[Qemu-devel] [PATCH 1/6] ui/vnc: Only report/use TIGHT_PNG encoding if enabled.

[Qemu-devel] [PATCH 1/6] ui/vnc: Only report/use TIGHT_PNG encoding if enabled.

[Stefan Hajnoczi]

From: Joel Martin <github@martintribe.org>

If TIGHT_PNG is not enabled by the --enable-vnc-png configure flag
then do not report to the client that it is supported.

Also, since TIGHT_PNG is the same as the TIGHT encoding but with the
filter/copy replaced with PNG data, adding it to the supported
encodings list when it is disabled will cause the TIGHT encoding to be
used even though the client requested TIGHT_PNG.

[Qemu-devel] [PATCH 1/6] ui/vnc: Only report/use TIGHT_PNG encoding if enabled.

[Stefan Hajnoczi]

From: Joel Martin <github@martintribe.org>

If TIGHT_PNG is not enabled by the --enable-vnc-png configure flag
then do not report to the client that it is supported.

Also, since TIGHT_PNG is the same as the TIGHT encoding but with the
filter/copy replaced with PNG data, adding it to the supported
encodings list when it is disabled will cause the TIGHT encoding to be
used even though the client requested TIGHT_PNG.

[Stefan Hajnoczi]

From: Peter Maydell <peter.maydell@linaro.org>

Commit 4be403c accidentally defined the target_phys_addr_t type when
building user-mode emulators. Since the type doesn't really make
any sense except for system emulators, avoid defining it when building
in user mode.
