Subject: [PATCH 430/434] ui/spice-display: use uintptr_t when casting qxl
|
|
physical addresses
|
|
|
|
The current intptr_t casts are a problem when the address's highest
|
|
bit is 1, and it is cast to a intptr_t and then to uint64_t, such
|
|
as at:
|
|
surface.mem = (intptr_t)ssd->buf;
|
|
|
|
This causes the sign bit to be extended which causes a wrong address to
|
|
be passed on to spice, which then complains when it gets the wrong
|
|
slot_id number, since the slot_id is taken from the higher bits.
|
|
|
|
The assertion happens early - during the first primary surface creation.
|
|
|
|
This fixes running "-vga qxl -spice" with 32 bit compiled
|
|
qemu-system-i386.
