NTP server sync issue

Hi , On my target the date time in linux is not getting updated as per The NTP server date. The update of date and sync between NTP server and NTP client on the target happens Correctly when the NTP server is made up and then the ntp client is made up. If I make the NTP server down and then

I have a hang problem on my board based on MPC8377EWLAN, here is how i ran into problem. We are using u-boot to load the kernel, rootfs and device tree.  The kernel parameters have been set root=/dev/ram rw rootfstype=ext2 ramdisk_size=131322 console=ttyS0,115200 but I load the rootfs image g

[RFCv2 11/14] irq_domain: Replace irq_alloc_host() with revmap-specific initializers

Each revmap type has different arguments for setting up the revmap. This patch splits up the generator functions so that each revmap type can do its own setup and the user doesn't need to keep track of how each revmap type handles the arguments. This patch also adds a host_data argument to the gen

[RFCv2 12/14] irq_domain: Add support for base irq and hwirq in legacy mappings

Add support for a legacy mapping where irq = (hwirq - first_hwirq + first_irq) so that a controller driver can allocate a fixed range of irq_descs and use a simple calculation to translate back and forth between linux and hw irq numbers. This is needed to use an irq_domain with many of the ARM int

[RFCv2 14/14] irq_domain: Remove irq_domain_add_simple()

irq_domain_add_simple() was a stop-gap measure until complete irq_domain support was complete. This patch removes the irq_domain_add_simple() interface. v2: Updated to pass in host_data pointer on irq_domain allocation. Signed-off-by: Grant Likely --- arch/arm/mach-imx/mach-imx6q.c |3

[RFCv2 13/14] irq_domain: Remove 'new' irq_domain in favour of the ppc one

This patch removes the simplistic implementation of irq_domains and enables the powerpc infrastructure for all irq_domain users. The powerpc infrastructure includes support for complex mappings between Linux and hardware irq numbers, and can manage allocation of irq_descs. This patch also convert

[RFCv2 10/14] irq_domain: Remove references to old irq_host names

No functional changes. Replaces non-exported references to 'host' with domain. Does not change any symbol names referenced by other .c files. Signed-off-by: Grant Likely Cc: Benjamin Herrenschmidt --- kernel/irq/irqdomain.c | 219 1 files chang

[RFCv2 08/14] irq_domain: Move irq_domain code from powerpc to kernel/irq

This patch only moves the code. It doesn't make any changes, and the code is still only compiled for powerpc. Follow-on patches will generalize the code for other architectures. Signed-off-by: Grant Likely Cc: Benjamin Herrenschmidt --- arch/powerpc/Kconfig |1 + arch/powerpc/in

[RFCv2 09/14] irqdomain: remove NO_IRQ from irq domain code

zero always means no irq when using irq domains. Get rid of the NO_IRQ references. Signed-off-by: Grant Likely Cc: Benjamin Herrenschmidt --- kernel/irq/irqdomain.c | 38 +++--- 1 files changed, 19 insertions(+), 19 deletions(-) diff --git a/kernel/irq/irqdom

[RFCv2 06/14] irq_domain/powerpc: eliminate irq_map; use irq_alloc_desc() instead

This patch drops the powerpc-specific irq_map table and replaces it with directly using the irq_alloc_desc()/irq_free_desc() interfaces for allocating and freeing irq_desc structures. This patch is a preparation step for generalizing the powerpc-specific virq infrastructure to become irq_domains.

[RFCv2 03/14] irq_domain: Make irq_domain structure match powerpc's irq_host

Part of the series to unify the irq remapping mechanisms in the kernel. A follow up patch will copy the powerpc implementation into kernel/irq/irqdomain.c, which will be a lot easier if the structures are identical. Where they differ, I've chose to use the powerpc names since there is a lot more
