Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

usb_serial: API all change USB serial likes to use port->tty back pointers for the real work it does and to do so without any actual locking. Unfortunately when you consider hangup events, hangup/parallel reopen or even worse hangup followed by parallel close events the tty->port and port->tty pointers are not guaranteed to be the same as port->tty is the active tty while tty->port is the port the tty may or may not still be attached to. So rework the entire API to pass the tty struct. For console cases we need to pass both for now. This shows up multiple drivers that immediately crash with USB console some of which have been fixed in the process.

USB: cp210x: relocate private data from USB interface to port This change is preparation for implementing a cp2108 bug workaround. The workaround requires storing some private data. Right now the data is attached to the USB interface and allocated in the attach() callback. The bug detection requires USB I/O which is done easier from port_probe() callback rather than attach(). Since the USB access functions take port as a parameter, and since the private data is used exclusively by these functions, it can be allocated in port_probe(). Also, all cp210x devices have exactly 1 port per USB iterface, so moving private data from the USB interface to port is trivial.

Fix this not by reverting but by adding the proper dtr_rts and carrier_raised methods.

[PATCH] USB: new cp2101 device By the way I have to ask you to add new (vid,pid) pair to cp2101 driver. This device is argussoft's avr in-system programmer AS3M, http://atmel.argussoft.ru/hard.htm it's based on cp2101 chip and works pretty well with the linux driver.

usb: cp210x: Update to support CP2105 and multiple interface devices This patch updates the cp210x driver to support CP210x multiple interface devices devices from Silicon Labs. The existing driver always sends control requests to interface 0, which is hardcoded in the usb_control_msg function calls. This only allows for single interface devices to be used, and causes a bug when using ports on an interface other than 0 in the multiple interface devices. Here are the changes included in this patch: - Updated the device list to contain the Silicon Labs factory default VID/PID for multiple interface CP210x devices - Created a cp210x_port_private struct created for each port on startup, this struct holds the interface number - Added a cp210x_release function to clean up the cp210x_port_private memory created on startup - Modified usb_get_config and usb_set_config to get a pointer to the cp210x_port_private struct, and use the interface number there in the usb_control_message wIndex param Signed-off-by: Preston Fick <preston.fick@silabs.com> Cc: stable <stable@vger.kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

USB: cp210x: relocate private data from USB interface to port This change is preparation for implementing a cp2108 bug workaround. The workaround requires storing some private data. Right now the data is attached to the USB interface and allocated in the attach() callback. The bug detection requires USB I/O which is done easier from port_probe() callback rather than attach(). Since the USB access functions take port as a parameter, and since the private data is used exclusively by these functions, it can be allocated in port_probe(). Also, all cp210x devices have exactly 1 port per USB iterface, so moving private data from the USB interface to port is trivial.

usb: cp210x: Update to support CP2105 and multiple interface devices This patch updates the cp210x driver to support CP210x multiple interface devices devices from Silicon Labs. The existing driver always sends control requests to interface 0, which is hardcoded in the usb_control_msg function calls. This only allows for single interface devices to be used, and causes a bug when using ports on an interface other than 0 in the multiple interface devices. Here are the changes included in this patch: - Updated the device list to contain the Silicon Labs factory default VID/PID for multiple interface CP210x devices - Created a cp210x_port_private struct created for each port on startup, this struct holds the interface number - Added a cp210x_release function to clean up the cp210x_port_private memory created on startup - Modified usb_get_config and usb_set_config to get a pointer to the cp210x_port_private struct, and use the interface number there in the usb_control_message wIndex param Signed-off-by: Preston Fick <preston.fick@silabs.com> Cc: stable <stable@vger.kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

USB: cp210x: work around cp2108 GET_LINE_CTL bug Add helper to access line-control register in order to work around a cp2108 GET_LINE_CTL bug. cp2108 GET_LINE_CTL returns the 16-bit value with the 2 bytes swapped. However, SET_LINE_CTL functions properly. When the driver tries to modify the register, it reads it, modifies some bits and writes back. Because the read bytes were swapped, this often results in an invalid value to be written. In turn, this causes cp2108 respond with a stall. The stall sometimes doesn't clear properly and cp2108 starts responding to following valid commands also with stalls, effectively failing.

USB: cp210x: fix CP2104 baudrate usage This fix changes the way baudrates are set on the CP210x devices from Silicon Labs. The CP2101/2/3 will respond to both a GET/SET_BAUDDIV command, and GET/SET_BAUDRATE command, while CP2104 and higher devices only respond to GET/SET_BAUDRATE. The current cp210x.ko driver in kernel version 3.2.0 only implements the GET/SET_BAUDDIV command. This patch implements the two new codes for the GET/SET_BAUDRATE commands. Then there is a change in the way that the baudrate is assigned or retrieved. This is done according to the CP210x USB specification in AN571. This document can be found here: http://www.silabs.com/pages/DownloadDoc.aspx?FILEURL=Support%20Documents/TechnicalDocs/AN571.pdf&src=DocumentationWebPart Sections 5.3/5.4 describe the USB packets for the old baudrate method. Sections 5.5/5.6 describe the USB packets for the new method. This patch also implements the new request scheme, and eliminates the unnecessary baudrate calculations since it uses the "actual baudrate" method. This patch solves the problem reported for the CP2104 in bug 42586, and also keeps support for all other devices (CP2101/2/3). This patchfile is also attached to the bug report on bugzilla.kernel.org. This patch has been developed and test on the 3.2.0 mainline kernel version under Ubuntu 10.11.

