ps2: fix scancodes sent for Alt-Print key combination (aka SysRq)
The 'Print' key is special in the AT set 1 / set 2 scancode definitions.
An unmodified 'Print' key is supposed to send
AT Set 1: e0 2a e0 37 (Down) e0 b7 e0 aa (Up)
AT Set 2: e0 12 e0 7c (Down) e0 f0 7c e0 f0 12 (Up)
which QEMU gets right. When pressed in combination with the 'Alt_L' or 'Alt_R'
keys (which signify SysRq), the scancodes are required to follow a different
scheme. With Alt_L, the expected sequences are
AT set 1: 38, 54 (Down) d4, b8 (Up)
AT set 2: 11, 84 (Down) f0 84, f0 11 (Up)
And with Alt_R
AT set 1: e0 38, 54 (Down) d4, e0 b8 (Up)
AT set 2: e0 11, 84 (Down) f0 84, f0 e0 11 (Up)
It is actually slightly more complicated than that, because (according results
of 'showkey -s', keyboards will in fact first release the currently pressed
modifier before sending the sequence above (which effectively re-presses &
then releases the modifier) and finally re-press the original modifier
afterwards. IOW, with Alt_L we need to send
AT set 1: b8, 38, 54 (Down) d4, b8, 38 (Up)
AT set 2: f0 11, 11, 84 (Down) f0 84, f0 11, 11 (Up)
And with Alt_R
AT set 1: e0 b8, e0 38, 54 (Down) d4, e0 b8, e0 38 (Up)
AT set 2: e0 f0 11, e0 11, 84 (Down) f0 84, e0 f0 11, e0 11 (Up)
The AT set 3 scancodes have no special handling for Alt-Print.
Rather than fixing the handling of the 'print' key in the ps2 driver to consider
the Alt modifiers, way back, a patch was commited that defined an extra 'sysrq'
key name:
commit f2289cb6924afc97b2a75d21bfc9217024d11741
Author: balrog <balrog@c046a42c-6fe2-441c-8c8c-71466251a162>

Add sysrq to key names known by "sendkey".
Adding sysrq keycode to the table enabling running sysrq debugging in
the guest via the monitor sendkey command, like:
(qemu) sendkey alt-sysrq-t
Tested on x86-64 target and Linux guest.
Signed-off-by: Ryan Harper <ryanh@us.ibm.com>
With this patch QEMU would send
AT set 1: 38, 54 (Down) d4, b8 (Up)
AT set 2: 11, 84 (Down) f0 84, f0 11 (Up)
but this doesn't match what actual real keyboards send, as it is not releasing
the original modifier & pressing it again afterwards. In addition the original
problem remains, and a new problem was added:
- The sequence 'alt-print-t' is still broken, acting as if 'print-t' was
requested
- The sequence 'sysrq-t' is broken, injecting an undefine scancode sequence
tot he guest os (bare 0x54)
To deal with this mess we make these changes to the ps2 code, so that we track
the state of modifier keys (Alt, Shift, Ctrl - both left & right). Then we can
vary what scancodes are sent for Q_KEY_CODE_PRINT according to the Alt key
modifier state
Interestingly, it appears that of operating systems I've checked (Linux, FreeBSD
and OpenSolaris), none of them actually bother to validate the full sequences
for a unmodified 'Print' key. They all just ignore the leading "e0 2a" and
trigger based off "e0 37" alone. The latter two byte sequence is what keyboards
send with 'Print' is combined with 'Shift' or 'Ctrl' modifiers.

