* zs: move to the serial subsystemMaciej W. Rozycki2007-07-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | This is a reimplementation of the zs driver for the serial subsystem. Any resemblance to the old driver is purely coincidential. ;-) I do hope I got the handling of modem lines right -- better do not tackle me about the issue unless you feel too good... Any users of the old driver: please note the numbers of the serial lines have now been swapped, i.e. ttyS0 <-> ttyS1 and ttyS2 <-> ttyS3. It has to do with the modem lines mentioned above; basically the port A in a given chip has to be initialised before the port B if you want to use the latter as the serial console (which is usually the case), as operations on modem lines of the serial line associated with the port B access both ports (see the comment at the top of the driver for the details of wiring used). Please update your scripts. This is also the reason each SCC now requests an IRQ once only (as seen in "/proc/interrupts") -- the handler takes care of both ports at once as the line associated with the port B has to take status update interrupts from both ports (and yet the line of the port A takes its own for itself too). The old driver never got it right... Signed-off-by: Maciej W.

* sb1250-duart.c: SB1250 DUART serial supportMaciej W. Rozycki2007-07-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | This is a driver for the SB1250 DUART, a dual serial port implementation included in the Broadcom family of SOCs descending from the SiByte SB1250 MIPS64 chip multiprocessor. It is a new implementation replacing the old-fashioned driver currently present in the linux-mips.org tree. It supports all the usual features one would expect from a(n asynchronous) serial driver, including modem line control (as far as hardware supports it -- there is edge detection logic missing from the DCD and RI lines and the driver does not implement polling of these lines at the moment), the serial console, BREAK transmission and reception, including the magic SysRq. The receive FIFO threshold is not maintained though. The driver was tested with a SWARM board which uses a BCM1250 SOC (which is dual MIPS64 CMP) and has both ports of the single DUART implemented wired externally. Both were tested. Testing included using the ports as terminal lines at 1200bps (which is the ports minimum), 115200bps and a couple of random speeds inbetween. The modem lines were verified to operate correctly. No testing was performed with a use as a network interface, like with SLIP or PPP. Signed-off-by: Maciej W.

Thus, for each break, the USART sets the RXBRK bit twice. This patch modifies the driver to report the break event to the serial core only once by keeping track of whether a break condition is currently active. The break_active flag is reset as soon as a character is received, so even if we miss the start-of-break interrupt this should do the right thing.

Make early_uart to use early_param, so uart console can be used earlier. Make it to be bootconsole with CON_BOOT flag, so can use console handover feature. and it will switch to corresponding normal serial console automatically. new command line will be: console=uart8250,io,0x3f8,9600n8 console=uart8250,mmio,0xff5e0000,115200n8 or earlycon=uart8250,io,0x3f8,9600n8 earlycon=uart8250,mmio,0xff5e0000,115200n8 it will print in very early stage: Early serial console at I/O port 0x3f8 (options '9600n8') console [uart0] enabled later for console it will print: console handover: boot [uart0] -> real [ttyS0] Signed-off-by: <yinghai.lu@sun.com> Cc: Andi Kleen <ak@suse.de> Cc: Bjorn Helgaas <bjorn.helgaas@hp.com> Cc: Russell King <rmk@arm.linux.org.uk> Cc: Gerd Hoffmann <kraxel@suse.de> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

DTR is normally asserted in uart_startup() when the port is opened. But we don't actually open serial console ports, so assert DTR when the port is added. BTW: earlyprintk and early_uart are hard coded to set DTR/RTS. rmk says The only issue I can think of is the possibility for an attached modem to auto-answer or maybe even auto-dial before the system is ready for it to do so. Might have an undesirable cost implication for some running with such a setup. Apart from that, I can't think of any other side effect of this specific patch.

| | | | | | | | | | | | | | | | | | | | | | The -rt patch triggered a lockdep warning in the amba serial drivers, which never shows up on UP kernels. On SMP systems this would trigger as well. Release the port lock before calling tty_flip_buffer_push() and reacquire it after the call. This matches the code in the 8250 serial driver.

* | [SPARC]: Linux always started with 9600 8N1Jan Engelhardt2007-05-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Linux kernel ignored the PROM's serial settings (115200,n,8,1 in my case). This was because mode_prop remained "ttyX-mode" (expected: "ttya-mode") due to the constness of string literals when used with "char *". Since there is no "ttyX-mode" property in the PROM, Linux always used the default 9600.

* | NS16550A: Restore HS settings in EXCR2 on resumeDavid Woodhouse2007-05-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After a suspend/resume cycle, the UART may have been reset into low-speed mode -- either because it's actually been reset, or because the firmware pokes at the old-style divisor registers. If we detected it as a NS16550A SuperIO chip in the first place and set baud_base to 921600, then we should do so again in the resume path. This patch adds that code to serial8250_resume_port(), and also makes serial8250_resume() actually call serial8250_resume_port() for each port instead of just calling uart_resume_port() directly. And thus fixes serial port operation after suspend/resume. It also fixes a bogus comment where we write the EXCR2 register with a comment saying /* EXCR1 */ Signed-off-by: David Woodhouse <dwmw2@infradead.org> Acked-by: Alan Cox <alan@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* | [SPARC64]: Add hypervisor API negotiation and fix console bugs.David S. Miller2007-05-15
|/ | | | | | | | | | | | | | | | | | | | | | | Hypervisor interfaces need to be negotiated in order to use some API calls reliably. So add a small set of interfaces to request API versions and query current settings. This allows us to fix some bugs in the hypervisor console: 1) If we can negotiate API group CORE of at least major 1 minor 1 we can use con_read and con_write which can improve console performance quite a bit. 2) When we do a console write request, we should hold the spinlock around the whole request, not a byte at a time. What would happen is that it's easy for output from different cpus to get mixed with each other. 3) Use consistent udelay() based polling, udelay(1) each loop with a limit of 1000 polls to handle stuck hypervisor console.
