qemu: Bump to version 2.11.0
Use the latest QEMU release 2.11. Remove all patches that are no longer required as they have been merged into the 2.11 releaese. One patch had to be updated to apply to the 2.11 tree. This also applies a linux user patch to avoid webkitgtk build hangs. Signed-off-by: Alistair Francis <alistair.francis@xilinx.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

-Subject: [PATCH 01/12] tpm: Clean up driver registration & lookup
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-We have a strict separation between enum TpmType and be_drivers[]:
-
-* TpmType may have any number of members. It just happens to have one.
-
-* tpm_register_driver() uses the first empty slot in be_drivers[].
-
- If you register more than tpm_models[] has space,
- tpm_register_driver() fails. Its caller silently ignores the
- failure.
-
- If you register more than one with a given TpmType,
- tpm_display_backend_drivers() will shows all of them, but
- tpm_driver_find_by_type() and tpm_get_backend_driver() will find
- only the one one that registered first.
-
-Since we only ever register one driver, and be_drivers[] has space for
-just that one, this contraption even works.
-
-Turn be_drivers[] into a straight map from enum TpmType to driver.
-Much simpler, and has a decent chance to actually work should we ever
-acquire additional drivers.
-
-While there, use qapi_enum_parse() in tpm_get_backend_driver().

-TPMDriverOps inside TPMBackend is not required, as it is supposed to be a class

-Move thread handling inside TPMBackend, this way backend implementations need

-'handle_request()' class method that always been called from a thread.
-
-This change made tpm_backend_int.h kind of useless, hence removed it.

- own methods
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Initialize and free TPMBackend data members in it's own instance_init() and
-instance_finalize methods.
-
-Took the opportunity to remove unneeded destroy() method from TpmDriverOps
-interface as TPMBackend is a Qemu Object, we can use object_unref() inplace of
-tpm_backend_destroy() to free the backend object, hence removed destroy() from
-TPMDriverOps interface.

-Subject: [PATCH 07/12] tpm backend: Add new api to read backend TpmInfo
-
-TPM configuration options are backend implementation details and shall not be
-part of base TPMBackend object, and these shall not be accessed directly outside
-of the class, hence added a new interface method, get_tpm_options() to
-TPMDriverOps., which shall be implemented by the derived classes to return
-configured tpm options.
-
-A new tpm backend api - tpm_backend_query_tpm() which uses _get_tpm_options() to
-prepare TpmInfo.

-Subject: [PATCH 10/12] tpm: Added support for TPM emulator
-
-This change introduces a new TPM backend driver that can communicate with
-swtpm(software TPM emulator) using unix domain socket interface. QEMU talks to
-TPM emulator using QEMU's socket-based chardev backend device.
-
-Swtpm uses two Unix sockets for communications, one for plain TPM commands and
-responses, and one for out-of-band control messages. QEMU passes data socket to
-be used over the control channel.
-
-The swtpm and associated tools can be found here:
- https://github.com/stefanberger/swtpm
-
-The swtpm's control channel protocol specification can be found here:
- https://github.com/stefanberger/swtpm/wiki/Control-Channel-Specification
-
-Usage:
- # setup TPM state directory
- mkdir /tmp/mytpm
- chown -R tss:root /tmp/mytpm
- /usr/bin/swtpm_setup --tpm-state /tmp/mytpm --createek
-
- # Ask qemu to use TPM emulator with given tpm state directory
- qemu-system-x86_64 \
- [...] \
- -chardev socket,id=chrtpm,path=/tmp/swtpm-sock \
- -tpmdev emulator,id=tpm0,chardev=chrtpm \
- -device tpm-tis,tpmdev=tpm0 \
- [...]

-Content-Type: text/plain; charset=UTF-8

-EBADMSG was only added to OpenBSD very recently. To make QEMU compilable
-on older OpenBSD versions use EMSGSIZE instead when a mismatch between
-number of received bytes and message size indicated in the header was

-Return -EMSGSIZE and convert all other errnos in the same functions to

+Subject: [PATCH] linux-user: Fix webkitgtk hangs on 32-bit x86 target
+
+Since commit "linux-user: Tidy and enforce reserved_va initialization"
+(18e80c55bb6ec17c05ec0ba717ec83933c2bfc07) the Yocto webkitgtk build
+hangs when cross compiling for 32-bit x86 on a 64-bit x86 machine using
+musl.
+
+To fix the issue reduce the MAX_RESERVED_VA macro to be a closer match
+to what it was before the problematic commit.
+

-I've tracked down what I think is a problem causing qemu-system-ppc
-to hang whilst booting images.
-
-I believe the decrementer timer stops receiving interrupts so
-tasks in our images hang indefinitely as the timer stopped.
-
-It can be summed up with this line of debug:
-
-ppc_set_irq: 0x55b4e0d562f0 n_IRQ 8 level 1 => pending 00000100req 00000004
-
-It should normally read:
-
-ppc_set_irq: 0x55b4e0d562f0 n_IRQ 8 level 1 => pending 00000100req 00000002
-
-The question is why CPU_INTERRUPT_EXITTB ends up being set when the
-lines above this log message clearly sets CPU_INTERRUPT_HARD (via
-cpu_interrupt() ).
-
-I note in cpu.h:
-
- /* updates protected by BQL */
- uint32_t interrupt_request;
-
-(for struct CPUState)
-
-The ppc code does "cs->interrupt_request |= CPU_INTERRUPT_EXITTB" in 5
-places, 3 in excp_helper.c and 2 in helper_regs.h. In all cases,
-g_assert(qemu_mutex_iothread_locked()); fails. If I do something like:
-
-if (!qemu_mutex_iothread_locked()) {
- qemu_mutex_lock_iothread();
- cpu_interrupt(cs, CPU_INTERRUPT_EXITTB);
- qemu_mutex_unlock_iothread();
-} else {
- cpu_interrupt(cs, CPU_INTERRUPT_EXITTB);
-}
-
-in these call sites then I can no longer lock qemu up with my test
-case.
-
-I suspect the _HARD setting gets overwritten which stops the
-decrementer interrupts being delivered.
