s390: Remove protvirt and kvm config guards for uv codeRemoving the CONFIG_PROTECTED_VIRTUALIZATION_GUEST ifdefs and configoption as well as CONFIG_KVM ifdefs in uv files.Having this configurable has been more of a pain than a help.It's time to remove the ifdefs and the config option.Signed-off-by: Janosch Frank Acked-by: Christian Borntraeger Acked-by: Heiko Carstens Signed-off-by: Vasily Gorbik List of files: /linux-6.15/drivers/s390/char/Kconfig

4689752c - drivers/s390/char: Add Ultravisor io device

Mon, 16 May 2022 11:33:35 +0000

drivers/s390/char: Add Ultravisor io deviceThis patch adds a new miscdevice to expose some Ultravisor functionsto userspace. Userspace can send IOCTLs to the uvdevice that will thenemit a corresponding Ultravisor Call and hands the result over touserspace. The uvdevice is available if the Ultravisor Call facility ispresent.Userspace can call the Retrieve Attestation MeasurementUltravisor Call using IOCTLs on the uvdevice.The uvdevice will do some sanity checks first.Then, copy the request data to kernel space, build the UVCB,perform the UV call, and copy the result back to userspace.Signed-off-by: Steffen Eiden Reviewed-by: Janosch Frank Reviewed-by: Claudio Imbrenda Link: https://lore.kernel.org/kvm/20220516113335.338212-1-seiden@linux.ibm.com/Message-Id: <20220516113335.338212-1-seiden@linux.ibm.com>Signed-off-by: Janosch Frank (whitespace and tristate fixes, pick) List of files: /linux-6.15/drivers/s390/char/Kconfig

3f429842 - s390/vmcp: make use of contiguous memory allocator

Mon, 07 Aug 2017 13:16:15 +0000

s390/vmcp: make use of contiguous memory allocatorIf memory is fragmented it is unlikely that large order memoryallocations succeed. This has been an issue with the vmcp devicedriver since a long time, since it requires large physical contiguousmemory ares for large responses.To hopefully resolve this issue make use of the contiguous memoryallocator (cma). This patch adds a vmcp specific vmcp cma area with adefault size of 4MB. The size can be changed either via theVMCP_CMA_SIZE config option at compile time or with the "vmcp_cma"kernel parameter (e.g. "vmcp_cma=16m").For any vmcp response buffers larger than 16k memory from the cma areawill be allocated. If such an allocation fails, there is a fallback tothe buddy allocator.Signed-off-by: Heiko Carstens Signed-off-by: Martin Schwidefsky List of files: /linux-6.15/drivers/s390/char/Kconfig

s390/sclp_cpi: remove sclp_cpi module in favor of sysfs interfaceSince commit c05ffc4f2b20 ("[S390] sclp: sysfs interface forSCLP cpi"), which was made 2008 the user can specify a systemand sysplex name through the /sys/firmware/cpi interface. Inaddition to sysplex and system name, the user can also overridethe system type and system version.Because the syfs interface is easier to use and allows thesettings to be updated, the sclp_cpi module becomes obsoleteand can be removed.Signed-off-by: Hendrik Brueckner Acked-by: Christian Borntraeger Acked-by: Heiko Carstens Signed-off-by: Martin Schwidefsky List of files: /linux-6.15/drivers/s390/char/Kconfig

5a79859a - s390: remove 31 bit support

Thu, 12 Feb 2015 12:08:27 +0000

s390: remove 31 bit supportRemove the 31 bit support in order to reduce maintenance cost andeffectively remove dead code. Since a couple of years there is nodistribution left that comes with a 31 bit kernel.The 31 bit kernel also has been broken since more than a year beforeanybody noticed. In addition I added a removal warning to the kernelshown at ipl for 5 minutes: a960062e5826 ("s390: add 31 bit warningmessage") which let everybody know about the plan to remove 31 bitcode. We didn't get any response.Given that the last 31 bit only machine was introduced in 1999 let'sremove the code.Anybody with 31 bit user space code can still use the compat mode.Signed-off-by: Heiko Carstens Signed-off-by: Martin Schwidefsky List of files: /linux-6.15/drivers/s390/char/Kconfig

tty: Added a CONFIG_TTY option to allow removal of TTYThe option allows you to remove TTY and compile without errors. Thissaves space on systems that won't support TTY interfaces anyway.bloat-o-meter output is below.The bulk of this patch consists of Kconfig changes adding "depends onTTY" to various serial devices and similar drivers that require the TTYlayer. Ideally, these dependencies would occur on a common intermediatesymbol such as SERIO, but most drivers "select SERIO" rather than"depends on SERIO", and "select" does not respect dependencies.bloat-o-meter output comparing our previous minimal to new minimal byremoving TTY.
