses, and added support for 64 bit symbols.
I also have added several symbol lookups.
- Now using float type for the 'clk0_freq' variable.
- DAC register 6 can switch to half pixel clock (ported from PCem).
- Writing value 0xf8 to PLL register 0x0e completes clock #0 setup.
non-WIN32 platforms instead of BX_MSLEEP(). The donut demo is once again a
little bit slower, but on other tests the IPS values are still okay. Cleaned
up the code a little bit and added save/restore stuff for the new code.
packets and then always sleep for 1 millisecond.
TODO: The first tests with pthread_cond_* stuff showed a slowdown of approx.
10 % compared with the IPS value of the current code.