ps2: fix scancodes sent for Alt-Print key combination (aka SysRq)
The 'Print' key is special in the AT set 1 / set 2 scancode definitions.
An unmodified 'Print' key is supposed to send
AT Set 1: e0 2a e0 37 (Down) e0 b7 e0 aa (Up)
AT Set 2: e0 12 e0 7c (Down) e0 f0 7c e0 f0 12 (Up)
which QEMU gets right. When pressed in combination with the 'Alt_L' or 'Alt_R'
keys (which signify SysRq), the scancodes are required to follow a different
scheme. With Alt_L, the expected sequences are
AT set 1: 38, 54 (Down) d4, b8 (Up)
AT set 2: 11, 84 (Down) f0 84, f0 11 (Up)
And with Alt_R
AT set 1: e0 38, 54 (Down) d4, e0 b8 (Up)
AT set 2: e0 11, 84 (Down) f0 84, f0 e0 11 (Up)
It is actually slightly more complicated than that, because (according results
of 'showkey -s', keyboards will in fact first release the currently pressed
modifier before sending the sequence above (which effectively re-presses &
then releases the modifier) and finally re-press the original modifier
afterwards. IOW, with Alt_L we need to send
AT set 1: b8, 38, 54 (Down) d4, b8, 38 (Up)
AT set 2: f0 11, 11, 84 (Down) f0 84, f0 11, 11 (Up)
And with Alt_R
AT set 1: e0 b8, e0 38, 54 (Down) d4, e0 b8, e0 38 (Up)
AT set 2: e0 f0 11, e0 11, 84 (Down) f0 84, e0 f0 11, e0 11 (Up)
The AT set 3 scancodes have no special handling for Alt-Print.
Rather than fixing the handling of the 'print' key in the ps2 driver to consider
the Alt modifiers, way back, a patch was commited that defined an extra 'sysrq'
key name:
commit f2289cb6924afc97b2a75d21bfc9217024d11741
Author: balrog <balrog@c046a42c-6fe2-441c-8c8c-71466251a162>
Date: Wed Jun 4 10:14:16 2008 +0000
Add sysrq to key names known by "sendkey".
Adding sysrq keycode to the table enabling running sysrq debugging in
the guest via the monitor sendkey command, like:
(qemu) sendkey alt-sysrq-t
Tested on x86-64 target and Linux guest.
Signed-off-by: Ryan Harper <ryanh@us.ibm.com>
With this patch QEMU would send
AT set 1: 38, 54 (Down) d4, b8 (Up)
AT set 2: 11, 84 (Down) f0 84, f0 11 (Up)
but this doesn't match what actual real keyboards send, as it is not releasing
the original modifier & pressing it again afterwards. In addition the original
problem remains, and a new problem was added:
- The sequence 'alt-print-t' is still broken, acting as if 'print-t' was
requested
- The sequence 'sysrq-t' is broken, injecting an undefine scancode sequence
tot he guest os (bare 0x54)
To deal with this mess we make these changes to the ps2 code, so that we track
the state of modifier keys (Alt, Shift, Ctrl - both left & right). Then we can
vary what scancodes are sent for Q_KEY_CODE_PRINT according to the Alt key
modifier state
Interestingly, it appears that of operating systems I've checked (Linux, FreeBSD
and OpenSolaris), none of them actually bother to validate the full sequences
for a unmodified 'Print' key. They all just ignore the leading "e0 2a" and
trigger based off "e0 37" alone. The latter two byte sequence is what keyboards
send with 'Print' is combined with 'Shift' or 'Ctrl' modifiers.

qapi: Don't special-case simple union wrappers
Simple unions were carrying a special case that hid their 'data'
QMP member from the resulting C struct, via the hack method
QAPISchemaObjectTypeVariant.simple_union_type(). But by using
the work we started by unboxing flat union and alternate
branches, coupled with the ability to visit the members of an
implicit type, we can now expose the simple union's implicit
type in qapi-types.h:
| struct q_obj_ImageInfoSpecificQCow2_wrapper {
| ImageInfoSpecificQCow2 *data;
| };
|
| struct q_obj_ImageInfoSpecificVmdk_wrapper {
| ImageInfoSpecificVmdk *data;
| };
...
| struct ImageInfoSpecific {
| ImageInfoSpecificKind type;
| union { /* union tag is @type */
| void *data;
|- ImageInfoSpecificQCow2 *qcow2;
|- ImageInfoSpecificVmdk *vmdk;
|+ q_obj_ImageInfoSpecificQCow2_wrapper qcow2;
|+ q_obj_ImageInfoSpecificVmdk_wrapper vmdk;
| } u;
| };
Doing this removes asymmetry between QAPI's QMP side and its
C side (both sides now expose 'data'), and means that the
treatment of a simple union as sugar for a flat union is now
equivalent in both languages (previously the two approaches used
a different layer of dereferencing, where the simple union could
be converted to a flat union with equivalent C layout but
different {} on the wire, or to an equivalent QMP wire form
but with different C representation). Using the implicit type
also lets us get rid of the simple_union_type() hack.
Of course, now all clients of simple unions have to adjust from
using su->u.member to using su->u.member.data; while this touches
a number of files in the tree, some earlier cleanup patches
helped minimize the change to the initialization of a temporary
variable rather than every single member access. The generated
qapi-visit.c code is also affected by the layout change:
|@@ -7393,10 +7393,10 @@ void visit_type_ImageInfoSpecific_member
| }
| switch (obj->type) {
| case IMAGE_INFO_SPECIFIC_KIND_QCOW2:
|- visit_type_ImageInfoSpecificQCow2(v, "data", &obj->u.qcow2, &err);
|+ visit_type_q_obj_ImageInfoSpecificQCow2_wrapper_members(v, &obj->u.qcow2, &err);

