[PATCH V2 0/2] [BUGFIX] virtio/console: Fix two bugs of splice_write

Hi, This patch set fixes two bugs of splice_write in the virtio-console driver. [BUG1] Although pipe->nrbufs is empty, the driver tries to do splice_write. => This induces oops in sg_init_table(). [BUG2] No lock for competition of splice_write. => This induces oops in

[PATCH V2 2/2] [BUGFIX] virtio/console: Add pipe_lock/unlock for splice_write

Add pipe_lock/unlock for splice_write to avoid oops by following competition: (1) An application gets fds of a trace buffer, virtio-serial, pipe. (2) The application does fork() (3) The processes execute splice_read(trace buffer) and splice_write(virtio-serial) via same pipe.

[PATCH V2 1/2] [BUGFIX] virtio/console: Quit from splice_write if pipe->nrbufs is 0

Quit from splice_write if pipe->nrbufs is 0 for avoiding oops in virtio-serial. When an application was doing splice from a kernel buffer to virtio-serial on a guest, the application received signal(SIGINT). This situation will normally happen, but the kernel executed a kernel panic by oops as

[PATCH v2 0/5] iio: mxs-lradc: add support to optional divider_by_two

Greetings, This is v2 of the patchset that adds support to the optional divider_by_two of LRADC channels. Changes in v2: - Fix the sample mask passed by the touchscreen driver to the input subsytem, to be 12 bits. - Move the reference voltages to the Device Tree. - Rebased to avoid conflict

[PATCH v2 3/5] iio: mxs-lradc: add scale attribute to channels

Some LRADC channels have fixed pre-dividers and all have an optional divider by two which allows a maximum input voltage of VDDIO - 50mV. This patch - adds the scaling info flag to all channels - grabs the max reference voltage per channel from DT (where the fixed pre-dividers apply) -

[PATCH v2 1/5] iio: mxs-lradc: change the realbits to 12

The LRADC virtual channels have an 18 bit field to store the sum of up to 2^5 accumulated samples. The read_raw function however only operates over a single sample (12 bit resolution). In order to use this field for scaling operations, we need it to be the exact resolution value of the LRADC.

[PATCH 19/21] x86, numa: Save nid when reserve memory into memblock.reserved[].

We have introduced numa_sync_memblock_nid to synchronize nid info in memblock.reserved[] and numa_meminfo. But memblock_reserve() always reserve memory with MAX_NUMNODES, even after numa_meminfo has been initialized. So this patch improves memblock_reserve() to reserve memory with correct nid.

There is no flag in memblock to describe what type the memory is. Sometimes, we may use memblock to reserve some memory for special usage. And we want to know what kind of memory it is. So we need a way to differentiate memory for different usage. In hotplug environment, we want to reserve

[PATCH 16/21] x86, memblock, mem-hotplug: Free hotpluggable memory reserved by memblock.

We reserved hotpluggable memory in memblock at early time. And when memory initialization is done, we have to free it to buddy system. This patch free memory reserved by memblock with flag MEMBLK_HOTPLUGGABLE. Signed-off-by: Tang Chen Reviewed-by: Wanpeng Li --- include/linux/memblock.h |

[PATCH 13/21] x86, acpi: Try to find SRAT in firmware earlier.

This patch introduce early_acpi_firmware_srat() to find the phys addr of SRAT provided by firmware. And call it in reserve_hotpluggable_memory(). Since we have initialized acpi_gbl_root_table_list earlier, and store all the tables' phys addrs and signatures in it, it is easy to find the SRAT.

[PATCH 11/21] x86: get pg_data_t's memory from other node

From: Yasuaki Ishimatsu If system can create movable node which all memory of the node is allocated as ZONE_MOVABLE, setup_node_data() cannot allocate memory for the node's pg_data_t. So, use memblock_alloc_try_nid() instead of memblock_alloc_nid() to retry when the first allocation fails.

[PATCH 14/21] x86, acpi, numa: Reserve hotpluggable memory at early time.

As mentioned before, in order to prevent the kernel to use hotpluggable memory, we want to reserve hotpluggable memory in memblock at early time. As the previous two patches are able to find SRAT in initrd file or fireware, this patch does the following: 1. Introduces

Re: [PATCH] videobuf2-dma-sg: Minimize the number of dma segments

Hello Marek I have prepared a new set of patches, please take a look to them. The series implements the coherent allocation, segments compaction and use of sg_table, it does not implement the dma_map/dma_unmap/dma_sync, I rather work on that one when you are back. Thanks for your help On Thu,

[PATCH 08/21] x86, acpi: Also initialize signature and length when parsing root table.

Besides the phys addr of the acpi tables, it will be very convenient if we also have the signature of each table in acpi_gbl_root_table_list at early time. We can find SRAT easily by comparing the signature. This patch alse record signature and some other info in acpi_gbl_root_table_list at early

[PATCH 17/21] page_alloc, mem-hotplug: Improve movablecore to {en|dis}able using SRAT.

The Hot-Pluggable fired in SRAT specifies which memory is hotpluggable. As we mentioned before, if hotpluggable memory is used by the kernel, it cannot be hot-removed. So memory hotplug users may want to set all hotpluggable memory in ZONE_MOVABLE so that the kernel won't use it. Memory hotplug

[PATCH 05/21] acpi: Introduce acpi_invalid_table() to check if a table is invalid.

In acpi_initrd_override(), it checks several things to ensure the table it found is valid. In later patches, we need to do these check somewhere else. So this patch introduces a common function acpi_invalid_table() to do all these checks, and reuse it in different places. The function will be used

[PATCH 09/21] x86: Make get_ramdisk_{image|size}() global.

In the following patches, we need to call get_ramdisk_{image|size}() to get initrd file's address and size. So make these two functions global. Signed-off-by: Tang Chen --- arch/x86/include/asm/setup.h |3 +++ arch/x86/kernel/setup.c |4 ++-- 2 files changed, 5 insertions(+), 2

[PATCH 15/21] x86, acpi, numa: Don't reserve memory on nodes the kernel resides in.

If all the memory ranges in SRAT are hotpluggable, we should not reserve all of them in memblock. Otherwise the kernel won't have enough memory to boot. And also, memblock will reserve some memory at early time, such initrd file, kernel code and data segments, and so on. We cannot avoid these

[PATCH 10/21] earlycpio.c: Fix the confusing comment of find_cpio_data().

The comments of find_cpio_data() says: * @offset: When a matching file is found, this is the offset to the * beginning of the cpio. .. But according to the code, dptr = PTR_ALIGN(p + ch[C_NAMESIZE], 4); nptr = PTR_ALIGN(dptr + ch[C_FILESIZE], 4); *offset =
