Instead, copy 'nr_io_queues' into 'vecs' and modify 'vecs' during both MSI-X and MSI setup. This lets us simplify the for-loops that set up MSI-X and MSI, and opens the possibility of using more I/O queues than we have interrupt vectors, should future benchmarking prove that to be a useful feature.

Other than that, we can cut off straightforwardly.

The architecture require this hash page table to be physically contiguous. With KVM on Powerpc currently we use early reservation mechanism for allocating guest hash page table. This implies that we need to reserve a big memory region to ensure we can create large number of guest simultaneously with KVM on Power. Another disadvantage is that the reserved memory is not available to rest of the subsystems and and that implies we limit the total available memory in the host. This patch series switch the guest hash page table allocation to use contiguous memory allocator.

In this scenario, the OS is expected to not monitor for corrected errors (through CMCI/polling). Instead, the firmware notifies the OS on corrected error events through GHES. Linux already has support for GHES. This patch adds support for parsing CMC structure and to disable CMCI/polling if the firmware first flag is set. Further, the list of machine check bank structures at the end of CMC is used to determine which MCA banks function in FF mode, so that we continue to monitor error events on the other banks.

This patch adds the functions kernel_neon_begin() and kernel_neon_end() which take care of the above. It also adds the Kconfig symbol KERNEL_MODE_NEON to enable it.

The tlbie instruction changed between PPC970 and POWER7. On the PPC970, the bit to select large vs. small page is in the instruction, not in the RB register value. This changes the code to use the correct form on PPC970. On POWER7 we were calculating the AVAL (Abbreviated Virtual Address, Lower) field of the RB value incorrectly for 64k pages. This fixes it. Since we now have several cases to handle for the tlbie instruction, this factors out the code to do a sequence of tlbies into a new function, do_tlbies(), and calls that from the various places where the code was doing tlbie instructions inline. It also makes kvmppc_h_bulk_remove() use the same global_invalidates() function for determining whether to do local or global TLB invalidations as is used in other places, for consistency, and also to make sure that kvm->arch.need_tlb_flush gets updated properly.

We have separate ifdefs for each of these definitions, which seems redundant. Introduce lock_acquire_{exclusive,shared,shared_recursive} helpers which will have different definitions based on CONFIG_PROVE_LOCKING.

Both issues are easily fixed by indicating to lockdep that lglock's local locks are not recursive. We shouldn't use the rwlock acquire/release functions here, as lglock doesn't share the same semantics. Instead we can base our lockdep annotations on the lock_acquire_shared (for local lglock) and lock_acquire_exclusive (for global lglock) helpers. I am not proposing new lglock specific helpers as I don't see the point of the existing second level of helpers :) Noticed-by: Oleg Nesterov Signed-off-by: Michel Lespinasse Cc: Lai Jiangshan Cc: "Srivatsa S.

File additions and removals are being reorganized for proper error handling and more dynamic handling for the unified hierarchy, and mixing base and subsys file handling into the same functions gets a bit confusing. This patch moves base file handling out of cgroup_populate/clear_dir() into their users - cgroup_mount(), cgroup_create() and cgroup_destroy_locked(). Note that this changes the behavior of base file removal. If @base_files is %true, cgroup_clear_dir() used to delete files regardless of cftype until there's no files left. Now, only files with matching cfts are removed. As files can only be created by the base or registered cftypes, this shouldn't result in any behavior difference.

Also, rebind_subsystems() users aren't handling file creation errors properly. Let's integrate top_cgroup file handling into rebind_subsystems() so that it's simpler to use and everyone handles file creation errors correctly. * On a successful return, rebind_subsystems() is guaranteed to have created all files of the new subsystems and deleted the ones belonging to the removed subsystems. After a failure, no file is created or removed. * cgroup_remount() no longer needs to make explicit populate/clear calls as it's all handled by rebind_subsystems(), and it gets proper error handling automatically. * cgroup_mount() has been updated such that the root dentry and cgroup are linked before rebind_subsystems(). Also, the init_cred dancing and base file handling are moved right above rebind_subsystems() call and proper error handling for the base files is added. While at it, add a comment explaining what's going on with the cred thing. * cgroup_kill_sb() calls rebind_subsystems() to unbind all subsystems which now implies removing all subsystem files which requires the directory's i_mutex. Grab it. This means that files on the root cgroup are removed earlier - they used to be deleted from generic super_block cleanup from vfs. This doesn't lead to any functional difference and it's cleaner to do the clean up explicitly for all files. Combined with the previous changes, this makes all cgroup file creation errors handled correctly. v2: Added comment on init_cred. v3: Li spotted that cgroup_mount() wasn't freeing tmp_links after base file addition failure. Fix it by adding free_tmp_links error handling label. v4: v3 introduced build bugs which got noticed by Fengguang's awesome kbuild test robot. Fixed, and shame on me.

