From c5ffe6c8dd5623f1893f54971e23e7c1ddf094ee Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Fri, 19 Feb 2021 14:45:50 +0000 Subject: hw/misc/iotkit-sysctl: Handle SSE-300 changes to PDCM_PD_*_SENSE registers MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The sysctl PDCM_PD_*_SENSE registers control various power domains in the system and allow the guest to configure which conditions keep a power domain awake and what power state to use when the domain is in a low power state. QEMU doesn't model power domains, so for us these registers are dummy reads-as-written implementations. The SSE-300 has a different power domain setup, so the set of registers is slightly different: Offset SSE-200 SSE-300 --------------------------------------------------- 0x200 PDCM_PD_SYS_SENSE PDCM_PD_SYS_SENSE 0x204 reserved PDCM_PD_CPU0_SENSE 0x208 reserved reserved 0x20c PDCM_PD_SRAM0_SENSE reserved 0x210 PDCM_PD_SRAM1_SENSE reserved 0x214 PDCM_PD_SRAM2_SENSE PDCM_PD_VMR0_SENSE 0x218 PDCM_PD_SRAM3_SENSE PDCM_PD_VMR1_SENSE Offsets 0x200 and 0x208 are the same for both, so handled in a previous commit; here we deal with 0x204, 0x20c, 0x210, 0x214, 0x218. (We can safely add new lines to the SSE300 vmstate because no board uses this device in an SSE300 yet.)
