2011-02-17tty: now phase out the ioctl file pointer for goodAlan Cox41-78/+66

2011-02-17tiocmget: kill off the passing of the struct fileAlan Cox69-101/+98
We don't actually need this and it causes problems for internal use of this functionality. Currently there is a single use of the FILE * pointer. That is the serial core which uses it to check tty_hung_up_p. However if that is true then IO_ERROR is also already set so the check may be removed.

2011-02-17tty: serial: altera_uart: Use port->regshift to store bus shiftTobias Klauser1-7/+7
Use the regshift member of struct uart_port to store the address stride from platform data. This way we can save one dereference per call of altera_uart_readl and altera_uart_writel. This also allows us to use the driver without platform data, which is needed for device tree support in the Nios2 port.

2011-02-17serial: change the divisor latch only when prescalar actually changedYin Kangkai1-12/+20
In 8250.c original ns16550 autoconfig code, we change the divisor latch when we goto to high speed mode, we're assuming the previous speed is legacy. This some times is not true. For example in a system with both CONFIG_SERIAL_8250 and CONFIG_SERIAL_8250_PNP set, in this case, the code (autoconfig) will be called twice, one in serial8250_init/probe() and the other is from serial_pnp_probe. When serial_pnp_probe calls the autoconfig for NS16550A, it's already in high speed mode, change the divisor latch (quot << 3) in this case will make the UART console garbled.

Otherwise it is still the old 1843200 and that will bring issues.

2011-02-17tty,vcs removing con_buf/conf_buf_mtxJiri Olsa3-66/+52
seems there's no longer need for using con_buf/conf_buf_mtx as vcs_read/vcs_write buffer for user's data. The do_con_write function, that was the other user of this, is currently using its own kmalloc-ed buffer. Not sure when this got changed, as I was able to find this code in 2.6.9, but it's already gone as far as current git history goes - 2.6.12-rc2. AFAICS there's a behaviour change with the current change. The lseek is not completely mutually exclusive with the vcs_read/vcs_write - the file->f_pos might get updated via lseek callback during the vcs_read/vcs_write processing. I tried to find out if the prefered behaviour is to keep this in sync within read/write/lseek functions, but I did not find any pattern on different places. I guess if user end up calling write/lseek from different threads she should know what she's doing. If needed we could use dedicated fd mutex/buffer.

2011-02-04hvc_dcc: Simplify assembly for v6 and v7 ARMStephen Boyd1-24/+0
The inline assembly differences for v6 vs. v7 in the hvc_dcc driver are purely optimizations. On a v7 processor, an mrc with the pc sets the condition codes to the 28-31 bits of the register being read. It just so happens that the TX/RX full bits the DCC driver is testing for are high enough in the register to be put into the condition codes. On a v6 processor, this "feature" isn't implemented and thus we have to do the usual read, mask, test operations to check for TX/RX full. Since we already test the RX/TX full bits before calling __dcc_getchar() and __dcc_putchar() we don't actually need to do anything special for v7 over v6. The only difference is in hvc_dcc_get_chars(). We would test RX full, poll RX full, and then read a character from the buffer, whereas now we will test RX full, read a character from the buffer, and then test RX full again for the second iteration of the loop. It doesn't seem possible for the buffer to go from full to empty between testing the RX full and reading a character. Therefore, replace the v7 versions with the v6 versions and everything works the same.

2011-02-04hvc_dcc: Fix bad code generation by marking assembly volatileStephen Boyd1-6/+5
Without marking the asm __dcc_getstatus() volatile my compiler decides it can cache the value of __ret in a register and then check the value of it continually in hvc_dcc_put_chars() (I had to replace get_wait/put_wait with 1 and fixup the branch otherwise my disassembler barfed on __dcc_(get|put)char). 00000000 <hvc_dcc_put_chars>: 0: ee103e11 mrc 14, 0, r3, cr0, cr1, {0} 4: e3a0c000 mov ip, #0 ; 0x0 8: e2033202 and r3, r3, #536870912 ; 0x20000000 c: ea000006 b 2c <hvc_dcc_put_chars+0x2c> 10: e3530000 cmp r3, #0 ; 0x0 14: 1afffffd bne 10 <hvc_dcc_put_chars+0x10> 18: e7d1000c ldrb r0, [r1, ip] 1c: ee10fe11 mrc 14, 0, pc, cr0, cr1, {0} 20: 2afffffd bcs 1c <hvc_dcc_put_chars+0x1c> 24: ee000e15 mcr 14, 0, r0, cr0, cr5, {0} 28: e28cc001 add ip, ip, #1 ; 0x1 2c: e15c0002 cmp ip, r2 30: bafffff6 blt 10 <hvc_dcc_put_chars+0x10> 34: e1a00002 mov r0, r2 38: e12fff1e bx lr As you can see, the value of the mrc is checked against DCC_STATUS_TX (bit 29) and then stored in r3 for later use. Marking the asm volatile produces the following: 00000000 <hvc_dcc_put_chars>: 0: e3a03000 mov r3, #0 ; 0x0 4: ea000007 b 28 <hvc_dcc_put_chars+0x28> 8: ee100e11 mrc 14, 0, r0, cr0, cr1, {0} c: e3100202 tst r0, #536870912 ; 0x20000000 10: 1afffffc bne 8 <hvc_dcc_put_chars+0x8> 14: e7d10003 ldrb r0, [r1, r3] 18: ee10fe11 mrc 14, 0, pc, cr0, cr1, {0} 1c: 2afffffd bcs 18 <hvc_dcc_put_chars+0x18> 20: ee000e15 mcr 14, 0, r0, cr0, cr5, {0} 24: e2833001 add r3, r3, #1 ; 0x1 28: e1530002 cmp r3, r2 2c: bafffff5 blt 8 <hvc_dcc_put_chars+0x8> 30: e1a00002 mov r0, r2 34: e12fff1e bx lr which looks better and actually works. Mark all the inline assembly in this file as volatile since we don't want the compiler to optimize away these statements or move them around in any way.

