paths in the kernel. Tests are intended to be run after building, installing
and booting a kernel.
+Kselftest from mainline can be run on older stable kernels. Running tests
+from mainline offers the best coverage. Several test rings run mainline
+kselftest suite on stable releases. The reason is that when a new test
+gets added to test existing code to regression test a bug, we should be
+able to run that test on an older kernel. Hence, it is important to keep
+code that can still test an older kernel and make sure it skips the test
+gracefully on newer releases.
+
You can find additional information on Kselftest framework, how to
write new tests using the framework on Kselftest wiki:

-Garbage collect fbdev scrolling acceleration
---------------------------------------------
-
-Scroll acceleration has been disabled in fbcon. Now it works as the old
-SCROLL_REDRAW mode. A ton of code was removed in fbcon.c and the hook bmove was
-removed from fbcon_ops.
-Remaining tasks:
-
-- a bunch of the hooks in fbcon_ops could be removed or simplified by calling
- directly instead of the function table (with a switch on p->rotate)
-
-- fb_copyarea is unused after this, and can be deleted from all drivers
-
-- after that, fb_copyarea can be deleted from fb_ops in include/linux/fb.h as
- well as cfb_copyarea
-
-Note that not all acceleration code can be deleted, since clearing and cursor
-support is still accelerated, which might be good candidates for further
-deletion projects.

+ Affected Cortex-A510 may corrupt SPSR_EL2 when the a step exception is

+
+ When these conditions occur, the SPSR_EL2 value is unchanged from the

+
+ Affected Cortex-A510 core might cause an inconsistent view on whether trace is
+ prohibited within the CPU. As a result, the trace buffer or trace buffer state
+ might be corrupted. This happens after TRBE buffer has been enabled by setting
+ TRBLIMITR_EL1.E, followed by just a single context synchronization event before
+ execution changes from a context, in which trace is prohibited to one where it
+ isn't, or vice versa. In these mentioned conditions, the view of whether trace
+ is prohibited is inconsistent between parts of the CPU, and the trace buffer or
+ the trace buffer state might be corrupted.
+
+ Work around this in the driver by preventing an inconsistent view of whether the
+ trace is prohibited or not based on TRBLIMITR_EL1.E by immediately following a
+ change to TRBLIMITR_EL1.E with at least one ISB instruction before an ERET, or

- * to read bytes of instruction which caused #NPF. In this case,
- * GuestIntrBytes field of the VMCB on a VMEXIT will incorrectly
- * return 0 instead of the correct guest instruction bytes.
- *
- * This happens because CPU microcode reading instruction bytes
- * uses a special opcode which attempts to read data using CPL=0
- * privileges. The microcode reads CS:RIP and if it hits a SMAP
- * fault, it gives up and returns no instruction bytes.
+ * When CPU raises #NPF on guest data access and vCPU CR4.SMAP=1, it is
+ * possible that CPU microcode implementing DecodeAssist will fail to
+ * read guest memory at CS:RIP and vmcb.GuestIntrBytes will incorrectly
+ * be '0'. This happens because microcode reads CS:RIP using a _data_
+ * loap uop with CPL=0 privileges. If the load hits a SMAP #PF, ucode
+ * gives up and does not fill the instruction bytes buffer.
*
- * Detection:
- * We reach here in case CPU supports DecodeAssist, raised #NPF and
- * returned 0 in GuestIntrBytes field of the VMCB.
- * First, errata can only be triggered in case vCPU CR4.SMAP=1.
- * Second, if vCPU CR4.SMEP=1, errata could only be triggered
- * in case vCPU CPL==3 (Because otherwise guest would have triggered
- * a SMEP fault instead of #NPF).
- * Otherwise, vCPU CR4.SMEP=0, errata could be triggered by any vCPU CPL.
- * As most guests enable SMAP if they have also enabled SMEP, use above
- * logic in order to attempt minimize false-positive of detecting errata
- * while still preserving all cases semantic correctness.
+ * As above, KVM reaches this point iff the VM is an SEV guest, the CPU
+ * supports DecodeAssist, a #NPF was raised, KVM's page fault handler
+ * triggered emulation (e.g. for MMIO), and the CPU returned 0 in the
+ * GuestIntrBytes field of the VMCB.
*
- * Workaround:
- * To determine what instruction the guest was executing, the hypervisor
- * will have to decode the instruction at the instruction pointer.
+ * This does _not_ mean that the erratum has been encountered, as the
+ * DecodeAssist will also fail if the load for CS:RIP hits a legitimate
+ * #PF, e.g. if the guest attempt to execute from emulated MMIO and
+ * encountered a reserved/not-present #PF.
*
- * In non SEV guest, hypervisor will be able to read the guest
- * memory to decode the instruction pointer when insn_len is zero
- * so we return true to indicate that decoding is possible.
+ * To hit the erratum, the following conditions must be true:
+ * 1. CR4.SMAP=1 (obviously).
+ * 2. CR4.SMEP=0 || CPL=3. If SMEP=1 and CPL<3, the erratum cannot
+ * have been hit as the guest would have encountered a SMEP
+ * violation #PF, not a #NPF.
+ * 3. The #NPF is not due to a code fetch, in which case failure to
+ * retrieve the instruction bytes is legitimate (see abvoe).
*
- * But in the SEV guest, the guest memory is encrypted with the
- * guest specific key and hypervisor will not be able to decode the
- * instruction pointer so we will not able to workaround it. Lets
- * print the error and request to kill the guest.
+ * In addition, don't apply the erratum workaround if the #NPF occurred
+ * while translating guest page tables (see below).

+ This option enables the fbcon (framebuffer text-based) hardware
+ acceleration for graphics drivers which were written for the fbdev
+ graphics interface.
+
+ On modern machines, on mainstream machines (like x86-64) or when
+ using a modern Linux distribution those fbdev drivers usually aren't used.
+ So enabling this option wouldn't have any effect, which is why you want
+ to disable this option on such newer machines.
+
+ If you compile this kernel for older machines which still require the
+ fbdev drivers, you may want to say Y.
+
+ If unsure, select n.

+ * SCROLL_REDRAW imageblit No No
+ * SCROLL_PAN_REDRAW imageblit Yes No
+ * SCROLL_WRAP_REDRAW imageblit No Yes
+ *
+ * (SCROLL_WRAP_REDRAW is not implemented yet)
+ *
+ * In general, fbcon will choose the best scrolling
+ * method based on the rule below:
+ *
+ * Pan/Wrap > accel imageblit > accel copyarea >
+ * soft imageblit > (soft copyarea)
+ *
+ * Exception to the rule: Pan + accel copyarea is
+ * preferred over Pan + accel imageblit.
+ *
+ * The above is typical for PCI/AGP cards. Unless
+ * overridden, fbcon will never use soft copyarea.
+ *
+ * If you need to override the above rule, set the
+ * appropriate flags in fb_info->flags. For example,
+ * to prefer copyarea over imageblit, set
+ * FBINFO_READS_FAST.
+ *
+ * Other notes:
+ * + use the hardware engine to move the text
+ * (hw-accelerated copyarea() and fillrect())
+ * + use hardware-supported panning on a large virtual screen
+ * + amifb can not only pan, but also wrap the display by N lines
+ * (i.e. visible line i = physical line (i+N) % yres).
+ * + read what's already rendered on the screen and
+ * write it in a different place (this is cfb_copyarea())
+ * + re-render the text to the screen
+ *
+ * Whether to use wrapping or panning can only be figured out at
+ * runtime (when we know whether our font height is a multiple
+ * of the pan/wrap step)
