This improves the detection of the default speed of a device when given
in bochsrc.
It will first get the max speed of the port given. For example, uhci and
ohci will return FULL, ehci will return HIGH.
xHCI will return SUPER if the port is a super-speed port, else it will
return HIGH.
Then it will compare this with the max speed allowed for that device,
returning the highest common speed.
Of course, if the speed option is given, the above is overwritten by the
specified speed.
Both checks are still performed on the result.
1) does device allow the result speed?
2) does the controller allow the result speed?
This adds three additional checks to make sure the Guest is working
correctly.
- checks that the guest allocated the Scratchpad Area. If left zero
(NULL) the controller may access low memory.
- checks that the guest uses correct segment sizes in the interrupter
ring(s)
- checks the burst size value given to be within normal range
This also adds an internal register value for the HcCrcr (Command Ring
Control) register. Since this register reads zero by the Guest, we keep
an internal value so that the emulation can read the value, internally.
This is for features soon to be released.
Minor other syntax/comment changes (misspelled word, etc)
Checked with WinXP, Win7, and Win10
This fixes zero length packet handling.
See the following example that requests 128 bytes:
```
SETUP(8)
IN(64)
IN(64)
STATUS(0)
```
The current code erroneously assumes that there are no more IN packets
after the first two 64-byte packets.
However, what happens with the following:
```
SETUP(8)
IN(64)
IN(64)
IN(64) <--- current code assumes this will be, and expects a STATUS packet
STATUS(0)
```
Currently, the third IN(64) above will result in a coding error because
the code is expecting the STATUS packet, not another IN packet.
The "controller" must allow for more packets than expected, returning a
short packet detect on the third IN(64) packet shown above, actually
returning zero bytes, hence the Short Packet Detect.
This patch was tested on WinXP, Win7, and Win10.
The check for the amount of byte transferred in one frame time was done
before the update of the vertical pointer in the current Queue of the
last executed TD. Therefore, on the next frame time, the last executed
TD was being "executed" again. The check has now been moved to the top
of the loop.
This adds over-current signaling to the USBs four host controllers.
To signal an OC, use the runtime configuration and set the checkbox (GUI) or text config's parameter to 1.
This pull request also adds USB documentation to user.dbk.
The 'd.pcap_image_t pcapture' in usb_common.h called its constructor and set 'fd' to -1. However, in the usb_device_c() constructor, we then cleared all of 'd', resetting pcapture.fd back to zero. Then on Bochs exit, the pcap_image_t destructor tried to close the file since 'fd' was zero instead of -1. To fix this, I removed the pcap_image_t constructor and now call pcap_image_init() within the usb_device_c constructor.
Added examples for new options.
- xhci: model= option
- xhci: allow the user to select number of ports
- usb disk: proto= option (bbb or uasp)
Added xhci primary stream support.
(Secondary stream support is not included)
Added (experimental) usb disk protocol UASP for super- and high-speed usb disk devices.
(high-speed uasp support is not thoroughly tested)
xhci: fixed "change event" function
scsi: fixed bug in command 0x25
scsi: added command 9E/10
Minor:
Check speed indicator in the Transfer Descriptor matching the device speed.
Max packet size check, checking that the amount requested/sent is within limits.
Checking that the first packet sent is the GetDescriptor Request with a length equal to or less than the max packet size.
Checking the command length in the USB SCSI emulation.
Checking command parameters within various emulations (SCSI (BBB), etc.)
Implemented "Boot Protocol" for the (HID) Mouse emulation.
Fixed wheel mouse HID report (along with the other HID reports)
Added the Over Current bits to the UHCI code
Added the monitoring of the toggle bit in the TDs
Major:
Re-wrote the UHCI stack processing so that control and bulk reclamation can be used.
(This made it so Windows 7 now works)
Adding function to the USB SCSI emulation.
Enhanced the xHCI emulation to further check for errors in a driver.
- Added check in config.h whether or not Bochs is configured and compiled for
the same target platform (WIN32 / WIN64).
- Fixed some warnings that occur in the MSVC WIN64 case.
- Added simple clip check method to be called for each destination x / y change.
- Use the new clip check in both host-to-screen methods.
- Some related changes.
- TODO: verify other bitblt methods for clipping correctness.
- Calculate host-to-screen data size for "source stride packing" in color mode
similar to the monochrome mode.
- Set up data swizzle mode for all launch area operations.
- Temporarily draw polygon in normal mode in case the currently unsupported
pattern mode is selected.
- TODO #1: Rewrite of the clipping code at least for host-to-screen functions.
- TODO #2: Drawing polygon with pattern if requested.
monochrome source and "source stride" packing. Now adding the source stride
converted to pixels to the 5-bit srcX value.
TODO #1: color source needs to be handled in a similar way (no test case yet).
TODO #2: clipping needs to be rewritten at least for host-to-screen blts.
mode sets both banks to the same value. Reading VBE bank register always
returns the write aperture setting. This feature is designed for the scrolling
function of the VBE 'write character' support. VBE code should use compatibility
mode for now.
TODO: update VGABIOS to use this feature.
- VBE enable register returns 32k granularity flag if enabled.
- VBE bank register returns 32k granularity flag if VBE_DISPI_GETCAPS is set.
- Defining new DISPI ID not necessary.
- TODO: update VGABIOS to use this feature.
- Limit VBE bank size to 64k as expected.
- Enabling VBE mode now clears the whole video memory for all bpp modes unless
"noclear" bit is set.
- Prepared 32k bank granularity mode required for text output functions. Added
new VBE_DISPI_ID6 to indicate this capability. The default is still 64k.
- Added new files with small changes, output can be viewed with Wireshark.
- FIXME: Windows ports crash with original Win98 guest and USB disk connected.
- TODO: mention new feature in documentation.
- vgacore: method get_crtc_params() now returns selected video clock value.
- banshee: now using selected video clock instead of hardcoded VCLK #3.
- cirrus: added vertical frequency to mode switch BX_INFO.
- Moved setup of default i/o register values to reset().
- Set up strapInfo register bits in init().
- Don't overwrite readonly bits in miscInit1 register.
- Set up subsystem ID in VGABIOS ROM in case it's > 32k (doesn't exist yet).
- Copy subsystem ID from ROM to PCI config registers in reset().