ps2: fix scancodes sent for Alt-Print key combination (aka SysRq)
The 'Print' key is special in the AT set 1 / set 2 scancode definitions.
An unmodified 'Print' key is supposed to send
AT Set 1: e0 2a e0 37 (Down) e0 b7 e0 aa (Up)
AT Set 2: e0 12 e0 7c (Down) e0 f0 7c e0 f0 12 (Up)
which QEMU gets right. When pressed in combination with the 'Alt_L' or 'Alt_R'
keys (which signify SysRq), the scancodes are required to follow a different
scheme. With Alt_L, the expected sequences are
AT set 1: 38, 54 (Down) d4, b8 (Up)
AT set 2: 11, 84 (Down) f0 84, f0 11 (Up)
And with Alt_R
AT set 1: e0 38, 54 (Down) d4, e0 b8 (Up)
AT set 2: e0 11, 84 (Down) f0 84, f0 e0 11 (Up)
It is actually slightly more complicated than that, because (according results
of 'showkey -s', keyboards will in fact first release the currently pressed
modifier before sending the sequence above (which effectively re-presses &
then releases the modifier) and finally re-press the original modifier
afterwards. IOW, with Alt_L we need to send
AT set 1: b8, 38, 54 (Down) d4, b8, 38 (Up)
AT set 2: f0 11, 11, 84 (Down) f0 84, f0 11, 11 (Up)
And with Alt_R
AT set 1: e0 b8, e0 38, 54 (Down) d4, e0 b8, e0 38 (Up)
AT set 2: e0 f0 11, e0 11, 84 (Down) f0 84, e0 f0 11, e0 11 (Up)
The AT set 3 scancodes have no special handling for Alt-Print.
Rather than fixing the handling of the 'print' key in the ps2 driver to consider
the Alt modifiers, way back, a patch was commited that defined an extra 'sysrq'
key name:
commit f2289cb6924afc97b2a75d21bfc9217024d11741
Author: balrog <balrog@c046a42c-6fe2-441c-8c8c-71466251a162>

Add sysrq to key names known by "sendkey".
Adding sysrq keycode to the table enabling running sysrq debugging in
the guest via the monitor sendkey command, like:
(qemu) sendkey alt-sysrq-t
Tested on x86-64 target and Linux guest.
Signed-off-by: Ryan Harper <ryanh@us.ibm.com>
With this patch QEMU would send
AT set 1: 38, 54 (Down) d4, b8 (Up)
AT set 2: 11, 84 (Down) f0 84, f0 11 (Up)
but this doesn't match what actual real keyboards send, as it is not releasing
the original modifier & pressing it again afterwards. In addition the original
problem remains, and a new problem was added:
- The sequence 'alt-print-t' is still broken, acting as if 'print-t' was
requested
- The sequence 'sysrq-t' is broken, injecting an undefine scancode sequence
tot he guest os (bare 0x54)
To deal with this mess we make these changes to the ps2 code, so that we track
the state of modifier keys (Alt, Shift, Ctrl - both left & right). Then we can
vary what scancodes are sent for Q_KEY_CODE_PRINT according to the Alt key
modifier state
Interestingly, it appears that of operating systems I've checked (Linux, FreeBSD
and OpenSolaris), none of them actually bother to validate the full sequences
for a unmodified 'Print' key. They all just ignore the leading "e0 2a" and
trigger based off "e0 37" alone. The latter two byte sequence is what keyboards
send with 'Print' is combined with 'Shift' or 'Ctrl' modifiers.