Wysocki" Date: Sun, 30 Jun 2013 23:48:49 +0200 Subject: [PATCH 0177/9245] ACPI / dock: Rework the handling of notifications The ACPI dock driver uses register_acpi_bus_notifier() which installs a notifier triggered globally for all system notifications. That first of all is inefficient, because the dock driver is only interested in notifications associated with the devices it handles, but it has to handle all system notifies for all devices. Moreover, it does that even if no docking stations are present in the system (CONFIG_ACPI_DOCK set is sufficient for that to happen). Besides, that is inconvenient, because it requires the driver to do extra work for each notification to find the target dock station object. For these reasons, rework the dock driver to install a notify handler individually for each dock station in the system using acpi_install_notify_handler(). This allows the dock station object to be passed directly to the notify handler and makes it possible to simplify the dock driver quite a bit. It also reduces the overhead related to the handling of all system notifies when CONFIG_ACPI_DOCK is set. Signed-off-by: Rafael J.

However, it is not necessary to use a separate notifier chain for that, as it can be simply replaced with a new callback in struct acpi_dock_ops. For this reason, add a new .fixup() callback to struct acpi_dock_ops and make hotplug_dock_devices() execute it for all dock devices with hotplug operations registered. Accordingly, make acpiphp point that callback to the function carrying out the post-dock fixups and do not register a separate dock notifier for each device registering dock operations. Finally, drop the ACPI dock notifier chain that has no more users. Signed-off-by: Rafael J.

This is not really a problem, but the cpuidle init ordering is: the cpuidle init functions (framework and driver) and then the governors. That leads to some weirdness in the cpuidle framework. Namely, cpuidle_register_device() calls cpuidle_enable_device() which fails at the first attempt, because governors have not been registered yet. When a governor is registered, the framework calls cpuidle_enable_device() again which runs __cpuidle_register_device() only then. Of course, for that to work, the cpuidle_enable_device() return value has to be ignored by cpuidle_register_device(). Instead of having this cyclic call graph and relying on a positive side effects of the hackish back and forth cpuidle_enable_device() calls it is better to fix the cpuidle init ordering. To that end, replace the module init code with postcore_initcall() so we have: * cpuidle framework : core_initcall * cpuidle governors : postcore_initcall * cpuidle drivers : device_initcall and remove the corresponding module exit code as it is dead anyway (governors can't be built as modules).

Now, we can safely remove the __cpuidle_register_device() call hack in cpuidle_enable_device() and check if the driver has been registered before enabling it. Then, cpuidle_register_device() can consistently check the cpuidle_enable_device() return value when enabling the device. [rjw: Changelog] Signed-off-by: Daniel Lezcano Signed-off-by: Rafael J.

It is not possible to remove the sysfs entry and create it again. This is not a problem with the current code but future changes will add CPU hotplug support to enable/disable the device, so it will need to remove the sysfs entry like other subsystems do. That won't be possible without this change, because the kobj is a static object which can't be reused for kobj_init_and_add(). Add cpuidle_device_kobj to be allocated dynamically when adding/removing a sysfs entry which is consistent with the other cpuidle's sysfs entries. An added benefit is that the sysfs code is now more self-contained and the includes needed for sysfs can be moved from cpuidle.h directly into sysfs.c so as to reduce the total number of headers dragged along with cpuidle.h.

Saves repeating "(void __force *)__uptr" but it's less clear. Using the output of PTR_RET() to determine the error rather than just testing IS_ERR() is odd. For example, I *assume* __gptr_to_uptr() never returns NULL? Because the __ret would be 0 for the old code. The new version is clearer, IMHO: it would try to get_user() on that address. If you hate this variant, I can just s/PTR_RET/PTR_ERR_OR_ZERO/ instead.

