+Description:
+ Perform SMBIOS calls on supported Dell machines.
+ through the Dell ACPI-WMI interface.
+
+ IOCTL's and buffer formats are defined in:
+ <uapi/linux/wmi.h>
+
+ 1) To perform an SMBIOS call from userspace, you'll need to
+ first determine the minimum size of the calling interface
+ buffer for your machine.
+ Platforms that contain larger buffers can return larger
+ objects from the system firmware.
+ Commonly this size is either 4k or 32k.
+
+ To determine the size of the buffer read() a u64 dword from
+ the WMI character device /dev/wmi/dell-smbios.
+
+ 2) After you've determined the minimum size of the calling
+ interface buffer, you can allocate a structure that represents
+ the structure documented above.
+
+ 3) In the 'length' object store the size of the buffer you
+ determined above and allocated.
+
+ 4) In this buffer object, prepare as necessary for the SMBIOS
+ call you're interested in. Typically SMBIOS buffers have
+ "class", "select", and "input" defined to values that coincide
+ with the data you are interested in.
+ Documenting class/select/input values is outside of the scope
+ of this documentation. Check with the libsmbios project for
+ further documentation on these values.
+
+ 6) Run the call by using ioctl() as described in the header.
+
+ 7) The output will be returned in the buffer object.
+
+ 8) Be sure to free up your allocated object.

+-------------
+Many OEMs include a method that can be used to force the power of a

+
+ To force the power to on, write 1 to this attribute file.
+ To disable force power, write 0 to this attribute file.

-
-CONFIG_VIDEO_COMPACT - enables compacting of the video mode list. If there

+MULTICOPY 원자성
+----------------
-이행성(transitivity)은 실제의 컴퓨터 시스템에서 항상 제공되지는 않는, 순서
-맞추기에 대한 상당히 직관적인 개념입니다. 다음의 예가 이행성을 보여줍니다:
+Multicopy 원자성은 실제의 컴퓨터 시스템에서 항상 제공되지는 않는, 순서 맞추기에
+대한 상당히 직관적인 개념으로, 특정 스토어가 모든 CPU 들에게 동시에 보여지게
+됨을, 달리 말하자면 모든 CPU 들이 모든 스토어들이 보여지는 순서를 동의하게 되는
+것입니다. 하지만, 완전한 multicopy 원자성의 사용은 가치있는 하드웨어
+최적화들을 무능하게 만들어버릴 수 있어서, 보다 완화된 형태의 ``다른 multicopy
+원자성'' 라는 이름의, 특정 스토어가 모든 -다른- CPU 들에게는 동시에 보여지게
+하는 보장을 대신 제공합니다. 이 문서의 뒷부분들은 이 완화된 형태에 대해 논하게
+됩니다만, 단순히 ``multicopy 원자성'' 이라고 부르겠습니다.
+
+다음의 예가 multicopy 원자성을 보입니다:
CPU 1 CPU 2 CPU 3

-전에 이루어졌음을 의미합니다. 그럼 "CPU 3 의 X 로드는 0을 리턴할 수 있나요?"
+CPU 2 의 Y 로의 스토어에 사용되는 X 로드의 결과가 1 이었고 CPU 3 의 Y 로드가
+1을 리턴했다고 해봅시다. 이는 CPU 1 의 X 로의 스토어가 CPU 2 의 X 로부터의
+로드를 앞서고 CPU 2 의 Y 로의 스토어가 CPU 3 의 Y 로부터의 로드를 앞섬을
+의미합니다. 또한, 여기서의 메모리 배리어들은 CPU 2 가 자신의 로드를 자신의
+스토어 전에 수행하고, CPU 3 가 Y 로부터의 로드를 X 로부터의 로드 전에 수행함을
+보장합니다. 그럼 "CPU 3 의 X 로부터의 로드는 0 을 리턴할 수 있을까요?"
-CPU 2 의 X 로드는 CPU 1 의 스토어 후에 이루어졌으니, CPU 3 의 X 로드는 1을
-리턴하는게 자연스럽습니다. 이런 생각이 이행성의 한 예입니다: CPU A 에서 실행된
-로드가 CPU B 에서의 같은 변수에 대한 로드를 뒤따른다면, CPU A 의 로드는 CPU B
-의 로드가 내놓은 값과 같거나 그 후의 값을 내놓아야 합니다.
+CPU 3 의 X 로드가 CPU 2 의 로드보다 뒤에 이루어졌으므로, CPU 3 의 X 로부터의
+로드는 1 을 리턴한다고 예상하는게 당연합니다. 이런 예상은 multicopy
+원자성으로부터 나옵니다: CPU B 에서 수행된 로드가 CPU A 의 같은 변수로부터의
+로드를 뒤따른다면 (그리고 CPU A 가 자신이 읽은 값으로 먼저 해당 변수에 스토어
+하지 않았다면) multicopy 원자성을 제공하는 시스템에서는, CPU B 의 로드가 CPU A
+의 로드와 같은 값 또는 그 나중 값을 리턴해야만 합니다. 하지만, 리눅스 커널은
+시스템들이 multicopy 원자성을 제공할 것을 요구하지 않습니다.
-리눅스 커널에서 범용 배리어의 사용은 이행성을 보장합니다. 따라서, 앞의 예에서
-CPU 2 의 X 로드가 1을, Y 로드는 0을 리턴했다면, CPU 3 의 X 로드는 반드시 1을
-리턴합니다.
+앞의 범용 메모리 배리어의 사용은 모든 multicopy 원자성의 부족을 보상해줍니다.
+앞의 예에서, CPU 2 의 X 로부터의 로드가 1 을 리턴했고 CPU 3 의 Y 로부터의

