 modprobe
 ========
 
-This gives the full path of the modprobe command which the kernel will
-use to load modules. This can be used to debug module loading
-requests::
+The full path to the usermode helper for autoloading kernel modules,
+by default "/sbin/modprobe".  This binary is executed when the kernel
+requests a module.  For example, if userspace passes an unknown
+filesystem type to mount(), then the kernel will automatically request
+the corresponding filesystem module by executing this usermode helper.
+This usermode helper should insert the needed module into the kernel.
+
+This sysctl only affects module autoloading.  It has no effect on the
+ability to explicitly insert modules.
+
+This sysctl can be used to debug module loading requests::
 
     echo '#! /bin/sh' > /tmp/modprobe
     echo 'echo "$@" >> /tmp/modprobe.log' >> /tmp/modprobe
···
     chmod a+x /tmp/modprobe
     echo /tmp/modprobe > /proc/sys/kernel/modprobe
 
-This only applies when the *kernel* is requesting that the module be
-loaded; it won't have any effect if the module is being loaded
-explicitly using ``modprobe`` from userspace.
+Alternatively, if this sysctl is set to the empty string, then module
+autoloading is completely disabled.  The kernel will not try to
+execute a usermode helper at all, nor will it call the
+kernel_module_request LSM hook.
 
+If CONFIG_STATIC_USERMODEHELPER=y is set in the kernel configuration,
+then the configured static usermode helper overrides this sysctl,
+except that the empty string is still accepted to completely disable
+module autoloading as described above.

-======================
+Assumptions
+===========
 
 This document assumes the reader has basic knowledge in network drivers
 and in general interrupt moderation.
 
 
-Part I: Introduction
-======================
+Introduction
+============
 
 Dynamic Interrupt Moderation (DIM) (in networking) refers to changing the
 interrupt moderation configuration of a channel in order to optimize packet
···
 increase bandwidth over reducing interrupt rate.
 
 
-Part II: The Net DIM Algorithm
-===============================
+Net DIM Algorithm
+=================
 
 Each iteration of the Net DIM algorithm follows these steps:
-1. Calculates new data sample.
-2. Compares it to previous sample.
-3. Makes a decision - suggests interrupt moderation configuration fields.
-4. Applies a schedule work function, which applies suggested configuration.
+
+#. Calculates new data sample.
+#. Compares it to previous sample.
+#. Makes a decision - suggests interrupt moderation configuration fields.
+#. Applies a schedule work function, which applies suggested configuration.
 
 The first two steps are straightforward, both the new and the previous data are
 supplied by the driver registered to Net DIM. The previous data is the new data
···
 under some conditions.
 
 
-Part III: Registering a Network Device to DIM
-==============================================
+Registering a Network Device to DIM
+===================================
 
-Net DIM API exposes the main function net_dim(struct dim *dim,
-struct dim_sample end_sample). This function is the entry point to the Net
+Net DIM API exposes the main function net_dim().
+This function is the entry point to the Net
 DIM algorithm and has to be called every time the driver would like to check if
 it should change interrupt moderation parameters. The driver should provide two
-data structures: struct dim and struct dim_sample. Struct dim
+data structures: :c:type:`struct dim <dim>` and
+:c:type:`struct dim_sample <dim_sample>`. :c:type:`struct dim <dim>`
 describes the state of DIM for a specific object (RX queue, TX queue,
 other queues, etc.). This includes the current selected profile, previous data
 samples, the callback function provided by the driver and more.
-Struct dim_sample describes a data sample, which will be compared to the
-data sample stored in struct dim in order to decide on the algorithm's next

 the driver.

 interrupt. Since Net DIM has a built-in moderation and it might decide to skip
 iterations under certain conditions, there is no need to moderate the net_dim()
 calls as well. As mentioned above, the driver needs to provide an object of type
-struct dim to the net_dim() function call. It is advised for each entity
-using Net DIM to hold a struct dim as part of its data structure and use it
-as the main Net DIM API object. The struct dim_sample should hold the latest
+:c:type:`struct dim <dim>` to the net_dim() function call. It is advised for
+each entity using Net DIM to hold a :c:type:`struct dim <dim>` as part of its
+data structure and use it as the main Net DIM API object.
+The :c:type:`struct dim_sample <dim_sample>` should hold the latest
 bytes, packets and interrupts count. No need to perform any calculations, just
 include the raw data.
 