This also allows us to use the SSI driver more flexible so that it can support some use cases like "aplay S16_LE.wav S24_LE.wav" which would call the driver in sequence like: startup()->hw_params(S16_LE)->trigger(START)->tirgger(STOP)-> hw_params(S24_LE)->trigger(START)->tirgger(STOP)->shutdown() If we disable SSIEN in shutdown(), the second hw_params() would bypass the sample bits setting while using symmetric_rate.

This allows dmaengine users like the generic ALSA dmaengine PCM driver to query the capabilities of the driver. The PL330 supports all buswidths and both mem-to-dev as well as dev-to-mem transfers. In theory there is no limit on the number of segments that can be transferred (in practice you'll run out of memory eventually) and the number of bytes per segment is limited by the size of the PL330 program buffer. Due to the nature of the PL330 the maximum number of bytes per segment depends on the burstsize, the driver sets it to the value for a 1-byte burstsize, since it is the smallest.

Therefore the reception of these unwanted packets causes unnecessary processing and power consumption. Packet coalesce feature helps to reduce number of received interrupts to host by buffering these packets in firmware/hardware for some predefined time. Received interrupt will be generated when one of the following events occur. a) Expiration of hardware timer whose expiration time is set to maximum coalescing delay of matching coalesce rule. b) Coalescing buffer in hardware reaches it's limit. c) Packet doesn't match any of the configured coalesce rules. This patch adds set/get configuration support for packet coalesce. User needs to configure following parameters for creating a coalesce rule. a) Maximum coalescing delay b) List of packet patterns which needs to be matched c) Condition for coalescence. pattern 'match' or 'no match' Multiple such rules can be created. This feature needs to be advertised during driver initialization. Drivers are supposed to do required firmware/hardware settings based on user configuration.

A module ref is kept if the specified subsystem is newly bound to the hierarchy. If not, or the operation fails, the refs are dropped. This scatters module ref handling across multiple functions making it difficult to track. It also make the function nasty to use for dynamic subsystem binding which is necessary for the planned unified hierarchy. There's nothing which requires the subsystem modules to be pinned between parse_cgroupfs_options() and rebind_subsystems() in both mount and remount paths. parse_cgroupfs_options() can just parse and rebind_subsystems() can handle pinning the subsystems that it wants to bind, which is a natural part of its task - binding - anyway. Move module ref handling into rebind_subsystems() which makes the code a lot simpler - modules are gotten iff it's gonna be bound and put iff unbound or binding fails. v2: Li pointed out that if a controller module is unloaded between parsing and binding, rebind_subsystems() won't notice the missing controller as it only iterates through existing controllers. Fix it by updating rebind_subsystems() to compare @added_mask to @pinned and fail with -ENOENT if they don't match.

Peter Anvin" Date: Tue, 16 Jul 2013 15:20:14 -0700 Subject: [PATCH 0370/9245] x86, bitops: Change bitops to be native operand size Change the bitops operation to be naturally "long", i.e. 63 bits on the 64-bit kernel. Additional bugs are likely to crop up in the future. We already have bugs which machines with > 16 TiB of memory in a single node, as can happen if memory is interleaved. The x86 bitop operations take a signed index, so using an unsigned type is not an option. Jim Kukunas measured the effect of this patch on kernel size: it adds 2779 bytes to the allyesconfig kernel. Some of that probably could be elided by replacing the inline functions with macros which select the 32-bit type if the index is a 32-bit value, something like: In that case we could also use "Jr" constraints for the 64-bit version. However, this would more than double the amount of code for a relatively small gain. Note that we can't use ilog2() for _BITOPS_LONG_SHIFT, as that causes a recursive header inclusion problem. The change to constant_test_bit() should both generate better code and give correct result for negative bit indicies. As previously written the compiler had to generate extra code to create the proper wrong result for negative values. Signed-off-by: H.

