powerpc/64s: Default to 64K pages for 64 bit book3s

2021-10-27T11:31:22Z

For 64-bit book3s the default should be 64K as that's what modern CPUs are designed for. The following defconfigs already set CONFIG_PPC_64K_PAGES: cell_defconfig pasemi_defconfig powernv_defconfig ppc64_defconfig pseries_defconfig skiroot_defconfig The have the option removed from the defconfig, as it is now the default. The defconfigs that now need to set CONFIG_PPC_4K_PAGES to maintain their existing behaviour are: g5_defconfig maple_defconfig microwatt_defconfig ps3_defconfig Signed-off-by: Joel Stanley Signed-off-by: Michael Ellerman BugLink: https://github.com/linuxppc/issues/issues/109 Link: https://lore.kernel.org/r/20211015001649.45591-1-joel@jms.id.au

arch: powerpc: Stop building and using oprofile

2021-01-29T04:35:51Z

The "oprofile" user-space tools don't use the kernel OPROFILE support any more, and haven't in a long time. User-space has been converted to the perf interfaces. This commits stops building oprofile for powerpc and removes any reference to it from directories in arch/powerpc/ apart from arch/powerpc/oprofile, which will be removed in the next commit (this is broken into two commits as the size of the commit became very big, ~5k lines). Note that the member "oprofile_cpu_type" in "struct cpu_spec" isn't removed as it was also used by other parts of the code.

scsi: sr: remove references to BLK_DEV_SR_VENDOR, leave it enabled

2020-02-24T19:59:01Z

This kernel configuration is basically enabling/disabling sr driver quirks detection. While these quirks are for fairly rare devices (very old CD burners, and a glucometer), the additional detection of these models is a very minimal amount of code. The logic behind the quirks is always built into the sr driver. This also removes the config from all the defconfig files that are enabling this already.

powerpc/configs: Disable latencytop

latencytop adds almost 4kB to each and every task struct and as such it doesn't deserve to be in our defconfigs. Signed-off-by: Anton Blanchard Signed-off-by: Michael Ellerman

powerpc/configs: Remove useless UEVENT_HELPER_PATH

2019-07-03T05:19:36Z

Remove the CONFIG_UEVENT_HELPER_PATH because: 1. It is disabled since commit 1be01d4a5714 ("driver: base: Disable CONFIG_UEVENT_HELPER by default") as its dependency (UEVENT_HELPER) was made default to 'n', 2. It is not recommended (help message: "This should not be used today [...] creates a high system load") and was kept only for ancient userland, 3. Certain userland specifically requests it to be disabled (systemd README: "Legacy hotplug slows down the system and confuses udev").

powerpc/configs: Don't enable PPC_EARLY_DEBUG in defconfigs

2018-12-20T11:21:20Z

This reverts the remains of commit b9ef7d6b11c1 ("powerpc: Update default configurations"). That commit was proceeded by a commit which added a config option to control use of BOOTX for early debug, ie. PPC_EARLY_DEBUG_BOOTX, and then the update of the defconfigs was intended to not change behaviour by then enabling the new config option. However enabling PPC_EARLY_DEBUG had other consequences, notably causing us to register the udbg console at the end of udbg_early_init(). This means on a system which doesn't have anything that BOOTX can use (most systems), we register the udbg console very early but the bootx code just throws everything away, meaning early boot messages are never printed to the console. What we want to happen is for the udbg console to only be registered later (from setup_arch()) once we've setup udbg_putc, and then all early boot messages will be replayed.

powerpc/configs: Explicitly drop CONFIG_INPUT_MOUSEDEV

2017-08-28T12:10:02Z

In commit 73d8ef76006b ("Input: mousedev - stop offering PS/2 to userspace by default") (Jan 2017), CONFIG_INPUT_MOUSEDEV was switched from default y to default n, with the explanation: Evdev interface has been available for many years and by now everyone is switched to using it, so let's stop offering /dev/input/mouseN and /dev/psaux by default. We had a number of configs which had it enabled, but going by the above explanation probably don't need it enabled anymore. So drop the last remnants of it from our defconfigs.