···
 the proper state in order to move to the next iteration.
 
 
-Part IV: Example
-=================
+Example
+=======
 
 The following code demonstrates how to register a driver to Net DIM. The actual
 usage is not complete but it should make the outline of the usage clear.
 
-my_driver.c:
+.. code-block:: c
 
-#include <linux/dim.h>
+  #include <linux/dim.h>
 
-/* Callback for net DIM to schedule on a decision to change moderation */
-void my_driver_do_dim_work(struct work_struct *work)
-{
+  /* Callback for net DIM to schedule on a decision to change moderation */
+  void my_driver_do_dim_work(struct work_struct *work)
+  {
 	/* Get struct dim from struct work_struct */
 	struct dim *dim = container_of(work, struct dim,
 				       work);
···
 
 	/* Signal net DIM work is done and it should move to next iteration */
 	dim->state = DIM_START_MEASURE;
-}
+  }
 
-/* My driver's interrupt handler */
-int my_driver_handle_interrupt(struct my_driver_entity *my_entity, ...)
-{
+  /* My driver's interrupt handler */
+  int my_driver_handle_interrupt(struct my_driver_entity *my_entity, ...)
+  {
 	...
 	/* A struct to hold current measured data */
 	struct dim_sample dim_sample;
···
 	/* Call net DIM */
 	net_dim(&my_entity->dim, dim_sample);
 	...
-}
+  }
 
-/* My entity's initialization function (my_entity was already allocated) */
-int my_driver_init_my_entity(struct my_driver_entity *my_entity, ...)
-{
+  /* My entity's initialization function (my_entity was already allocated) */
+  int my_driver_init_my_entity(struct my_driver_entity *my_entity, ...)
+  {
 	...
 	/* Initiate struct work_struct with my driver's callback function */
 	INIT_WORK(&my_entity->dim.work, my_driver_do_dim_work);
 	...
-}
+  }

 must be __BOOT_DS; interrupt must be disabled; %rsi must hold the base
 address of the struct boot_params.
 
-EFI Handover Protocol
-=====================
+EFI Handover Protocol (deprecated)
+==================================
 
 This protocol allows boot loaders to defer initialisation to the EFI
 boot stub. The boot loader is required to load the kernel/initrd(s)
 from the boot media and jump to the EFI handover protocol entry point
 which is hdr->handover_offset bytes from the beginning of
 startup_{32,64}.
+
+The boot loader MUST respect the kernel's PE/COFF metadata when it comes
+to section alignment, the memory footprint of the executable image beyond
+the size of the file itself, and any other aspect of the PE/COFF header
+that may affect correct operation of the image as a PE/COFF binary in the
+execution context provided by the EFI firmware.
 
 The function prototype for the handover entry point looks like this::
 
···
 
 The boot loader *must* fill out the following fields in bp::
 
-  - hdr.code32_start
   - hdr.cmd_line_ptr
   - hdr.ramdisk_image (if applicable)
   - hdr.ramdisk_size  (if applicable)
 
 All other fields should be zero.
+
+NOTE: The EFI Handover Protocol is deprecated in favour of the ordinary PE/COFF
+      entry point, combined with the LINUX_EFI_INITRD_MEDIA_GUID based initrd
+      loading protocol (refer to [0] for an example of the bootloader side of
+      this), which removes the need for any knowledge on the part of the EFI
+      bootloader regarding the internal representation of boot_params or any
+      requirements/limitations regarding the placement of the command line
+      and ramdisk in memory, or the placement of the kernel image itself.
