From 66c6413c69abb7335efc4ea07f4c811c042704b6 Mon Sep 17 00:00:00 2001 From: Kyösti Mälkki Date: Sat, 19 Dec 2020 16:19:44 +0200 Subject: ACPI: Refactor ChromeOS specific ACPI GNVS MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The layout of GNVS has expectation for a fixed size array for chromeos_acpi_t. This allows us to reduce the exposure of . If chromeos_acpi_t was the last entry in struct global_nvs padding at the end is also removed. If device_nvs_t exists, place a properly sized reserve for chromeos_acpi_t in the middle. Allocation from cbmem is adjusted such that it matches exactly the OperationRegion size defined inside the ASL.