- LOAD Y LOAD X
+ STORE X=1 r1=LOAD X (reads 1) LOAD Y (reads 1)
+ <데이터 의존성> <읽기 배리어>
+ STORE Y=r1 LOAD X (reads 0)
-이 코드는 이행성을 갖지 않습니다: 이 예에서는, CPU 2 의 X 로드가 1을
-리턴하고, Y 로드는 0을 리턴하지만 CPU 3 의 X 로드가 0을 리턴하는 것도 완전히
-합법적입니다.
+이 변화는 non-multicopy 원자성이 만연하게 합니다: 이 예에서, CPU 2 의 X

+의 X 로부터의 로드가 0 을 리턴하는게 완전히 합법적입니다.
-CPU 2 의 읽기 배리어가 자신의 읽기는 순서를 맞춰줘도, CPU 1 의 스토어와의
-순서를 맞춰준다고는 보장할 수 없다는게 핵심입니다. 따라서, CPU 1 과 CPU 2 가

-쓴 값에 좀 빨리 접근할 수 있을 것입니다. 따라서 CPU 1 과 CPU 2 의 접근으로

+핵심은, CPU 2 의 데이터 의존성이 자신의 로드와 스토어를 순서짓지만, CPU 1 의

+ * Licensed under the GPL v2
+ *
+ * vdso2c requires stripped and unstripped input. It would be trivial
+ * to fully strip the input in here, but, for reasons described below,
+ * we need to write a section table. Doing this is more or less
+ * equivalent to dropping all non-allocatable sections, but it's
+ * easier to let objcopy handle that instead of doing it ourselves.
+ * If we ever need to do something fancier than what objcopy provides,
+ * it would be straightforward to add here.
+ *
+ * We keep a section table for a few reasons:
+ *
+ * Binutils has issues debugging the vDSO: it reads the section table to
+ * find SHT_NOTE; it won't look at PT_NOTE for the in-memory vDSO, which
+ * would break build-id if we removed the section table. Binutils
+ * also requires that shstrndx != 0. See:
+ * https://sourceware.org/bugzilla/show_bug.cgi?id=17064
+ *
+ * elfutils might not look for PT_NOTE if there is a section table at
+ * all. I don't know whether this matters for any practical purpose.
+ *
+ * For simplicity, rather than hacking up a partial section table, we
+ * just write a mostly complete one. We omit non-dynamic symbols,
+ * though, since they're rather large.
+ *
+ * Once binutils gets fixed, we might be able to drop this for all but
+ * the 64-bit vdso, since build-id only works in kernel RPMs, and
+ * systems that update to new enough kernel RPMs will likely update
+ * binutils in sync. build-id has never worked for home-built kernel
+ * RPMs without manual symlinking, and I suspect that no one ever does
+ * that.