The way this is achieved: - add a int3 trap to the address that will be patched - sync cores - update all but the first byte of the patched range - sync cores - replace the first byte (int3) by the first byte of replacing opcode - sync cores According to http://lkml.indiana.edu/hypermail/linux/kernel/1001.1/01530.html synchronization after replacing "all but first" instructions should not be necessary (on Intel hardware), as the syncing after the subsequent patching of the first byte provides enough safety. But there's not only Intel HW out there, and we'd rather be on a safe side. If any CPU instruction execution would collide with the patching, it'd be trapped by the int3 breakpoint and redirected to the provided "handler" (which would typically mean just skipping over the patched region, acting as "nop" has been there, in case we are doing nop -> jump and jump -> nop transitions). Ftrace has been using this very technique since 08d636b ("ftrace/x86: Have arch x86_64 use breakpoints instead of stop machine") for ages already, and jump labels are another obvious potential user of this. Based on activities of Masami Hiramatsu a few years ago.

Without this patch Mackerel does not boot via the Mask ROM over USB (r_usb_boot) - this since non-DT boot was broken ages ago in commit: 0ce53cd ARM: mach-shmobile: Use DT_MACHINE for mackerel Signed-off-by: Magnus Damm Signed-off-by: Simon Horman --- arch/arm/boot/compressed/head-shmobile.S | 43 +++++++++++++++++++-- arch/arm/mach-shmobile/include/mach/zboot.h | 2 - 2 files changed, 39 insertions(+), 6 deletions(-) diff --git a/arch/arm/boot/compressed/head-shmobile.S b/arch/arm/boot/compressed/head-shmobile.S index e2d636336b7c..e7f80928949c 100644 --- a/arch/arm/boot/compressed/head-shmobile.S +++ b/arch/arm/boot/compressed/head-shmobile.S @@ -55,12 +55,47 @@ __tmp_stack: __continue: #endif /* CONFIG_ZBOOT_ROM_MMC || CONFIG_ZBOOT_ROM_SH_MOBILE_SDHI */ - /* Set board ID necessary for boot */ - ldr r7, 1f @ Set machine type register - mov r8, #0 @ pass null pointer as atag + adr r0, dtb_info + ldmia r0, {r1, r3, r4, r5, r7} + + sub r0, r0, r1 @ calculate the delta offset + add r5, r5, r0 @ _edata + + ldr lr, [r5, #0] @ check if valid DTB is present + cmp lr, r3 + bne 0f + + add r9, r7, #31 @ rounded up to a multiple + bic r9, r9, #31 @ ... of 32 bytes + + add r6, r9, r5 @ copy from _edata + add r9, r9, r4 @ to MEMORY_START + +1: ldmdb r6!, {r0 - r3, r10 - r12, lr} + cmp r6, r5 + stmdb r9!, {r0 - r3, r10 - r12, lr} + bhi 1b + + /* Success: Zero board ID, pointer to start of memory for atag/dtb */ + mov r7, #0 + mov r8, r4 b 2f -1 : .long MACH_TYPE + .align 2 +dtb_info: + .word dtb_info +#ifndef __ARMEB__ + .word 0xedfe0dd0 @ sig is 0xd00dfeed big endian +#else + .word 0xd00dfeed +#endif + .word MEMORY_START + .word _edata + .word 0x4000 @ maximum DTB size +0: + /* Failure: Zero board ID, NULL atag/dtb */ + mov r7, #0 + mov r8, #0 @ pass null pointer as atag 2 : #endif /* CONFIG_ZBOOT_ROM */ diff --git a/arch/arm/mach-shmobile/include/mach/zboot.h b/arch/arm/mach-shmobile/include/mach/zboot.h index f2d8744c1f14..c3c4669a2d72 100644 --- a/arch/arm/mach-shmobile/include/mach/zboot.h +++ b/arch/arm/mach-shmobile/include/mach/zboot.h @@ -1,7 +1,6 @@ #ifndef ZBOOT_H #define ZBOOT_H -#include #include /************************************************** @@ -11,7 +10,6 @@ **************************************************/ #ifdef CONFIG_MACH_MACKEREL -#define MACH_TYPE MACH_TYPE_MACKEREL #define MEMORY_START 0x40000000 #include "mach/head-mackerel.txt" #else -- GitLab From 14bd03e08831a52035e601ae85b05a4849214ec4 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Thu, 4 Jul 2013 21:13:27 +0200 Subject: [PATCH 0395/9245] ARM: mach-shmobile: mackerel: Use gpio-backlight Replace the backlight callback with a gpio-backlight platform device.
