Subject: [PULL 10/12] hw/hppa: Move software power button address to page zero
Date: Mon, 13 Nov 2023 09:32:35 -0800 [thread overview]
Message-ID: <20231113173237.48233-11-richard.henderson@linaro.org> (raw)
In-Reply-To: <20231113173237.48233-1-richard.henderson@linaro.org>
From: Helge Deller <deller@gmx.de>
Something appears to be off between the 64-bit CPU, the 32-bit PDC
(SeaBIOS-hppa firmware), and the 64-bit kernel in addressing the
power button address in high-mapped firmware memory.
Use a 32-bit value at PAGE0->pad0[4] instead.
