2010-02-16serial: 8250: add serial transmitter fully empty testDick Hollenbeck1-3/+4
When controlling an industrial radio modem it can be necessary to manipulate the handshake lines in order to control the radio modem's transmitter, from userspace. The transmitter should not be turned off before all characters have been transmitted. serial8250_tx_empty() was reporting that all characters were transmitted before they actually were. === Discovered in parallel with more testing and analysis by Kees Schoenmakers as follows: I ran into an NetMos 9835 serial pci board which behaves a little different than the standard. This type of expansion board is very common. "Standard" 8250 compatible devices clear the 'UART_LST_TEMT" bit together with the "UART_LSR_THRE" bit when writing data to the device. The NetMos device does it slightly different I believe that the TEMT bit is coupled to the shift register. The problem is that after writing data to the device and very quickly after that one does call serial8250_tx_empty, it returns the wrong information. My patch makes the test more robust (and solves the problem) and it does not affect the already correct devices. Alan: We may yet need to quirk this but now we know which chips we have a way to do that should we find this breaks some other 8250 clone with dodgy THRE.

2010-01-20serial-core: resume serial hardware with no_console_suspendStanislav Brabec1-55/+33
Perform a tricky suspend/resume even with no_console_suspend. With no_console_suspend, kernel skips serial port suspend/resume and the serial hardware may remain in undefined state after resume. It actually happens on devices that don't have BIOS that handle serial initialization. It makes impossible to use serial console after resume. Devices affected by this problem include: Sharp Zaurus devices Several PXA based ARM embedded boards The patch does: - Save the hardware state - Perform buffer flush in time of its suspend call - Tell the driver that port is suspended - But still accept new data - And keep console hardware in state that allows to send them It allows to capture late console messages without breaking console after resume. This is just a resend of a patch discussed in these threads, as the patch was not yet applied. "Possible suspend/resume regression in .32-rc?"

2010-01-15serial/pmac_zilog: Workaround problem due to interrupt on closed portBenjamin Herrenschmidt1-0/+11
It seems that in qemu, we can see an interrupt in R3 despite the fact that it's masked in W1. The chip doesn't actually issue an interrupt, but we can "see" it when taking an interrupt for the other channel. This may be a qemu bug ... or not, so let's be safe and avoid calling into the UART layer when that happens which woulc cause a crash.

2009-12-11Serial: Do not read IIR in serial8250_start_tx when UART_BUG_TXENIan Jackson1-5/+3
Do not read IIR in serial8250_start_tx when UART_BUG_TXEN Reading the IIR clears some oustanding interrupts so it is not safe. Instead, simply transmit immediately if the buffer is empty without regard to IIR.

2009-12-11Serial: pxa: work around Errata #75Uwe Kleine-König1-2/+11
Intel(R) PXA27x Processor Family Specification Update (Nov 2005) says: E75. UART: Baud rate may not be programmed correctly on back-to-back writes. Problem: When programming the Divisor Latch registers, Low and High (DLL and DLH), with back-to-back writes, the second register write may not take effect. The result is an incorrect baud rate. Workaround: After programming the first Divisor Latch register, read and verify it before programming the second Divisor Latch register. This was hit when changing the baud rate from 115200 to 9600 while receiving characters at 9600 Bd. And fixed indention of some comments nearby.

2009-12-11firmware_class: make request_firmware_nowait more usefulJohannes Berg1-3/+5
Unfortunately, one cannot hold on to the struct firmware that request_firmware_nowait() hands off, which is needed in some cases. Allow this by requiring the callback to free it (via release_firmware). Additionally, give it a gfp_t parameter -- all the current users call it from a GFP_KERNEL context so the GFP_ATOMIC isn't necessary. This also marks an API break which is useful in a sense, although that is obviously not the primary purpose of this change.