2011-02-04serial-core: reset the console speed on resumeYin Kangkai1-3/+3
On some platforms, we need to restore the console speed on resume even it was not suspended (no_console_suspend), and on others we don't have to do that. So don't care about the "console_suspend_enabled" and unconditionally reset the console speed if it is a console. This is actually a redo of ba15ab0 (Set proper console speed on resume if console suspend is disabled) from Deepak Saxena. I also tried to investigate more to find out if this change will break others, here is what I've found out: commit 891b9dd10764352926e1e107756aa229dfa2c210 Author: Jason Wang <jason77.wang@gmail.com> serial-core: restore termios settings when resume console ports commit ca2e71aa8cfb0056ce720f3fd53f59f5fac4a3e1 Author: Jason Wang <jason77.wang@gmail.com> serial-core: skip call set_termios/console_start when no_console_suspend commit 4547be7809a3b775ce750ec7f8b5748954741523 Author: Stanislav Brabec <sbrabec@suse.cz> serial-core: resume serial hardware with no_console_suspend commit ba15ab0e8de0d4439a91342ad52d55ca9e313f3d Author: Deepak Saxena <dsaxena@laptop.org> Set proper console speed on resume if console suspend is disabled from ba15ab0, we learned that, even if the console suspend is disabled (when no_console_suspend is set), we may still need to "reset the port to the state it was in before we suspended." Then with 4547be7, this piece of code is removed. And then Jason Wang added that back in ca2e71a and 891b9dd, to fix some breakage on OMAP3EVM platform. From ca2e71a we learned that the "set_termios" things is actually needed by both console is suspended and not suspended. That's why I removed the console_suspended_enabled condition, and only call console_start() when we actually suspeneded it. I also noticed in this thread: http://marc.info/?t=129079257100004&r=1&w=2, which talked about on some platforms, UART HW will be cut power whether or not we set no_console_suspend, and then on resume it does not work quite well. I have a similar HW, and this patch fixed this issue, don't know if this patch also works on their platforms. [Update: Stanislav tested this patch on Zaurus and reported it improves the situation.

2011-02-04serial: omap-serial: Enable the UART wake-up bits alwaysJarkko Nikula1-3/+3
OMAP can do also dynamic idling so wake-up enable register should be set also while system is running. If UART_OMAP_WER is not set, then for instance the RX activity cannot wake up the UART port that is sleeping. This RX wake-up feature was working when the 8250 driver was used instead of omap-serial. Reason for this is that the 8250 doesn't set the UART_OMAP_WER and then arch/arm/mach-omap2/pm34xx.c ends up saving and restoring the reset default which is the same than value OMAP_UART_WER_MOD_WKUP here. Fix this by moving the conditional UART_OMAP_WER write from serial_omap_pm into serial_omap_startup where wake-up bits are set unconditionally.

2011-02-01ARM: smp_on_up: allow non-ARM SMP processorsRussell King1-12/+10
Allow non-ARM SMP processors to use the SMP_ON_UP feature. CPUs supporting SMP must have the new CPU ID format, so check for this first. Then check for ARM11MPCore, which fails the MPIDR check. Lastly check the MPIDR reports multiprocessing extensions and that the CPU is part of a multiprocessing system.

2011-01-31ARM: io: ensure inb/outb() et.al. are properly ordered on ARMv6+Russell King1-16/+17
Ensure that the ISA/PCI IO space accessors are properly ordered on ARMv6+ architectures. These should always be ordered with respect to all other accesses. This also fixes __iormb() and __iowmb() not being visible to ioread/ iowrite if a platform defines its own MMIO accessors. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2011-01-31ARM: initrd: disable initrd if passed address overlaps reserved regionRussell King1-0/+6
Disable the initrd if the passed address already overlaps the reserved region. This avoids oopses on Netwinders when NeTTrom tells the kernel that an initrd is located at mem+4MB, but this overlaps the BSS, resulting in the kernels in-use BSS being freed. This should be applied to v2.6.37-stable. Cc: <stable@kernel.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