USB: cp210x: add tx_empty() Added tx_empty callback needed for generic wait-until-sent support. Without this function, when the port is closed usbserial can't know that there are still data in the chip's transmit FIFO. The chip gets disabled and untransmitted data lost. When the actual byte count is reported by tx-empty the close can be delayed until all data are sent.

USB: cp210x: flush device queues at close Flush all device queues at close in order to work around a cp2108 Tx queue bug. Occasionally, writing data and immediately closing the port makes cp2108 stop responding. The device has to be unplugged to clear the error. The failure is induced by shutting down the device while its Tx queue still has unsent data. This condition is avoided by issuing PURGE command from the close() callback. This change is applied to all cp210x devices. Clearing internal queues on close is generally good.

USB: cp210x: work around cp2108 GET_LINE_CTL bug Add helper to access line-control register in order to work around a cp2108 GET_LINE_CTL bug. cp2108 GET_LINE_CTL returns the 16-bit value with the 2 bytes swapped. However, SET_LINE_CTL functions properly. When the driver tries to modify the register, it reads it, modifies some bits and writes back. Because the read bytes were swapped, this often results in an invalid value to be written. In turn, this causes cp2108 respond with a stall. The stall sometimes doesn't clear properly and cp2108 starts responding to following valid commands also with stalls, effectively failing.

USB: cp210x: work around cp2108 GET_LINE_CTL bug Add helper to access line-control register in order to work around a cp2108 GET_LINE_CTL bug. cp2108 GET_LINE_CTL returns the 16-bit value with the 2 bytes swapped. However, SET_LINE_CTL functions properly. When the driver tries to modify the register, it reads it, modifies some bits and writes back. Because the read bytes were swapped, this often results in an invalid value to be written. In turn, this causes cp2108 respond with a stall. The stall sometimes doesn't clear properly and cp2108 starts responding to following valid commands also with stalls, effectively failing.

USB: Fix cp2101 USB serial device driver termios functions for console use This is really a follow up to the modifications Alan Cox made for commit 95da310e66ee8090119596c70ca8432e57f9a97f to pass a tty_struct to various interface functions, which broke the serial configuration (termios) functions when the device is being used as a console. These changes restore the configuration to proper functioning both as a tty and as a console. As Alan notes in that commit, these changes will need to be tweaked when we have a proper console abstraction.

Unfortunately when you consider hangup events, hangup/parallel reopen or even worse hangup followed by parallel close events the tty->port and port->tty pointers are not guaranteed to be the same as port->tty is the active tty while tty->port is the port the tty may or may not still be attached to. So rework the entire API to pass the tty struct. For console cases we need to pass both for now. This shows up multiple drivers that immediately crash with USB console some of which have been fixed in the process.

USB: cp210x: work around cp2108 GET_LINE_CTL bug Add helper to access line-control register in order to work around a cp2108 GET_LINE_CTL bug. cp2108 GET_LINE_CTL returns the 16-bit value with the 2 bytes swapped. However, SET_LINE_CTL functions properly. When the driver tries to modify the register, it reads it, modifies some bits and writes back. Because the read bytes were swapped, this often results in an invalid value to be written. In turn, this causes cp2108 respond with a stall. The stall sometimes doesn't clear properly and cp2108 starts responding to following valid commands also with stalls, effectively failing.

usb_serial: API all change USB serial likes to use port->tty back pointers for the real work it does and to do so without any actual locking. Unfortunately when you consider hangup events, hangup/parallel reopen or even worse hangup followed by parallel close events the tty->port and port->tty pointers are not guaranteed to be the same as port->tty is the active tty while tty->port is the port the tty may or may not still be attached to. So rework the entire API to pass the tty struct. For console cases we need to pass both for now. This shows up multiple drivers that immediately crash with USB console some of which have been fixed in the process. Longer term we need a proper tty as console abstraction Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

USB: cp210x: relocate private data from USB interface to port This change is preparation for implementing a cp2108 bug workaround. The workaround requires storing some private data. Right now the data is attached to the USB interface and allocated in the attach() callback. The bug detection requires USB I/O which is done easier from port_probe() callback rather than attach(). Since the USB access functions take port as a parameter, and since the private data is used exclusively by these functions, it can be allocated in port_probe(). Also, all cp210x devices have exactly 1 port per USB iterface, so moving private data from the USB interface to port is trivial.

However, SET_LINE_CTL functions properly. When the driver tries to modify the register, it reads it, modifies some bits and writes back. Because the read bytes were swapped, this often results in an invalid value to be written. In turn, this causes cp2108 respond with a stall. The stall sometimes doesn't clear properly and cp2108 starts responding to following valid commands also with stalls, effectively failing.

USB: serial: rework usb_serial_register/deregister_drivers() This reworks the usb_serial_register_drivers() and usb_serial_deregister_drivers() to not need a pointer to a struct usb_driver anymore. The usb_driver structure is now created dynamically and registered and unregistered as needed. This saves lines of code in each usb-serial driver. All in-kernel users of these functions were also fixed up at this time. The pl2303 driver was tested that everything worked properly. Thanks for the idea to do this from Alan Stern.

module_usb_serial_driver(serial_drivers, id_table);
Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