AT set 1: 38, 54 (Down) d4, b8 (Up)
AT set 2: 11, 84 (Down) f0 84, f0 11 (Up)
And with Alt_R
AT set 1: e0 38, 54 (Down) d4, e0 b8 (Up)
AT set 2: e0 11, 84 (Down) f0 84, f0 e0 11 (Up)
It is actually slightly more complicated than that, because (according results
of 'showkey -s', keyboards will in fact first release the currently pressed
modifier before sending the sequence above (which effectively re-presses &
then releases the modifier) and finally re-press the original modifier
afterwards. IOW, with Alt_L we need to send
AT set 1: b8, 38, 54 (Down) d4, b8, 38 (Up)
AT set 2: f0 11, 11, 84 (Down) f0 84, f0 11, 11 (Up)

AT set 2: e0 f0 11, e0 11, 84 (Down) f0 84, e0 f0 11, e0 11 (Up)
The AT set 3 scancodes have no special handling for Alt-Print.
Rather than fixing the handling of the 'print' key in the ps2 driver to consider
the Alt modifiers, way back, a patch was commited that defined an extra 'sysrq'
key name:

Add sysrq to key names known by "sendkey".
Adding sysrq keycode to the table enabling running sysrq debugging in
the guest via the monitor sendkey command, like:
(qemu) sendkey alt-sysrq-t
Tested on x86-64 target and Linux guest.
Signed-off-by: Ryan Harper <ryanh@us.ibm.com>
With this patch QEMU would send
AT set 1: 38, 54 (Down) d4, b8 (Up)
AT set 2: 11, 84 (Down) f0 84, f0 11 (Up)
but this doesn't match what actual real keyboards send, as it is not releasing
the original modifier & pressing it again afterwards. In addition the original
problem remains, and a new problem was added:
- The sequence 'alt-print-t' is still broken, acting as if 'print-t' was
requested
- The sequence 'sysrq-t' is broken, injecting an undefine scancode sequence
tot he guest os (bare 0x54)
To deal with this mess we make these changes to the ps2 code, so that we track
the state of modifier keys (Alt, Shift, Ctrl - both left & right). Then we can
vary what scancodes are sent for Q_KEY_CODE_PRINT according to the Alt key
modifier state
Interestingly, it appears that of operating systems I've checked (Linux, FreeBSD
and OpenSolaris), none of them actually bother to validate the full sequences
for a unmodified 'Print' key. They all just ignore the leading "e0 2a" and
trigger based off "e0 37" alone. The latter two byte sequence is what keyboards
send with 'Print' is combined with 'Shift' or 'Ctrl' modifiers.

qapi: Don't let implicit enum MAX member collide
Now that we guarantee the user doesn't have any enum values
beginning with a single underscore, we can use that for our
own purposes. Renaming ENUM_MAX to ENUM__MAX makes it obvious
that the sentinel is generated.
This patch was mostly generated by applying a temporary patch:
|diff --git a/scripts/qapi.py b/scripts/qapi.py
|index e6d014b..b862ec9 100644
|--- a/scripts/qapi.py
|+++ b/scripts/qapi.py
|@@ -1570,6 +1570,7 @@ const char *const %(c_name)s_lookup[] = {
| max_index = c_enum_const(name, 'MAX', prefix)
| ret += mcgen('''
| [%(max_index)s] = NULL,
|+// %(max_index)s
| };
| ''',
| max_index=max_index)
then running:
$ cat qapi-{types,event}.c tests/test-qapi-types.c |
sed -n 's,^// \(.*\)MAX,s|\1MAX|\1_MAX|g,p' > list
$ git grep -l _MAX | xargs sed -i -f list
The only things not generated are the changes in scripts/qapi.py.
Rejecting enum members named 'MAX' is now useless, and will be dropped
in the next patch.

qapi: Don't special-case simple union wrappers
Simple unions were carrying a special case that hid their 'data'
QMP member from the resulting C struct, via the hack method
QAPISchemaObjectTypeVariant.simple_union_type(). But by using
the work we started by unboxing flat union and alternate
branches, coupled with the ability to visit the members of an
implicit type, we can now expose the simple union's implicit
type in qapi-types.h:
| struct q_obj_ImageInfoSpecificQCow2_wrapper {
| ImageInfoSpecificQCow2 *data;
| };
|
| struct q_obj_ImageInfoSpecificVmdk_wrapper {
| ImageInfoSpecificVmdk *data;
| };
...
| struct ImageInfoSpecific {
| ImageInfoSpecificKind type;
| union { /* union tag is @type */
| void *data;
|- ImageInfoSpecificQCow2 *qcow2;
|- ImageInfoSpecificVmdk *vmdk;
|+ q_obj_ImageInfoSpecificQCow2_wrapper qcow2;
|+ q_obj_ImageInfoSpecificVmdk_wrapper vmdk;
| } u;
| };
Doing this removes asymmetry between QAPI's QMP side and its
C side (both sides now expose 'data'), and means that the
treatment of a simple union as sugar for a flat union is now
equivalent in both languages (previously the two approaches used
a different layer of dereferencing, where the simple union could
be converted to a flat union with equivalent C layout but
different {} on the wire, or to an equivalent QMP wire form
but with different C representation). Using the implicit type
also lets us get rid of the simple_union_type() hack.
Of course, now all clients of simple unions have to adjust from
using su->u.member to using su->u.member.data; while this touches
a number of files in the tree, some earlier cleanup patches
helped minimize the change to the initialization of a temporary
variable rather than every single member access. The generated
qapi-visit.c code is also affected by the layout change:

different {} on the wire, or to an equivalent QMP wire form
but with different C representation). Using the implicit type
also lets us get rid of the simple_union_type() hack.
Of course, now all clients of simple unions have to adjust from
using su->u.member to using su->u.member.data; while this touches
a number of files in the tree, some earlier cleanup patches
helped minimize the change to the initialization of a temporary
variable rather than every single member access. The generated
qapi-visit.c code is also affected by the layout change:

ps2: fix scancodes sent for Alt-Print key combination (aka SysRq)
The 'Print' key is special in the AT set 1 / set 2 scancode definitions.
An unmodified 'Print' key is supposed to send
AT Set 1: e0 2a e0 37 (Down) e0 b7 e0 aa (Up)
AT Set 2: e0 12 e0 7c (Down) e0 f0 7c e0 f0 12 (Up)
which QEMU gets right. When pressed in combination with the 'Alt_L' or 'Alt_R'
keys (which signify SysRq), the scancodes are required to follow a different
scheme. With Alt_L, the expected sequences are
AT set 1: 38, 54 (Down) d4, b8 (Up)
AT set 2: 11, 84 (Down) f0 84, f0 11 (Up)
And with Alt_R
AT set 1: e0 38, 54 (Down) d4, e0 b8 (Up)
AT set 2: e0 11, 84 (Down) f0 84, f0 e0 11 (Up)
It is actually slightly more complicated than that, because (according results
of 'showkey -s', keyboards will in fact first release the currently pressed
modifier before sending the sequence above (which effectively re-presses &
then releases the modifier) and finally re-press the original modifier
afterwards. IOW, with Alt_L we need to send
AT set 1: b8, 38, 54 (Down) d4, b8, 38 (Up)
AT set 2: f0 11, 11, 84 (Down) f0 84, f0 11, 11 (Up)
And with Alt_R
AT set 1: e0 b8, e0 38, 54 (Down) d4, e0 b8, e0 38 (Up)
AT set 2: e0 f0 11, e0 11, 84 (Down) f0 84, e0 f0 11, e0 11 (Up)
The AT set 3 scancodes have no special handling for Alt-Print.
Rather than fixing the handling of the 'print' key in the ps2 driver to consider
the Alt modifiers, way back, a patch was commited that defined an extra 'sysrq'
key name:
commit f2289cb6924afc97b2a75d21bfc9217024d11741
Author: balrog <balrog@c046a42c-6fe2-441c-8c8c-71466251a162>
Date: Wed Jun 4 10:14:16 2008 +0000
Add sysrq to key names known by "sendkey".
Adding sysrq keycode to the table enabling running sysrq debugging in
the guest via the monitor sendkey command, like:
(qemu) sendkey alt-sysrq-t
Tested on x86-64 target and Linux guest.
Signed-off-by: Ryan Harper <ryanh@us.ibm.com>
With this patch QEMU would send
AT set 1: 38, 54 (Down) d4, b8 (Up)
AT set 2: 11, 84 (Down) f0 84, f0 11 (Up)
but this doesn't match what actual real keyboards send, as it is not releasing
the original modifier & pressing it again afterwards. In addition the original
problem remains, and a new problem was added:
- The sequence 'alt-print-t' is still broken, acting as if 'print-t' was
requested
- The sequence 'sysrq-t' is broken, injecting an undefine scancode sequence
tot he guest os (bare 0x54)
To deal with this mess we make these changes to the ps2 code, so that we track
the state of modifier keys (Alt, Shift, Ctrl - both left & right). Then we can
vary what scancodes are sent for Q_KEY_CODE_PRINT according to the Alt key
modifier state
Interestingly, it appears that of operating systems I've checked (Linux, FreeBSD
and OpenSolaris), none of them actually bother to validate the full sequences
for a unmodified 'Print' key. They all just ignore the leading "e0 2a" and
trigger based off "e0 37" alone. The latter two byte sequence is what keyboards
send with 'Print' is combined with 'Shift' or 'Ctrl' modifiers.
