=Comment: #0================================================= Emily J. Ratliff <ratliff.com> - 1. Feature Overview: Feature Id: [201734] a. Name of Feature: TTY terminal server over IUCV (kernel) b. Feature Description Implement client & server for a TTY terminal server under z/VM using IUCV as communication vehicle. This line item corresponds to the terminal client running on the numerous guests. The terminal client is a Linux tty / console driver with a fixed device node. Additional Comments: This kernel feature requires a userspace part that is feature: 201735 - TTY terminal server over IUCV - userspace 2. Feature Details: Sponsor: zSeries Architectures: s390x Arch Specificity: Purely Arch Specific Code Affects Core Kernel: Yes Affects Kernel Modules: Yes Delivery Mechanism: Backport Category: Kernel Request Type: Kernel - Enhancement from IBM d. Upstream Acceptance: In Progress Sponsor Priority 1 f. Severity: High IBM Confidential: no Code Contribution: IBM code g. Component Version Target: 2.6.29 3. Business Case Customer requirement to solve restriction to access to the Linux console for many Linux administrators concurrently and they find the z/VM 3270 interface inadequate for the 200+ Linux admins due to the inability to use common programs such as vi from this interface. The customer has a requirement that the Linux system that needs to have its console accessed, will have its TCPIP stack shutdown, so the solution can not involve an IP connection to that system IP stack. 4.

As discussed in yesterdays Red Hat call Status: The code for this feature has to be expected late Actual outlook is ca. mid of March The reason we try to get this done is because this is a customer request and the IBM assessment is there are other customers in the same situation. This impacts common code IBM development is checking that this does not break kabi Plan: Send code when available and assess doability on Red Hat site If this does not break kabi -> code avail. mid march may be containable, if that date does not slip Note: The implementation of this feature is a question of capacity that late in the process therefore this might have to go to 5.5 if no slot can be found.
Updating PM score.