+ * mmap_address_hint_valid - Validate the address hint of mmap
+ * @addr: Address hint
+ * @len: Mapping length
+ *
+ * Check whether @addr and @addr + @len result in a valid mapping.
+ *
+ * On 32bit this only checks whether @addr + @len is <= TASK_SIZE.
+ *
+ * On 64bit with 5-level page tables another sanity check is required
+ * because mappings requested by mmap(@addr, 0) which cross the 47-bit
+ * virtual address boundary can cause the following theoretical issue:
+ *
+ * An application calls mmap(addr, 0), i.e. without MAP_FIXED, where @addr
+ * is below the border of the 47-bit address space and @addr + @len is
+ * above the border.
+ *
+ * With 4-level paging this request succeeds, but the resulting mapping
+ * address will always be within the 47-bit virtual address space, because
+ * the hint address does not result in a valid mapping and is
+ * ignored. Hence applications which are not prepared to handle virtual
+ * addresses above 47-bit work correctly.
+ *
+ * With 5-level paging this request would be granted and result in a
+ * mapping which crosses the border of the 47-bit virtual address
+ * space. If the application cannot handle addresses above 47-bit this
+ * will lead to misbehaviour and hard to diagnose failures.
+ *
+ * Therefore ignore address hints which would result in a mapping crossing
+ * the 47-bit virtual address boundary.
+ *
+ * Note, that in the same scenario with MAP_FIXED the behaviour is
+ * different. The request with @addr < 47-bit and @addr + @len > 47-bit
+ * fails on a 4-level paging machine but succeeds on a 5-level paging
+ * machine. It is reasonable to expect that an application does not rely on
+ * the failure of such a fixed mapping request, so the restriction is not
+ * applied.

+ * The information given in the Armada 388 functional spec is complex.

+ * reduce down to (we shall rename "Offset" as "val" here):
+ *
+ * val = (f_ideal / f_measured - 1) / resolution where f_ideal = 32768

+ * Converting to time, f = 1/t:
+ * val = (t_measured / t_ideal - 1) / resolution where t_ideal = 1/32768
+ *
+ * => t_measured / t_ideal = val * resolution + 1
+ *
+ * "offset" in the RTC interface is defined as:
+ * t = t0 * (1 + offset * 1e-9)
+ * where t is the desired period, t0 is the measured period with a zero
+ * offset, which is t_measured above. With t0 = t_measured and t = t_ideal,
+ * offset = (t_ideal / t_measured - 1) / 1e-9
+ *
+ * => t_ideal / t_measured = offset * 1e-9 + 1
+ *
+ * so:
+ *
+ * offset * 1e-9 + 1 = 1 / (val * resolution + 1)
+ *
+ * We want "resolution" to be an integer, so resolution = R * 1e-9, giving
+ * offset = 1e18 / (val * R + 1e9) - 1e9
+ * val = (1e18 / (offset + 1e9) - 1e9) / R

+ION BUFFER SHARING UTILITY
+==========================
+File: ion_test.sh : Utility to test ION driver buffer sharing mechanism.
+Author: Pintu Kumar <pintu.ping@gmail.com>
+
+Introduction:
+-------------
+This is a test utility to verify ION buffer sharing in user space
+between 2 independent processes.
+It uses unix domain socket (with SCM_RIGHTS) as IPC to transfer an FD to
+another process to share the same buffer.
+This utility demonstrates how ION buffer sharing can be implemented between
+two user space processes, using various heap types.
+The following heap types are supported by ION driver.
+ION_HEAP_TYPE_SYSTEM (0)
+ION_HEAP_TYPE_SYSTEM_CONTIG (1)
+ION_HEAP_TYPE_CARVEOUT (2)
+ION_HEAP_TYPE_CHUNK (3)
+ION_HEAP_TYPE_DMA (4)
+
+By default only the SYSTEM and SYSTEM_CONTIG heaps are supported.
+Each heap is associated with the respective heap id.
+This utility is designed in the form of client/server program.
+The server part (ionapp_export) is the exporter of the buffer.
+It is responsible for creating an ION client, allocating the buffer based on
+the heap id, writing some data to this buffer and then exporting the FD
+(associated with this buffer) to another process using socket IPC.
+This FD is called as buffer FD (which is different than the ION client FD).
+
+The client part (ionapp_import) is the importer of the buffer.
+It retrives the FD from the socket data and installs into its address space.
+This new FD internally points to the same kernel buffer.
+So first it reads the data that is stored in this buffer and prints it.
+Then it writes the different size of data (it could be different data) to the
+same buffer.
+Finally the buffer FD must be closed by both the exporter and importer.
+Thus the same kernel buffer is shared among two user space processes using
+ION driver and only one time allocation.
+
+Prerequisite:
+-------------
+This utility works only if /dev/ion interface is present.
+The following configs needs to be enabled in kernel to include ion driver.
+CONFIG_ANDROID=y
+CONFIG_STAGING=y
+CONFIG_ION=y
+CONFIG_ION_SYSTEM_HEAP=y
+
+This utility requires to be run as root user.
+
+
+Compile and test:
+-----------------
+This utility is made to be run as part of kselftest framework in kernel.
+To compile and run using kselftest you can simply do the following from the
+kernel top directory.
+linux$ make TARGETS=android kselftest
+Or you can also use:
+linux$ make -C tools/testing/selftests TARGETS=android run_tests
+Using the selftest it can directly execute the ion_test.sh script to test the
+buffer sharing using ion system heap.
+Currently the heap size is hard coded as just 10 bytes inside this script.
+You need to be a root user to run under selftest.
+
+You can also compile and test manually using the following steps:
+ion$ make
+These will generate 2 executable: ionapp_export, ionapp_import
+Now you can run the export and import manually by specifying the heap type
+and the heap size.
+You can also directly execute the shell script to run the test automatically.
+Simply use the following command to run the test.
+ion$ sudo ./ion_test.sh
+
+Test Results:
+-------------
+The utility is verified on Ubuntu-32 bit system with Linux Kernel 4.14.
+Here is the snapshot of the test result using kselftest.
+
+linux# make TARGETS=android kselftest

