Message-ID: <20250415122832.982610-1-joel@jms.id.au> Date: Tue, 15 Apr 2025 21:58:31 +0930 From: Joel Stanley <joel@....id.au> To: Paul Walmsley <paul.walmsley@...ive.com>, Palmer Dabbelt <palmer@...belt.com>, Albert Ou <aou@...s.berkeley.edu>, Alexandre Ghiti <alex@...ti.fr> Cc: Hal Feng <hal.feng@...rfivetech.com>, Michael Ellerman <mpe@...erman.id.au>, Arnd Bergmann <arnd@...db.de>, linux-kernel@...r.kernel.org, linux-riscv@...ts.infradead.org Subject: [PATCH] riscv: defconfig: Remove EXPERT The setting of EXPERT is a leftover from when the riscv defconfig was first added. As mentioned in the EXPERT Kconfig help text it is not intended to be set in the usual case. Upon removal a bunch of intrusive debug-related kernel options are no longer set, which is good. A few may want to come back in the future but let those be advocated for on a case by case basis. NAMESPACES, SYSFS_SYSCALL and MEDIA_SUPPORT_FILTER default on and thus fall out of the defconfig. Set VIDEO_CADENCE_CSI2RX=y to ensure VIDEO_CADENCE_CSI2RX stays enabled. Set DEBUG_KERNEL=y in line with other arch defconfigs. This turns on tracing. Signed-off-by: Joel Stanley <joel@....id.au> --- This supersedes https://lore.kernel.org/all/20250404062235.671872-1-joel@jms.id.au/ as it is a fix for the root cause: by removing EXPERT causes MEDIA_SUPPORT_FILTER=y like most other defconfigs and thus the unwanted MEDIA drivers stay disabled. To view the change between the old .config and the new, use a recipe such as: make ARCH=riscv defconfig && cp .config config-before-removing-expert git am 0001-riscv-defconfig-Remove-EXPERT.patch make
