2012-12-13microblaze: Fix intc_enable_or_unmask functionMichal Simek-1/+2
Intc_enable_or_unmask() is called at the last stage of handle_level_irq(). This function enables the irq first (Write INTC.SIE) and clear ISR next (Write INTC.IAR). This would create problems that processor will get into a new interrupt as soon as SIE is written because the previous level interrupt has been captured by INTC. If the description bring some puzzles, here is the details of how interrupt is handled for MicroBlaze after Interrupt signal is detected: 1. disable INTC (INTC.CIE = 1) 2. Acknowledge INTC (INTC.IAR = 1) 3. gets into interrupt source's handler, for example, timer's handler 4. Timer is interrupt handler acknowledge Timer Interrupt Status (Timer.TCSR0[23] = 1), and return 5. Enable INTC (INTC.SIE = 1) 6. Acknowledge INTC (INTC.IAR = 1) INTC continue to capture source inputs even if INTC is disabled (INTC.IER == 1). So between the gap of step 2 and step 3, the level interrupt from source makes INTC captures a new interrupt and thus the INTC.ISR = 1 during step 3, 4, and 5. When INTC is enabled in step 5, INTC's interrupt output will go high immediately. In summary, the driver should issue step 6 before step 5. Signed-off-by: Michal Simek <>

2012-12-13microblaze: uaccess.h: Fix timerfd syscallMichal Simek-2/+1
__pu_val must be volatile to ensure that the value is not lost. It was causing the problem with timerfd syscall where using inline asm at the end of function call doesn't save u64 bit value to the stack. In comparison both cases you can find out this fragment where you can see the first part which is saved u64 value to stack and then using it in __put_user_asm_8 macro. Origin broken implementation misses the first two swi instructions. swi r22, r1, 28 /* missing without volatile */ swi r23, r1, 32 ... addik r4, r1, 28 lwi r3, r4, 0 swi r3, r25, 0 lwi r3, r4, 4 swi r3, r25, 4 addk r3, r0, r0 NOTE: Moving __put_val initialization after declaration has not impact on this bug. It is just coding style issue. Signed-off-by: Michal Simek <>

2012-12-12MN10300: fix debug polling in ttySM driverMark Salter-12/+23
The debug polling interface for the SoC serial ports did not work in the case where the serial ports were not also used as a console. In that case, the uart driver startup function will not be called so tx and rx would not be enabled in the hardware control register. Also, vdma interrupts would not be enabled which the poll_get_char function relied on. This patch makes sure that the rx and tx enables are set as a consequence of the uart set_termios call which is the only initialization done for the debug polling interface. Also, the poll_get_char now handles the case where vdma interrupts are not enabled. Signed-off-by: Mark Salter <> Signed-off-by: David Howells <>

2012-12-12MN10300: fix SMP synchronization between txdma and serial driverMark Salter-48/+90
The SoC serial port driver uses a high priority interrupt to handle tx of characters in the tx ring buffer. The driver needs to disable/enable this IRQ from outside of irq context. The original code to do this is not foolproof on SMP machines because the IRQ running on one core could still access the serial port for a short time after the driver running on another core disables the interrupt. This patch adds a flag to tell the IRQ handler that the driver wants to disable the interrupt. After seeing the flag, the IRQ handler will immediately disable the interrupt and exit. After setting the flag, the driver will wait for interrupt to be disabled by the IRQ handler. Signed-off-by: Mark Salter <> Signed-off-by: David Howells <>
2012-12-12MN10300: fix serial port vdma irq setup for SMPMark Salter-4/+30
The builtin SoC serial ports have no FIFOs and use a virtual DMA mechanism based on high priority IRQs to avoid overruns. These high priority interrupts are pinned to cpu#0 on SMP systems. This patch fixes a problem with SMP where the set_intr_level() interface is used to set the priority for these IRQs. The set_intr_level() function sets priority on the local cpu but on SMP systems, this code may be run on some other cpu than the one handling the interrupts. Instead of setting interrupt level explicitly, this patch uses a special irq_chip for these interrupts so that the mask/unmask methods can set the interrupt level implicitly.

2012-12-12MN10300: cleanup IRQ affinity settingMark Salter-52/+17
The irq_set_affinity handler for the mn10300 cpu pic had some hard-coded IRQs which were not to be migrated from one cpu to another. This patch cleans those up by using a combination of IRQF_NOBALANCING and specialized irq chips with no irq_set_affinity handler. This maintains the previous behavior by using generic IRQ interfaces rather than hard coding IRQ numbers in the default irq_set_affinity handler.

Pull ARM OMAP serial updates from Russell King: "This series is a major reworking of the OMAP serial driver code fixing various bugs in the hardware-assisted flow control, extending up into serial_core for a couple of issues. These fixes have been done as a set of progressive changes and transformations in the hope that no new bugs will be introduced by this series. The problems are many-fold, from the driver not being informed about updated settings, to the driver not knowing what the intentions of the upper layers are. The first four patches tackle the serial_core layer, allowing it to provide the necessary information to drivers, and the remaining patches allow the OMAP serial driver to take advantage of this. This brings hardware assisted RTS/CTS and XON/OFF flow control into a useful state. These patches have been in linux-next for most of the last cycle; indeed they predate the previous merge window.

Allowing this required the identification and fixing of latent CPU#0 assumptions (such as CPU#0 initializations, etc.) in the x86 architecture code, plus the identification of barriers to BSP-offlining, such as active PIC interrupts which can only be serviced on the BSP. It's behind a default-off option, and there's a debug option that allows the automatic testing of this feature. The motivation of this feature is to allow and prepare for true CPU-hotplug hardware support: recent changes to MCE support enable us to detect a deteriorating but not yet hard-failing L1/L2 cache on a CPU that could be soft-unplugged - or a failing L3 cache on a multi-socket system.