+/*
+ * How KVM uses GICv4 (insert rude comments here):
+ *
+ * The vgic-v4 layer acts as a bridge between several entities:
+ * - The GICv4 ITS representation offered by the ITS driver
+ * - VFIO, which is in charge of the PCI endpoint
+ * - The virtual ITS, which is the only thing the guest sees
+ *
+ * The configuration of VLPIs is triggered by a callback from VFIO,
+ * instructing KVM that a PCI device has been configured to deliver
+ * MSIs to a vITS.
+ *
+ * kvm_vgic_v4_set_forwarding() is thus called with the routing entry,
+ * and this is used to find the corresponding vITS data structures
+ * (ITS instance, device, event and irq) using a process that is
+ * extremely similar to the injection of an MSI.
+ *
+ * At this stage, we can link the guest's view of an LPI (uniquely
+ * identified by the routing entry) and the host irq, using the GICv4
+ * driver mapping operation. Should the mapping succeed, we've then
+ * successfully upgraded the guest's LPI to a VLPI. We can then start
+ * with updating GICv4's view of the property table and generating an
+ * INValidation in order to kickstart the delivery of this VLPI to the
+ * guest directly, without software intervention. Well, almost.
+ *
+ * When the PCI endpoint is deconfigured, this operation is reversed
+ * with VFIO calling kvm_vgic_v4_unset_forwarding().
+ *
+ * Once the VLPI has been mapped, it needs to follow any change the
+ * guest performs on its LPI through the vITS. For that, a number of
+ * command handlers have hooks to communicate these changes to the HW:
+ * - Any invalidation triggers a call to its_prop_update_vlpi()
+ * - The INT command results in a irq_set_irqchip_state(), which
+ * generates an INT on the corresponding VLPI.
+ * - The CLEAR command results in a irq_set_irqchip_state(), which
+ * generates an CLEAR on the corresponding VLPI.
+ * - DISCARD translates into an unmap, similar to a call to
+ * kvm_vgic_v4_unset_forwarding().
+ * - MOVI is translated by an update of the existing mapping, changing
+ * the target vcpu, resulting in a VMOVI being generated.
+ * - MOVALL is translated by a string of mapping updates (similar to
+ * the handling of MOVI). MOVALL is horrible.
+ *
+ * Note that a DISCARD/MAPTI sequence emitted from the guest without
+ * reprogramming the PCI endpoint after MAPTI does not result in a
+ * VLPI being mapped, as there is no callback from VFIO (the guest
+ * will get the interrupt via the normal SW injection). Fixing this is
+ * not trivial, and requires some horrible messing with the VFIO
+ * internals. Not fun. Don't do that.
+ *
+ * Then there is the scheduling. Each time a vcpu is about to run on a
+ * physical CPU, KVM must tell the corresponding redistributor about
+ * it. And if we've migrated our vcpu from one CPU to another, we must
+ * tell the ITS (so that the messages reach the right redistributor).
+ * This is done in two steps: first issue a irq_set_affinity() on the
+ * irq corresponding to the vcpu, then call its_schedule_vpe(). You
+ * must be in a non-preemptible context. On exit, another call to
+ * its_schedule_vpe() tells the redistributor that we're done with the
+ * vcpu.
+ *
+ * Finally, the doorbell handling: Each vcpu is allocated an interrupt
+ * which will fire each time a VLPI is made pending whilst the vcpu is
+ * not running. Each time the vcpu gets blocked, the doorbell
+ * interrupt gets enabled. When the vcpu is unblocked (for whatever
+ * reason), the doorbell interrupt is disabled.
